Hi,
I would like to get Heap number, from event:
[Eden: 704.0M(5804.0M)->0.0B(5800.0M) Survivors: 52.0M->56.0M Heap: 7961.8M(15.0G)->7271.4M(15.0G)]

And get:
7961.8

Add this, your field name will be called HeapNum

| rex Heap:\s(?<HeapNum>\d+\.\d)\w

Thanks you a lot @skoelpin !
And, if I want to take number, which is in () brackets?

If the number is in the parenthesis and you want to exclude it, you would do something like this

| rex Heap:\s\((?<HeapNum>\d+\.\d)\)\w

Also for some reason, when I try with Metaspace, it shows no outputs.
Event:
[Eden: 180.0M(6104.0M)->0.0B(6104.0M) Survivors: 0.0B->0.0B Heap: 3159.0M(12.0G)->2979.3M(12.0G)], [Metaspace: 535433K->535433K(1574912K)]

| rex Metaspace:\s(?\d+\.\d)\w
| table metaspacenum
| head 10

output in Statics there there is noting, just empty tables
tried to exclude with | search metaspacenum!=" "
but it didn't helped

Like this

| rex Metaspace:\s(?<Metaspace>\d+)

To exclude nulls, like this

| where isnotnull(Metaspace)

Thank you for your replay, @skoelpin !
But if before parenthesis there is numbe like this Heap: 12.8G(15.0G), and 12.8 all the time is changing, and I need 15.0?
