NCP Agent not detecting XFS File System

Hello There,
Does NCP Agent v2.3.1 support monitoring of XFS File System?
Before upgrading to the latest version of NCP Agent, Disk usage monitoring of XFS FS was working fine, but post upgrade, the FS is not being detected.
When I check in the NCPA Web Console of the respective server, it does show the XFS FS.
Any inputs please?

I just labbed this up and it's showing xfs on NCPA v2.3.1 properly.
Does it show here? (select API > Disk > Logical)
- Change X.X.X.X to the IP of the NCPA host, open it in a web browser
Are you seeing any errors in your ncpa_listener.log on the NCPA host?

Yes, I can see all the disks "xfs" when I access the NCPA Console.
Attaching the web console screenshot for reference.

I can see the FS in NCPA Console, but the issue here is, when I create a Disk Usage Service, it fails on me.
Code: Select all

Hi,
Please upload the command you used, which produced the error in your last reply.
Also, please run the below command and update
ALL outputs to this thread so we can work on the issue:
(NOTE: x.x.x.x is the IP address of the remote NCPA machine. You can get the "token / community_string" in the "/usr/local/ncpa/etc/ncpa.cfg" file on your NCPA remote machine)
Code: Select all
curl -k 'https://x.x.x.x:5693/api/disk/?token=yourToken'
Best Regards,
Vinh

Here is the command:
Code: Select all
[root@nagios1 ~]# /usr/local/nagios/libexec/check_ncpa.py -H xx.xx.xx.xxx -t <tokenID> -P 5693 -M 'disk/logical/|var|lib|ceph|osd|ceph-11/used_percent' -c 90 -w 85
UNKNOWN: The node (/var/lib/ceph/osd/ceph-11) requested does not exist. You may be trying to access the '/' node.
I will pm you the output of curl command.

Hi,
Could you please also update the output of the below "df" command?
I need that to compare with the curl outputs.
Regards,
Vinh

Hi,
Based on the outputs of "curl", we have the following tree structure (example):
Code: Select all
"disk": {
"mount": {
"|var|lib|ceph|osd|ceph-63": {
"fstype":
"opts":
"device_name":
},
"logical": {
"|boot": {
"used_percent":
"used":
"inodes_used":
"free":
"device_name":
"inodes_free":
"inodes":
"fstype":
"total":
"opts":
"inodes_used_percent":
},
"physical": {
"sdf3": {
"read_time":
"read_bytes":
"write_count":
"write_time":
"write_bytes":
"read_count":
},
Here are some example of "check_ncpa.py".
If I want to find "/boot", I would follow the tree down ....
"disk/logical/|boot/used_percent"
or
"disk/logical/|boot/inodes_used" ..... you get the idea here ....
Code: Select all
disk:
"logical": {
"|boot": {
"used_percent":
"used":
"inodes_used":
"free":
"device_name":
"inodes_free":
"inodes":
"fstype":
"total":
"opts":
"inodes_used_percent":
},
Based on the structure of "curl" output, I can contruct the "check_ncpa.py" .... please see example below:
If you want "use_percent' of "/boot" filesystem, your command must be like this:
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H xx.xx.xx.xxx -t <tokenID> -P 5693 -M 'disk/logical/|boot/used_percent'
"free" on "/boot":
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H xx.xx.xx.xxx -t <tokenID> -P 5693 -M 'disk/logical/|boot/free'
"free" on "/" filesystsem:
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H xx.xx.xx.xxx -t <tokenID> -P 5693 -M 'disk/logical/|/free'
"read_bytes" of "sdf3":
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H xx.xx.xx.xxx -t <tokenID> -P 5693 -M 'disk/physical/sdf3/read_bytes'
List "device_name" of "|var|lib|ceph|osd|ceph-63":
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H xx.xx.xx.xxx -t <tokenID> -P 5693 -M 'disk/mount/|var|lib|ceph|osd|ceph-63/device_name'
List "fstype" of "|var|lib|ceph|osd|ceph-63":
Code: Select all
/usr/local/nagios/libexec/check_ncpa.py -H xx.xx.xx.xxx -t <tokenID> -P 5693 -M 'disk/mount/|var|lib|ceph|osd|ceph-63/fstype'
As you can see, the "curl" output is very useful. You used that to setup your "check_ncpa.py" call with the "-M" option.
Best Regards,
Vinh
