Can you show the supermetric from the legacy screen
supermetric in legacy mode is :
(${this, metric=mem|usage_average})
and show the output
Actually I decide to write supermetric for one issue . There is strange problem on one of my machines. This machine has 32G memory
now Memory usage is 94% but Guest free memory is more than 20G what is the problem ?
The guest OS is linux thus I decide to write a supermteric that can calculate total capacity - guest free memory to find memory usage
Do you think is that correct ?
(${this, metric=mem|usage_average}) is not the metric you are using in the screenshot. If it was then you would not have virtual machine in the text. a this formula should look like the below
If i had to guess it is because you picked a metric and not a this and didnt add a function at the start so it didnt know what to do with the metric (sum, min or max it etc)
