IP SLAs
by Robert Williams 05 Jun '13

05 Jun '13

Hi guys, I’ve just noticed that Observium is showing up Cisco IP SLA targets (didn’t know the feature was there!) – however it doesn’t actually log any values. All the entries IDs and targets are in there (correctly) though: [cid:image003.png@01CE61C9.7B3A9280] It would be cool if they worked (now I’ve spotted it!). They are all recording NaN so I’m not sure if there is simply something not setup correctly on the Cisco side in order for Observium to be able to read it; or maybe if there a ‘supported’ setup of the IPSLA entries on the Cisco I’m meant to follow? The existing config for them is pretty uninteresting: ip sla 139 icmp-echo 10.0.5.139 frequency 10 ip sla schedule 139 life forever start-time now ip sla reaction-configuration 139 react timeout threshold-type immediate action-type trapOnly If a debug would help then I’ll post one, but first I wanted to check if it’s just not fully supported yet (or a known issue). Just curious as I’ve only just noticed it, but it’s probably been there forever ☺ Cheers! Robert Williams Custodian Data Centre Email: Robert(a)CustodianDC.com http://www.CustodianDC.com

High latency poller performance
by Adam Armstrong 05 Jun '13

05 Jun '13

Hi All, I've been testing some improvements to the Poller when deployed in high latency situations (polling hosts on different continents, for example). It involved some SNMP tweaks to pull more OIDs per round-trip, but has varying support in different OSes, so we're making it a hardcoded per-OS attribute. It seems to work particularly well on Cisco IOS, IOS-XR and Arista devices. http://alpha.memetic.org/~adama/snaps/fwy8vmmvii.png Shows the performance gains on a selection of Cisco IOS devices. I'll be committing the changes later today, disabled as default. If anyone wants to test them for us before we enable them as default, give us a shout. adam.

Eigrp was committed by mistake a while back. One day it might get finished, time permitting :-) Rob VanHooren <rob_vanhooren(a)mac.com> wrote: >_______________________________________________ >observium mailing list >observium(a)observium.org >http://postman.memetic.org/cgi-bin/mailman/listinfo/observium

Observium Integration with Munin
by Scott A. Davis 05 Jun '13

05 Jun '13

Hello! First of all, thanks for a great monitoring tool! Second, apologies in advance if my topic has been covered elsewhere. I scanned the mailing list and documentation but did not find what I need. I have Observium and Munin functioning separately on the sane node. I would like to import some of the graphs that Munin has created into Observium. I am not exactly sure how to even start that project. - Is there a simple way to do it? - Are there step-by-step instructions that a semi-novice can follow? Thanks in advance! [SD]

LDAP authentication changes
by Tom Laermans 04 Jun '13

04 Jun '13

Hi everyone, I've made some modifications to the LDAP auth module; if you SVN up to r4114 or higher, please check if your LDAP auth is still working if you are using it. As far as I know (and on my test system), all defaults are sensible and should work just as before without changing anything, however some new features appeared, specifically to support active directory. An example config for AD is on the wiki. Nested groups don't work yet, I will hopefully get around to that soon. Thanks, Tom

Hi all, I would like to hide some unused ports on some device. I see the filters configuration "$config['bad_if'] = array" but if I correctly understand this filter is apply to all devices. Is there a way to do different filter for different device ? BR Pedro

ASR9k users?
by Robert Williams 03 Jun '13

03 Jun '13

Hi, Just curious if anyone is currently using Observium to monitor any Cisco ASR9k based devices? I can see that it has correctly identified all the various hardware modules, line cards and temperature sensors etc. but isn’t graphing things like temperatures or light levels like it does for our Cat6K workforce. Since this is the first ASR device I’ve tried polling on Observium I’m not sure if it’s just not fully supported or if we have some SNMP restrictions on the Cisco which are preventing it from getting what it needs. Any feedback or other experiences are welcome! Cheers all, Robert Williams Custodian Data Centre Email: Robert(a)CustodianDC.com http://www.CustodianDC.com

Memcached updates
by Britt Treece 03 Jun '13

03 Jun '13

Starting to use Memcached and found some of the current Memcached bits in Observium not working optimally. I wrote a new unix-agent script using python rather than PHP. The previous script relied on PECL memcached but didn't do anything for installations using PECL memcache. After a bunch of trial and error I determined that it was easiest to write the script in Python which requires the python-memcached library and is readily available on different OS types and versions. I also modified the applications/memcached.inc.php and polling/unix-agent.inc.php to accommodate the new script. They will also accurately separate different instances of memcached running on the same server as reported by the script. I'm still trying to work out a couple things. The main thing is when you enable Memcached as an application for a device Observium automatically creates an entry in the database but the instance is NULL. When the unix-agent reports on the Memcached instance(s) running on the server new entries get created in the database for each instance and the app with the NULL app_instance never gets used. I've been manually removing it from the database. If possible I would like to work it out so that it doesn't get created automatically. If that's not possible I was going to look into updating that entry with the first real instance reported by the agent. Also wanting to get the Apps tab for the Device to better identify each instance and maybe work on some additional metrics reporting for Memcached specific stats. Patch attached, let me know if it is acceptable or not... Britt Treece

Observium is designed for use in a service provider environment with a main design assumption being that one does not necessarily know what one wants to monitor until the data is needed. We purposefully make it difficult to delete or obscure port information, because that fits our requirements. Adam. Jason Lixfeld <jason(a)lixfeld.ca> wrote: >Why do you say that, Adam?
