Dual-homed clients
Folks
I have some devices with multiple IP addresses that I want to monitor. Actually, not quite true - we actually have two paths with different static NAT, so each device can be contacted on either one of two IP addresses. As far as the Xymon server is concerned, there are two IP addresses for the one device.
My problem is, what's the best day for me to set this up in Xymon. I want to know if a service goes down on either path.
At present, I simply list each IP address with a hostname suffix, like these entries for "host147":
192.168.100.47 host147-a.example.com # ping smtp 192.168.200.47 host147-b.example.com # ping smtp
Is this the best I can do?
Cheers Jeremy
There's the 'conn' tag in hosts.cfg:
conn={best,|worst,}IP1[,IP2...] This adds additional IP-adresses that are pinged during the normal "conn" test. So the normal "conn" test must be enabled (the default) before this tag has any effect. The IP-adresses listed here are pinged in addition to the main IP-address.
When multiple IP\u2019s are pinged, you can choose if ALL
IP\u2019s must respond (the "worst" method), or AT LEAST one IP must respond (the "best" setting). All of the IP\u2019s are reported in a single "conn" status, whose color is determined from the result of pinging the IP\u2019s and the best/worst setting. The default method is "best" - so it will report green if just one of the IP\u2019s respond to ping.
Thanks, Larry Barber
