Sometimes the service-broker stats plugin returns this error:
UNKNOWN: Cannot decode json response: garbage after JSON object, at character offset 1917 (before ""compiled with qt":"...") at /usr/lib/centreon/plugins/centreon_centreon_central.pl line 279

Most of the times the check is ok but some times this error appears.

After searching on the web, I found that it may be caused by an error in the response which not return the expected json.

Tried with the debug option as suggested, but it do not give more information.

Command for the check is (and error answer):

 

 

 /usr/lib/centreon/plugins/centreon_centreon_central.pl --plugin=apps::centreon::local::plugin --hostname=127.0.0.1 --mode=broker-stats --broker-stats-file='/var/lib/centreon-broker/central-broker-master-stats.json' --broker-stats-file='/var/lib/centreon-broker/central-rrd-master-stats.json' --broker-stats-file='/var/lib/centreon-engine/central-module-master-stats.json' --filter-name='' --warning-speed-events='' --critical-speed-events='' --warning-queued-events='' --critical-queued-events='' --warning-unacknowledged-events='' --critical-unacknowledged-events='' --warning-status='' --critical-status='%{type} eq "output" and %{queue_file_enabled} =~ /yes/i' --verbose --debug UNKNOWN: Cannot decode json response: garbage after JSON object, at character offset 1917 (before ""compiled with qt":"...") at /usr/lib/centreon/plugins/centreon_centreon_central.pl line 279.

 

Centreon version is 

Centreon 19.10.23

(commit  13d8821f0)

 

I’d like to understand what causes this error.

Thanks

Hello, 

 

Hard to guess. 

 

Most of the time, this is because you get an extra system message about the file opening which result in the plugin failing because it expects full JSON. 

 

You shouldn’t be too worried about it. 

 

Note that access to this file is better handled with latest ventreon-broker versions.
