Monitor updates on Gentoo

[acalvo]

Having Zabbix to warn you when a server needs to be updated is a must-have for any sysadmin.

So, here's what I've come with:

UserParameter=gentoo.security,glsa-check -t all 2>/dev/null | wc -l
UserParameter=gentoo.updates,emerge -tpvuD system | grep ebuild|wc -l
UserParameter=gentoo.portage,emerge --info| grep 'Timestamp of tree' | sed -e s/'Timestamp of tree':// -e 's/\n//' | xargs -I {} date --date={} +%s
UserParameter=gentoo.config,find /etc/ -name '._cfg*' 2>/dev/null|wc -l

(and some people in this forum!)

As I noted in another post you might want to put these into a cron job and push to the Zabbix server using zabbix_sender. If the download takes a while then the check will timeout and you won't have your data. You could write a trigger which checks to see if you don't have data for that value for a period double what your check interval is.

This is right for Red Hat or CentOS.
However, Gentoo uses an specific command to update it's local repository, so now download takes place during the invocation of the remote command.
