These instructions assume your Icinga2 is installed on a RHEL/CentOS system. You may need to modify slightly to work with other systems.
Nagios plugins installed and located in /usr/lib64/nagios/plugins
Download and install Net-SNMP. If you choose to build from source use the following lines:
./configure --with-perl-modules --with-mibdirs --enable-shared make make test make install
Copy check_aruba_ap into your plugin directory and give it executable writes:
sudo cp ./check_aruba_ap /usr/lib64/nagios/plugins/ chmod a+x /usr/lib64/nagios/plugins/check_aruba_ap
Copy aruba-ap.conf into plugins-contrib.d folder:
sudo cp ./aruba-ap.conf /usr/share/icinga2/include/plugins-contrib.d/
Append services-aruba-ap.conf to the end of your Icinga2 services.conf:
cat ./services-aruba-ap.conf >> /etc/icinga2/conf.d/services.conf
This script writes to the /tmp folder and needs to be added to sudoers for the username icinga.
If your installation is running on a different username, change it before copying the file:
icinga ALL = NOPASSWD: ICINGA2 to: ALL = NOPASSWD: ICINGA2
Copy sudoer file to proper place and give minimal permissions:
sudo cp ./icinga-sudoer /etc/sudoers.d/icinga sudo chmod 0440 /etc/sudoers.d/icinga
Extract Aruba MIB files:
sudo tar -xzvf ./aruba-mibs.tgz /usr/share/snmp/mibs/
Set proper MIB folder permissions:
sudo chown -R root:icinga /usr/share/snmp/mibs sudo chmod -R ug+rw /usr/share/snmp/mibs
Restore SELINUX permissions:
sudo restorecon -R -v /usr/lib64/nagios/plugins/ sudo restorecon -R -v /usr/share/snmp/mibs
If using Grafana, import JSON Dashboard (Graphite or InfluxDB) file and add graph dashboard information into module making sure to name the Dashboard aruba-controller:
sudo cat aruba-controller-graphs.ini >> /etc/icingaweb2/modules/grafana/graphs.ini
sudo systemctl restart icinga2
