SMNP of KVMs

[informant]

Hi, a little question. Do VMs in KVM have a SMNP API for monitoring it or does proxmox have a api to smnp the VMs? We would monitoring for exsample bandwidth...

best regards

Your VM itself needs the SNMP services installed and configured.

hi, we would not install in a vm a client, we would read information on node of all vm´s!

You asked about monitoring the VMs themselves.

Hi, no for api or snmp conenction point on host/node for vm´s. we can not install software on a customer maschine, we can only isntall on node.

do you have here a idea? regards

You could use Nagios or even better Icinga2 with Icingaweb2 as monitoring and then install / configure the pve-monitor plugin.
The plugin is using the proxmox api to get some basic informations about the VMs (KVM and OpenVZ) and also the configured storage of proxmox.

hi rene,

can we read with this plugin network traffic of vm´s? we would only read the bandwidth traffic.

No, that is not possible with the that plugin. Check the wiki for features.

But each VM is getting in a bridged setup its own tap device (e.g. tap100i0 where 100 is the VM ID) which can be monitored with Nagios / Icinga2 plugins.
For example check_ifutil.pl could do that for each network device you configure in the monitoring setup. Maybe there are also some other and better bandwidth plugins out there.
