RAM needed per number of ports
by Arnoldo Vidal Bravo 27 May '25

27 May '25

To update a server for Observium, we want to estimate the amount of RAM needed based on the number of ports. We have 30,000 ports on 650 devices. 28,000 ports are ignored (user only). We're interested in monitoring 2,000 ports. Can you confirm if 8GB of RAM will be sufficient? Or should we consider more RAM? -- Saluda cordialmente

New Implementation
by rudym88＠hotmail.com 21 May '25

21 May '25

Good day, We are considering purchasing Observium, either the Professional or Enterprise, and would like to know if it will meet our specific requirements. 1 - Will we be able to monitor the following vendors: Sonicwall, APC, Granstream (switches, PBX), Ubiquity, Netgear switches, Dell, servers, and workstations? 2 - Due to some required pro-activity monitoring, we use syslog. Can Observium handle syslog. (e.g. we need to be notified as soon as a port goes down instead of waiting for the polling cycle) 3 - We need to have the system send an alert to our ticketing system. Does Odservium send one alert per email, or does it group all the alerts into a single email? Looking forward to a reply to move forward. Thanks Rudy

I asked a question with my work email and of course forgot to remove my signature. How do I remove all my information? Getting a lot of BOT and sales calls.

Migration went wrong / Windows SNMP Service detection not working
by IT 09 May '25

09 May '25

Hello, i am quite new to the administration of Observium. The old admin is out of reach and gone. I tried the migration process like described. Old Server: Ubuntu 22.04.5 LTS with Observium 25.2.13882 (stable) New Server: Ubuntu 24.04.2 LTS with Observium 25.4.13987 (stable) The Migration seems to be not 100%. Problems: 1. Only 10 of 43 Probes have been migrated 2. After re-adding some check_ping probes I stumbled across the folder /usr/lib/nagios/plugins The folder was empty Checked the old Server; full folder Copied the hole folder to the new Server. Check_ping now possible and working 1. Check_snmp_win is still not possible. Started the old server; still able to check the Windows services How can I check, what's wrong with my new Server and the Windows Service Check? GVB

Is there a plan for Observium to support Proxmox? This also includes the display of individual VMs, as is done with VMware. Best Regards, Marco

Wrapper discovery misbehaving
by Milton Ngan 18 Apr '25

18 Apr '25

I am running multiple pollers, and we just noticed that the discovery of new hosts is not doing what we would expect when trying to partition the workload. Instead of doing a third of the new hosts, it does a third of all the hosts, essentially doing a full discovery, which is causing some our PDU’s to get overloaded, since they are being hit by 3 parallel discoveries and also possibly a poll at the same time. /opt/observium/observium-wrapper discovery --host new -i 3 -n 0 If I remove the -i and -n options, then it does what I would expect, although it is not distributed, which isn’t a problem because the number of new devices should be pretty small. So the --host and the -i and -n options appear to be mutually exclusive, which isn’t stated in the help at all.

Netstat Missing
by observium＠lsl-technology.com 17 Apr '25

17 Apr '25

If I look at the list of devices, when I select any of the network devices and select Graphs, the dropdown menu has an item called NETSTATS ... This item is not available if I select a VM or a server and select Graphs. How do I view network stats on any of my server devices, be them VM or physical server? Thanks Lawrence

Send email alerts only for some checkers, not all of them
by Silvio del Val Hinojal 11 Apr '25

11 Apr '25

Hello, First of all, congratulations for your great product :) I have been searching this the forum but I can't find an answer for this :( We are currently using Observium Pro v18.10.9500. I'm trying to configure emailing so that I would like to be notified on some alerts generated by some of the alert checkers but not all of them, but I'm not able to do it :( Currently I'm receiving email alerts from all of my checkers. This is my current "config.php": // Set up a default alerter (email to a single address) // $config['email']['default'] = ""; // $config['email']['default_only'] = TRUE; $config['email']['from'] = "< I omit this part, this is our current email, this is working >"; $config['email']['smtp_host'] = "< I omit, our SMTP email server >"; $config['email']['backend'] = "smtp"; // Mail backend. Allowed: "mail" (PHP's built-in), "sendmail", "smtp". $config['email']['smtp_timeout'] = 30; We have only one contact with our destination email address and we have associated only 4 of 7 defined alert checkers, but we are currently receiving email notifications from all of them.
