Usage of Splunk EVAL Function : SEARCHMATCH

                                         Usage of Splunk EVAL Function : SEARCHMATCH

       Returns true if the event matches the search string X.

      Find below the skeleton of the usage of the function "searchmatch" with EVAL : 

                                               searchmatch(X)

index=_internal 

| eval AA=if(searchmatch("Queue Full"),"Exists","NOT")

Explanation :

             If any event in the "_internal" index is having 

             "Queue Full" String in it, then "Exists" will be 

             stored in the "AA" field which is newly created.

             If not then "NOT" will be stored in the "AA"

             So, there are total 5990 lines with "Queue Full" 

             and 5452 without "Queue Full"

           

Verification :

   index=_internal 

   | eval AA=if(searchmatch("Queue Full"),"Exists","NOT")

   | search AA="Exists"

Only those lines will appear which has "Exists" value in AA field,

which means "Queue Full" string is there in the event.

Similarly , you can also verify for AA="NOT" and you will get 

only those lines which do not contain "Queue Full" String in it.

Now you can effectively utilize "searchmatch" function with "eval" command to meet your requirement !!
