Who was involved in setting up monitoring and what tools were used?

I was responsible for monitoring setup in projects as part of the DevOps and backend team. I used the following tools:

• Prometheus — for collecting metrics from applications and infrastructure.
• Grafana — for visualizing metrics and creating dashboards.
• Alertmanager — for configuring alerts on critical events.
• Sentry — for monitoring errors and exceptions in Python applications.

The setup process included:

• Instrumenting code to export metrics (for example, using the prometheus_client library for Python).
• Configuring exporters for system metrics (CPU, memory, disk).
• Creating dashboards in Grafana for key indicators (latency, errors, load).
• Setting up alert rules based on thresholds to respond promptly to issues.

This approach allowed for quick detection and resolution of failures, as well as analyzing application performance.
