every once in a while I get songs from All Hail West Texas stuck in my head and it's absolutely impossible to turn it off. help

Result: Clean latency metrics that automatically filter out low-traffic noise. Your dashboards stay focused on clusters that matter.

The earlier graph is now trimmed, showing just the series that matter.

Shoutout to Datadog's query engine team for enabling this kind of creative solution! 🙌

5/5

The actual query looks like this:

cockroachdb.sql.conn.latency * (cutoff_min(cockroachdb.sql.new_conns, 5) / cutoff_min(cockroachdb.sql.new_conns, 5))

When new_conns < 5, the series becomes null and nullifies the latency graph.

4/n

The solution:
1. Use cutoff_min() on your modulating metric (the connection rate, in the example)
2. Multiply your target metric by modulating_metric/modulating_metric

This creates a 1 (keep) or null (filter) multiplier! 🪄

3/n

An example problem: Monitoring SQL connection latency across a fleet of CockroachDB clusters gets noisy when some clusters have quiet workloads. Low-traffic clusters skew dashboards 📊

How do we monitor SQL connection latency, but ONLY when connection rates are high enough to be meaningful?

Ever faced with a highly grouped graph that looks chaotic like this in Datadog?

Here's a useful trick: how to filter metrics based on OTHER metrics, to tame graphs like this one.

Datadog doesn't make this especially easy... but we can do it with some elbow grease! Here's how.

Probably, but you'd just have to do everything yourself which may or may not appeal or ultimately be cost effective to maintain.

The ish is that the cheap log tier (flex) doesn't support arbitrary metric creation. The more expensive one (standard, what they used to have exclusively) supports this in full. In practice you can use a mixture of the two tiers, but I do hope they improve this behavior

I'm not sure what you mean by visualizing them over time as a trace, but I think so? For example, you could write a filter on a "trace id" attribute and show log events with a given trace id.

No need to select dimensions, no.

Deriving SLOs and metrics - yes, ish...

Datadog's flex logs system provides a reasonable method in my experience - filter / group by / aggregations across logs with arbitrary attributes, plus graphing on top of that output. Or did you mean something more specific?

this is how I want my sunglasses to look

Scene Me Up Harry on the good part about scenes

once a scene starts, it's hard to de-scene it! I'm clearly part of the problem.

currently most Bluesky posts are about Bluesky. does that mean Bluesky is a scene?

yes why is that

am i doing this right

your what

thoughts on Arc browser? I've been using it for about a week. some good some bad. I like the mini browser. I like the Spaces. I don't like that there aren't PWA "apps" on Mac.

good morning bluesky!

I love that set too

The vibe on Twitter vs. BlueSky

this app is also so nicely snappy to use! it's quite a different kind of thing than Mastodon which let's be honest felt a little bit like Year of the Linux Desktop.

I hope it takes off.

buddyyyyyy

hey homie!
