View Windows server or VMware guest VM CPU/RAM in simple %

[acatic1]

Using Zabbix 4.4.0 and Grafana. I'm a general noob in both, but have been intensely building them out over the past few weeks.

I'm trying to put together a table of my VM guest servers' performance values, similar to https://grafana.com/grafana/dashboards/5456.

When I test different keys such as vm.memory.size[free], system.swap.size[,free], vm.memory.size[total], I'm getting crazy values such as 2417164288.00% for free memory, which does correspond to the bytes available. I just want a neat number like 75%. What do I need to do for that? Is it a zabbix or grafana thing?

Use calculated item and simple expression for percent like this (free_memory/total_memory)*100

Thank you Hamardaban. How do I apply that? Is ‘free...100’ the key for the item?

I saw people mentioning that calculation, I just didn’t see how it is actually applied.

Sorry.... There is an easier way to get "percent" - use "vm.memory.size[pused]" or " vm.memory.size[pavailable]" and "system.swap.size[,pfree]" ( pfree (free swap space, in percent), pused (used swap space, in percent))
