Linux config files

linux_config_files is an application intended to monitor a Linux distribution's configuration files via that distribution's configuration management tool/system. At this time, ONLY RPM-based (Fedora/RHEL) SYSTEMS ARE SUPPORTED utilizing the rpmconf tool. The linux_config_files application collects and graphs the total count of configuration files that are out of sync and graphs that number.

Fedora/RHEL: Rpmconf is a utility that analyzes rpm configuration files using the RPM Package Manager. Rpmconf reports when a new configuration file standard has been issued for an upgraded/downgraded piece of software. Typically, rpmconf is used to provide a diff of the current configuration file versus the new, standard configuration file. The administrator can then choose to install the new configuration file or keep the old one.

SNMP Extend

  1. Copy the python script, linux_config_files.py, to the desired host

    wget https://github.com/librenms/librenms-agent/raw/master/snmp/linux_config_files.py -O /etc/snmp/linux_config_files.py

  2. Make the script executable

    chmod +x /etc/snmp/linux_config_files.py

  3. Edit your snmpd.conf file and add:

    extend linux_config_files /etc/snmp/linux_config_files.py

  4. (Optional on an RPM-based distribution) Create a /etc/snmp/linux_config_files.json file and specify the following:

    {
    "pkg_system": "rpm",
    "pkg_tool_cmd": "/bin/rpmconf",
}
    Parameter Description Default Value
    pkg_system String designating the distribution name, "rpm"
    pkg_tool_cmd String path to the package tool binary "/sbin/rpmconf"

  5. Restart snmpd.

    sudo systemctl restart snmpd
