OS Updates

A small shell script that checks your system package manager for any available updates. Supports apt-get/pacman/yum/zypper package managers.

For pacman users automatically refreshing the database, it is recommended you use an alternative database location --dbpath=/var/lib/pacman/checkupdate

Agent or SNMP Extend

  1. Download the script onto the host.

    wget https://raw.githubusercontent.com/librenms/librenms-agent/master/snmp/osupdate -O /etc/snmp/osupdate

  2. Make the script executable.

    chmod +x /etc/snmp/osupdate

  3. Edit your snmpd.conf file, usually /etc/snmp/snmpd.conf, and add:

    extend osupdate /etc/snmp/osupdate

  4. Restart snmpd on your host.

    sudo systemctl restart snmpd

Debian/Ubuntu Apt

The apt-get depends on an updated package index. There are several ways to have your system run apt-get update automatically.

The easiest is to create /etc/apt/apt.conf.d/10periodic and pasting the following in it: 

APT::Periodic::Update-Package-Lists "1";

If you have apticron, cron-apt or apt-listchanges installed and configured, chances are that packages are already updated periodically .

LibreNMS discovers the application automatically, as described at the top of the page. If the discovery fails, do the steps under the SNMP Extend heading at the top of the page.

If this device has no agent, install the agent and copy the osupdate script to /usr/lib/check_mk_agent/local/

Then uncomment the line towards the top marked to be uncommented if using it as a agent.
