Delay on down devices
by Louis Bailleul 14 Mar '16

14 Mar '16

Hi, Is it possible to add a delay for the built in down device alert ? Or even better, can I replace the built in alert with custom checkers ? So I can add a delay on specifics sets of devices.

backup script for db, config.php, rrd/
by Nick Schmalenberger 14 Mar '16

14 Mar '16

Hi all, I spent my Sunday afternoon (on-call, luckily quiet though :) writing this backup script for Observium. It takes a backup destination directory and number of backups to keep using rotation which is 0 by default. Then it makes a tmp directory. It copies config.php there, does a mysql dump, and copies rrd/ into the tmp directory. It tars up the tmp directory into a tarball in the backup directory and deletes the tmp directory. It is meant to run from the scripts/ directory, it maybe isnt as polished as the other main scripts or compatible with all systems because of different options with the commands it runs. Its working for me though on my Ubuntu 14.04 test system. Please offer suggestions! Thanks. -Nick

Changing the Mysql connections graph format
by Louis Bailleul 11 Mar '16

11 Mar '16

Hi, I found the Mysql connections graph a little difficult to read. So I changed it to use lines instead of stacked area. It is still not perfect because of the huge scale imposed by drawing the maximum number of connection and maximum number of connection reached. But at least you can actually read the value of your spikes of connections instead of working out the difference between the number of connection + max number of connection reached.

Howto Integrate observium alerts with external event monitoring tool
by Ruiz, Carlos 11 Mar '16

11 Mar '16

good morning everyone, We're evaluating to use observium as our hardware monitoring solution for some datacenters, but we need to clearly understand how can we integrate the generated alerts in the tool with external event monitoring solutions that are the ones used by our Operation Center guys. I guess that we can run queries against the mysql table hosting such events, is there any other possibilities? Maybe interact with mysql DB is the recommended way, that way can any of you share with me the data model of such table? Thanks in advance for your help and sorry for the generic questions, but we're starting with the evaluation activity and we're at observium rookie level Kind Regards -- Carlos Ruiz Compute System Management Senior Engineer Roche Farma, S.A.Josefa Valcarcel, 40.

Avoid adding round robin dns devices
by Louis Bailleul 11 Mar '16

11 Mar '16

Hi, I have some devices that are configured with a round robin DNS entry. I believe that as we are running lldp on servers too, the auto discovery pick them up and add them. But as the picture below shows, this is pretty much useless as each polling end up on a different server. (You can see that the sysdescr and sysname contains contradictory data : lxfer01 and lxfer02) Would it be possible to detect that the FQDN is a round robin alias and avoid adding it as a new device ? And it would be perfect if it could be the same for CNAME as well, as it is not really worthwhile having Observium polling a node for each of its aliases.

I got alert mail in every 5 minutes. Bug? V2 :)
by Laszlo Nemeth 11 Mar '16

11 Mar '16

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!
