NRPE Output Size

[ssoliveira]

Good evening,

My graphics are having problems because information is being truncated by check_nrpe.

Calling the command locally is returning correctly.

Code: Select all

 [root@datalog-ugt-log1 libexec]# /usr/bin/check_elasticsearch
Monitoring cluster 'a5726a09-769e-4f2b-be91-d786c8165c6f' | cluster_nodes=4;;;;; cluster_master_eligible_nodes=4;;;;; cluster_data_nodes=4;;;;; cluster_active_shards=1038;;;;; cluster_relocating_shards=0;;;;; cluster_initialising_shards=0;;;;; cluster_unassigned_shards=0;;;;; cluster_total_shards=1038;;;;; cluster_total_indices=70;;;;; cluster_closed_indices=0;;;;; storesize=2124557370946B;;;;; documents=1920168754c;;;;; index_ops=737278752c;;;;; index_time=322062338ms;;;;; flush_ops=9641c;;;;; flush_time=1228456ms;;;;; throttle_time=217690564ms;;;;; index_ops=737278752c;;;;; index_time=322062338ms;;;;; delete_ops=198c;;;;; delete_time=57ms;;;;; get_ops=630539c;;;;; get_time=106761ms;;;;; exists_ops=630536c;;;;; exists_time=106761ms;;;;; missing_ops=3c;;;;; missing_time=0ms;;;;; query_ops=1418392c;;;;; query_time=86096168ms;;;;; fetch_ops=1158580c;;;;; fetch_time=575445ms;;;;; merge_ops=362208c;;;;; refresh_ops=1825688c;;;;; refresh_time=60179314ms;;;;; gc_old_count=21995c;;;;; gc_young_count=185113c;;;;; heap_used=74%;;;;;

However, calling via check_nrpe, it is truncating after the character 1024

Code: Select all

[root@datalog-ugt-log1 libexec]# ./check_nrpe -H 127.0.0.1 -t 90 -c check_elasticsearch

Apparently there is a limit on the amount of characters processed.
How can I configure NRPE to return the complete string?

Version 2.15 of the NRPE agent and plugin does have a limit in the amount of data that is sent in the buffer but the newer 3.x.x version has increased the size of the buffer that transfers the data so it should not get cut off.
You would have to recompile the Agent and the plugin for this to work and the instructions for doing that can be found here.

Is it ok if we go ahead and close this?
