icmpping failing on slow links

[demigh0d]

Not sure if this has been covered before....

I am pinging a bunch of servers over a VPN connection and have been having problems using icmpping. There are many times that the latency on the VPN will go way up and fping times out before the response is received causing a erroneous failure alert.

Evidently the default timeout in fping is 500ms.

You can change this by editing the source file

~/src/zabbix_server/pinger/pinger.c

and change

zbx_snprintf(str,sizeof(str),"cat /tmp/zabbix_server_%li.pinger | %s -e 2>/dev/null",

to something like

zbx_snprintf(str,sizeof(str),"cat /tmp/zabbix_server_%li.pinger | %s -t 5000 -e 2>/dev/null",

'-t 5000' increased the timeout to 5 seconds and completely eliminated the bogus alerts I was getting.

Maybe this should be added as a configurable parameter in Zabbix?

So are you having a problem or suggesting a fix?

I was having a problem, figured out how to fix it and thought I'd post it for anyone else having the same problem.

Ahh! I was a little lost thanks for the clarification. It's a complicated problem you were having too.
