Accept All Items Matching Pattern

[gpmidi]

Zabbix sender could be used to capture data for a LOT more dynamic data sources (such as every pid+name combination) if it were possible to create a "template" item that would accept all items from zabbix_sender that match a given pattern. The newly created items should have the properties of the template item.
One example would be a script could report CPU time used for every process on a Linux machine. The key would be something like "process.cpu.seconds[<pid>,<exec name>]". Each process would have a unique key. This would result in a separate data stream, and thus separate graphs, for each process. It would then be possible to view the CPU usage of any process on a system.

What about processes that die and respawn with a new pid?

You would end up with a new stream. It's just an example of something that would be able to take advantage of such a feature. It's not the sole reason.

That's the point..

In a few months you'd get item's multiplying like rabbits and you'd lose the historic relation between them.

It'd have to have a different variable than pid, else we'd end with a separate Graph for a given process for the timespan 03Fev..14Fev, 14Fev..18Fev,18Fev..10Mar,....

Yes, you would have a problem with ending up with LOTS of items. In the way I was thinking about it you would need some way for the items to expire after a certain time. Plus the GUI would need to be better able to support 10k+ trapper items per host.

The more Zabbix-friendly solution is to simply use something else as the key. While possible it does reduce the depth of the information gathered. OTOH it does make life a lot easier.
