## `customcmd` collector
|
|
|
|
```json
|
|
"customcmd": {
|
|
"exclude_metrics": [
|
|
"mymetric"
|
|
],
|
|
"files" : [
|
|
"/var/run/myapp.metrics"
|
|
],
|
|
"commands" : [
|
|
"/usr/local/bin/getmetrics.pl"
|
|
]
|
|
}
|
|
```
|
|
|

The `customcmd` collector reads data from files and the output of executed commands. The files and commands can output multiple metrics (separated by newline) but the have to be in the [InfluxDB line protocol](https://docs.influxdata.com/influxdb/cloud/reference/syntax/line-protocol/). If a metric is not parsable, it is skipped. If a metric is not required, it can be excluded from forwarding it to the sink.
