I’m following the instructions below to filter metrics that are exported. Unfortunately i haven’t been able to filter metrics that start with cgroup.\* I just want some cgroup metrics to be exported (like cpu and memory for pods). Anyone know how you can filter them?

### Chart filtering

Netdata can filter metrics, to send only a subset of the collected metrics. You can use the configuration file

```auto
[prometheus:exporter] send charts matching = system.*

```

Hi @data-smith, it seems you’ve identified the relevant config option and know the charts you need to filter. Could you please elaborate on the specific issue you’re encountering? Did you try `send charts matching = cgroup*`?

I just tried cgroup\* and that works but cgroup.\* didn’t. I guess for regex you don’t need the period.  
Much better. Thanks!

It is not a regular expression but [Netdata’s simple pattern](https://learn.netdata.cloud/docs/developer-and-contributor-corner/libnetdata/simple-patterns).
