Where are you seeing the output truncated?
If you're referring to the status displayed in XI. This link outlines how to do so -

Did you take a look at the link provided by
@rkennedy above? That shows how to expand the database tables to allow for longer status output. Bear in mind this will only affect new results going forward, not previous results.

My question was rather wrong.
Actually I need to increase the NRPE agent output from 1 KB to 4KB .

What is the NSClient++ version that you are currently using? Can you post the nsclient.ini file?

What version of NRPE are you running? I believe only the version that will support 4k is going to be NRPE RC.

NRPE 2.16 RC2 supports up to 64K. You will need to recompile NRPE on both ends in order to make this work - on the Nagios XI server, and the client (SLES 12 machine).

Hope this works.
