Solarwinds Observability tips&tricks

Solarwinds is known for their tool Appoptics. Sadly it has been deprecated and considered legacy.

They have released a new tool called Observability which performs the same tasks, but with improvements and changes.
Although the price has not improved, infact they hiked it up by double .

Either way, it’s still a good alternative to other APMs (application performance monitor) such as New Relic.

One thing I noticed is their documentation is lacking.

Their install instructions for Linux and PHP for example looks like this:

curl -sSO https://agent-binaries.cloud.solarwinds.com/apm/php/latest/solarwinds-apm-php.sh

sh solarwinds-apm-php.sh –service-key=yourservicekey:tag –collector=apm.collector.eu-01.cloud.solarwinds.com

systemctl restart <php.service>
systemctl restart <web_server.service>

The installed doesn’t mention it, and they have hid the so files behind non public directory service service key.
By default it installs the so-library for the current active php-cli is installed, which means you only get one PHP version library installed.

To install Observability for other PHP versions you simply change your consoles default PHP version, and it’ll pull the right version when you run the solarwinds-apm-php.sh script.

In Debian it’s update-alternatives –config php
select the version you want and re-run the script.

Dont forget to restart your PHP services (fpm) and webserver!

Cogent / Telia packetloss

There is currently pocketless towards Telia network from Västberga (5.226.32.0/21 and 46.253.192.0/20) datacenter. We’ve notified upstream transits who are looking into it.

If necessary we’ll disconnect Cogent temporarily to re-route traffic until it has been fixed, we’ll keep monitoring for now.

Update: Traffic for Västberga has been re-routed away from Cogent during the duration of the packetloss.

Outage 2024-08-12

According to our provider, tonight’s outage was extraordinary. More information about the outage can be found here: https://status.glesys.com/

In short, both A and B power went down due to an issue in the data center. We are following up with them and will send out more information once the data center operator updates us on what went wrong.

The incident started around 20:45. Adminor’s virtual services were back online after a cautious restart between 21:00 – 21:30. SAN (storage) came back immediately after the power was restored (primary + backup in Västberga). Some services may have taken longer due to fsck checks and other factors, but efforts were made to restore everything as quickly as possible.

We monitored the situation overnight, reactivated Adminor’s replications for backups, and assisted customers in restarting their physical servers where there were issues.

When: 2024-08-12 20.45 – 21.30
Where: Västberga Datacenter
Impact: Outage

Packetloss VB-B15 link

Packetloss was detected on inter-datacenter link. This was caused by a faulty fiberpatch in one of the locations.

The patch at VBDC was replaced and optics inspected.

Impact: 00.00 – 09.00 Minor packetloss on link, not causing outage notifications .
Redundancy was degraded during troubleshooting 14.00 – 15.00. No impact on service.

Resolved 15.10.

Emergency maintenance

Core switch reboot was performed 01.30 – 01.35 due to memory leak (stack bug).
A tentative fix is the reboot and to avoid causing the ACL conflict which led to the memory leak.

At 04.00 – 04.05 another test was made to replicate the issue. The issue has most likely been found and a new fix has been applied.

Longterm solution will be to replace this switch line with new core routers , Juniper MX204.
