How can i count active host?

[israferna]

Hi!,
I´m using zabbix 2.2.2 and i want to know how many davices are up at , for example, 5 p.m. and sent that by e-mail. The e-mail job is just done, but i don´t how to count the devices.
I was thinking about using the count function in a trigger, but i´m not sure if that would work.
If someone could help me, it would be great.
Thank in advance.

If you ever figured this out, please share. I'm faced with the same problem with no end in sight. *edit* I'm on version 5.0.2 of the appliance.

OMG... Still using 2.2.2?

BTW.
Look in doc: https://www.zabbix.com/documentation...types/internal
Especially this: zabbix[host,<type>,available]

So if I understood this correctly, I created a template called DeviceCount (because I want to be able to apply this to many hosts in a particular host group). Within the DeviceCount template, I created an item called PingItem which is a simple check and uses the key "icmpping[<target>,<packets>,<interval>,<size>,<timeout>]". I left the default of numeric (unsigned) for the type of information. I set the update interval to 30m. I defined a custom interval of 30m, flexible, with a period of 1-4, 07:30-17:30 (because I want this to occur every half an hour during business hours while I am testing it). I'm not interested in keeping history or trend storage.

Next I have to create a trigger within the DeviceCount template, lets call that StatusReport. I'm leaving the severity as not classified for now. In the expression, this is where I would count the number of hosts that answered PING? So for the expression I am using "grpsum["TargetHostGroup","icmpping"[/,total]",last]".

And finally, I setup the action which is to email me the result of the StatusReport trigger based on a schedule of my choosing. Am I logically correct in all of this? I appreciate your input and thank you splitek!

PS: I already have a different action configured to alert me (via email) when a host doesn't answer ping, that is working correctly.

I forgot to mention that. Before I did any of the steps I mentioned in the previous post, I created a dummy host called PingTrapper and linked the DeviceCount template only to it.
