How do I combine multiple problems reports into one, and list the hosts

[Callie]

Hi,

I've got a zabbix environment where we have an item in pace on each host that tells us how many security updates are available for that host, and then a trigger to report when there are any security updates.

We've got a few hundred hosts, so we get a lot of problems generated.

I'd much rather generate a single problem, that contains a lists of all the hosts that have updates.

Is there a way to do this within zabbix?

I have generated an aggregate check (using grpsum[]), against that initial item, which is great, a single report of hosts needing updates - but no apparant way to list the hosts.

I'd rather not write a new item that does it's own monitoring of the security updates, so it could return a list of hosts.

I might have to write my own external test that searches through the zabbix DB, in order to get that list of hosts. Again, I'd rather not, but it is better than the previous option.

I think I'm sort of asking for a grplist[] aggregate function, as opposed to the existing grpavg, agrpmax, grpmin, & grpsum functions.
