Since a few hours the fw_conntrack plugin in munin gives always timeout error.

enter image description here

It looks like the timeout is just because it took too much time to process, as it had happened a few times before in the graph. Is it normal that this plugin take more than 10 seconds to finish? There is a Varnish which proxies http request to a nginx.

In a test:

jcisio@cecile:~$ time sudo cat /proc/net/nf_conntrack | wc -l
64218

real    0m13.165s
user    0m0.008s
sys 0m13.129s

It takes 13 seconds just to count the number of lines in this file. So munin could not do better. I have to increase the timeout limit.

How do you increase the timeout limit? Your answer would be more useful if you added that. –  Ariel 2 days ago
