Service packet loss problem


#1

Hello, I’m running nagios 3.0.5 on Gentoo Linux and I have some question about configuration. I have approximatelly 100 hosts and I have ping service.

Questions:

  1. Where to set up number of packets during each check and how many is the ideal value for service check ?
  2. I have requlary reported packet loss of 16% of all my hosts, I check it manualy with ping, and it’s ok, view my screenshot ???

By default the number of packets are set to 5. Anyhow, you can change that to whatever youwish in check_ping command definition by adding the -p switch.
Try to run the check_ping plugin from the terminal:
/path/to/check_plugin --help
and it will show you all of the options. Try to execute it from the terminal then with the regular host and see what response do you get.

5 is ok to determine the ping reachability of the host.

If you have continuos packet loss then it could be related to your nagios server and it’s overload or heavy network traffic.
