How to setup Disk Corrupt and Disk Available alerting on host group level ?

Hi @PrateekGupta

Disk Corrupt :  There are several factors that can identify a corrupted disk, for example, read errors, write errors, slow operation.
For this you have useful metrics such as:

- Disk read time                                  (builtin:host.disk.readTime )
- Disk read operations per second    (builtin:host.disk.readOps )
- Disk read bytes per second             (builtin:host.disk.bytesRead )
- Disk throughput read                    (builtin:host.disk.throughput.read)
- Disk write time                                (builtin:host.disk.writeTime)
- Disk write operations per second   (builtin:host.disk.writeOps)
- Disk write bytes per second            (builtin:host.disk.bytesWritten)
- Disk throughput write                   (builtin:host.disk.throughput.write)

Disk Available: I suggest measuring these metrics in Percentage
For this you have useful metrics such as:

- Disk available %                     (builtin:host.disk.free)
- Inodes available %                 (builtin:host.disk.inodesAvail)

Spoiler

*The marked metrics are the most used for this type of scenarios, however it depends on the need.

To apply these rules at the host group level:
1.- I think you can first create the rule from Data Explorer.

2.- Create a Metric Event (Using the code of Advanced mode) 

I hope it's helpful 💪
