Cloudprober

An active monitoring software to detect failures before your customers do. Blog at: Github:

How to decide what to probe:

Rank your critical user journeys. List which systems and interactions each one covers. Skip any that aren't adding new coverage.

Maximum structural validation, minimal redundancy.

Getting an org to invest in probers is hard. Deciding what to probe is harder.

Most solve it by probing everything — expensive fast, and it ends with a fleet nobody trusts.

Probe systemic issues and critical user journeys. Not every feature.

1/ Self-reviewing LLM-generated code matters. Here's a real example from a Cloudprober PR where Claude Code's solution worked but had some reliability problems:

So glad to see @cloudprober being used in more and more places. This is from @rubykaigi (a popular Ruby conference in Japan).

See https://t.co/yPZJCQAruC for the known list of large organization using Cloudprober.

. @cloudprober v0.14.1 matures browser probe functionality further with better UI, filtering, retries, and cleanup; rolls out a convenient single-run mode with JSON output; and includes improvements across networking, Prometheus integration, documentation, and build reliability.

Cloudflare’s Scaling with Safety blog (link in reply) highlights @cloudprober as key to verifying performance during their migration! 🛠️ Built with grit at Google Cloud, it’s rewarding to see its trust in action. #Cloudprober #SRE #monitoring

Finally got around to adding a configuration guide for @cloudprober

Published new documentation on OAuth support in @cloudprober:

news: Added TLS support to TCP probe: https://t.co/OrAi3iM41l… Add TLS check to TCP probe by just adding `tls_handshake` to `tcp_probe`.

Yay!!

Fixed a really old bug in Cloudprober's UDP probe today:
https://t.co/aaE2FyQyr3

Our UDP probe is special - it allows timeout to be bigger than interval, and uses multiple src ports to increase the network coverage. As a result its implementation is relatively more complex.

[Manu Garg @manugarg]

Since it happened much after the release, it's not very well known that Cloudprober supports alerting directly. Some organizations are already making use of this feature. I wanted to make sure more people are aware of it 🙂

Working on adding "browser" probe type to @Cloudprober: https://t.co/34tgxuyTWE. It's coming along pretty nicely. This was one of the longest known gaps in #cloudprober, compared to large synthetic #monitoring providers like DataDog.

We're using #playwright to run the actual tests.

Just cut a new release of Cloudprober: https://t.co/97r19CRfjb

Many improvements and a couple of bug fixes.

[Manu Garg @manugarg]

Why do we need probers? I've answered this question so many times in the last 2-2.5 years, I decided to write a blog post about it.

And it's done. Cloudprober's logger uses log/slog now. Logs are now in logfmt format (key-value pair) by default, and can be switched to JSON format with the "--logfmt=json" flag: https://t.co/2OiGaTugAd

Cloudprober website has a new look: https://t.co/tHtcWjA8Kb. I've also updated the #Kubernetes documentation[1] to introduce the the newly added k8s_targets, and simplified the targets documentation in general.

New release of Cloudprober (https://t.co/raB0E06GE4). Minor bug fixes and improvements. In case you missed the last release announcement, Cloudprober now has a shiny probes status UI at <prober-host>:9313/probestatus (https://t.co/1xet1WSK9M)

MacOS's recvmsg() behavior tripped Cloudprober up. It works differently for IPv4 and IPv6, but the mitigation that we used for that, applying a darwin-specific socket option - IP_STRIPHDR, stopped working for some reason (or maybe it never worked). https://t.co/bfXYaIX5Lu.
