Monitoring cluster resources

[franconovik]

I have a proxmox cluster with 3 nodes and I am wondering if I can use PRTG software to monitor
the cluster resources as disks, network and VMs to prenvent failure ?
I mean, PRTG can use snmp, proxmox supports snmp or something else so I can monitor cluster resources ?

Thanks a lot.

Well, PVE does not know anything about SNMP (or the other way around). But this is Debian, so yes, you can utilize SNMP.

or something else so I can monitor cluster resources ?

While primarily being a Zabbix (https://www.zabbix.com/la/integrations/proxmox) user - and Zabbix works well! - I found a gem somewhere else: https://grafana.com/grafana/dashboards/19119-proxmox-ve-cluster-flux/

My Grafana/Influx-setup followed a random "InfluxDB and Grafana and Proxmox PVE" instruction found at a random website. For this approach you do not need to install additional software on the host. Most other solutions need a daemon of any kind to gather information. For Influx it is integrated by default: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#external_metric_server

In my constrained recognition Zabbix is both more flexible and more complex.

LibreNMS (https://www.librenms.org/) was the easiest experience for me: just install SNMPd and a lot of metrics are autodiscovered - but only generic "Linux", nothing really PVE-specific - so it is not optimal.

For all approaches you need a place to run that software. This may be a VM - but monitoring a virtualization hardware makes more sense by running the monitoring software on independent hardware, off-cluster.

From your reply I am understanding that proxmox ve supports the following products :
Zabbix

Proxmox VE Cluster [Flux]​

librenms

Am I right ?

There is no official/specific support for any monitoring suite.

If you follow my first two links you'll see what is possible with the respective tool when used for/with PVE. The implementation of such a monitoring suite is out-of-scope for PVE alone, as it is a separate and independent tool.

The only pre-prepared and in PVE integrated aspect is this: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#external_metric_server.
