check_ibm_bladecenter.py

Follows a fan failure on one of our BladeCenter in our hospital. I corrected the bug that indicates OK status despite one of the failed fans on both. Since this is a major issue on a BladeCenter, I removed the warning state to go directly to critical.

For that I control the state returned for the fan "blower1state and blower2state and I add in addition a condition for which the fan must have a speed of rotation different from 0%:
and blower1speed != "0% of maximum":

def check_blowers():
" Check blower status "
blowers = getTable("1.3.6.1.4.1.2.3.51.2.2.3")
# This mib only seems to support 2 blowers.
blower1speed = snmpget("1.3.6.1.4.1.2.3.51.2.2.3.1.0")
blower1state = snmpget("1.3.6.1.4.1.2.3.51.2.2.3.10.0")

blower2speed = snmpget("1.3.6.1.4.1.2.3.51.2.2.3.2.0")
blower2state = snmpget("1.3.6.1.4.1.2.3.51.2.2.3.11.0")

add_long( "Blower 1 state=%s speed=%s" % (blower1state,blower1speed) )
add_long( "Blower 2 state=%s speed=%s" % (blower2state,blower2speed) )
add_perfdata("blower1=%s" %(blower1speed.split(None,1)[0] ))
add_perfdata("blower2=%s" %(blower2speed.split(None,1)[0] ))
# Check blower 1
if blower1state == "1" and blower1speed != "0% of maximum":
nagios_status(ok)
add_summary("Ventilateur 1 OK. " )
else:
add_summary("Ventilateur 1 KO. ")
nagios_status(critical)

# Check blower 2
if blower2state == "1" and blower2speed != "0% of maximum":
nagios_status(ok)
add_summary("Ventilateur 2 OK. " )
else:
add_summary("Ventilateur 2 KO. ")
nagios_status(critical)

Thank you for plugin!
I allowed myself to make some improvements.

Thanks for the nice plugin. A few tweaks would be great:
1. Use standard Nagios warning/critical thresholds
a. ex: check_ibm_bladecenter -H mychassisIP -C public -m powermodules -w 4: -c 3:
b. The above check returns an error, and even when a single digit (i.e. -c 4) is supplied, it doesn't seem to affect the status. In my environment, 2 power supplies are redundant so I would like to get a warning if 1 drops (4 p/s = OK, 3 p/s = WARNING, 2 p/s = CRITICAL)
2. -m blowers returns first blower twice in status but shows correctly in perfdata
a. OK - Blower1 OK. Blower1 OK. | blower1=60% blower2=61%

Nothing to blame, works fine with our Blade-Center
and all the features are available.
good

The checks work well, however the blower one doesn't report correctly into Nagios. I've not had a chance to test all of the others.

I was doing some troubleshooting on one of the blowers and as a result I had to power it off. The --mode blowers came back with the following...

OK - Blower1 OK. Blower1 OK. | blower1=81% blower2=0%

Blower 1 state=1 speed=81% of maximum
Blower 2 state=1 speed=0% of maximum

...however in Nagios everything appears as OK.

The temperature check works well with the warning and critical values.

A tweak to sort out the above would be amazing!
