Hi ,
Iam trying to monitor the mount point (/opt/splunk/var/lib/splunk/cold/) via NCPA agent. I have searched some website that mount point monitoring cannot be done via NCPA agent.
So i am trying to monitor this via check_disk plugin through the NCPA agent, but getting the below errors. Please help with the below issue

Hi
@sunnynani4849,
It looks like the command arguments are not being passed correctly,
Try this, without -a and without agent
Code: Select all
-M 'plugins/check_disk/-w 10%/-c 20%/-p /tmp'
Or this one
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H 192.168.x.xxx -t '<token>' -M 'plugins/check_disk' -a '-w 10% -c 20% -p /tmp'
The output should be like this.
Code: Select all
DISK OK - free space: / 17556 MB (67.01% inode=91%);| /=8640MB;24838;22078;0;2759
Post your output or let me know if this helps

Hi
@sunnynani4849,
Instead of passing the -p
try passing
disk.PNG
Let me know if this helps you.

What version of NCPA do you have installed in the remote system and can you post your ncpa.cfg file?

hi tgriep,
on the client server NCPA 2.0.2 rpm is installed on the server. Please find the attached NCPA configuration file

The -M for check_disk is case sensitive, but it actually does not take a value at all. You can only specify using -p. The -M command only shows the mount point instead of the partition in the output.
Code: Select all
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_nagios-lv_root
27G 8.9G 17G 35% /
tmpfs 1.9G 440K 1.9G 1% /dev/shm
/dev/sda1 477M 127M 325M 29% /boot
The first run assumes / because you are not actually passing the -p value and -M displays the mount point. The second two are using a path, without -M. The last one uses -M and -p.
Code: Select all
[root@nagios libexec]# /usr/local/nagios/libexec/check_ncpa.py -H localhost -t 'mytoken' -M 'plugins/check_disk' -a '-w 10% -c 20% -M'
DISK OK - free space: /dev/mapper/vg_nagios-lv_root 17168 MB (65.53% inode=90%);| /dev/mapper/vg_nagios-lv_root=9028MB;24838;22078;0;27598
[root@nagios /]# /usr/local/nagios/libexec/check_ncpa.py -H localhost -t 'mytoken' -M 'plugins/check_disk' -a '-w 10% -c 20% -p /boot'
DISK OK - free space: / 17167 MB (65.53% inode=90%);| /=9028MB;24838;22078;0;27598
[root@nagios /]# /usr/local/nagios/libexec/check_ncpa.py -H localhost -t 'mytoken' -M 'plugins/check_disk' -a '-w 10% -c 20% -p /dev/shm'
DISK OK - free space: / 17167 MB (65.53% inode=90%);| /=9028MB;24838;22078;0;27598
[root@nagios libexec]# /usr/local/nagios/libexec/check_ncpa.py -H localhost -t 'mytoken' -M 'plugins/check_disk' -a '-w 10% -c 20% -p /boot -M'
DISK OK - free space: /dev/mapper/vg_nagios-lv_root 17167 MB (65.53% inode=90%);| /dev/mapper/vg_nagios-lv_root=9029MB;24838;22078;0;27598
Also it seems like the check_disk won't return the partition data, and if you wanted to get that, you could just do it with NCPA
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H localhost -t 'mytoken' -M 'disk/logical/|boot' -w 70 -c 90 -u M
OK: Used disk space was 28.10 % (Used: 132.94 MB, Total_size: 499.36 MB, Free: 340.20 MB) | 'used_percent'=28.10%;70;90;
