rangemap does not work with decimals?

Communicator

Hello,

I'm trying to get a rangemap command to work like the below.

| rangemap field=count low=0-.5 elevated=.5-1.5 default=severe

I'm getting an Invalid range: '0-.5'.'- expected.

Will the function not work with a number with a decimal in it? If I replace with whole numbers - like low=0-1 elevated=2-4, it works correctly.

Thanks

Update: As of Splunk 6.0 (possibly sooner), the rangemap command does support decimal values.


Yeah, decimals are not supported, which is funny since the underlying code uses "float"s, but the matching regex doesn't allow for a leading "." (dot), which is why you get the "Invalid range" message. From what I'm seeing, it seems like this would be a fairly trivial feature request; if you want this feature please open a support ticket with splunk.

That said, you can very easily use a case eval statement instead. Something like this should do the trick for you:

| eval range=case(count<0.5, "low", count<1.5, "elevated", 0==0, "severe")

It appears that the rangemap command allows for overlapping ranges, but the work-around given here does not. I doubt this will be a problem for you.
