Optimisations for huge lb_pools
by Pieter De Wit 29 Apr '21

29 Apr '21

Hi Guys, We have some pretty large lb_virtuals (12000 entries), lb_pools (180000 entries) tables. I found that the poller was struggling to keep up with this (understandable IMHO). What I did find was MySQL appeared to be the bottleneck so after some debugging I added the following indexes: create index lb_virtuals_idx_1 on lb_virtuals (device_id,virt_name); create index lb_pools_idx_1 on lb_pools (device_id,pool_name); create index lb_snatpools_idx_1 on lb_snatpools (device_id,snatpool_name); The middle one had the biggest impact, since that is the biggest table. Here is the polling result showing the difference: Time Duration 2021-04-29 17:05:02 56s 2021-04-29 17:00:02 4m 19s Hopefully this can help someone else if they have an issue like this (I hope not for your sanity :D ) or perhaps the devs can advise a better way of doing it :) P.S. - The issue was that polling kept running over each other and that cause it to spiral out of control, data gaps where getting bigger and bigger and MySQL was pinned at 250-300% CPU (4 core box this) Cheers, Pieter

New Port Alert Checks Not Working
by Andre Geißler 26 Apr '21

26 Apr '21

Hi all I configured a port alert check and set test condition to "ifOperStatus eq down" and asssociation ruleset to "Port ifAlias match *!!!*". I can see entities (276 ports) are matched correctly but are listed without the device the ports belong to. Status of alert never changes from "0 0 0 0 276" It seems associations works fine but checks aren't executed no matter which association and conditions I try. A much more complex port check I configured years ago is working fine, new ones aren't. I'm on 21.4.11258 Thanks a lot Andre

Is there a bug in the installation script? I tried to use the installation script for a fresh install on Debian 10.9. The script said I had Debian 9 and aborted. I made a fresh install av Debian and tried again. The same result. I have Debian 10.9 and the installation script says Debian 9. Is this a bug or what is the problem? ES

Add Device API - Option to provide poller id as parameter.
by Midhun Kandoth 20 Apr '21

20 Apr '21

Hi All, I am using observium apis to add devices to observium in a partitioned poller setup. But the current add device api (POST /api/v0/devices/) is not accepting poller_id as a parameter. Currently I am using MySQL Query to add devices to observium with poller_id. I could see that the API is in active development state. So it will be great if you can incorporate this request as well. Best, Midhun Kandoth

Genexis OLT/ONT Device issues
by Prasun Kumar Mitra (NOC) 20 Apr '21

20 Apr '21

Hi , We are using an OLT/ONT device Brand "Genexis" (http://www.genexis.co.in). Currently we have added Genexis- SOLT33-08P for testing. But it's *not working fully as we are not getting connected ONT information*. We have contacted the device vendor team. The *technical head of vender team is in CC " Mr. Satyam Bharati" *and they also want their devices to be compatible with observium*. *Anything needed from vendors can be made available by their team, In this regard we need support to add this device in observium so that we can monitor those devices. Please guide us what we need to do. Thanks & Regards, Prasun Mitra Alliance NOC Alliance Broadband Services Pvt. Ltd. 1st Floor, P 26/1, Dr Nani Gopal Roy Chowdhuri Ave, Entally Kolkata, West Bengal 700014 Contact No.- 1800 1200 300

Observium graphs not populated on Cisco
by Thodoris Lakiotis 16 Apr '21

*Hello there,* *We have just added a new 1002-X ASR with the following software.* *Cisco IOS Software [Amsterdam], ASR1000 Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 17.3.3* *The device is polled just fine, all Interfaces, included subifs indexed correctly and everything seems ok.* *But observium shows data on only on physical interfaces, but not to Subinterfaces.* *To be more specific, it graphs only physical interfaces, but not routed VLAN interfaces.* *Have you ever seen anything like this?* Thodoris

linux persitance SNMP indexes
by Edvinas Kairys 15 Apr '21

15 Apr '21

Hello, As i know there're no plans to workaround not persistent SNMP indexes 'feature' in Observium. But maybe there any linux snmp persistence workaround suitable for Observium, and its plugins (for example, weathermap) to leave the linux snmp if indexes unchanged after server reboot, etc ? Thank you

Changing some devices to only poll every 10 or 15 minutes temporariliy?
by Damien Gardner 12 Apr '21

12 Apr '21

Hi all, I have a bit of an oddball one, hoping it's not horrible to be able to do... We have a few devices which have recently started taking > 5 mins to complete polling. This is leaving large gaps in our logs, and is also effecting discovery (as the polling of the devices are piling up on top of themselves and pushing load on those devices up heavily). For now I've just turned off polling on those devices, but that's not ideal either.. Is there a way to be able to just poll those manually at say 10 or 15 minute intervals? I shoved them into a group and excluded that group from our polls - and then ran poller.php -h deviceid on one device in cron every 15 mins to see how it would go - but we just get no graphs.. Also as a test, tried using rrdtool tune --step 900 to change the step size to 15 mins, but also no go (didn't really entirely expect it to..) Is there a not-horrible (or if it has to be, I'm ok with horrible in the short-term until the vendor can figure out what on earth is going on..) way to get these being polled on a 15-minute interval and also going into rrd's? (We're on the current paid subscription version, if that helps) Thanks, Damien [https://info.serversaustralia.com.au/hubfs/Brand-2018/logo-font-sau.gif] Damien Gardner Jnr Senior Dev Ops P: (02) 8115 8812 4 Amy Close, Wyong, NSW 2259 Need assistance?

Unable to delete alert checkers
by Luis Londoño 26 Mar '21

26 Mar '21

Cant delete an alert checker. When I click on Delete the confirmation prompt comes up and the checkbox is already selected but the delete alert is disabled. Unchecking the box enabled the button but clicking it doesn't delete the alert. We are on 21.3.11160 (24th March 2021) [cid:image001.png@01D7216C.5095D420] Did find in the HTML to enable the button when the checkbox is pressed was to remove the "disabled=1" [cid:image002.png@01D7216C.8C292410]
