Group Count

[hupp]

Hi,

is it possible to do some group count like:
- total host in group
- available host in group
- hosts in maintenance in that group

greeting

This is an old post... But I've been looking for this as well.

I need to graph how many hosts are in a group. So far I've had no luck trying to figure it out, or using similar examples i've searched for. I have yet to see anything specific to creating an item that will count hosts in a group.

Please help!

Thank you...

I'm thinking about 12 Aggregate checks and "agent.ping" as "item.key"

Do you mind to try?

This seems to have worked! I suppose this way it counts devices that are up, which is better (in my case) than just a count of devices existing in the group.

In the host template I have
Type: Calculated
Key: device.host_alive
forumula: last("ssh.run[sshcheck,{HOST.CONN}]")

(Our devices will still ping even if they lock up and SSH become unavailable, so to ensure the device is functioning, we use an SSH check.)

Then in the aggregated template which calculates all values in a host group,
grpsum["{$GROUPNAME}","device.host_alive",last,0]


I tried using grpsum["{$GROUPNAME}","ssh.run[sshcheck,{HOST.CONN}]",last,0], but it didn't like {HOST.CONN}. Macros make things easy, but I suppose not this easy. haha.

Thank you very much!

Good to you!
I'm happy that you found the solution.

Does this solution hold up with version 5.0.2? I'm trying to accomplish something similar but haven't been able to put all of the pieces together yet.
