Sending mail alert on proxmox node disconnection.

[Franck Martinière]

Hello everyone,

I am new to Proxmox.
I have configured one cluster with two nodes and a DRBD disk.

Everythings work well : if I switch off a node, all VM are started on the other node.

Now I am looking how to send alert email on node disconnection. I haven't seen any documentation on internet.
Postfix is well setup I can send mail by command line : echo "test email" | mail -s "mail title" f.martiniere@environnement-sa.com

When I switch off a node I don't see any event in /var/log/mail.log.

Is someone can help me ?

Thank's in advance.
Franck

Hi Frank,
not realy an help - I do this with my icinga monitoring box (nagios fork).
But you can create an cronjob which control the status like

*/5 * * * * if [[ `pvecm nodes | egrep -v "  M  "\|"Node  Sts   Inc   Joined"` ]]; then echo "Node failed"; fi

(instead echo your mail-process)
This checks every 5 minutes if an nodes in the cluster is not flaged as M(ember) - not tested

Thank's Udo,

I have done something like that. I check the corosync.log file and then generate a mail alert.
But I thought that there is other solutions.

Franck.
