[Nagiosplug-devel] Plugin Wrapper written in python

The other day I wrote a sort of wrapper that uses Nagios' check_icmp plugin
to monitor several nodes on our network. If any one of the nodes down it
returns a value of 1 (WARNING), if two or more nodes go down it returns a
value of 2 (CRITICAL).
Unfortunately, even if it is critical it still shows up as Ok...even though
I know it is returning a value of 2. The plugin is written in python.
#!/usr/bin/env python
import os
import subprocess
home="/usr/lib/nagios/plugins"
def checkNodes():
up = 0
aProblemsDetected=0
bProblemsDetected=0
cProblemsDetected=0
status=0
message=" - "
TEST_OK=0
TEST_WARNING=1
TEST_CRITICAL=2
TEST_UKNOWN=3
try:
cloud_alpha_status=subprocess.check_output(home+"/check_icmp -H cloud-alpha
",shell=True)
if "OK" in cloud_alpha_status:
++up
else:
message=message+ "Cloud Bravo does not seem to be
reachable. "
aProblemsDetected=1
except:
message=message+"Node (Cloud-Alpha) is either down or
unreachable. "
aProblemsDetected=1
try:
cloud_bravo_status=subprocess.check_output(home+"/check_icmp -H
cloud-bravo",shell=True)
if "OK" in cloud_bravo_status:
++up
else:
print cloud_bravo_status
message=message+"Cloud Bravo does not seem to be
reachable. "
bProblemsDetected=1
except:
message=message+"Node (Cloud-Bravo) is either down or
unreachable. "
bProblemsDetected=1
try:
cloud_charlie_status=subprocess.check_output(home+"/check_icmp -H
cloud-charlie",shell=True)
if "OK" in cloud_charlie_status:
++up
else:
print cloud_charlie_status
message=message+"Cloud Charlie does not seem to be
reachable. "
cProblemsDetected=1
except:
print "Node (Cloud-Charlie) is either down or unreachable. "
cProblemsDetected=1
if aProblemsDetected+bProblemsDetected+cProblemsDetected==0:
status=TEST_OK
message=message+"CLUSTER IS UP! -- Cloud-Alpha up --
Cloud-Bravo up -- Cloud-Charlie up"
code='OK'
if aProblemsDetected+bProblemsDetected+cProblemsDetected==1:
status=TEST_WARNING
code='WARNING'
message="Errors Detected:"+message
elif aProblemsDetected+bProblemsDetected+cProblemsDetected>1:
status=TEST_CRITICAL
message="Many Errors Detected"+message
code='CRITICAL'
return status,(code+' '+message)
print checkNodes()
