Hi,

I'm know this question had been asked before and would like to know with current version can
( Any other way to achieve )

1) Reports consolidate cpu or memory usage for hostgroup ?

2) Report showing available or unavailable Number of Core logical or physical cpu for hostgroup ?

Thanks
James T

Hi James,

You can get CPU or memory usage for hostgroup in the Metrics component ( Home > Details > Metrics ). However, not all plugins return data to the metrics component, so it is limited.

As far as a report showing available/unavailable cpu cores by hostgroup, I would recommend using host-group status page or creating a service group for those checks. You can schedule pages as pdf reports from the hamburger menu on the upper right.

Let me know if you have further questions.

Apologies for not making myself clear. Can we have 1 consolidate report for all hosts CPU or Memory usage rather then each host having their own Graph?

I am still not sure on the format of the report you would like to have. You you want to see a table cpu/memory values for all hosts, members of a hostgroup or you would like to see the average values for the hostgroup?

Example (if you had a "hostgroup" with 3 members - host1, host2, and host3)
host1 cpu = a
host2 cpu = b
host3 cpu = c
hostgroup cpu = (a + b + c) / 3

We do not have such a report. You could contact our sales team at [email protected], and request a quote for custom development. Having said that, I don't even know how this is going to work. Getting the average cpu/memory value for a specific timeperiod would be difficult as usually hostgroups are "dynamic" objects - members are often added to or removed from them. This is going to skew the results...

If you wanted to plot the cpu/memory metrics on a single graph, you could use the Graph Explorer's Multistacked Performance Graph functionality. You could add the cpu or memory checks (for all members of the hostgroup) to one graph, select the timeperiod, and schedule the page as a report. The graph can get very overcrowded if you had many members in the hostgroup. I am not sure if this is going to be a good solution for you.

Thanks, please close this post.
