Device first discovery date
by Attila Nagy 09 Oct '25

09 Oct '25

Hi Everyone! Is there a way to find out the date of the "first contact" with a device from Observium? I mean for example the date when the first discovery was run on a specific device, or something like this? (Currently the device's event log runs out after half a year.) Any ideas? Regards, Tylla

phantom sensor and status alerts
by Tony Guadagno 30 May '25

Hi, I am running pro version [cid:image001.png@01DBD0A7.1BDDACF0] today, I saw there were a couple of status alerts and a sensor alert...however, when I click on these links, those alerts are not listed, only the warning is listed.... I think this was working in the past....can someone explain why it indicates sensor and status alerts but does not list them anywhere? Thanks in advance [cid:image002.png@01DBD0A7.1BDDACF0]

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

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
