I'm trying to send logs to the APM server using the uber zap logging library.
I've tried their instrumentation module (https://www.elastic.co/guide/en/apm/agent/go/1.x/builtin-modules.html#builtin-modules-apmzap) to do so but it's not working for me:
The transactions are not being sent to the APM server.
envs:
ELASTIC_APM_LOG_FILE=stderr=stderr
ELASTIC_APM_LOG_LEVEL=debug
ELASTIC_APM_SERVICE_NAME=service-name
ELASTIC_APM_SERVER_URL=http://localhost:8200
import (
"go.uber.org/zap"
"go.elastic.co/apm/module/apmzap"
)
// 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")
logger.With(traceContextFields...).Error("handling error")
}
