I wouldn't rely on balancer_manager for a such monitoring because I've seen situations when it reported "Ok" status for workers that were down. As alternative method you can use sniffing Apache error_log file for the messages about disabled workers. You can OSSEC for that for example. On 6/14/07, Tom Haddon <tom@xxxxxxxxxxxxxxxxx> wrote:
Hi Folks, We've recently set up mod_proxy_balancer as a replacement for Pound, and I'm trying to work out the best way to monitor the load balancer to determine which servers are "in the loop" and which servers are "out of the loop". I'd ideally like to tie this in to Nagios so that I can get alerts if any of my servers gets taken out of the loop. At the moment I have the balancer-manager admin interface enabled for local connections only (i.e. from 127.0.0.1 on my apache server) and password protected, and have implemented something like the following for my Nagios check: command[check_beta_lb_1]=/usr/lib/nagios/plugins/check_http -H localhost -u /balancer-manager -a betaload:--password-- -s 'http://--dest-ip--:--dest-port--</a></td><td></td><td></td><td>1</td><td>Ok' This seems like a terrible hack, and I'm wondering if there's a better way to do this.
