This plugin can be download here: hmib-v1.4-2.tgz
This plugin was designed with polling scalability in mind in addition to providing a dashboard for common device metrics. It is designed to offload the polling of slow devices such as disks to a sub process. In addition, the polling for different objects can be staggered at different levels thus reducing load on the poller.
A great example is disk utilization. Generally, disk utilization does not change too often. With this plugin, you can have your Cacti plotting data at 1 minute intervals, but only collect disk utilization from the host once ever 30 minutes, or an hour. With very busy Filers and Windows hosts, the Host Resource Mib polling can be slow, thus limiting the scalability of your systems. If you have this problem, hmib is for you.

Installation is similar to other plugins.
- First you install and enable from Plugin Management.
- Then you must enable collection from Console→Settings→Host Mib.
- Here you specify things such as
- How many concurrent processes to poll with,
- The frequency of polling, and more importantly,
- The Graph Templates and Data Queries to Graph Automation. (screen shot provided)
- Once these steps are completed, you must import a Host Template for Summary Information and install the Resource XML file for the Data Queries
- After this, there are replacement script that you must place in the scripts directory in Cacti for the Standard Host Resources MIB Templates in Cacti. These are key.
- Once you have installed the template, you may proceed to complete the Dropdowns under Console→Settings→Host Mib for Data Queries and Graph Templates.
- Next, you need to observe Host Mib inventory your Cacti devices and find those that support the Host Resources Mib. The plugin will find each one of these and start to poll it's data.
- Lastly, you must identify the host OS Types for each installed system. The identification process is much like that of MacTrack where you scan the inventory, and then use either regular expression matches or SQL Where clauses to narrow the sysDesc and sysObjectID to an OS Name and version.
After you have done all this, just sit back and enjoy. You may tune the number of concurrent processes until such time as you are happy with the load introduced by this plugin.
