by Tibi, Saleh 13 Nov '20

13 Nov '20

Hi guys, our instance: observium 20.10.10799(rolling) i have two issues (a question and a problem ) in the subject Alert Checkers. The question: Is it Possible to configure my alert Checkers that test two different sensors (different entities ) I have two sensor - flowrate Sensor - Valve Sensor For example like this: Require all conditions: (flowrate Sensor)sensor_value eq 0 (Valve Sensor)sensor_value eq 0 What I saw in the documentation that we can check only one entity at a time. The Problem: Steps: 1- Creating new alert Checker 2- filtering devices or sensors in Entity Association Ruleset (for example: Sensor Group in WaterSensor) 3- save changes (all sensor will be listed ) 4- rebuild 5- all sensor appearing in status unknown 6- wait a 3 or 4 minutes all sensors will disappear any advices or hint ? thx in advanced an have a nice Day Saleh Tibi Mit freundlichen Grüßen Saleh Tibi ---------------------------------------------- Ing: Saleh Tibi (Herr) IT-Spezialist für Maschinensäle und Überwachung Zentrum für Informations- und Medientechnologie (ZIM)|Raum 25.41.02.27 Heinrich-Heine-Universitaet Duesseldorf Universitaetsstrasse 1 40225 Duesseldorf Email: Tibi.saleh(a)uni-duesseldorf.de<mailto:Tibi.saleh@uni-duesseldorf.de> Phone: +49-(0)211-81-14051

Syslog view sort order by date
by Stempien, Dave 12 Nov '20

12 Nov '20

Hello, Is it possible to sort the syslog messages in both the syslog view and in the dashboard widget by date? The event log shows newest entries on top but syslog shows oldest (which is 30 days – the number of days in our case that we retain syslog data). Thanks, -- David Stempien, University of Rochester University IT - Core Technology Services Tel: 585.276.6957 Email: david.stempien(a)rochester.edu<mailto:david.stempien@rochester.edu>

Polling partitioning / distributed polling
by Brad Bendy 12 Nov '20

12 Nov '20

Hi, I've set this up per what I can find in the docs. Master server has RRDcached running, MySQL and web server. I have another server acting as poller server. I go to that server and add hosts, the host add find. All the graphs are failing and on the local server i t shows nothing in the RRD dir (which is right I would think), on the remote hosts it shows RRD files but when I do a debug I see "file already exists" and it does on the remote server. Looking at the rrd.journal file I see updates being issued and see no errors. On the polling server I have added: $config['rrdcached'] = "x.x.x.x:42217"; $config['rrd']['no_local'] = TRUE; And updated cron to: */5 * * * * observium /opt/observium/observium-wrapper -i 1 -n 0 discovery --host new >> /dev/null 2>&1 # Run multithreaded poller wrapper every 5 minutes */5 * * * * observium /opt/observium/observium-wrapper -i 1 -n 0 poller >> /dev/null 2>&1 As I have one poller server and this is the first one. I see no other errors in other logs but all graphs show "error drawing graph". Is there something else in my config I am missing to make this work? Thanks

Graph Data Missing after Upgrade RAM
by Aulia Rahman 11 Nov '20

11 Nov '20

Dear All, I'm using Observium 20.1.10233 (stable) Enterprise version. Observium sometime error on database when access from web Image1.jpeg At that time the graph stop add new data. there's a notification in console like picture below, so I need to restart the database service. image2.png Access server and try to see HTOP image3.png Then check the log image4.png After restart database service, the graph starts to add new data again. Then, I upgraded the server RAM from 12 GB to 24 GB on 9 November 2020 at night. This server uses ramdisk configuration on SSD. After the server booted up the graph didn't add new data until today 11 November 2020 at 00:00 the graph started to add new data again. But, all previous data graphs on all devices before 11 November 2020 are missing. Here's the screenshot for the missing data for example on one device after upgrade. image5.png Here's the HTOP from the observium server after upgrade image6.png I've restore to date 8 and 7 November but the all graph show "Draw Graph Error" image7.jpeg & image8.jpeg When check the rrd folder from the server restore, It just only show a few device folder. I assume that folder still hold on ramdisk, but if I see log for ramdisk it sync every 2-5 minutes to hardisk. Please tell me step-by-step how to troubleshoot & recover it. All image you can see on this link: https://drive.google.com/drive/folders/1u8sx3_a_qJN9Kpr_gmgEND3MsV4Vd0Vj?us… Demikian yang dapat kami sampaikan, terimakasih. Regards, Aulia Rahman

Rancid git with remote pollers
by Brad Bendy 09 Nov '20

09 Nov '20

Hi, I know this is slightly off topic but was wondering if anyone has ran into this. We have rancid on our remote pollers working and grabbing configs. Now on a single Observium instance you just enable it in the config and the integration works spot on as the SVN/GIT is local. Has anyone got this to work where they store the configs locally on the remote poller and then push a copy to the master observium box so they show up in the GUI? Or are you using a central GIT server on the master and just the proper settings in the rancid.conf file? Thanks

Observium Entreprise Edition and multiple pollers?
by Johann Mallet 06 Nov '20

06 Nov '20

Hello, Do you have any guide about Entreprise Edition? How do multiple pollers working on different servers work? Do we need to use RRDCached and/or NFS shares? Or poller instances store on local servers and Observium interface make proxy for RRD data? Best Regards, Johann

Widget Configuration
by Ahmed Rahal 05 Nov '20

05 Nov '20

Hi ! I saw that the widgets on dashboards can have specific configurations (database table 'dash_widgets', field 'widget_config') but I seem to find no documentation about this. Also the UI somehow does not allow me to change any of the parameters. Am I missing something here ? Ahmed.
