Re: [Observium] Graph Data Missing after Upgrade RAM

Dear Adam, Sorry to resend because I didn't get the answer, thanks before. > It’s likely that you need more CPU, rather than more RAM. Ending up in these out of memory scenarios are usually because the CPU was too slow and too many processes piled up. The processor full if there's a poll is running after that it will normal again. I've follow the tutorial to using persistent ramdisk https://docs.observium.org/persistent_ramdisk/ If ramdisk, RAM and swap are full, does the RRD still written ? Because in that condition, the graph not written and there's an error when access the gui: *"DB Error 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)*" after restart the DB service it will normal again. please advice. >If you can’t see historic data, it means the RRD containing the historical data has been somehow overwritten. Observium won’t do this by itself, so somehow you managed to delete or move the original RRDs. >You can restore the RRDs from backup, and it should write to these. I can manual restore from backup of the backup ramdisk, thanks. Because when I try to manual extract the ramdisk data from LZOP first backup file it end with error. > Though, if the RRDs have somehow disappeared, I’d check to make sure you don’t have some form of filesystem/storage corruption, because the two might be linked. After investigate, when the shutdown process, the ramdisk didn't write the latest data before the server turn off. Because I didn't see any log about Ramdisk write data to hardisk. How to achieve it ? because in the document didn't explain detail about it. When startup process it succesfull load the data from ramdsk via rc.local script but the data loaded is corrupt, I can confrm this because when I try to manual extract from LZOP compression end with error, only some graph can be restored. Please advice. > BTW, please don’t send images to the mailing list. Sorry I've resend the mail but forgot to cancel the first one. Demikian yang dapat kami sampaikan, terimakasih.

New OS support
by Craig Smith 18 Nov '20

18 Nov '20

Hello, I'm looking for someone that can add support for a couple of Telco Systems (www.telco.com) models (T-Marc 3308 & T-Marc 3348S) to Observium. I can provide MIBs and access remotely to the devices for development. My company is willing to pay a resonable price for a set of agreed features being supported, and for the work to be contributed to Observium.

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

Hi, There is an in-progress case with support for PacketLight DWDM boxes. It seems to be from December 2019 and with Mike Stupalov as assignee. https://jira.observium.org/browse/OBS-3176?jql=text%20~%20%22packetlight%22 Any news regarding when this will be working ? We have some new PacletLight boxes we would like to monitor, and there dosen't seem to be any sensors available.

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
