Below are some more details:
define command{ command_name check_kafka command_line /usr/local/nagios/libexec/nagios-plugins/check_kafka.pl -H $HOSTADDRESS$ -P $ARG1$ -T $ARG2$ -R $ARG3$ }
check_command check_kafka!9092!nagios!ISR
Zoom in for screen shot, which displays plugin error:
Have you tried the Python version for comparison? It may yield a different error message as this is generated from the underlying library. I personally prefer the python version now.
Hey Hari,
I have tried Python version, it doesn't show same error again but there is another status info, below is the same:
Status Info: Initial Service Pseudo-State
Could you please confirm if we need to worry about this message. If you can give some details like when this message appears, will be great help for us.
Thanks Pritpal
Please run it on the command line with the -v -v -v
switches to get full debug output and paste full output here. Might be worth doing for both the Perl and Python versions of check_kafka as they both support this for debug logging.
You can use anonymize.py from DevOps Python Tools repo if you want to redact your hostname/IP addresses from the text before pasting it here.
Hi Hari,
Thanks for the response

@ethan-riskiq Did you try the python check_kafka.py plugin to see if it gives a more informative error than the Perl API is returning?
Also, I think you should use one more -v
switch, three levels of verbose will get debug output including more output from the API.
I have not been a able to reproduce the issue via the python version of the script. I've added a "-new" check that's using the python verison of the script and will see if similar issues occur when the perl script returns this error.
https://gist.github.com/ethan-riskiq/25a2168b8143c8a59c807c41344154dc gist of python debug output. got UnknownError: failed to find matching consumer record with key error
That's an old version of check_kafka.py - 0.3.9, current is 0.5.3.
Can you please make update
and then try again with the latest version so that the traceback matches the current code for debugging?
Hi Hari,
we are using perl nagios plugin in our environment. we have recently deployed it. however we have observed some blips in nagios trends for kafka brokers, we thought that plugin went critical because kafka is having issue, but that's not the case, these blips are coming frequntly and pluging reports below error:
State info: CRITICAL: Error: Cannot receive: topic='nagios'
Not sure if this is known error in plugin, could you please suggest
