Updating observium system via yum update
by Edvinas Kairys 22 Dec '20

22 Dec '20

Hello, it's been a while I was upgrading the Observium dependencies. Currently we're suing OLD Centos version: CentOS Linux release 7.3.1611 (Core) [image: image.png] What do you think, is it safe to update system via yum update? It would upgrade Centos 7.3 to 7.x and should upgrade Python, Maria DB (from 5.5.56 to 5.5.68) ant other Observium dependencies. After this base update, i would try to manually update MariaDB to 10.x and Python, if yum update will be insufficient. My concern is to not corrupt the system. Could you give some recommendations or i'm too careful and everything should be fine with yum update. ? Thank you:)

Smokeping graphs post migration
by Joey Stanford 19 Dec '20

19 Dec '20

Howdy, I need some help pointing me in the right direction for troubleshooting. I migrated Observium from Ubuntu to Debian and life is good except for smokeping. I have no graphs but… * smokeping is installed * smokeping and observium’s config.php are using the same configuration as the old server * going to [host]cgi-bin/smokeping.cgi shows me all the graphs and they are up to date * going to the tech support page shows me that observium finds the graphs e.g. - Found file ending in ".rrd": router_thorodin_rmham.rrd - Determined to be a local file, for target router_thorodin_rmham - After replacing configured split_char _ by . target is router.thorodin.rmham so at this point I know smokeping is working, the graphs have the right perms to displayed (currently smokeping:observium), and observium can see the rrd file. Unfortunately going to the page I get the dreaded “Error drawing graph”. At the bottom of the smokeping section in tech support I see two items. One is an error for no outgoing latency graph. Any ideas on what else I could look at? RRD for incoming latency found. RRD for outgoing latency not found.

Juniper polling performance tip
by Markus Klock 19 Dec '20

19 Dec '20

Hey guys! Just wanted to share a little tip on how to increase Observium polling performance on juniper boxes. This might be old news for some but I just found it. You can create a filter on junos-device that filters out certain interfaces from SNMP view. https://www.juniper.net/documentation/en_US/junos/topics/task/configuration… I can recommend using: set snmp filter-interfaces all-internal-interfaces set snmp filter-interfaces interfaces "^sxe-.*" This will filter out all useless internal interfaces from polling and discovery by Observium. Especially when you have large juniper switch stacks the total number of internal interfaces are a lot which slows down polling. Filtering them out actually makes a big difference. If you got a lot of juniper gear, try it out and please share the speedup in pollingtime! /Markus

Random few questions
by Simon Smith 15 Dec '20

15 Dec '20

Hi All, I've got a few random questions that probably have simply answers too Ive checked our poller performance logs and its showing ’total time for all devices as 463.46s’ Is this a worry? Should it be under the 300s as the poller is set to run every 5 min? The highest device we have according to the poller performance is a mikrotik hex s router and that takes 30 seconds to poll, again is this normal? Also the poller performance for that device is showing its taking about 15seconds just to poll the ports module but again it only has 5 ports? Kindest Regards Simon - Hestor Ltd

backing up Observium server
by Edvinas Kairys 15 Dec '20

15 Dec '20

Hello, I know that if i want to have a fully backup i need 3 things. 1) Mysql dump 2) copy of config.php 3)and copy of .rrd folder. My question is: Do it's enough to have first two things: MYSQL dump and copy of config.php ? Because old traffic data (.rrd) is not so critical as loosing all the rules/alerts of Observium (and weathermap which is on other directory)
