Yes.

https://<ip address>:5693/api/disk/logical/%7C/used_percent

Code: Select all

{
  "value": {
    "used_percent": [
      9.1999999999999993, 
      "%"
    ]
  }
}

What are the results of the following commands?

Code: Select all

ll -d /usr/local/nagios/var/spool/
ll -d /usr/local/nagios/var/spool/checkresults
ll /usr/local/nagios/var/spool/checkresults | wc -l

Did you restart the "ncpa_posix_passive" after making the changes to the "ncpa.cfg"? Can you show how the passive disk check is defined now? Can you run an active check successfully from the Nagios XI server?

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H <remote ip> -t 'token' -P 5693 -M 'disk/logical/|/used_percent' -w 80 -c 90

Yes, I restarted the ncpa_posix_passive after making changes. Active checks work fine. Its passive checks we are having issues with.

Can you show how the passive disk check is defined now in the ncpa.cfg?

Also, try deleting both disk checks in XI (disk root used percent & disk-root-used-percent), and re-configure the check, when it shows up in the Unconfigured Objects.

I have the 1.7 version of the ncpa agent now, however, I am still not sure how to define this passive check:

Code: Select all

%HOSTNAME%|disk root used percent = /disk/logical/'|'/used_percent --warning 80 --critical 90
With the 1.7 NCPA Agent now I'm getting a bunch of other stuff I didn't see before, something seems broken from what I had before. Running on Redhat 6 so used the CentOS 6 RPM.

Also, here is the ncpa.cfg file right now:

[passive checks]
#%HOSTNAME%|cpu usage = /cpu/percent --warning 20 --critical 30

#%HOSTNAME%|memory usage = /memory/virtual/percent --warning 60 --critical 80
#%HOSTNAME%|disk root used percent = /disk/logical/'|'/used_percent --warning 80 --critical 90


Really need to get this linux client working better so I can start deploying it. I can't use it if its going to be broken like this.
Thanks!
