I got alert mail in every 5 minutes. Bug? V2 :)

Hi All, Some week ago i wrote a mail because we found an alert bug and we got lot of mails (in every 5. minutes) instead of just 1 in 24 hours. This Observium was an updated from the 2015.07 CE to the latest (CE.0.16.1.7533). We thougth that the problem was because of the upgrade process and the alert function was new and something went bad.... Now i made a clear install of the latest Observium CE from .tgz. I added only one host, add the same alert, and i’m receiving again the alerts mail in every 5. minutes. I didn’t touch any file just the config.php because of the SQL access of the Observium! I added a host (emaussw01). It is a Cisco Nexus device with 7 FEX modules. I see the temperatures of FEXs (4 values from every FEX) all is under 50C but not one module. This module are the "FEX-111 Module-1 Die-1". This is over 50C. I add an alert, export is this: <?xml version="1.0"?> <templates> <template type="alert" description="Autogenerated observium template" version="0.91" created="Thu, 10 Mar 2016 15:29:04 +0100" observium="0.16.1.7533" id="73249fd2b23ef5f715d749ce2e98be41"> <entity_type>sensor</entity_type> <name>emaussw01 temp check</name> <message>Temp alarm!</message> <severity>crit</severity> <suppress_recovery>0</suppress_recovery> <delay>0</delay> <conditions_and>1</conditions_and> <conditions>sensor_value gt 50</conditions> <conditions_complex>sensor_value gt 50</conditions_complex> <associations> <device>hostname eq emaussw01</device> <entity>sensor_class is temperature</entity> </associations> </template> </templates> I associated one user for this check via email alert. Alert history is: Date Device Alert Check Entity Message Status 2016-03-10 15:38:26 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY 2016-03-10 15:34:15 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY 2016-03-10 15:29:12 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY 2016-03-10 15:24:06 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY 2016-03-10 15:18:29 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY 2016-03-10 15:14:07 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY 2016-03-10 15:08:29 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY 2016-03-10 15:03:51 emaussw01 emaUSSW01 temp check Fex-111 Module-1 Die-1 Alert notification sent ALERT_NOTIFY And i got email allways (1 minutes earlier) when ALERT_NOTIFY is present in the log: # grep -i "Date: Thu” /var/spool/mail/obstestuser Date: Thu, 10 Mar 2016 15:02:50 +0100 Date: Thu, 10 Mar 2016 15:07:28 +0100 Date: Thu, 10 Mar 2016 15:13:07 +0100 Date: Thu, 10 Mar 2016 15:17:28 +0100 Date: Thu, 10 Mar 2016 15:23:06 +0100 Date: Thu, 10 Mar 2016 15:28:11 +0100 Date: Thu, 10 Mar 2016 15:33:14 +0100 Date: Thu, 10 Mar 2016 15:37:26 +0100 What can i debug for resolve this problem?

Alert Checks on Observium reports device down when they are actually not
by Arya, Renuka [MED] 10 Mar '16

10 Mar '16

Hi Team, I have setup the following Alert on my Observium device. See attachment (Alert_DeviceDown). I sometimes get the alerts that the device is down . See attachment (Devices_Down). However, the devices were actually not down. So most likely it is the Server on which Observium is install, do not get a ping response from the switch(device we monitoring). I ran MTR tests between the Observium server and switch in question, I don't see any packet losses, but I do see average RTT of 0.2 ms and worst RTT as 3.8 ms. So, is it possible when Observium does not get a ping response from the switch in the desirable amount of time, it marks it DOWN. How this desirable amount is calculated. Is there way we can edit this? Or is there any other recommended way for monitoring the devices? Thanks!

db.log full after upgrade to Observium CE 0.16.1.7533
by Mike Driscoll 09 Mar '16

09 Mar '16

After upgrade, all seemed well until my disk filled up. db.log contains countless entries about unknown columns. A couple examples are below. I completed the schema update and full discovery at the end of the upgrade process per: http://www.observium.org/docs/updating/ <http://www.observium.org/docs/updating/>. Rerunning discovery.php -u says my schema is up to date. But something isn’t right. Is there a way to force the schema update to run again? Perhaps that will install all the missing columns?
