Nagios smartmon stops working after python upgrade

2 Comments / Nagios / By /

This just in:

$ /usr/local/bin/sudo /usr/local/libexec/nagios/check_smartmon -d /dev/da0
Traceback (most recent call last):
  File "/usr/local/libexec/nagios/check_smartmon", line 307, in <module>
    (healthStatus, temperature) = parseOutput(healthStatusOutput, temperatureOutput, devtype)
  File "/usr/local/libexec/nagios/check_smartmon", line 216, in parseOutput
    vprint(3, "Health status: %s" % healthStatus)
UnboundLocalError: local variable 'healthStatus' referenced before assignment

But I can’t fix that now. I’m off to the Oscars party.

    Here is an ata device:

    $ sudo /usr/local/sbin/smartctl -H /dev/ad0 
smartctl 6.2 2013-07-26 r3841 [FreeBSD 9.2-RELEASE-p3 amd64] (local build)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED

    Here is the same type of device, presented as a scsi device:

    $ sudo /usr/local/sbin/smartctl -H /dev/da0
smartctl 6.2 2013-07-26 r3841 [FreeBSD 9.2-RELEASE-p3 amd64] (local build)

=== START OF READ SMART DATA SECTION ===
SMART STATUS RETURN: incomplete response, ATA output registers missing
SMART overall-health self-assessment test result: PASSED
Warning: This result is based on an Attribute check.

    Here is the patch which ignores that incomplete response line:
