[Xymon] Alerts based on rrd graphs

[Jeremy Laidman]

Yes.  I watch NTP offsets from ntpstat.rrd with the following in
analysis.cfg:

HOST=%^(host1|host2)
        # alert if NTP offset exceeds 10ms
        DS ntp ntpstat.rrd:offsetms >10 COLOR=red "TEXT=NTP offset &Vms is
higher than &Ums"
        DS ntp ntpstat.rrd:offsetms >5 COLOR=yellow "TEXT=NTP offset &Vms
is higher than &Ums"
        DS ntp ntpstat.rrd:offsetms <=5 COLOR=green "TEXT=NTP offset &Vms
is within +/-&Ums"
        DS ntp ntpstat.rrd:offsetms <-10 COLOR=red "TEXT=NTP offset &Vms is
lower than &Lms"
        DS ntp ntpstat.rrd:offsetms <-5 COLOR=yellow "TEXT=NTP offset &Vms
is lower than &Lms"

Also, I do a similar thing for DNS latency, where the graphs are
automatically generated when I add a "dns" test configuration to hosts.cfg:

        # alert if lookups take too long (200ms or 50ms)
        DS dns tcp.dns.rrd:sec >0.05 COLOR=yellow "TEXT=Response time &V
exceeds &U seconds"
        DS dns tcp.dns.rrd:sec >0.2 COLOR=red "TEXT=Response time &V
exceeds &U seconds"

These go into my SLA-type reports to management.

Cheers
Jeremy
