NetXMS Support Forum

Probably that's a stupid question, but I still don't understand what to specify for DCI {instance}. How to find out these instances? Talking about NetXMS_agent as origin.

Okay, I understand FileSystem.FreePerc(/) or System.ServiceState(name_of_my_service).
What should I put, for example in Hardware.Processor.Family(*) ?

Unless you are looking for a very specific instance, you will want to use Instance Discovery.
In which case you'd configure your DCI using something like FileSystem.FreePerc({instance}) and under Instance Discovery you'd select Agent List as Instance discovery method followed by entering FileSystem.MountPoints as List name.
You can get a list of available agent lists by right-clicking on a node and selecting (I think) Info->Supported Lists. We've changed our menu structure, so not sure what the default is.
For your Hardware.Processor.Family(*), I'd guess the list to use is "Hardware.Processors" (taken from the supported lists on one of my agents).

The whole idea of Instance Discovery is that you don't need to enter every item manually. Nor do you have to worry about what happens when something changes, Instance Discovery runs regularly and will pick new items up and remove old ones (you can configure how long you want to keep the data once an item is no longer found).

Thank you for giving really good directions:

Bingo. Then followed by nxget utility and I finally see the instances:

nxget -l my_host Hardware.Processors

Yes, I completly agree. Just tested few simple things - it works!
