Hi folks,
I'm currently running IPVS 1.0.9 and ipvsadm 1.21 (compiled with popt
and IPVS 1.0.9). I plan to upgrade before the year is out. All my
services use LVS-NAT.
I'm writing a Nagios plugin to check details about an LVSed service and
return information to the monitoring host. I started trying to get the
statistics with SNMP, but I couldn't get the LVS-MIB to work (quickly).
Looking at /proc/net/ip_vs_stats, it seems to be overall stats for the
director, not per service. So I thought I'd parse the output of
'ipvsadm' to get the statistics.
I'm having a problem, however. The counters for InPkts, OutPkts, InBytes
and OutBytes are often returned by ipvsadm with a K, M, G, or T suffix
(e.g. numbers are in kilobytes, megabytes etc.). Unfortunately, this is
not granular enough for running checks every 5 minutes - the counters do
not update in that time, so it appears there is no traffic going through
for that service.
Can anyone suggest how I might get the stats values in bytes? Is there
something in /proc for IPVS 1.0.9 that I can use, or does a later
version of IPVS have more detailed stats somewhere?
Thanks,
Guy.
