●●SolidSolve My ProblemShip It

Automates post-deployment log diffing across Kubernetes and Datadog dashboards.

Strengths
  • Eliminates manual cross-dashboard queries by automatically clustering new/missing log patterns
  • Reads log lake and compares pre/post deployment state without extra setup
  • Bird's-eye regression detection reduces time to spot deployment issues
Weaknesses
  • Requires Kubernetes + Datadog (excludes teams on other stacks like CloudWatch, ELK)
  • No evidence of open-source adoption or community traction yet
Target Audience

SREs, DevOps engineers, platform teams managing Kubernetes deployments

Post Description

I built this tool that connects to your Kubernetes and Datadog via read access. Collects logs before(60 minutes) and after(15 minutes). And compares them to catch regressions early on. This eliminates the need to jump across 5-6 dashboards to know if the deployment is working as expected, just by looking at the telemetry data. It's a thin intelligence layer for deployments. Usually, you get this by looking at your log data lake, making a query and running a comparison manually. This automatically looks for new log clusters, missing log clusters formed and error spikes. Looking at this alone can give you a bird 's-eye view of how the deployment went.
