<DIV dir=ltr><STRONG><FONT face=Arial color=#000080 size=2>I had issues with
check_ping under MS Virtual Server. The plugin would routinely timeout. We
suspected it could be a clock drift issue because MS does not have VM Aditions
for *nix yet. I switched to check_icmp and things have been
good...</FONT></STRONG></DIV>

check_ping times<BR></FONT><BR></DIV>
<DIV>
<P><FONT size=2>I sporadically ( 1 or 2 times/day for 50 hosts) get check_ping
returing<BR>average response times of 500ms plus resulting in false
"critical"<BR>alerts from Nagios. E.G.<BR>PING CRITICAL - Packet loss =
0%, RTA = 535.87 ms<BR><BR>I'm running Suse 9.1 on VMWare ESX server. I DO
NOT believe vmware to<BR>be a factor because I also run smokeping on this
virtual machine. <BR>SmokePing sends 3 pings every 5 seconds to the same
hosts and never<BR>shows the 500ms+ latency that Nagios reports. During
the course of a<BR>typical day I get 80-100 of these "false alarms"<BR>I suspect
the problem is in the nagios daemon and how i have it<BR>configured. When
i run check_ping manually i can't reproduce the<BR>500ms+. Are there any
quick tests or diagnostics to help figure what's<BR>going
on?<BR><BR>Reg<BR><BR><BR>-------------------------------------------------------<BR>This
