relating fields with eval

[jrich523]

I have two fields (different sourcetypes) that have a Node ( for example: node001) and NodeID (example: 1)

How would i extract Node to NodeID dealing with the leading zeros?

First you'll need to search for events from both sourcetypes, then normalize your Node field to match the NodeID field, and then do whatever you're actually trying to do with the data:

  sourcetype=eventsWithNodeID OR sourcetype=eventsWithNode
| rex field=Node "0*(?<tempNodeID>\d+)$" | eval mergedNodeID = case(sourcetype="eventsWithNodeID", NodeID, sourcetype="eventsWithNode", tempNodeID)
| stats values(foo) as foo max(bar) as bar by mergedNodeID

Hi. Something like:

sourcetype=X OR sourcetype=Y | rename Node* as *

Can be an option.
