How to custom alarm information?

[Nathan]

Hello everyone,
please tell me how to add the configuration items of the HostMetadata configuration item on the agent side to the alarm information through the alarm information？
REALLY NEED TO HELP!
Thanks for everyone

Yep,you are right
And I knew it from manual, so what should I do? How to get a value from agent? No Hostname item

[Nathan]

thank you very much for your help
The current situation is that I want to set a value on the agent side. This value may be very long. This value is a string of strings automatically generated by the script when installing the agent, and I want to quote this string in the alarm message. what should I do?
It should be noted that the monitoring adopts active monitoring method. I imagined using macros or sending parameters to the server, but these are not good methods.
thanks again

You can use in Trigger text values of items, what you use for trigger expression. Get the value from file into item and use it with your expression. Something trivial, that is always true and won't affect rest of the expression. strlen>0 or whatever...then you can use {ITEM.VALUEx} in alarm text. Not too manageable way, if you want to do it for everything and globally... Adding it to each and every trigger is just pain...
If you send out notification with actions, then you could get this data into host inventory (read from file and populate inventory field) and use {INVENTORY.*} tags in forwarded event. In that case trigger itself wont have info but forwarded thing has.

ya it's gone work with the asset management. Well i used to get the same issue but got resolved the trigger expression.

Do I get this correctly, you want to use things from Metadata in alarms generated by host?

"Host metadata is used only at host autoregistration process (active agent)."
So... You can do autoreg operations based on this data, but there is no option to use it directly in any alarms.
