The answer is in the CLI output when you tried adding the device there. ==== # ./add_device.php jr01 home v2c 161 udp Observium CE 18.9.9420 Add Device(s) Try to add jr01: Trying v2c community *** [0] ... No reply on given community *** using v2c. Could not reach jr01 with given SNMP parameters using v2c. Devices failed: 1. ==== Your device is not answering your SNMP queries. I'd start by checking the following: - wrong community string - wrong dns/hosts entry - snmpd on the target not listening/bound correctly for remote v2c queries - local firewall on target device Cheers, Michael > On 8 Sep 2018, at 1:17 pm, Michael <michael(a)smarsz.com> wrote: > > The answer is in the CLI output when you tried adding the device there. > > > ==== > # ./add_device.php jr01 home v2c 161 udp > Observium CE 18.9.9420 > Add Device(s) > > Try to add jr01: > Trying v2c community *** [0] ... > No reply on given community *** using v2c. > Could not reach jr01 with given SNMP parameters using v2c. > Devices failed: 1. > ==== > > > Your device is not answering your SNMP queries.

Devices not being discovered
by Roland Hill 08 Sep '18

08 Sep '18

Hi all, I've been running the CE version of Observium for a few years now, always upgrading as the new releases come out. Earlier this year my server hosting Observium updated to Ubuntu 18.04 and php7x. As previously raised on list, this was incompatible with the previous CE version. No problem, I waited it out. Now my issue. Since upgrading to the latest CE version, 5 out of my 7 devices (home network) are no longer being discovered. I can confirm DNS is working. I've debugged as much as I can, including reinstalling snmpd on the Ubuntu boxes. The devices which are staying down are my Ubuntu boxes and Unifi AP and Secure gateway. Any direction on debugging would be greatly appreciated. -- Regards, Roland

TP-Link switches freeze with new Observium CE
by Attila Nagy 07 Sep '18

07 Sep '18

Hi List! Firstly our appreciations go to the team for the new CE version. Thanks a lot! Now the somewhat bitter part: we updated yesterday evening to the latest CE version and today morning we were confronted with the problem that a few Tp-Link switches have frozen. To be more precise, only the management part was frozen, so the switch was degraded to a dumb non-manageable switch. After reboot the switches return to full function only to freeze again on next SNMP poll. The switches in question are all T1600G-28TS or T1600G-28PS (poor-man's manageable gigabit switches :-)) There is no newer firmware update available for them. They worked perfectly with the previous CE version up until the update. We have other Tp-Link switches which are not affected by the same problem: TL-SG2424, TL-SG2216, TL-SG2008. We tried to narrow down the problem, and it seems that discovery works as it should, the freeze enacts during the polling, more exactly when the ports module runs. Looking at the debug log the following command produces the freeze: /usr/bin/snmpget -v2c -c 'public' -Pu -OQUs -m IF-MIB -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'switch-test':'161' ifInMulticastPkts.1 ifOutMulticastPkts.1 ifInBroadcastPkts.1 ifOutBroadcastPkts.1 ifHCInOctets.1 ifHCOutOctets.1 ifHCInUcastPkts.1 ifHCOutUcastPkts.1 ifHCInMulticastPkts.1 ifHCOutMulticastPkts.1 ifHCInBroadcastPkts.1 ifHCOutBroadcastPkts.1 ifInOctets.1 ifOutOctets.1 ifInUcastPkts.1 ifOutUcastPkts.1 ifInNUcastPkts.1 ifOutNUcastPkts.1 ifInDiscards.1 ifOutDiscards.1 ifInErrors.1 ifOutErrors.1 ifInUnknownProtos.1 ifMtu.1 ifSpeed.1 ifPhysAddress.1 ifAdminStatus.1 ifLastChange.1 ifPromiscuousMode.1 ifConnectorPresent.1 From here onward there is no SNMP response from the switch, the SYS LED stops blinking and is frozen in whichever state it was, and there is no network connectivity to the switch (does not respond to ping and the management interface is inaccessible). The dumb switch hardware was still working for some time, but this was inconsistent, some switches have frozen to a complete halt some time after, while others were still working as dumb switches. As these are under constant load we didn't had the time to more thoroughly investigate on them, we restored their functionality and disabled them in Observium. We have one extra hardware that we can put online for testing if needed. My questions would be: - Should I include a full debug log or the above info is enough? - Has anyone met the same problem/has a solution to it? - Can we know what was changed on the above command line, so maybe as a workaround we can disable that single feature? - I suspect this is a firmware issue, but I am not sure (that's why I'm asking here first, here I have way bigger chances to receive meaningful answers compared to Tp-Link's support), maybe somebody can help me narrow down the firmware bug if it is really one. Thank you guys in advance. Best regards, Tylla

Power Outage
by Ricardo Franco Cantero 06 Sep '18

06 Sep '18

Hi, What would be the best way to measure for a power outage? I see that there is a sensor for voltage. Would a Min Warn value trigger it on time to send a alert? Met vriendelijke groet, Ricardo Franco Cantero

Alert my customers
by Ricardo Franco Cantero 05 Sep '18

05 Sep '18

Hi, We monitor our clients through Observium. I wanted to know how I can add individual alert contacts so when a connection of a customer goes down, it sends an alert to us but also directly to the client who's affected. Met vriendelijke groet, Ricardo Franco Cantero

Hi, When I add an alert checker, now I need to add an Association Ruleset. It didn't used to ask for one and I can't seem to find the option to select all, like with the * How do I achieve this? Met vriendelijke groet, Ricardo Franco Cantero

How do you configure Internet traffic Today
by Thomas Steffensen 04 Sep '18

04 Sep '18

Hi, I am not sure if this is the right forum but I need some help with basic settings in Observium. I admit I have very little experience with Observium but a great deal with Solarwinds and The Dude (Mikrotik). On my main dashboard window I have a tab saying Internet Traffic Today. This monitors ports to the internet. However, we have replaced some border router and therefor I need to change which ports are being monitored and I can't seem to figure out where I change this? Can I do this in GUI?

by Samuel Werneck 04 Sep '18

04 Sep '18

Hi, I have a server running the unix agent and the postgresql module. Is it possible to create an alert checker based on the postgresql app data? Something like... if the "connection count" is below X, than generate an alert Thanks, -- Samuel Werneck
