Advanced CI Selection and Filtering in Metric Rules

[david_taggart]

I've a use case that requires me to setup multiple metrics rules on one server. I'll have to monitor the /home directory with one set of thresholds, but I also have to monitor the /opt directory with a separate set of thresholds.

I'm unable as of yet to create an ACC-M Metric Rule that selects only certain File Systems that are related to Linux Servers. I am able to select appropriate servers by host name with the selection criteria [Configuration Item > Name]. However I am attempting to select only one or several File Systems contained on Linux Servers. I've attempted this with numerous selection methods:

[Configuration Item > File System > Mount Point ]
[Configuration Item > Configuration item > Linux Server > Asset > Configuration Item > File System > Mount point ]
etc.

How do I build a metric rule that selects only specific File Systems for Metric Alerts based on specific Linux Server names? I am able to use the CMDB Query builder to achieve advanced selection criteria, how do I replicate this using Metrics Rules?

I managed to find the answer to my own question. When creating a new Metric Rule for a Linux Server, some CI Resource Hardware metrics will give enough granularity to selectively target individual File System Mount Points.

While exploring available Metrics in Insights Explorer, I discovered a KPI term "disk_usage_used_percentage" would attach to individual mount points, such as root.home . When creating a Metric Rule for a Linux Server CI, searching for all metrics containing "disk_usage_used_percentage" reveals a number of different choices, each one giving a mount point in parentheses, EG: (root.home).
