Carl Bergquist (Grafana) and Neil Gehani (Weaveworks) discuss best practices on how to get started with monitoring your application. Start capturing metrics that matter, aggregate and visualize them in a useful way that allows for identifying bottlenecks and preventing incidents before they happen.

1. Why Observability Matters?
now and in the future

2. ● Who is this for? - Software Development/DevOps teams building modern software in containers
● Why Monitoring?
● Weave Cloud Monitor - Applications/Services Monitoring (powered by Prometheus)
● Weave Cloud Ops - Infrastructure Monitoring (powered by Prometheus and Grafana)
● Grafana - Visualizing Prometheus Metrics

7. ●Deploy
○Dry run deploys - try before deploy
○Pull based Ops (GitOps)
○Fully automated or manual including rollbacks
●Explore
○Visual Map and Debug Applications -> Clusters, Pods, Containers, Services
○Time Travel - Compare states at different points in time
●Monitor
○Real-time and historical service, node, cluster monitoring
○Notebooks - Create, Modify, Save Prometheus queries (PromQL)
○Secure, Scalable, Multi-Tenant - as a Service
○Time Travel - Go back in time to see how applications behaved then and compare to now
Weave Cloud - Deploy . Explore . Monitor
