Again, noob but have a home lab im trying to learn on, using ubuntu and centos

I have been following the doc’s as best i can and pieced stuff together to try an accomplish collecting custom metrics that are flowing on the event bus and putting it into influx for reporting purposes but i am failing at this point, have posted some lines from syslog and my handler and check configuration bellow. is anyone aware of a complete walkthrough on how to do this? I’m pretty sure once i see what i have done wrong it will open up my eyes.

once i get checks sorted out i will start to play with some plugins, also want to do something with statd as well but just baby steps right now

(posted in yaml format, is json easier to read?)

i have also used the format graphite\_plaintext and receive a similar area

Many thanks for any response  
Andrew

Hi @ohhfine, the issue I see right off the bat is that you’re using the `check-cpu` script, which doesn’t provide any metric data. If you wanted the status as a metric, you’d need to use the `-c` flag in your handler definition. Otherwise, you’d want to use `metrics-cpu` as your script. Another alternative would be to use a script that outputs nagios perfdata, which gets you both status and metric data in one script. The [nagios foundation collection](https://bonsai.sensu.io/assets/ncr-devops-platform/nagiosfoundation) is a good one to use in this case.

this is very good thank you for the quick feed back, so the script i am using outputs this in event console

“CheckCPU TOTAL OK: total=0.1 user=0.0 nice=0.0 system=0.1 idle=99.9 iowait=0.0 irq=0.0 softirq=0.0 steal=0.0 guest=0.0 guest\_nice=0.0”

i will read up on the -c flag for handler but will look at your other suggestions by changing the script in the check

Thanks again Aaron
