mount point monitoring through NCPA

[sunnynani4849]

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 kyang,

Thanks for the update and sorry for the delay.

iam trying to monitor the mount points but its showing the output for only the '/' partition.

Hi @sunnynani4849,

Instead of passing the -p
try passing

Code: Select all

'w 10% -c 20% -M /opt'

Let me know if this helps you.

Hi kyang,

After changing the option to -m for the mount point but still getting the same issue.

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

[sunnynani4849]

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

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'

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;
