Changing message size globally in Splunk

[brent_weaver]

I have a few sourcetypes that are exceeding the message size limit of 10K and I would like to set this to 32767 for all sourcetypes. I know how to do it for an individual sourcetype, how can I do it globally? Can I put it in etc/system/local/props.conf in the default section?

Yes, that would be the proper approach based on conf file precedence

However, changing it globally will affect memory utilization since buffer allocation will use the higher value for everything, so I would probably raise the limit for those sourcetypes that need it. It also adds a level of 'documentation' to your sourcetype configuration that maybe helpful in understanding the input's characteristics.

Thank you for the great info... Totally makes sense. I will do it for the sourcetypes that need it. Do I need to consider the the UF config for those ST's affected? Do I need to do the same thing on the UF side?

Nope, only relevant where parsing happens, i.e. Heavy Forwarder (if used) or indexer.
