Check cisco 3750 stack status

This plugin is very helpful monitoring Cisco stacks. However, With the bugs mentioned and no recent updates I decided to rewrite this in python for my environment. I need to add support for SNMP version 2 but, if your still using version 1 you may check out my plugin.

https://github.com/wershlak/nagios_plugins/blob/master/check_cisco_stack.py

I'm very happy with this script! Wonderfull.

However, you are missing a very important state! 'removed'

We had a power outage and the script broke due to this and did not report a valid response

/usr/lib64/nagios/plugins/check_snmp_cisco_stack: Use of uninitialized value in concatenation (.) or string at (eval 1) line 150,.

my %STACK_STATES = (
'1' => 'waiting',
'2' => 'progressing',
'3' => 'added',
'4' => 'ready',
'5' => 'sdmMismatch',
'6' => 'verMismatch',
'7' => 'featureMismatch',
'8' => 'newMasterInit',
'9' => 'provisioned',
'10' => 'invalid',
'11' => 'Removed',
);


Apart from that, thank you very much!

Good script!

However I would like to see more checks in this.. for example temp cpu etc of individual devices in the stack, is that possible?

The OID for stack state (1.3.6.1.4.1.9.9.500.1.2.1.1.6) can return Integer:11 which does not have appropriate entry in %STACK_STATES.
According to

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=1.3.6.1.4.1.9.9.500.1.2.1.1.6&translate=Translate&submitValue=SUBMIT

after line 45, one more line should be added:

'11' => 'removed'

With this change (and the one pointed out by tt-ts), it works great. Thanks!

To get a 3650 Stack working you have to replace the line...

my $id = ( $$result{$key} * 1000 ) + 1;

... with ...

my @key_split = split('.', $key);
my $id = pop @key_split;


3750 will work with this change as well.

First of all: thanks for that good piece of code

but in line number 142 there is a small bug

if ( $members{$member} == 4 or 9 )

this condition always turns to true (at least for me)

I guess it should be:

if ( $members{$member} == 4 or $members{$member} == 9 )

i tested it with a 2960s stack and it seems to work perfectly
