It's called rrdbotd: http://memberwebs.com/stef/software/rrdbot/ It lets you poll a URL that looks like: snmp://public@example.com/jailInOctets?jailHost=jail.example.com See 'TABLE QUERIES' here: http://memberwebs.com/stef/software/rrdbot/rrdbot.conf.5.html http://memberwebs.com/stef/software/rrdbot/rrdbot-get.1.html In addition rrdbotd can do crazy stuff like track the same jail as it moves across multiple machines. See 'MULTIPLE AGENTS'. We use quick failover migration of jails. Cheers, Stef Walter
