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><br clear="all"><br><br>
