<p>ToyKeeper: linked to actual upstream code, instead of an outdated copy</p> <hr /> <div>Monitoring /proc/user_beancounters to see if any containers are hitting limits is an important part of<br /> managing an OpenVZ installation. Containers that are hitting key limits can have applications malfunction in strange ways that can only be diagnosed by realising that it is a UBC configuration issue.<br /> <br /> A small script, '''failcnt.py''', can run via cron on the host node and watch all VEs for failures. It emails the host node admin a failure summary.<br /> <br /> To get the latest version using bzr, run:<br /> <br /> bzr branch lp:tkmisc<br /> cd tkmisc/vz_failcnt<br /> <br /> It can also be downloaded from:<br /> <br /> https://launchpad.net/tkmisc/<br /> or<br /> http://bazaar.launchpad.net/~toykeeper/tkmisc/trunk/files<br /> <br /> Then, to install it, create '''/etc/cron.hourly/vz-failcnt''', containing:<br /> <br /> #!/bin/sh<br /> /path/to/tkmisc/vz_failcnt/failcnt.py<br /> <br /> This script, when run periodically (using cron) will detect changes in the failcnt field of /proc/user_beancounters<br /> <br /> <br /> [[Category: Troubleshooting]]</div>
