Adding more Nagions plugins
by Brad Bendy 19 Feb '24

19 Feb '24

I went ahead and added another plugin to the /usr/lib/nagios/plugins directory where all the other working plugins are. When I go to add a probe it doesn't show up in the drop down box. Is there something that has to be ran to look for new plugins? Permissions/use/group are the same as the other plugins that work. Thanks

dark ui image legend legibility
by Wolf Noble 16 Feb '24

16 Feb '24

Howdy, all! is there some voodoo necessary to coerce observium to generate graphs with textual legends that aren't black when dark mode is active? it's kinda hard to view black text on dark blue backgrounds :) I don't see an obvious knob for this, but it's entirely possible I'm just missing the "legend text color" or "make graph text legible in dark mode" or "learn to read" button somewhere :) [= The contents of this message have been written, read, processed, erased, sorted, sniffed, compressed, rewritten, misspelled, overcompensated, lost, found, and most importantly delivered entirely with recycled electrons =]

Syslog repetitive alerts
by joston.gatt＠hudson.com.mt 16 Feb '24

16 Feb '24

Is it possible to suppress repetitive syslog alerts? if yes how can I do this? The issue is I have a particular site which has an issue with one of the internet connections, it keeps disconnecting and reconnecting every 2 minutes. A syslog event is logged each time and I am getting an email alert for each log.

Upgrading O/S of Observium Server - Debian 10 to 11 (or 12)
by Andy Hartwell 15 Feb '24

15 Feb '24

Advice please ! 😊 I have a server which has been running Observium well for some time. Although upgrading the Observium build is easy enough following the instructions at Updating - Observium<https://docs.observium.org/updating/#upgrading-the-subscription-edition-to-…> this obviously does not update the O/S itself. I had a try at upgrading following online instructions yesterday but after he upgrade was complete the Observium web interface would not display – I just got a page of text which I assumed to be PHP script being displayed rather than “running”. Does anyone have any idiot proof (ie aimed at Linux novice) guidance to upgrade the OS without breaking Observium ? Luckily I had taken a snapshot of the VM so could roll back without any drama. Thanks, Andy Hartwell

sysLocation gets rewritten
by Martin 13 Feb '24

13 Feb '24

Hello, I am experiencing something I don't understand. During polling of a host the syslocation -which is returned correctly by snmp- gets changed into another location (which is an old location before moving from "Address B" to "Address A"). $ /usr/bin/snmpget -v3 -l 'authPriv' -n '' -x 'AES' -X 'passwd' -a 'SHA' -A 'passwd' -u 'username' -Pud -Ih -OQUs --hexOutputLength=0 -m SNMPv2-MIB -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'HostName':'161' sysUpTime.0 sysLocation.0 sysUpTime.0 = 0:8:31:49.72 sysLocation.0 = "Address A" This is the correct address returned. A few lines lower in my debugging output I see: sysLocation rewritten from 'Address A' to 'Address B' by DB override. Even if I change the address in mysql to the correct address the polling process keeps changing it to the old address. MariaDB [observium]> select hostname, location from devices where device_id=9811; +-------------------------+--------------+ | hostname | location | +-------------------------+--------------+ | HostName | Address B | +-------------------------+--------------+ My questions: - Why is this happening? - How can I prevent this from happening? - Where does the old address come from? I hope someone can shed some light on this strange issue... Thanks, Martin

Microsoft Teams Notification Template
by Lars Joergensen 12 Feb '24

Hey Seems the template for notification on MS Teams is broken (see below). I'm trying to make my own, but would like to know which of the templates in includes/templates it is based on, so I know where to start.

alert checker for specific ping probes
by Tony Guadagno 07 Feb '24

07 Feb '24

Hi, I have a bunch of ping probes and I would like to write an alert for some (but not all). Since the hostname is the same for all, how can I differentiate between them in an alert checker...for example, I want to alert on this: [cid:image001.jpg@01DA551D.A2E6D3E0] But not this: [cid:image002.jpg@01DA551D.A2E6D3E0] thanks Tony Guadagno O +1 585 577 1003 C +1 585 703 6700 E tonyg(a)guadagnoconsulting.com<mailto:tonyg@guadagnoconsulting.com> [cid:image001.jpg@01D84DD6.FC9912E0]

Remove Switch Access interfaces from polling
by Massimo Cirulli 07 Feb '24

07 Feb '24

Hi All, I'm a newbie user of Observium. I need to clear the polling in order to not have the access port checked on the campus that we monitored. We have about 50k access interfaces splitted on Cisco and HP Aruba stack. I understand that i declare in config.php the bad iface but they have different name: Cisco -> Gi1/0/1 HP Aruba -> 45 My goal is: only the uplink will be checked. How can i use the config for access layer Cisco and Aruba stack (iface range) ? $config['bad_if'][] = " Gi1/0/1 ->?"; $config['bad_if'][] = "1->"; Thanx in advance for your support Massimo
