If you're already paying for Datadog the price probably isn't an issue for you though.
Have you considered integration with other CI/CD pipeline engines or it doesn't matter as long as you git-commit?
Thanks in advance.
With regards to cost, you can self-host GitHub Actions runners. Internally we use an autoscaling group of spot instances via k8s, which is much cheaper than GitHub-hosted runners. We actually didn't do it for the cost, we did it because we wanted a local cache to persist on machines during the day, for performance reasons. When cost is a factor, having an analytics system help you optimize your jobs is super important.
I really like this - with this product, we're focusing on trying to tell the story and also make the data actionable. I'm hoping we can both show that there is a problem, as well as guide you to how to fix it. Otherwise, at the end of the day it's just colorful lines.
We've got a few companies using it, and had other users in our community tell us "It's a very helpful tool that I didn't even know I needed". Even we ourselves have made a number of surprising discoveries about how often some of our hourly/nightly workflows have been failing by dogfooding this.
Let us know what you think! :)
