Hi @super_saiyan,
You can update limits.conf to change the Show Source settings. The docs mention that results are "pruned" so while you increase the limit, you may still not get an increase in events displayed.
https://docs.splunk.com/Documentation/Splunk/latest/Admin/limitsconf#.5Bshow_source.5D
[show_source]
distributed = <boolean>
* Whether or not a distributed search is performed to get events from all
servers and indexes.
* Turning this off results in better performance for show source, but events
will only come from the initial server and index.
* Default: true
distributed_search_limit = <unsigned integer>
* The maximum number of events that are requested when performing a search
for distributed show source.
* As this is used for a larger search than the initial non-distributed show
source, it is larger than max_count
* Splunk software rarely returns anywhere near this number of results,
as excess results are pruned.
* The point is to ensure the distributed search captures the target event in an environment with many events.
* Default: 30000
max_count = <integer>
* Maximum number of events accessible by show_source.
* The show source command will fail when more than this many events are in the same second as the requested event.
* Default: 10000
max_timeafter = <timespan>
* Maximum time after requested event to show.
* Default: '1day' (86400 seconds)
max_timebefore = <timespan>
* Maximum time before requested event to show.
* Default: '1day' (86400 seconds)
Cheers,
Daniel
