[Gluster-users] Monitoring tools for GlusterFS

[Gilberto Nunes]

Hi guys...  I miss some tools that could be used in order to monitor
healing for example, and others things like resources used...  What do you
recommend?
Tools that could be used in CLI but that shows a percentage as healing is
under way would be nice!

Thanks.

Hello Gilberto,
I've had the same questions and some of the community friends were kind
enough to send me a few things to look for

However as you have stated it would be interesting to know exactly how to
monitor the healing process.
A friend mentioned some things we should monitor from a
Gluster's perspective but not limited to:
- Thin LVM (pool should never get full)
- Number of snapshots
- Quotas (both inodes and total size)
- GeoRep  Status
- Gluster brick status (2  out of 3 down and it's an outage for ' replica
3' volumes)
- Pending Heals
- Errors in Gluster brick logs can indicate FS issues
-  Errors  in other  Gluster  logs


As for the resources used please look at
https://docs.gluster.org/en/latest/Administrator%20Guide/Monitoring%20Workload/
it has helped me quite a bit.

If you find out about the healing process and how to monitor it , please
let me know.


Regards,

Adrian Quintero

How did you deploy it ? - git clone, ./gstatus.py, and python gstatus.py
install then gstatus

What is your gluster version ? Latest stable to Debian Buster (v8)

You got a problem with your gstatus.
How did you deploy it ? 
What is your gluster version ?Mine is working quite fine with 7.7

Re: [Gluster-users] Monitoring tools for GlusterFS

[Strahil Nikolov]

Hi Gilberto,

I just tested latest master branch on CentOS8 -> total failure (both python2 
and python3).

I have opened a github issue at https://github.com/gluster/gstatus/issues/30 

I guess, you can add details for OS, packages and gluster version (maybe a 
traceback also).


The more interesing part is that the old zip I got is working on CentOS8 (with 
python2.7) without issues:


[root@glustera gstatus-master]# python2 gstatus.py  
 
Product: Community  Capacity:  22.00 GiB(raw bricks)
 Status: HEALTHY  520.00 MiB(raw used)
  Glusterfs: 8.0    6.00 GiB(usable from volumes)
 OverCommit: No    Snapshots:   0


If you wish, I can try to upload it somewhere for you.

Best Regards,
Strahil Nikolov

Hello Gilberto. I just made a 1.0.0 release.
gstatus binary is available to download from (requires python >= 3.6)
https://github.com/gluster/gstatus/releases/tag/v1.0.0

You can find the complete documentation here:
https://github.com/gluster/gstatus/blob/master/README

Follow the below steps for a quick method to test it out:

# curl -LO
https://github.com/gluster/gstatus/releases/download/v1.0.0/gstatus

# chmod +x gstatus

# ./gstatus -a
# ./gstatus --help

If you like what you see. You can move it to /usr/local/bin

Would like to hear your feedback. Any feature requests/bugs/PRs are welcome.

I couldn't make it work  on C8...
Maybe I was cloning the wrong branch.

I have commented on the issue:
https://github.com/gluster/gstatus/issues/30#issuecomment-673238987
These are the steps:

 $ git clone https://github.com/gluster/gstatus.git
 $ cd gstatus
 $ VERSION=1.0.0 make gen-version
 # python3 setup.py install

make gen-version will create version.py

Thanks,

Hi
Could you improve the output to show "Possibly undergoing heal" as well?
gluster vol heal VMS info
Brick gluster01:/DATA/vms
Status: Connected
Number of entries: 0

Brick gluster02:/DATA/vms
/images/100/vm-100-disk-0.raw - Possibly undergoing heal

Thanks

We plan to add heal count. For example:

Self-Heal: 456 pending files.

Or something similar. If we list files, and if the number of files is high
it takes a long time and fills the screen making it quite cumbersome.

Yes! I see!
For many small files is complicated...
Here I am generally using 2 or 3 large files (VM disk images!)...
I think this could be at least some progress bar or percent about the
healing process... Some ETA, or similar...
Otherwise the tool is nice and promising...
Thanks anyway.

Usually sharding is used for that purpose. Each shard is of a fixed size.

Gilberto, the release 1.0.2 (
https://github.com/gluster/gstatus/releases/tag/v1.0.2) has included
self-heal status.
The output looks like this:

root@master-node:/home/sac/work/gstatus# gstatus


Cluster:

 Status: Healthy GlusterFS: 9dev

 Nodes: 3/3  Volumes: 1/1


Volumes:

  snap-1   Replicate  Started (UP) - 2/2
Bricks Up

  Capacity: (9.43%
used) 4.00 GiB/40.00 GiB (used/total)

  Self-Heal:


slave-1:/mnt/brick1/snapr1/r11
(13 File(s) to heal).

  Snapshots: 2

  Quota: On

Hope that helps.

Re: [Gluster-users] Monitoring tools for GlusterFS

[Gilberto Nunes]

Hi Sachidananda!
I am trying to use the latest release of gstatus, but when I cut off one of
the nodes, I get timeout...

gluster vol heal VMS info
Brick glusterfs01:/DATA/vms
Status: Transport endpoint is not connected
Number of entries: -

Brick glusterfs02:/DATA/vms
/images/100/vm-100-disk-0.qcow2
Status: Connected
Number of entries: 1

proxmox02:~# gstatus -a
Error : Request timed out


gluster vol heal VMS info works but gstatus -a gets me timeout.

Any suggestions?

Thanks

I tried to reproduce, but couldn't. How did you cut off the node? I killed
all the gluster processes on one of the nodes and I see this.
You can see one of the bricks is shown as offline. And nodes are 2/3. Can
you please tell me the steps to reproduce the issue.

Re: [Gluster-users] Monitoring tools for GlusterFS

The output currently has some whitespace issues.

1. The space shift under Cluster is different than under Volumes, making
the output look a bit inconsistent.
2. Can you please fix the tabulation for when volume names are varying in
length? This output is shifted and looks messy as a result for me.

Cluster:
 Status: Healthy GlusterFS: 7.7
 Nodes: 4/4  Volumes: 3/3

Volumes:

Artem, since the volume names vary for longer volumes the column number
increases and users have to scroll to right.
To overcome this, I have decided to print the volume name in a row by
itself.  PR: https://github.com/gluster/gstatus/pull/44 fixes the issue.

The output looks like this:

root@master-node:/home/sac/work/gstatus# gstatus


Cluster:

 Status: Healthy GlusterFS: 9dev

 Nodes: 3/3  Volumes: 2/2


Volumes:


snap-1

GiB (used/total)

Another small tweak: in your README, you have this:
"curl -LO v1.0.3 gstatus (download)
"
This makes it impossible to just easily copy paste. You should just put the
link in there, and wrap in code formatting blocks.

Sincerely,
Artem

Ack. PR: https://github.com/gluster/gstatus/pull/48 should fix the  issue.

Great, thanks. Thoughts on distributing updates via various repos for
package managers? For example, I'd love to be able to update it via zypper
on OpenSUSE.

Artem, I'm not thinking of creating packages deb/rpm/pkg. Will be glad to
help if any volunteers want to create packages.
