Day 73(DevOps)Monitoring - Grafana✔️ 🔥

🚀🚀Hope you are now clear with the basics of grafana, like why we use, where we use, what can we do with this and so on.🚀🚀

Grafana is for observability.

Loki(log capturing) is a log aggregation tool.

Prometheus is a metrics monitoring tool(time series data/metrics)

Now, let's do some practical stuff.
