Hi,
I am trying to deploy distributed poller in scenario where we already have master deployed manually on RHEL. Poller is deployed as docker container
I have Redis component, rrdcached (without nfs), and mysql available via network. Everything seem to run fine, however for some reason poller recieves sigterm each night at 2:35 after daily cron job. Running this job manually wont reproduce the issue. I am stuck what could be killing it.
I am running containers on RHEL with podman as docker runtime. I run two containers similar to this docker-librenms/docker-compose-distributed-poller.yml at master · setiseta/docker-librenms · GitHub
- librenms
- librenms-dispatcher (sidecar)
./validate result from dispatcher
