vivid-planet / munin-php-apc Goto Github PK

I did this to make all the symlinks:

for i in files fragmentation hit_miss purge rates usage mem_size user_hit_miss user_entries user_rates; do sudo ln -s /path/to/php_apc_ /etc/munin/plugins/php_apc_$i; done

You can just add and remove the graphs from the for params as needed.

I was successfully able to setup php_apc_ even though I am running munin 2.0.25. At the moment I am only capturing usage data. Is it possible to define warning/critical thresholds for the 'used' and 'fragmented' monitors? It appears munin is using a new way of passing variables. I tried the following configuration - the env.url value is being passed but I do not see the other values reflected in the table below the graphs.

Thanks, Norbert

env.fragmented_critical 10485760

If purge rate exceeds 10%, it would be determined as warning.
My question is why purge so much cache is a problem?
It's about performance issue or something ?
