I'm very new to Splunk and need to get some details about a transaction which spans multiple events. Am trying to get my head around how transaction works or if this can even be done without using transaction.
Sample logs:
Feb 18 21:45:15 smtp2 sm-mta[9562]: l1J3iwHw009562: to=, delay=00:00:17, pri=14653393, stat=Message exceeds maximum fixed size (8000000)
Feb 18 21:45:15 smtp2 sm-mta[9562]: l1J3iwHw009562: message size (14623393) exceeds maximum (8000000)
Feb 18 21:45:15 smtp2 sm-mta[9562]: l1J3iwHw009562: from=, size=14623393, class=0, nrcpts=1, msgid=64db010c0702181944g15241075qf40af0a1cb398e30@mail.example.com, proto=ESMTP, daemon=MTA, relay=wr-out-0506.example.com [64.233.184.225]
Flow of what needs to be achieved:
1. Search for an event where stat!=Sent.
2. Search for all other (2) events with the same qid (l1J3iwHw009562).
3. Extract other information from the transaction such as msgid, size, from, to
I have tried a variety of different things but really think this should return what I want, but it does not.
index=maildata | transaction qid startswith="stat!=Sent" endswith="msgid=*"
Thanks in advance
Based on the discussion from the other answer, I have a suggestion:
index=maildata
| stats first(stat) AS stat, values(msgid) AS msgid, values(size) AS size, values(from) AS from, values(to) AS to by qid
| search stat!="Sent"
Hi, were you able to properly identify and extract the time format for this event ?
Based on the discussion from the other answer, I have a suggestion:
index=maildata
| stats first(stat) AS stat, values(msgid) AS msgid, values(size) AS size, values(from) AS from, values(to) AS to by qid
| search stat!="Sent"
I really appreciate your help and can now see how this is better than transaction. Thank you
Try this variation on your query.
index=maildata | transaction qid startswith=eval(stat!="Sent") endswith="msgid="
Here's a similar query that doesn't use transaction
.
index=maildata | stats values(msgid) as msgid, values(size) as size, values(from) as from, values(to) as to by QID
Thanks Rich. Unfortunately neither of those are returning results for me. Interesting that it can be done with stats, that would greatly improve the search time indeed.
Does the latter return results for you if you replace QID
with qid
? Splunk is case-sensitive about field names. You referenced it in one place in caps and another place in lower-case, so I thought I'd toss this out.
If not, that suggests that maybe your field extractions aren't functioning as expected.
Apologies, yes I tried with lower case qid and it did work. However, it needs to return details about a session (qid) only if the session contains an event where stat!=Sent. This answer returns everything back.
