Few logs are getting truncated

splunklearner — Thu, 05 Jun 2025 07:31:21 GMT

Few event logs are getting truncated while others are getting perfectly. We are using akamai add-on to pull logs to Splunk.

HF (akamai input configured) ---> sent to indexers

in DS all apps will be there (where all props and transforms) which will be pushed to CM and from CM will be pushing to individual indexers.

props.conf in DS (Ds --> CM --> IND)

[sony_waf]

TIME_PREFIX = ^

MAX_TIMESTAMP_LOOKAHEAD = 25

TIME_FORMAT = %b %d %H:%M:%S

LINE_BREAKER=([\r\n]+)

NO_BINARY_CHECK = true

EVENT_BREAKER_ENABLE = true

SHOULD_LINEMERGE = False

TRUNCATE = 50000

Few logs are getting perfectly. what to do now? Please suggest.

Hi @splunklearner

You mention that the props/transforms are pushed to your Indexers, but is it also installed on the HF pulling the Akamai logs? Can you validate that the relevant props/transforms with the TRUNCATE set to a higher-than-longest-event value are installed on the HF?

$SPLUNK_HOME/bin/splunk btool props list sony_waf --debug

If you run this on your HF you should see your TRUNCATE value to the expected high value.

What length are your logs being truncated to?

Your approach of using DS->CM->IDX is interesting...but I dont think this is the problem here if the Akamai logs are being pulled by a HF - Ultimately we need to ensure the HF has the props!

when I checked more in depth logs, I see perfect logs have less than 10000 lines where the logs which are truncating have 10001 lines. But I set truncated value to 50000 why this is not applying?
