Plugin to monitor performance of eaccelerator module for PHP.
|
|
|
|
To use:
|
|
1. Copy script to munin plugins folder
|
|
2. Symbolically link to eacc_memory and eacc_cached
|
|
* eacc_memory shows memory usage
|
|
* eacc_cached shows number of scripts cached and discarded
|
|
3. Set configuration options in munin config file as follows
|
|
[eacc_*]
|
|
env.auth_user username
|
|
env.auth_pwd password
|
|
env_cpanel url_of_stats.php
|
|
4. Copy stats.php into the eacc control panel folder and set $user/$pw to match auth_user/auth_pwd
|
|
* Ideally, these should be the same values as set in control.php
|
|
5. Run `munin-run eacc_memory` and `munin-run eacc_cached` to make sure scripts are running correctly, you should see non-zero values
|
|
6. Restart munin-node
|
