# Enable diagnostics
|
|
|
|
You can set up the `grafana-server` process to enable certain diagnostics when it starts. This can be helpful
|
|
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 arguments `-profile` to enable profiling and `-profile-port` to override
|
|
the default HTTP port (`6060`) where the `pprof` debugging endpoints are available, for example:
|
|
|
|
```bash
|
|
./grafana-server -profile -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:
|
|
|
|
```bash
|
|
export GF_DIAGNOSTICS_PROFILING_ENABLED=true
|
|
export GF_DIAGNOSTICS_PROFILING_PORT=8080
|
|
```
|
|
|
|
Refer to [Go command pprof](https://golang.org/cmd/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:
|
|
|
|
```bash
|
|
./grafana-server -tracing -tracing-file=/tmp/trace.out
|
|
```
|
|
|
|
You can configure or override profiling settings using environment variables:
|
|
|
|
```bash
|
|
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):
|
|
|
|
```bash
|
|
go tool trace <trace file>
|
|
2019/11/24 22:20:42 Parsing trace...
|
|
2019/11/24 22:20:42 Splitting trace...
|
|
2019/11/24 22:20:42 Opening browser. Trace viewer is listening on http://127.0.0.1:39735
|
|
```
|
|
|
|
See [Go command trace](https://golang.org/cmd/trace/) for more information about how to analyze trace files. |
