Configure tracing to troubleshoot Grafana
You can set up the grafana-server
process to enable certain diagnostics when it starts. This can be useful
when investigating certain performance problems. It’s not recommended to have these enabled by default.
Turn on profiling
The grafana-server
can be started with the command-line option -profile
to enable profiling, -profile-addr
to override the default HTTP address (localhost
), and
-profile-port
to override the default HTTP port (6060
) where the pprof
debugging endpoints are available. For example:
./grafana server -profile -profile-addr=0.0.0.0 -profile-port=8080
Note that pprof
debugging endpoints are served on a different port than the Grafana HTTP server.
You can configure or override profiling settings using environment variables:
export GF_DIAGNOSTICS_PROFILING_ENABLED=true
export GF_DIAGNOSTICS_PROFILING_ADDR=0.0.0.0
export GF_DIAGNOSTICS_PROFILING_PORT=8080
Refer to Go command pprof for more information about how to collect and analyze profiling data.
Use tracing
The grafana-server
can be started with the arguments -tracing
to enable tracing and -tracing-file
to override the default trace file (trace.out
) where trace result is written to. For example:
./grafana server -tracing -tracing-file=/tmp/trace.out
You can configure or override profiling settings using environment variables:
export GF_DIAGNOSTICS_TRACING_ENABLED=true
export GF_DIAGNOSTICS_TRACING_FILE=/tmp/trace.out
View the trace in a web browser (Go required to be installed):
go tool trace <trace file>
