Graph data missing : DPM/MABS Server

[Lucien Karsten]

Hello Zabbix Fanatics,

I have a DPM Server running for our backup infrastructure, I am monitoring it with the Zabbix Agent 2 with Passive checks. The server has 1300 items because of all the discovery items detecting mounted volumes, that's how DPM works.

The issue I am having is that for 1, the zabbix agent crashes alot, every mornging I wake up and the service has crashed.

Second issue is i am missing immense graph data on the server.



Above we see the CPU utilization.

At first maybe I thought there was a resource issue, but to be honest the server is very calm, not only in CPU, but also in Memory usage and utilization. Same counts for the Zabbix server itself, no resource issues regarding utilization of some sort.

Is this an agent bottleneck what I see? Every other server has no issue with this, only the DPM server.

Only thing I can imagine it having a high disk i/o because of constant backup writing and reading, maybe max tcp connections? But tbh upload copy to azure isn't something it does the whole day, only at night.

I hope someone can help me figure this out, because I am out of idea's.

Hello everyone,

For the people with the same issue, it looks like I reached the bottleneck with the passive agent.

I solved this by using the active agent checks.

Thanks!
