A couple time per hour I'm receiving this error message:

Traceback (most recent call last):
  File "/opt/scripts/zabbix-glusterfs/gstatus_discovery.py", line 7, in <module>
    gstatus_output = subprocess.check_output('gstatus -a -o json ', shell=True).decode()
  File "/usr/lib64/python3.4/subprocess.py", line 617, in check_output
    raise CalledProcessError(retcode, process.args, output=output)
subprocess.CalledProcessError: Command 'gstatus -a -o json ' returned non-zero exit status 16

Anyone else experiencing it?

gstatus --version
gstatus 1.0.4
gstatus output result - correct.
When run gstatus_discovery.py - JSONDecodeError.
./gstatus_discovery.py

Third user parameter in documentation is incorrect. Instead of:

UserParameter=gluster_volume_info,sudo /path/gstatus_discovery.py

it should be:

UserParameter=gluster_volume_name.discovery,sudo /path/gstatus_discovery.py

Hello,

The value usable_capacity returned by gstatus(1) is not the total space available but the free space remaining. Example on my cluster with my patched version of gstatus_discovery.py[1]:

# gstatus_discovery.py -k used_capacity
81097048064
# gstatus_discovery.py -k usable_capacity
37565235200

The sum of these numbers roughly equals raw_capacity.

The current item “Gluster Storage Total Size” should be renamed “Gluster Storage Free Size” and a new item of the Calculated type named “Gluster Storage Total Size” should be created with the following formula:

gluster_storage_info["used_capacity"] + gluster_storage_info["usable_capacity"]

Of course “Gluster Storage % Free Space” should adapted too.

[1]: A pull-request should come in the following days or weeks.
