HP Cluster Management Utility 7.3 supportability

[HL-eng]

We are planning to run our HPC on

2 x Head nodes -  Proliant DL 360 Gen 9 and

Multiple Compute Nodes - HP Apollo 6000 chassis with HP Proliant XL 230 blade servers.

Questions:

1) Does HP CMU supports RHEL 7.2?

2) What are the metrics which HP CMU monitors: - CPU, memory , etc?

Hi,

Is this a HP internal cluster or a customer cluster?

RHEL7.2 support is available on CMU v7.3.2 (you need to install relevant patches as well). 
So, if you are using CMU v7.3 then you need to upgrade to CMU v7.3.2.

By default CMU implements monitoring of metrics like cpuload, memory_used, process_memory, page_cache, buffer_cache disk_write/read, ethX_MB/s_rx/tx etc.
You can check the default metrics in "/opt/cmu/etc/ActionAndAlertsFile.txt" file.

You can even customize this file to implement your own metrics. CMU also supports use of collectl tool for gathering monitoring data.
Please refer to section "6.5 Customizing HPE Insight CMU monitoring, alerting, and reactions" in CMUv7.3.2 user guide for more details on this.

Thanks,
Alok
