Hi Everyone,<br>
<br>
I have been using nagios for 2 months now and it is really good. So
far, all plug-ins work well but recently the check_ping plugin has been
acting funny and giving wrong results. <br>
<br>
This is the OS info<br>
OS - Debian <br>
Nagios Version 2.9<br>
Problem = check_ping plugin reports alot of packet loss on our network
but when we use regular ping commands, it is not true. check_ping looks
like this in the command.cfg file<br>
<br>
# 'check_ping' command definition<br>
<span style="font-weight: bold;">define command{</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> command_name check_ping</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> command_line $USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 10</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> }</span><br>
<br>
This is an example of a service that uses check_ping<br>
<br>
<span style="font-weight: bold;">define service{</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> use servers</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> host_name bhslave@nkwanta</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> service_description PING</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> check_command check_ping!200.0,20%!600.0,60%</span><br style="font-weight: bold;">
<span style="font-weight: bold;"> }</span><br>
<br>
The problem is nagios will warn me of 28% packet loss to this host that
is 3 hops away from the monitoring system and the RTA will be about
60ms. It does this randomly. I will like to know how nagios computes
this info and how it determines this.<br>
<br>
Any help will be greatly appreciated.<br>
<br>
Regards,<br>
Alex Dehaini<br>
