Hello @bluepuma77 and welcome into our community, This (cgroup_ram_in_use) topic may give you some insights about this alert.
TTBOMK you have two options:
- You either relax the threshold (by editing their configuration, conf-file: health.d/cgroups.conf) of the “warn” state for this alert. This will just hide the “issue”, so I don’t advise you to stick with this action.
- Set greater limits for the containers in question. Netdata informs you that these containers are running near the edge of their limits. Note here: If none limit is set; defaults apply by Docker but this shouldn’t be a case for all of your containers/workloads. Different containers, different demands.
I would suggest you to visit also the following topic:
Think about it and let us know about your situation
We are running prometheus/grafana but we can’t see RAM issues there.
Not so sure that they have predefined alerts for this resource.
