The hmib plugin is designed to collect SNMP information from Cacti Devices that support the SNMP Host Resources Mib structure. This SNMP information includes performance metrics like:
- CPU utilization,
- Running processes,
- Running applications,
- Physical and Virtual Memory utilization,
- Hardware details,
- Device details,
- Storage details,
- Installed software
This Host Mib information in then grouped into a series of Dashboards for Cacti Administrators to be able to view the status of their Devices. When installed Cacti will automatically discover your Cacti Devices that support the Host Resources MIB and add them to hmib. Once there, you can classify each of the discovered Devices operating system, and when that step is completed properly, the Cacti 'hmib' tab will classify system usage by Operating System.
The hmib plugin also includes several Graph Templates that allow you to track application memory and cpu utilization accross you environment as well as several other Cacti Graphs.
A few of these Cacti Graph Templates include script files that will allow Cacti to leverage the HMIB data for graphing instead of directly accessing the Cacti Devices for that information. This appoach leads to reduce Cacti polling times due to the elimination of latency obtaining the information.
Just like any other Cacti plugin, untar the package to the Cacti plugins directory, rename the directory to 'hmib', and then from Cacti's Plugin Management interface, Install and Enable the pluign.
Once you have installed the hmib plugin, you need to install it's Device Template, and then in addition, you must copy the script server script files to Cacti's scripts directory. Those files are located in the plugins templates/scripts directory. In addition, you should copy the script server resource files to Cacti's resource/script_server directory. Once there, graphing for Cacti's build in Host Resources Mib objects will come from the hmib plugin. Make backups of all files replaced, just in case you decide to remove the plugin at a later date.
Once everything is in place, you need to goto Cacti's Settings page and locate the 'Host MIB' tab and complete the hmib's setup. From there, you can set collections frequencies and levels of parallelism. You can also turn on the automation of Cacti Devices and Graphs as well. The hmib plugin also monitors application usage over time.
