Hi,
I'm facing issue with chart which displays KG and MB, where MB are bigger by the number, and it shows wrong chart:
Green line needs to be above.

event examples:
Heap: 13.2G
Heap: 6208.6M

How make, that MB are down in the chart?
alt text

My search:
| rex Heap:\s(?<HeapNum>\d+\.\d)\w | search HeapNum!=" " | eval critical=15 | table _time HeapNum critical

You should first define what is the base unit you want to work with (Kb, Mb, Gb, etc) . For this lets assume Mb

| rex "Heap:\s(?<HeapNum>[\d\.]+)(?<unit>\w+)"
| search HeapNum!=" " 
| eval HeapNum = case(unit="K", HeapNum/1000,unit="M", HeapNum,unit="G", HeapNum*1000)
| eval critical=15 
| table _time HeapNum critical 

You can change the calculations in the case depending on the selected unit. And then also revise the critical value accordingly.

Hope this helps.

assuming HeapNum is your MB field | eval HeapNum=round((HeapNum/1000),2)

@Sukisen1981 It also round 13G 😞
but with 3400M it works good!
