Cisco OTV

[adaniels21487]

Implements the CISCO-OTV-MIB to retrieve OTV counters from Cisco devices.
This collects information on the configured Overlays and Adjacencies

Statistics are collected for the amount of VLAN's on each overlay and the amount of MAC addresses available over each OTV endpoint.
OTV alerts are collected and generated if the appropriate alerting rules exist.

Data is displayed under routing at both the global and device level.

Includes function snmpwalk_array_num, which performs a numeric SNMPWalk and returns an array containing $count indexes
One Index:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27.18']['655360'] = 0
Two Indexes:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27']['18']['655360'] = 0
And so on...

Have a play and let me know what you think.

Thanks,
Aaron

👍 from me again.

Although the same comment about uppercase variables as per the other PR.

rrd updates seem to fail:

found extra data on update argument: U:0:57

So graphs don't show any data. This is via rrdcached.

Hi @laf,
Thats not cool. Can you please unicast me the debug poller output for this module (lists@daniels.id.au).

Thanks,
Aaron

Hi @laf,
I have pushed the lower case variable commit as well as adding some new debugging code.
Please send me the output of this and I will take a look.

Thanks,
Aaron

Updated gists, hadn't pulled in your changes :/

[laf]

Gentle nudge :)

[adaniels21487]

Hi @laf,
Sorry mate, I assumed that not pulling in my changes was the source of the problem..

Taking a look at the Gists, things look ok.
Discovery is creating the components, Polling is finding data.

The RRD lines look fine:

    VLAN Count: 8
[RRD Disabled]RRD[update ././HOSTNAME/cisco-otv-Overlay0-vlan.rrd N:8 --daemon 192.168.100.154:42217]

    MAC Count: 0
[RRD Disabled]RRD[update ././HOSTNAME/cisco-otv-FOUND-mac.rrd N:0 --daemon 192.168.100.154:42217]

    MAC Count: 48
[RRD Disabled]RRD[update ././HOSTNAME/cisco-otv-FOUND-mac.rrd N:48 --daemon 192.168.100.154:42217]

    MAC Count: 55
[RRD Disabled]RRD[update ././HOSTNAME/cisco-otv-FOUND-mac.rrd N:55 --daemon 192.168.100.154:42217]

I cant see the message you mentioned in the logs, does this only happen without -r ?

[laf]

No we get that on rrdcached logs. I'll take another look next week when I'm back in work.

Thanks for getting back to me though.

[laf]

I have no idea wtf was going on when I first tried - graphs are working and did on that same day. I blame rrdcached :)

[laf]

Thanks for this pr @adaniels21487. Appreciate the help and support.

[adaniels21487]

no worries @laf, happy to help.
