I have a macro which is in the format:
match($field$,"regex1") OR match($field$,"regex2") OR ...
When I use it in snippet like this:
| stats count(mvcount(mvfilter(`macro-name(field=fieldName)`))>0) AS something
While the search is running, I can see "something" gets incremented but suddenly drops to 0 when the search is finalised. If I run the above again but replace the macro invocation with its actual macro content, i.e.:
| stats count(mvcount(mvfilter(match(fieldName,"regex1") OR match(fieldName,"regex2") OR ...))>0) AS something
"something" actually returns a non-zero result. Another experiment I tried was the following instead of the stats:
| where mvcount(mvfilter(`macro-name(field=fieldName)`))>0
And the number of the results I get back is identical to value of "something" in the last stats snippet.
So it seems to me there is something about using macros inside the count function, that Splunk cannot handle. Am I doing something wrong or is this a known limitation?
You are calling your macro wrong. You should call it as macro-name(fieldname)
. There might be more wrong, but this problem is fatal.
I have encountered similar issues when using stats in a saved search which is called via "savedsearch" command.
