Getting Started


These instructions assume your Icinga2 is installed on a RHEL/CentOS system.  You may need to modify slightly to work with other systems.


Prerequisites


Net-SNMP (http://www.net-snmp.org/)


Nagios plugins installed and located in /usr/lib64/nagios/plugins


Installing


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


Restart Icinga2:


sudo systemctl restart icinga2
