Error message: Custom check status not changing always OK
I have created the script below to check the available space in my vcenter appliance. I created the files and tested they run using the correct account, the status will not change to CRTITICAL… I have installed the check as a rule in Integrate Nagios plugins using the config as in the screenshot. The output shows as if it is not get processed by check_mk. (screenshot attached). This is the first check I created using python.

import subprocess
overquota = []
multiline = ''
cmd = ["bash", "/opt/omd/sites/mysite/custom/vcenter/get_data.sh"]
proc = subprocess.Popen(cmd, stdout=subprocess.PIPE)
for line in proc.stdout:
data = line.decode("utf-8")
if '/' in data:
columns = (data.replace("%","")).split()
if int(columns[4]) > 5:
overquota.append("Mountpoint " + columns[5] + " is " + columns[4] + "% full")
if len(overquota) > 0:
for i in range(len(overquota)):
multiline = multiline + ('\n' + overquota[i])
print('2 vcenter_space count='+ str(len(overquota)) + ';1;2 Server free space error! ' + multiline)
else:
print('0 vcenter_space count=0;1;2 Server free space normal.')
