Applicability

Splunk Enterprise Splunk Cloud

Description

In the Splunk Add-on for Unix and Linux, while ingesting the `ps_metrics.sh` scripted input, some fields containing more than 2048 characters are being truncated, resulting in incorrect field data population.


Investigation



-> Here, the characters of the fields are getting exceeded from 2048 characters limit, hence its getting truncated

- > The maximum allowable length of an indexed field including the <fieldname>:: prefix is 2048 chars. Therefore, any field containing data exceeding 2048 characters will be truncated. 


Resolution

There is no resolution or workaround to get past this limitation ( Chars limit is hardcoded ) other than splitting the value into multiple fields and then concat the fields together during the search.
