How We Work

Our preference is to work asynchronously, within our project issue tracker as described in the project management section.

The team also has a set of regular synchronous calls:

1. Environment Automation Team Sync (alternate weeks):
   1. EMEA/AMER: Tue 15:00 UTC (Good for EMEA and US East)
   2. PST/APAC: Wed 00:00 UTC (Good for APAC and US West)
2. Dedicated on GCP - Weekly Demo: Wed 07:30 UTC
3. Dedicated Group Demo

Reviewer roulette

Reviewer roulette is an internal tool for use on GitLab.com projects that randomly picks a maintainer + reviewer. Environment Automation uses it to spread the MR review workload. To do so:

1. Go to the reviewer roulette page.
2. Click on Spin the wheel.

See the full MR process.

Example responses

Here are some concrete examples of responses to capacity planning alerts.

• Removing a metric from capacity planning - Advanced search memory pressure does not follow long-term trends and was not a useful prediction. It remains a metric that is alerted on if it exceeds practical limits.
• Remove saturation metric entirely - kube_pool_cpu was incorrect in many cases, and difficult to get right. It needed to be replaced with a different saturation metric (node-based CPU).
• Add Saturation metrics - Kubernetes PVCs were not being monitored at all, leading to near-miss incidents
• Fix the saturation metric - Advanced search disk was inaccurate and needed to be replaced with better promql expressions
