Field Calculation not working

New Member

What I'm trying to do is create a field named idstype and make it equal to network. (idstype=network)

I'm trying to add a new field to a sourcetype. The name of the field is idstype. I created an eval statement that works when i run a search. But when I save it as a calculated field it doesn't seem to work. The eval expression is if(rectype="400","network",null). I have refreshed Splunk, restarted Splunk and changed the permissions of the field calculation to all apps. But it doesn't seem to be working. what else can I troubleshoot?

Does the rec_type field exist? What are the permissions for it?

Yes the rectype field does exist it. I have tried several eval statement such as eval idstype="network" and that still didn't work. Not sure what I'm doing wrong.

Is rec_type numeric? Because, you're comparing it to the string "400". Remove the quotes and you should be fine. To be extra sure, you could use tonumber() to convert.

if(rec_type=400, "network", null)
OR if that doesn't work:
if(tonumber(rec_type)=400 , "network", null)

ha! I was about to suggest that too, but i refreshed the page and you beat me to it!

Its also worth checking that your sourcetype is set correctly, the result of the calculated field should look like this is props.conf

[your_sourcetype_name]
EVAL-ids_type = if(rec_type=400, "network", null)

I'm not sure if it makes a difference, but try to replace null with null().

If anyone is having the same problem with the TA-eStreamer add on, the field is supposed to be defined using a built-in lookup to sources.csv. In the lookup file the source is defined as estreamer whereas the encore app is now has a source of encore. To fix the problem updated the sources.csv lookup file and add another line :

source,vendor,product,ids_type
eStreamer,Cisco,Sourcefire,network
encore,Cisco,Firepower,network
