RAM usage calculation

[PiotrM]

Hi,
I'm monitoring several dozen Cisco routers. I've extracted information about RAM usage at specific values. I want to create a trigger that will calculate the percentage usage and raise an alert. Routers have different amounts of RAM in different models. How can I solve this? Thanks in advance for your help.

regards
Piotr

Hello

Would make sense to gather RAM usage for every router in a separate item, total RAM available can be stored as a host macro. Afterwards, percentage can be retrieved as a calculated item using the last value of RAM usage divided by that available RAM host macro; trigger can be created based on that calculated item.
