MySQL IO Wait
by Lars Joergensen 02 Aug '22

02 Aug '22

Hey list We keep adding devices to Observium, and it seems we're getting close to some tipping point for MySQL performance. Looking at output from "top" we frequently see high iowait: [cid:image001.png@01D89790.EF319B00] Looking at iotop, it seems that MySQL is the aggressor here: [cid:image002.png@01D89790.EF319B00] We figured syslog was the culprit at first, and tried disabling that for a while to see if stuff died down. It did not. Been playing a little with mytop, and even though we have a QPS around 780, it's not possible for me to nail down what queries are hogging the IO on the server. I googled around and did some changes to the InnoDB, and though I saw improvements, they were not as massive as I had hoped. This is what I currently have changed from defaults: [mysqld] # This is a little too much for the installed 8G in the machine and will be adjusted at a later time. Just trying stuff out now. innodb_buffer_pool_size=6G # We have fast SSD drives on vSAN innodb_io_capacity=1000 # Don't flush file write so often, be more relaxed. innodb-flush-method=O_DIRECT_NO_FSYNC So I'm kind of stumped here. It's not killing Observium totally just yet, but we have experienced some outages this week and will probably see more as we keep adding devices. Any recommendations will be much appreciated.

Alert checker failing
by Lars Joergensen 02 Aug '22

02 Aug '22

Hi list Why does this fail: [cid:image001.png@01D8A68F.E52D3930] I tried with both "online" and "onLine", but saw no difference. I tried deleting and recreating the check to make sure nothing was stuck somewhere. It went straight to failed on the first poll. I'm trying to monitor a bunch of UPS devices. They are from diffent vendors, and some reports "normal", other reports "onLine". The ones reporting "normal" works fine, but the ones reporting "onLine" all fails.

Mailing list migration
by Adam Armstrong 01 Aug '22

01 Aug '22

Hi Guys, We've migrated the list to a new setup running Mailman 3. It all seems to work ok, and I've important the historical archives which are now available at https://lists.observium.org/hyperkitty/list/observium@lists.observium.org/ It will likely be necessary to use the password recovery process for the Mailman account in order to access the archives and control the settings of your subscription. It might have migrated existing passwords from the old system, but who knows, Mailman 2 was ancient! This doubles as a test post! :D Thanks, adam.

Observium Community Edition 20.9.10731
by Stuart Dyer 28 Jul '22

28 Jul '22

Hi Everyone, Need some advice. I'm running Observium Observium Community Edition 20.9.10731 on Debian 8.4 and I want to move this to a new server. I tried to update to the latest community edition but when I ran discovery it could not find any modules so I backed out of the upgrade. Can I build a new server, install the latest community then move the database over or do I need to install same versions of Observium on both servers ?

IPv6 total graphs
by Matteo Sgalaberni 18 Jul '22

18 Jul '22

Hello, I'm using the Port description Parsing to aggregate graphs in the section "Transit" and "Core". It's very useful so I can know the total traffic that is forwarded on my network. On all devices I have also the IPv6 graphs inside the device interface. Question1) I would like to see the total traffic differentiated by ipv4/ipv6 on the same way of tab "Transit/Core". I want to know the total traffic IPv6 that is forwarded globally or by transits. Question 2) The graph "Device total traffic in bits/sec." report the total traffic I immagine. Is is possible to have that total traffic of the device differentiated by ipv4/ipv6? Thanks Matteo

Help Request
by Matthew Haney 18 Jul '22

18 Jul '22

I'm not sure if this is the correct manner, but I'm looking for some kind of support. We are using Observium with ops genie, and around March of this year our Alerts are way less than normal. We'd get 10-25 a day, no almost nothing. I have 0 background in any database knowledge, and can really only fumble my way through Linux commands.

Windows Services
by Stuart Dyer 11 Jul '22

11 Jul '22

Hi Everyone, I'm on an old build of the community edition, 20.9.10731 (22nd September 2020). Noted in the demo on the website Observium can monitor windows services on windows servers. If I upgrade to the latest community edition does that come with the ability to monitor windows services or do I need to go to the paid edition ? if so can I use an alert checker to send an email if a specific windows service changes its status from running to anything other than running ?
