module/apmhttp
editPackage apmhttp provides a low-level net/http
middleware handler. Other web middleware should
typically be based off this.
For each request, a transaction is stored in the request context, which can be obtained via http.Request.Context in your handler.
import ( "go.elastic.co/apm/module/apmhttp/v2" ) func main() { var myHandler http.Handler = ... tracedHandler := apmhttp.Wrap(myHandler) }
The apmhttp handler will recover panics and send them to Elastic APM.
Package apmhttp also provides functions for instrumenting an http.Client
or http.RoundTripper
such that outgoing requests are traced as spans, if the request context includes a transaction.
When performing the request, the enclosing context should be propagated by using
http.Request.WithContext, or a helper, such as those provided by https://golang.org/x/net/context/ctxhttp.
Client spans are not ended until the response body is fully consumed or closed.
If you fail to do either, the span will not be sent.
Always close the response body to ensure HTTP connections can be reused; see func (*Client) Do
.
import ( "net/http" "golang.org/x/net/context/ctxhttp" "go.elastic.co/apm/v2" "go.elastic.co/apm/module/apmhttp/v2" ) var tracingClient = apmhttp.WrapClient(http.DefaultClient) func serverHandler(w http.ResponseWriter, req *http.Request) { // Propagate the transaction context contained in req.Context(). resp, err := ctxhttp.Get(req.Context(), tracingClient, "http://backend.local/foo") if err != nil { apm.CaptureError(req.Context(), err).Send() http.Error(w, "failed to query backend", 500) return } body, err := ioutil.ReadAll(resp.Body) ... } func main() { http.ListenAndServe(":8080", apmhttp.Wrap(http.HandlerFunc(serverHandler))) }
module/apmfasthttp
editPackage apmfasthttp provides a low-level valyala/fasthttp middleware request handler. Other fasthttp-based web middleware should typically be based off this.
For each request, a transaction is stored in the request context, which can be obtained via
fasthttp.RequestCtx in your handler using apm.TransactionFromContext
.
import ( "github.com/valyala/fasthttp" "go.elastic.co/apm/module/apmfasthttp/v2" ) func main() { var myHandler fasthttp.RequestHandler = func(ctx *fasthttp.RequestCtx) { apmCtx := apm.TransactionFromContext(ctx) // ... } tracedHandler := apmfasthttp.Wrap(myHandler) }
The apmfasthttp handler will recover panics and send them to Elastic APM.
module/apmecho
editPackages apmecho and apmechov4 provide middleware for the Echo web framework, versions 3.x and 4.x respectively.
If you are using Echo 4.x (github.com/labstack/echo/v4
), use module/apmechov4
.
For the older Echo 3.x versions (github.com/labstack/echo
), use module/apmecho
.
For each request, a transaction is stored in the request context, which can be obtained via
echo.Context.Request().Context()
in your handler.
import ( echo "github.com/labstack/echo/v4" "go.elastic.co/apm/module/apmechov4/v2" ) func main() { e := echo.New() e.Use(apmechov4.Middleware()) ... }
The middleware will recover panics and send them to Elastic APM, so you do not need to install the echo/middleware.Recover middleware.
module/apmgin
editPackage apmgin provides middleware for the Gin web framework.
For each request, a transaction is stored in the request context, which can be obtained via
gin.Context.Request.Context()
in your handler.
import ( "go.elastic.co/apm/module/apmgin/v2" ) func main() { engine := gin.New() engine.Use(apmgin.Middleware(engine)) ... }
The apmgin middleware will recover panics and send them to Elastic APM, so you do not need to install the gin.Recovery middleware.
module/apmfiber
editPackage apmfiber provides middleware for the Fiber web framework, versions 2.x (v2.18.0 and greater).
For each request, a transaction is stored in the request context, which can be obtained via
fiber.Ctx.Context()
in your handler.
import ( "go.elastic.co/apm/module/apmfiber/v2" ) func main() { app := fiber.New() app.Use(apmfiber.Middleware()) ... }
The apmfiber middleware will recover panics and send them to Elastic APM,
so you do not need to install the fiber recover middleware.
You can disable default behaviour by using WithPanicPropagation
option.
module/apmbeego
editPackage apmbeego provides middleware for the Beego web framework.
For each request, a transaction is stored in the request context, which can be obtained via
beego/context.Context.Request.Context()
in your controller.
import ( "github.com/astaxie/beego" "go.elastic.co/apm/v2" "go.elastic.co/apm/module/apmbeego/v2" ) type thingController struct{beego.Controller} func (c *thingController) Get() { span, _ := apm.StartSpan(c.Ctx.Request.Context(), "thingController.Get", "controller") span.End() ... } func main() { beego.Router("/", &thingController{}) beego.Router("/thing/:id:int", &thingController{}, "get:Get") beego.RunWithMiddleWares("localhost:8080", apmbeego.Middleware()) }
module/apmgorilla
editPackage apmgorilla provides middleware for the Gorilla Mux router.
For each request, a transaction is stored in the request context, which can be obtained via
http.Request.Context()
in your handler.
import ( "github.com/gorilla/mux" "go.elastic.co/apm/module/apmgorilla/v2" ) func main() { router := mux.NewRouter() apmgorilla.Instrument(router) ... }
The apmgorilla middleware will recover panics and send them to Elastic APM, so you do not need to install any other recovery middleware.
module/apmgrpc
editPackage apmgrpc provides server and client interceptors for gRPC-Go. Server interceptors report transactions for each incoming request, while client interceptors report spans for each outgoing request. For each RPC served, a transaction is stored in the context passed into the method.
import ( "go.elastic.co/apm/module/apmgrpc/v2" ) func main() { server := grpc.NewServer( grpc.UnaryInterceptor(apmgrpc.NewUnaryServerInterceptor()), grpc.StreamInterceptor(apmgrpc.NewStreamServerInterceptor()), ) ... conn, err := grpc.Dial(addr, grpc.WithUnaryInterceptor(apmgrpc.NewUnaryClientInterceptor()), grpc.WithStreamInterceptor(apmgrpc.NewStreamClientInterceptor()), ) ... }
The server interceptor can optionally be made to recover panics, in the same way as grpc_recovery. The apmgrpc server interceptor will always send panics it observes as errors to the Elastic APM server. If you want to recover panics but also want to continue using grpc_recovery, then you should ensure that it comes before the apmgrpc interceptor in the interceptor chain, or panics will not be captured by apmgrpc.
server := grpc.NewServer(grpc.UnaryInterceptor( apmgrpc.NewUnaryServerInterceptor(apmgrpc.WithRecovery()), )) ...
Stream interceptors emit transactions and spans that represent the entire stream,
and not individual messages. For client streams, spans will be ended when the request
fails; when any of grpc.ClientStream.RecvMsg
, grpc.ClientStream.SendMsg
, or
grpc.ClientStream.Header
return with an error; or when grpc.ClientStream.RecvMsg
returns for a non-streaming server method.
module/apmhttprouter
editPackage apmhttprouter provides a low-level middleware handler for httprouter.
For each request, a transaction is stored in the request context, which can be obtained via
http.Request.Context()
in your handler.
import ( "github.com/julienschmidt/httprouter" "go.elastic.co/apm/module/apmhttprouter/v2" ) func main() { router := httprouter.New() const route = "/my/route" router.GET(route, apmhttprouter.Wrap(h, route)) ... }
httprouter does not provide a means of obtaining the matched route, hence the route must be passed into the wrapper.
Alternatively, use the apmhttprouter.Router
type, which wraps httprouter.Router
,
providing the same API and instrumenting added routes. To use this wrapper type, rewrite your use of httprouter.New
to apmhttprouter.New
; the returned type
is *apmhttprouter.Router
, and not *httprouter.Router
.
import "go.elastic.co/apm/module/apmhttprouter/v2" func main() { router := apmhttprouter.New() router.GET(route, h) ... }
module/apmnegroni
editPackage apmnegroni provides middleware for the negroni library.
For each request, a transaction is stored in the request context, which can be obtained via http.Request.Context in your handler.
import ( "net/http" "go.elastic.co/apm/module/apmnegroni/v2" ) func serverHandler(w http.ResponseWriter, req *http.Request) { ... } func main() { n := negroni.New() n.Use(apmnegroni.Middleware()) n.UseHandler(serverHandler) http.ListenAndServe(":8080", n) }
The apmnegroni handler will recover panics and send them to Elastic APM.
module/apmlambda
editPackage apmlambda intercepts requests to your AWS Lambda function invocations.
This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.
Importing the package is enough to report the function invocations.
import ( _ "go.elastic.co/apm/module/apmlambda/v2" )
We currently do not expose the transactions via context; when we do, it will be necessary to make a small change to your code to call apmlambda.Start instead of lambda.Start.
module/apmsql
editPackage apmsql provides a means of wrapping database/sql
drivers so that queries and other
executions are reported as spans within the current transaction.
To trace SQL queries, register drivers using apmsql.Register and obtain connections with apmsql.Open. The parameters are exactly the same as if you were to call sql.Register and sql.Open respectively.
As a convenience, we also provide packages which will automatically register popular drivers with apmsql.Register:
- module/apmsql/pq (github.com/lib/pq)
- module/apmsql/pgxv4 (github.com/jackc/pgx/v4/stdlib)
- module/apmsql/mysql (github.com/go-sql-driver/mysql)
- module/apmsql/sqlite3 (github.com/mattn/go-sqlite3)
- module/apmsql/sqlserver (github.com/microsoft/mssqldb)
import ( "go.elastic.co/apm/module/apmsql/v2" _ "go.elastic.co/apm/module/apmsql/v2/pq" _ "go.elastic.co/apm/module/apmsql/v2/sqlite3" ) func main() { db, err := apmsql.Open("postgres", "postgres://...") db, err := apmsql.Open("sqlite3", ":memory:") }
Spans will be created for queries and other statement executions if the context methods are used, and the context includes a transaction.
module/apmgopg
editPackage apmgopg provides a means of instrumenting go-pg database operations.
To trace go-pg
statements, call apmgopg.Instrument
with the database instance you plan on using and provide
a context that contains an apm transaction.
import ( "github.com/go-pg/pg" "go.elastic.co/apm/module/apmgopg/v2" ) func main() { db := pg.Connect(&pg.Options{}) apmgopg.Instrument(db) db.WithContext(ctx).Model(...) }
Spans will be created for queries and other statement executions if the context methods are used, and the context includes a transaction.
module/apmgopgv10
editPackage apmgopgv10 provides a means of instrumenting v10 of go-pg database operations.
To trace go-pg
statements, call apmgopgv10.Instrument
with the database instance you plan on using and provide
a context that contains an apm transaction.
import ( "github.com/go-pg/pg/v10" "go.elastic.co/apm/module/apmgopgv10/v2" ) func main() { db := pg.Connect(&pg.Options{}) apmgopg.Instrument(db) db.WithContext(ctx).Model(...) }
module/apmgorm
editPackage apmgorm provides a means of instrumenting GORM database operations.
To trace GORM
operations, import the appropriate apmgorm/dialects
package (instead of the
gorm/dialects
package), and use apmgorm.Open
(instead of gorm.Open
). The parameters are
exactly the same.
Once you have a *gorm.DB
from apmgorm.Open
, you can call apmgorm.WithContext
to
propagate a context containing a transaction to the operations:
import ( "go.elastic.co/apm/module/apmgorm/v2" _ "go.elastic.co/apm/module/apmgorm/v2/dialects/postgres" ) func main() { db, err := apmgorm.Open("postgres", "") ... db = apmgorm.WithContext(ctx, db) db.Find(...) // creates a "SELECT FROM <foo>" span }
module/apmgormv2
editPackage apmgormv2 provides a means of instrumenting GORM database operations.
To trace GORM
operations, import the appropriate apmgormv2/driver
package (instead of the
gorm.io/driver
package), use these dialects to gorm.Open
instead of gorm drivers.
Once you have a *gorm.DB
, you can call db.WithContext
to
propagate a context containing a transaction to the operations:
import ( "gorm.io/gorm" postgres "go.elastic.co/apm/module/apmgormv2/v2/driver/postgres" ) func main() { db, err := gorm.Open(postgres.Open("dsn"), &gorm.Config{}) ... db = db.WithContext(ctx) db.Find(...) // creates a "SELECT FROM <foo>" span }
module/apmgocql
editPackage apmgocql provides a means of instrumenting gocql so that queries are reported as spans within the current transaction.
To report gocql
queries, construct an apmgocql.Observer
and assign it to
the QueryObserver
and BatchObserver
fields of gocql.ClusterConfig
, or install it
into a specific gocql.Query
or gocql.Batch
via their Observer
methods.
Spans will be created for queries as long as they have context associated, and the context includes a transaction.
import ( "github.com/gocql/gocql" "go.elastic.co/apm/module/apmgocql/v2" ) func main() { observer := apmgocql.NewObserver() config := gocql.NewCluster("cassandra_host") config.QueryObserver = observer config.BatchObserver = observer session, err := config.CreateSession() ... err = session.Query("SELECT * FROM foo").WithContext(ctx).Exec() ... }
module/apmredigo
editPackage apmredigo provides a means of instrumenting Redigo so that Redis commands are reported as spans within the current transaction.
To report Redis commands, use the top-level Do
or DoWithTimeout
functions.
These functions have the same signature as the redis.Conn
equivalents apart from an
initial context.Context
parameter. If the context passed in contains a sampled
transaction, a span will be reported for the Redis command.
Another top-level function, Wrap
, is provided to wrap a redis.Conn
such that its
Do
and DoWithTimeout
methods call the above mentioned functions. Initially, the
wrapped connection will be associated with the background context; its WithContext
method may be used to obtain a shallow copy with another context. For example, in an
HTTP middleware you might bind a connection to the request context, which would
associate spans with the request’s APM transaction.
import ( "net/http" "github.com/gomodule/redigo/redis" "go.elastic.co/apm/module/apmredigo/v2" ) var redisPool *redis.Pool // initialized at program startup func handleRequest(w http.ResponseWriter, req *http.Request) { // Wrap and bind redis.Conn to request context. If the HTTP // server is instrumented with Elastic APM (e.g. with apmhttp), // Redis commands will be reported as spans within the request's // transaction. conn := apmredigo.Wrap(redisPool.Get()).WithContext(req.Context()) defer conn.Close() ... }
module/apmgoredis
editPackage apmgoredis provides a means of instrumenting go-redis/redis so that Redis commands are reported as spans within the current transaction.
To report Redis commands, use the top-level Wrap
function to wrap a
redis.Client
, redis.ClusterClient
, or redis.Ring
. Initially, the wrapped
client will be associated with the background context; its WithContext
method
may be used to obtain a shallow copy with another context. For example, in an
HTTP middleware you might bind a client to the request context, which would
associate spans with the request’s APM transaction.
import ( "net/http" "github.com/go-redis/redis" "go.elastic.co/apm/module/apmgoredis/v2" ) var redisClient *redis.Client // initialized at program startup func handleRequest(w http.ResponseWriter, req *http.Request) { // Wrap and bind redisClient to the request context. If the HTTP // server is instrumented with Elastic APM (e.g. with apmhttp), // Redis commands will be reported as spans within the request's // transaction. client := apmgoredis.Wrap(redisClient).WithContext(req.Context()) ... }
module/apmgoredisv8
editPackage apmgoredisv8 provides a means of instrumenting go-redis/redis for v8 so that Redis commands are reported as spans within the current transaction.
To report Redis commands, you can call AddHook(apmgoredis.NewHook())
from instance of redis.Client
, redis.ClusterClient
, or redis.Ring
.
import ( "github.com/go-redis/redis/v8" apmgoredis "go.elastic.co/apm/module/apmgoredisv8/v2" ) func main() { redisClient := redis.NewClient(&redis.Options{}) // Add apm hook to redisClient. // Redis commands will be reported as spans within the current transaction. redisClient.AddHook(apmgoredis.NewHook()) redisClient.Get(ctx, "key") }
module/apmrestful
editPackage apmrestful provides a go-restful filter for tracing requests, and capturing panics.
For each request, a transaction is stored in the request context, which can be obtained via
http.Request.Context()
in your handler.
import ( "github.com/emicklei/go-restful" "go.elastic.co/apm/module/apmrestful/v2" ) func init() { // Trace all requests to web services registered with the default container. restful.Filter(apmrestful.Filter()) } func main() { var ws restful.WebService ws.Path("/things").Consumes(restful.MIME_JSON, restful.MIME_XML).Produces(restful.MIME_JSON, restful.MIME_XML) ws.Route(ws.GET("/{id:[0-1]+}").To(func(req *restful.Request, resp *restful.Response) { // req.Request.Context() should be propagated to downstream operations such as database queries. })) ... }
module/apmchi
editPackage apmchi provides middleware for chi routers, for tracing requests and capturing panics.
For each request, a transaction is stored in the request context, which can be obtained via
http.Request.Context()
in your handler.
import ( "github.com/go-chi/chi" "go.elastic.co/apm/module/apmchi/v2" ) func main() { r := chi.NewRouter() r.Use(apmchi.Middleware()) r.Get("/route/{pattern}", routeHandler) ... }
module/apmlogrus
editPackage apmlogrus provides a logrus Hook implementation for sending error messages to Elastic APM, as well as a function for adding trace context fields to log records.
import ( "github.com/sirupsen/logrus" "go.elastic.co/apm/module/apmlogrus/v2" ) func init() { // apmlogrus.Hook will send "error", "panic", and "fatal" level log messages to Elastic APM. logrus.AddHook(&apmlogrus.Hook{}) } func handleRequest(w http.ResponseWriter, req *http.Request) { // apmlogrus.TraceContext extracts the transaction and span (if any) from the given context, // and returns logrus.Fields containing the trace, transaction, and span IDs. traceContextFields := apmlogrus.TraceContext(req.Context()) logrus.WithFields(traceContextFields).Debug("handling request") // Output: // {"level":"debug","msg":"handling request","time":"1970-01-01T00:00:00Z","trace.id":"67829ae467e896fb2b87ec2de50f6c0e","transaction.id":"67829ae467e896fb"} }
module/apmzap
editPackage apmzap provides a go.uber.org/zap/zapcore.Core implementation for sending error messages to Elastic APM, as well as a function for adding trace context fields to log records.
import ( "go.uber.org/zap" "go.elastic.co/apm/module/apmzap/v2" ) // apmzap.Core.WrapCore will wrap the core created by zap.NewExample // such that logs are also sent to the apmzap.Core. // // apmzap.Core will send "error", "panic", and "fatal" level log // messages to Elastic APM. var logger = zap.NewExample(zap.WrapCore((&apmzap.Core{}).WrapCore)) func handleRequest(w http.ResponseWriter, req *http.Request) { // apmzap.TraceContext extracts the transaction and span (if any) // from the given context, and returns zap.Fields containing the // trace, transaction, and span IDs. traceContextFields := apmzap.TraceContext(req.Context()) logger.With(traceContextFields...).Debug("handling request") // Output: // {"level":"debug","msg":"handling request","trace.id":"67829ae467e896fb2b87ec2de50f6c0e","transaction.id":"67829ae467e896fb"} }
module/apmslog
editPackage apmslog provides a slog Handler implementation for sending error messages to Elastic APM, as well as automatically attaching trace context fields to log records while using the context aware logging methods.
import ( "context" "log/slog" "go.elastic.co/apm/module/apmslog/v2" ) func ExampleHandler() { // Report slog "ERROR" level messages to Elastic APM using // apm.DefaultTracer() while utilizing some specific slog handler // to format logging messages apmHandler = apmslog.NewApmHandler( apmslog.WithHandler( slog.NewJSONHandler(os.Stderr, &slog.HandlerOptions{ Level: slog.LevelInfo, }), ), ) logger = slog.New(apmHandler) // while using slog context aware methods, any existing trace, // transaction, or span ID are added from the given context tx := apm.DefaultTracer().StartTransaction("name", "type") defer tx.End() ctx := apm.ContextWithTransaction(context.Background(), tx) span, ctx := apm.StartSpan(ctx, "name", "type") defer span.End() // log msg will have a trace, transaction, and a span attached logger.InfoContext(ctx, "I should have a trace, transaction, and span id attached!") // the log msg will be reported to apm logger.ErrorContext(ctx, "I want this to be reported, but have no error to attach") // the log msg with its error will be reported to apm logger.ErrorContext(ctx, "I will report this error to apm", "error", errors.New("new error")) // BOTH errors with the log msg will be reported to apm. [ error, err ] slog attribute keys are by default reported logger.ErrorContext(ctx, "I will report this error to apm", "error", errors.New("new error"), "err", errors.New("new err")) }
module/apmzerolog
editPackage apmzerolog provides an implementation of Zerolog's
LevelWriter
interface for sending error records to Elastic APM, as well as functions
for adding trace context and detailed error stack traces to log records.
import ( "net/http" "github.com/rs/zerolog" "go.elastic.co/apm/module/apmzerolog/v2" ) // apmzerolog.Writer will send log records with the level error or greater to Elastic APM. var logger = zerolog.New(zerolog.MultiLevelWriter(os.Stdout, &apmzerolog.Writer{})) func init() { // apmzerolog.MarshalErrorStack will extract stack traces from // errors produced by github.com/pkg/errors. The main difference // with github.com/rs/zerolog/pkgerrors.MarshalStack is that // the apmzerolog implementation records fully-qualified function // names, enabling errors reported to Elastic APM to be attributed // to the correct package. zerolog.ErrorStackMarshaler = apmzerolog.MarshalErrorStack } func traceLoggingMiddleware(h http.Handler) http.Handler { return http.HandlerFunc(func(w http.ResponseWriter, req *http.Request) { ctx := req.Context() logger := zerolog.Ctx(ctx).Hook(apmzerolog.TraceContextHook(ctx)) req = req.WithContext(logger.WithContext(ctx)) h.ServeHTTP(w, req) }) }
module/apmelasticsearch
editPackage apmelasticsearch provides a means of instrumenting the HTTP transport of elasticsearch clients, such as go-elasticsearch and olivere/elastic, so that elasticsearch requests are reported as spans within the current transaction.
To create spans for an elasticsearch request, wrap the client’s HTTP
transport using the WrapRoundTripper
function, and then associate the request
with a context containing a transaction.
import ( "net/http" "github.com/olivere/elastic" "go.elastic.co/apm/module/apmelasticsearch/v2" ) var client, _ = elastic.NewClient(elastic.SetHttpClient(&http.Client{ Transport: apmelasticsearch.WrapRoundTripper(http.DefaultTransport), })) func handleRequest(w http.ResponseWriter, req *http.Request) { result, err := client.Search("index").Query(elastic.NewMatchAllQuery()).Do(req.Context()) ... }
module/apmmongo
editPackage apmmongo provides a means of instrumenting the MongoDB Go Driver, so that MongoDB commands are reported as spans within the current transaction.
To create spans for MongoDB commands, pass in a CommandMonitor
created
with apmmongo.CommandMonitor
as an option when constructing a client, and then when
executing commands, pass in a context containing a transaction.
import ( "context" "net/http" "go.mongodb.org/mongo-driver/bson" "go.mongodb.org/mongo-driver/mongo" "go.mongodb.org/mongo-driver/mongo/options" "go.elastic.co/apm/module/apmmongo/v2" ) var client, _ = mongo.Connect( context.Background(), options.Client().SetMonitor(apmmongo.CommandMonitor()), ) func handleRequest(w http.ResponseWriter, req *http.Request) { collection := client.Database("db").Collection("coll") cur, err := collection.Find(req.Context(), bson.D{}) ... }
module/apmawssdkgo
editPackage apmawssdkgo provides a means of instrumenting the AWS SDK Go session object, so that AWS requests are reported as spans within the current transaction.
To create spans for AWS requests, you should wrap the session.Session
created
with session.NewSession
when constructing a client. When executing commands,
pass in a context containing a transaction.
The following services are supported:
- S3
- DynamoDB
- SQS
- SNS
Passing a session.Session
wrapped with apmawssdkgo.WrapSession
to these
services from the AWS SDK will report spans within the current transaction.
import ( "context" "net/http" "github.com/aws/aws-sdk-go/aws" "github.com/aws/aws-sdk-go/aws/session" "github.com/aws/aws-sdk-go/service/s3/s3manager" "go.elastic.co/apm/module/apmawssdkgo/v2" ) func main() { session := session.Must(session.NewSession()) session = apmawssdkgo.WrapSession(session) uploader := s3manager.NewUploader(session) s := &server{uploader} ... } func (s *server) handleRequest(w http.ResponseWriter, req *http.Request) { ctx := req.Context() out, err := s.uploader.UploadWithContext(ctx, &s3manager.UploadInput{ Bucket: aws.String("your-bucket"), Key: aws.String("your-key"), Body: bytes.NewBuffer([]byte("your-body")), }) ... }
module/apmazure
editPackage apmazure provides a means of instrumenting the Azure Pipeline Go pipeline object, so that Azure requests are reported as spans within the current transaction.
To create spans for Azure requests, you should create a new pipeline using the
relevant service’s NewPipeline
function, like azblob.NewPipeline
, then wrap
the pipeline.Pipeline
with apmazure.WrapPipeline
. The returned Pipeline
can be used as normal.
The following services are supported:
- Blob Storage
- Queue Storage
- File Storage
import ( "github.com/Azure/azure-storage-blob-go/azblob" "go.elastic.co/apm/module/apmazure/v2" ) func main() { p := azblob.NewPipeline(azblob.NewAnonymousCredential(), po) p = apmazure.WrapPipeline(p) u, err := url.Parse("https://my-account.blob.core.windows.net") serviceURL := azblob.NewServiceURL(*u, p) containerURL := serviceURL.NewContainerURL("mycontainer") blobURL := containerURL.NewBlobURL("readme.txt") // Use the blobURL to interact with Blob Storage ... }
module/apmpgx
editPackage apmpgx provides a means of instrumenting the
Pgx for v4.17+,
so that SQL queries are reported as spans within the current transaction.
Also this lib have extended support of pgx, such as COPY FROM queries and BATCH which have their own span types:
db.postgresql.copy
and db.postgresql.batch
accordingly.
To report pgx
queries, create pgx
connection, and then provide config to apmpgx.Instrument()
. If logger is presented in config,
then traces will be written to log. (It’s safe to use without logger)
Spans will be created for queries as long as they have context associated, and the context includes a transaction.
Example with pool:
import ( "github.com/jackc/pgx/v4/pgxpool" "go.elastic.co/apm/module/apmpgx/v2" ) func main() { c, err := pgxpool.ParseConfig("dsn_string") ... pool, err := pgxpool.ParseConfig("dsn") ... // set custom logger before instrumenting apmpgx.Instrument(pool.ConnConfig) ... }
Example without pool:
import ( "github.com/jackc/pgx/v4" "go.elastic.com/apm/module/apmpgx/v2" ) func main() { c, err := pgx.Connect(context.Background, "dsn_string") ... // set custom logger before instrumenting apmpgx.Instrument(c.Config()) ... }
