I've enabled collectd on the router for data collection but once I've enabled and started the service, it seems to crash some time afterwards (sometimes it's hours after starting, other times it's minutes after starting the service).
This is the message logged when collectd exits:
Sat Sep 1 13:25:32 2018 daemon.info collectd: dns plugin: pcap_loop exited with status -1.
It's always the DNS plugin that causes this. Once the dns plugin exits, the rest of my collectd config stops working (so data stops being fed into InfluxDB for example) and the only way to fix it is to restart the collectd service (until the next time the DNS plugin stops working).
I'm using Davidc502's r7829-42dc0e2594 build on a WRT3200ACM.
And this is what my DNS plugin config is currently set to:
<Plugin dns> Interface any IgnoreSource "127.0.0.1" </Plugin>
