Work monitoring ok, add 2 host ( switch cisco and host docker )
For some reason appear this message:
As soon as you add your Checkmk server to the monitoring, a graph showing the history of your host problems will appear here. Please refer to the [Checkmk user guide](https://docs.checkmk.com/2.1.0/en/dashboards.html#host_problems)for more details.
The message you get means, that the system where CMK is running on must be monitored with an agent. In your case this will be the system inside the container.
Steps to get rid of this message:
setup monitoring for the Docker host
deploy the Docker plugin inside the agent of the Docker host
create a host object for your CMK container inside the system - follow here the manual about “Monitoring Docker”
One question - why do you use an old version of CheckMK that is not supported anymore?
Normally you calculate between 20 and 40 services per normal host. (old free edition 25 hosts with 30 services → 750 services for the free tier in the new cloud edition)
A docker container without agent for instance has only 8 or 9 services.
Inside my home environment i have around 600 services with 40 host objects.
The most services here are my two Proxmox hosts.
Appear same text:
As soon as you add your Checkmk server to the monitoring, a graph showing the history of your host problems will appear here. Please also be aware that this message might appear as a result of a filtered dashboard. This dashlet currently only supports filtering for sites.Please refer to the Checkmk user guide for more details.
The screenshot shows only the container host, but now you have to deploy the Docker plugin on this host to also monitor the container itself. As your CheckMK runs inside a container, this data is needed.
To monitor docker on the host as well as any containers you’ll need to go through the guide posted previously as there’s a few things you have to do to get it working properly
