NCPA Agent - AIX 7.1 Fails / AIX 7.2 Works (UNKNOWN: An error occured connecting to API. (HTTP error: '500 INTERNAL SERVER ERROR') )

Good Day,

As per title, we have installed the NCPA Agent on a handful of AIX Servers. The AIX 7.2 Servers report back fine but the AIX 7.1 Servers fail as follows :

# /usr/local/nagios/libexec/check_ncpa.py -H XXXXXX -t 'XXXXXX' -P 5693 -M 'plugins/check_entitlement' -a '-ew=95% -ec=100%'
ENTITLEMENT CRITICAL ent_used=0.16(CRITICAL) ent=0.05 ent_max=1 vcpu_busy=15.94%(CRITICAL) |ent_used=0.16 ent=0.05 ent_max=1 vcpu_busy=15.94

# /usr/local/nagios/libexec/check_ncpa.py -H XXXXXX -t 'XXXXXX' -P 5693 -M 'plugins/check_entitlement' -a '-ew=95% -ec=100%'
UNKNOWN: An error occured connecting to API. (HTTP error: '500 INTERNAL SERVER ERROR')

I have queries the AIX Engineer about the Servers locale / lang setting but they have confirmed it is the same. It was the only reference I have found to date that is similar to this issue.

Can you check in the log file /usr/local/ncpa/var/log/ncpa_listener.log ? there should be some output in there related to the 500 error that might explain the issue.

Can you run the check manually as the 'nagios' ID on the 7.2 server? Validate what return code it's returning
