Some links on hetrixtools.com Uptime and Blacklist monitoring, and PagerDuty integration.

Historically I have been using Uptime Robot a lot, but in practice they are only good for HTTP/HTTPS uptime checking and TCP connection checking. SMTP checking requires more than just a valid TCP check which they can’t, so I took a look at hetrixtools.com.

They advertise being forever free when using a limit number of Uptime/Blacklist endpoints as per

[Wayback/Archive] Free Uptime Monitor & Blacklist Monitor- HetrixTools

  • 15 Uptime Monitors • 1 Minute Interval
  • 32 Blacklist Monitors • Checked Everyday

FREE Forever!

Unlike many other free uptime checking tools, their interval is better.

A thing to consider is that, like many online-first companies, they do not provide company details on either of these pages which you have to agree with when signing on for their service:

GitLab pages issues today again? (and report on 2023-10-30: Gitlab.com is down (#17054) · Issues · GitLab.com / GitLab Infrastructure Team / production · GitLab)

Posted by jpluimers on 2024/03/12

Still working on handling open Chrome tabs after having moved in the period that GitLab had quite a few issues causing my PagerDuty alerts to go wild.

Today PagerDuty gave me 7 calls in 4 hours again (see [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “@gitlab Since 20240312T1727Z I get PagerDuty alerts from HetrixTools for some pages hosted on GitLab. It would be nice if someone could have a look at gitlab.com/gitlab-com/gl-infra/production/-/issues/17717“).

In adddition I need to check if anything made it to the GitLab issue list from the 20230827 connectivity issues I mentioned at [Wayback/Archive] Jeroen Wiert Pluimers @wiert@mastodon.social on X: “Is it @gitlab hosting having transcontinental issues, or are other continental connections affected as well? These are from two different *.gitlab.io pages as measured via @HetrixTools . No issues are listed at status.gitlab.com“.

Back then, this was the most important one: [Wayback/Archive] GitLab System Status: GitLab.com availability issues – October 30, 2023 15:39 UTC

Likely because of this, wiert.me.gitlab.io had been down for a while as well on 20231031 (see [Wayback/Archive] wiert.me.gitlab.io (Recent History) – HetrixTools down from 2023-10-30T15:24Z until 2023-10-30T16:14Z for 3 + 3 + 11 + 27 = 44 minutes.)

Back then, the hardest part was to quickly find out if there was indeed an issue being investigated at all.

The GitLab status multi-media account on Twitter just points to the status page, which makes it hard to find the underlying issue.

I didn’t archive that one in time, but when I got the alerts it didn’t show anything and when it was resolved it was already beyond the cut-off timestamp to mark it as “same day” and the graph didn’t show much down-time [Wayback/Archive] GitLab System Status graph didn’t show much down-time:
