check_icmp failure "handle_random_icmp" message

[wneville]

Hello,

I wanted to inquire about behavior I am seeing with check_icmp plugin version 2.4.5. This week a hypervisor admin reached out telling me he is receiving alerts when his hosts are up. I caught one of the hosts that nagios was seeing as 'down' and grabbed a verbose response of the check_icmp output.

The command is:

Code: Select all

./check_icmp -H $HOSTADDRESS -w 3000,80% -c 5000,100% -v

In the verbose output, I see a message that I can't find much info on via the web:

Code: Select all

There are 30-40 lines of this handle_random_icmp message and I am not sure why. Is this an issue with my network or is it something related to the behavior of the plugin?

wneville,

This reads like there was a timeout waiting for response, mostly due to the message returned in the middle of the handle_random_icmp calls:

Code: Select all

Packet is no response to a packet we sent

If you just try to ping the host in question from the XI server, do you get a response?

Best Regards,

Turns out there was a problem in the network gear, thank you very much for your response you can lock this up
