Can any one help to understand & use of below command in eval
index=_internal | eval Mahesh=max(1, 3, 6, 7, "foo", field)
@maheshsat, please add a context as to why and where is this being applied. What are the typical values in field? Is it numeric or string?
Max will pull the highest in the list. Other way to analyze would be of you reverse sorted values, which value will be the first.
| eval field=1000
| map search="| makeresults
| eval data=\"1,3,6,179,foo,$field$\""
| makemv data delim=","
| mvexpand data
| sort - data
| head 1
PS: Take out head 1 command o see ranking of each values. Also change field value to its max value(string or number) to be added to the query.
