Performance
by Morten Guldager 14 Nov '14

14 Nov '14

'Aloha! I'm in the process of evaluating observium for my organisation's needs. We have some instances running already, but my task is to do the evaluation in a more structured way. I have some questions which I will keep in different posts to keep the threads clean. Performance: We are looking at a network currently consisting of 4000 devices with close to 100'000 ports. These devices are well known to observium and a subset of them got auto discovered just fine. But how about performance. Will it require vast amounts of computing power? Also, our network grows quite rapidly, might be 50% bigger 12 months ahead. I found an old thread from July 2013 where Joe Hoh describing a complex multi server setup to scale observium to something approx 2-3 times my current needs. Will I have to go through similar "struggles" to get it working? Or has observium changed much to make it scale different than it did 1.5 year ago? Pointers to information regarding scaling observium are most welcome. -- /Morten %-)

Setting up alerts
by Sanjeev Gupta 13 Nov '14

13 Nov '14

Hi, I am using svn 5973. I am trying to setup an Alert Checker. No matter what I do, I get an error that the alert name must be unique. I have tried strange names in the "Alert Name" field, but everything seems to be taken :-( Leaving the entity field blank, gives me another error. I am trying to setup, to start with, alerting if a port on the upstream router runs at 80%. Please see http://postimg.org/image/ah4h97ly7/ Checking what alerts exist gives me this page: http://postimg.org/image/sl08oy6y1/ I delete them all, and they reappear after a Regenerate. -- Sanjeev Gupta +65 98551208 http://sg.linkedin.com/in/ghane

hddtemp from arch linux workstation PC
by David Ford 13 Nov '14

13 Nov '14

Hello, I wonder if anyone has the local HDDTEMP script working on an Archlinux PC that could help me. It works fine on my server (ubuntu), but I just get intermittent output of 1 disk (sda) and no temp reading at all from the Arch linux PC. It seems to be: if [ $? -eq 0 ] && [ `$nc -zv $hostname $port 2>&1 | awk '{print $5}'` = "open" ] that causes the error and I am not knowledgeable enough to work out a solution. nc localhost 7634 outputs... |/dev/sda|TOSHIBA THNSNH128GBST|30|C||/dev/sdb|ST500DM002-1BD142|32|C||/dev/sdc|Hitachi HDT725050VLA360|38|C| Thank you, Fordy. #!/bin/sh # hddtemp sensor readings # needs hddtemp daemon listening on (at least) localhost # requires netcat to be installed and in the path # (c) 2012, Tom Laermans for Observium hostname="localhost" port=7634 nc=`which nc` if [ $? -eq 0 ] && [ `$nc -zv $hostname $port 2>&1 | awk '{print $5}'` = "open" ] then echo '<<<hddtemp>>>' $nc $hostname $port echo fi

Hello there, how can I disable CISCO-BRIDGE-EXT-MIB from the GUI? This is the Nexus polling killer, but I can't find it in the list of MIBs that I can disable. I'm running rev. 5975 stable Cheers, Marco

Odd devices
by Morten Guldager 13 Nov '14

13 Nov '14

'Aloha! I promised you more questions for use in my evaluation process, here comes the next one: Odd devices: besides the 4000 routers and switches in my previous post, our business does a great deal of video transmissions. This is handled with crazy video codec boxes which sometimes have very limited SNMP capabilities. I face two problems: - it cant be autodiscovered; the MIB simply doesn't that. I have a database describing exactly what we have and how it's configured. - it's covered by NDAs, so I cant event tell you much about it. I would like to graph various parameters in these devices using observium, but I guess I will have to implement these myself. (or hire somebody to sign the NDA and hack something together for me). Also, sometimes the concept needing graphing isn't really bound to a single device, but more a collation of multiple states from multiple devices. I understand that observium isn't really meant to be extensible by the end customer (me) by simply tweaking configuration. I read "It's not as simple as "adding the MIB", actual code needs to be written to support the device and its features. You could learn PHP and familiarise yourself with the Observium codebase and write support for it yourself." as a warning, as i'm nowhere a competent PHP hacker. Think the questions are: - is observium at all the right tool for the job? (a goal is to limit the number of tools the NOC has to learn) - can observium live in an non-auto-discovery world? - can observium handle abstract measurements not bound to a specific device? -- /Morten %-)

No storage graphs and storage module keeps switching to disabled
by Richard Boezerooij 12 Nov '14

12 Nov '14

Hello, Several (virtual) servers (Windows 2008 R2) do not show the storage graphs in Observium. On these servers the poller module keeps switching to disabled. The amount of storage used do show up on these servers. Other servers, same configuration, do show the storage graphs. On these servers the storage poller module do stay enabled. I've checked and restarted the SNMP service locally on these servers. I've updated CorreLog (syslog agent) on the servers to the latest version. Observium is installed on a Ubuntu server. I've updated Observium to 0.14.11.5963. How can I fix this problem?

Hi, I have tried some times ago to change the MySQL server into MariaDB on my Observium server (community), but it seems that is breaking some parts of Observium and doesn't seems to update things. Anybody here have a good experience about moving MySQL to MariaDB with observium ?
