Error message: No data from “clone” host with special agent
Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)
Hello,
I think a picture might help more with trying to understand what I’ve done in the past with VMWare and am not trying to do with Proxmox.
Due to volume of Checks, I had to go with distributed monitoring, where Site A handles core hosts and other sites are a grouping of VMs.
It is my understanding that for piggyback to work, both the host providing piggyback and the host that the piggyback data pertains to must be in the same site.
My issue is that similar to the illustration a PVE can provide data for hosts on different sites, given different classification, in this example Test/Prod, while it itself being core should be handled by the main site A.
With VMWare we had to solve this and found that we could just duplicate the host with a suffix (site_C for example) and that would work. We’d simply just have that “clone” only ever be configured with the agent.
With the proxmox special agent this simply doesn’t work. Could it be that the agent is more rudimentary? I also had to add the Proxmox host in /etc/hosts before the connection even worked.
The piggyback data does get generated, even on the clone host, but it just doesn’t work for the host itself. Re-running the checks will say that the Check is OK, but that there is no data.
Any ideas?
