SNMP Changes and rediscovery
by Derek 04 Aug '16

04 Aug '16

I've recently switched several devices off of SNMP v2c to v3, and I've updated my config.php with all the v3 parameters, and I'm wondering if there's a way for force a re-discovery using the new info without having to go into each individual device and enter in all the new SNMP information? I didn't see any flags in for discovery.php that would force it.

db.log
by Charlie Bell 03 Aug '16

03 Aug '16

Hi, I've had a small Observium (c. 5500 ports) running for a couple of years (SVN version). Have configured housekeeping, which is fab and has kept things from getting out of hand. However, noticed /opt/observium/logs/db.log is a 5.6GB file... Can I clean this up? Should I be running a cron cleanup task on this?

False Alert (snmp)
by Laurence Mayer 02 Aug '16

02 Aug '16

Hello, Today for no known reason we received the below alert in the "Recent Events" (and via email), everything on the switch appears to have been ok and could not find any issue that should have caused this alert. 6h 36m 15scisco10g1 cisco10g1 Device status changed to Up 6h 36m 16scisco10g1 cisco10g1 Device status changed to Down (snmp) Is there a timeout that may have caused this that i can increase to avoid false/positives? Thanks Laurence

Ports Shown As Down
by Laurence Mayer 01 Aug '16

01 Aug '16

Hi, After a power outage, the front page (and Status Warnings and Notifications) is showing a Cisco device's Ports as Down, of all ports that have NO devices (workstations) connected. The alert I have defined (taken from the example) Port is enabled, but operationally down ifAdminStatus equals up ifOperStatus notequals up * ifType equals ethernetCsmacd I have run the poller.php multiple times with no success. Is there a default amount of time until these warnings will be cleared, is there a process that can be run to clear these alerts? Thanks Laurence

Email Alerts Not Working
by Laurence Mayer 01 Aug '16

01 Aug '16

Hi, I have recently installed Observium and updated to the stable version. I have successfully configured a number of alerts, however despite the alerts being generated (I see them via the web gui) I do not receive them to email. Using test_alert.php -a 1 (see below) I am able to receive email, however the test email looks a little empty from what I would expect. I receive the following error, see below for the debug. *ERROR[Error in query: (Incorrect table name '') 1103]* Any guidance will be appreciated.

Observium poller/discovery module descriptions
by Andrew.Jones＠kiewit.com 01 Aug '16

01 Aug '16

I have searched your webpage and FAQ and can't seem to find answer to my question: Do you guys have a list handy describing what each of the poller and discovery modules do exactly? $config['poller_modules']['system'] = 1; $config['discovery_modules']['os'] = 1; I am working on a new deployment of Observium and am trying to optimize it and configure some custom requirements and it would be helpful having some additional information regarding each module. Thank you!

Howdy again. I am looking to add some graphs for squid performance metrics - wondering if there has been any work done on this to get me started or do I need to roll my own? Thanks

Slow poller speeds after migration
by Lyndon Labuschagne 29 Jul '16

29 Jul '16

Hi All I have moved from a VM server to a physical server. as the VM was taking a bit of a pounding, graph dropouts etc The physical server is a dual quad core Xeon, 2.66Ghz with 128GB of RAM and a 32GB ramdisk, and rrdcache I also have 2.5TB or SAS storage in a raid6 config Will all of this my average poller-wrapper time is around 60 to 70 seconds per device if I manually run an snmpwalk a single device takes around 6 seconds I have also disabled the ramdisk, rrdcached etc and I am not seeing much of a difference either way I have around 900 devices and the VM server was way faster, any idea where to start looking for a bottleneck? Regards Lyndon

https://alterslash.org/day/20160728#article-9452929 What about using the mail archive service linked at bottom of summary? Then again I wonder how long that will survive for.
