Splunk Search

search question

In the search field, I entered: source=/logs/*/*.log it matches /logs/*/*.log and /logs/*/*/*.log. I need to see only the /logs/*/*.log entries and not the /logs/*/*/*.log entries. What should I change on the "search string" ? Thanks.

You're seeing log/*/*/*.log because Splunk interprets the wildcard "greedily", i.e. it will match as much as possible.

There is no way that I know of to make the wildcards non-greedy, but there are workarounds that you can use. One is to specify explicitly that you want sources that match /logs/*/*.log but not /logs/*/*/*.log:

source="/logs/*/*.log" AND NOT source="/logs/*/*/*.log"

Or you could use regex to filter results, like below.

source="/logs/*/*.log" | regex source="/logs/[^/]+/[^.]+\.log"

try: source="/logs//.log" NOT source="/logs///.log"

eventually with backslashes. But really you should avoid the wildcard in searches for performance reason
