Observium Polling via SSH
by Cailean Keniston 28 Dec '16

28 Dec '16

Hi All, I have an environment that uses Observium but a lot of our systems that we need to keep track of and poll are having ICMP echo requests turned off which makes polling a little difficult. So after making backup copies of the files I am starting to make a module that polls via SSH. Currently it's in the "works under conditions X" stage and I had to bake it into some of the includes code (hence the copies). I guess my main question is this something anyone is interested in being submitted as an option? I'm currently working on the ability to make it more of an automated process, and set up a flag that toggles whether the poller works with ping or ssh. But, if this is so niche that it's not really something cares about then cool, but I thought I would ask in case it could be a useful feature to add for others? And, if it is something that might seem useful then if there's a preferred method of adding it over putting it directly into the existing code I'm perfectly willing to go that route instead so I'm not messing with anyone's flow. Thanks, Cailean

Error
by Jason Vanlandingham 27 Dec '16

27 Dec '16

First time I've seen this. It showed up once today, and once on 24 Nov. I would expect an error like this to happen every time this ran or not at all. What is this? Executable '/opt/observium/poller-wrapper.py' doesn't belong to any package and ProcessUnpackaged is set to 'no'

Observium: sensor class question
by David Schrok 27 Dec '16

27 Dec '16

Hi all, Question: Is there a way to map a sensor to another sensor class? Currently I have a sensor that shows up as a temperature sensor which in fact is a humidity sensor. Would be great if I can map the sensor or OID value as humidity. With kind regards, David Disclaimer ( http://www.avans.nl/over-avans/e-mail-disclaimer )

Re: [Observium] Updates to CentOS7 instructions?

Had problems with this a few months back too.

atime necessary?
by William Bauer 24 Dec '16

24 Dec '16

Being a BSD and Solaris guy (ZFS for years!), I brought up my new Observium installation putting mariadb on one ZFS mirror, and Observium on another. One thing that can improve performance is by disabling the atime attribute on a filesystem. Does Observium or mysql/mariadb care about this, or can I safely disable it on either or both filesystems? It won't impact the normal timestamps, just the tracking of the last access time of individual files. Thanks again.

Re: [Observium] Moving Observium
by Cody Cook 22 Dec '16

https://www.digitalocean.com/community/tutorials/how-to- migrate-a-mysql-database-between-two-servers That creates and migrates a database. You will also need to add and give permissions for a user on your new MySQL server. The installation instructions should explain how that's done since it is the same commands. Then update the config file for Observium to match your new setup. This is probably a basic skill you should know outside of using Observium.

Updates to CentOS7 instructions?
by William Bauer 22 Dec '16

22 Dec '16

I'm replacing a poorly performing VM running CentOS6 with a real computer running CentOS7. The two commands (listed below) early on in the CentOS7 instructions appear to be invalid. I'm not super Linux literate as I know more of the BSD and Solaris worlds. Are there replacement sources for these? Here are the ones currently failing (I've tried no more of the instructions).

Wireless Networks
by Stef Renders 20 Dec '16

20 Dec '16

Hi All, We recently started adding customer's wireless environments in our Observium installation. I'm not sure whether this was ever available, but I can tell that observium is discovering my SSID's since I can see them in the database, however, I don't seem to find any reference to them in the interface. Anyone has an idea how far this was ever implemented ? Our customer is using Ruckus. And it seems only the wifi_wlans table is being populated: Kind regards

suppress tiles on front page
by Vater, Wolfgang 20 Dec '16

20 Dec '16

Hi there, I created alerts for port errors and discards to be notified if there are more than 25. But on my front page I get a tile for each port with port errors, even if it is only 1 error. Is this customizable? I would like to be able to suppress this for ports where I know this happens but can't do anything about it (because someone else doesn't want to fix their device), or raise the threshold so something higher than 1?

2 x feature request : Avoiding multiple entries for same devices & subgroups
by Jesper Frank Nemholt 20 Dec '16

20 Dec '16

Hi! 1. Especially with autodiscovery I get the same devices created multiple times as the hostname differ and Observium don't seem to always properly identify that the sysName and SNMP ID is the same. What I end up with is either the same device being in there twice. I also have this issue on some solutions using clustering and internal DNS & DHCP so nodes can have multiple IPs and DNS names and change these over time so the only constant is SNMP sysName and SNMP ID. What I am doing now as a workaround is to disable all but one entry per device when I see these duplicates, but it would be great to either have a better check to avoid this from the very beginning, or potentially to have something like what is present for syslog host mapping to allow a N to 1 mapping of devices like : $config['device']['host_map']['foo.bar'] = 'bar.foo'; // device hostname/sysname $config['device']['host_map']['foo.bar'] = 'foo.foo'; // device hostname/sysname With something like this in config.php I could then delete the duplicate entries and they would not be auto discovered again, and I'd avoid having to disable them. 2. The other thing is that it would be great if it was possible to create subgroups for devices, ports and custom OIDs. When having lots of groups for different areas or lots of custom OIDs it quickly gets crowded and having the ability to organize these in a group hierachy would be great, similar to how locations are grouped by country when using geo-coding. /Jesper
