+# Overview
+
+## Prometheus
+
+Prometheus, a [Cloud Native Computing Foundation](https://cncf.io/) project, is a systems and service monitoring system. It collects metrics
+from configured targets at given intervals, evaluates rule expressions,
+displays the results, and can trigger alerts if some condition is observed
+to be true.
+
+### Highlights
+
+- Consumes up to 800,000 metrics per second on a single server
+- Static Go Binary
+- Support both pull and push methods
+- Large number of clients (cAdvisor, node-exporter, experimental docker support in 1.13)
+- Supports advanced rule evaluation such as linear predictions and quantile analysis
+
+### Caveats
+
+- No down-sampling support
+- No official long-term storage support (two week default)
+- No clustering (must run multiple instances for redundancy)
+- Must run separate alert manager (or depend on Grafana)
+
+### Pull versus Push
+
+- Both are scalable
+- Adopt the model that makes sense in your environment
+- Personally prefer pull, no reconfiguring of clients to deploy a new instance
+
+## Grafana
+
+Creates beautiful charts from time series databases, including Prometheus and other.
+
+### Highlights
+
+- Prefered Prometheus visualization tool
+- Built-in alerting as of 4.0
+- Query syntax is identical to Prometheus
+- Canned dashboards for cAdvisor, node-exporter, Redis etc available on their website
+
+## cAdvisor
+
+- Container exporter from Google
+- Native Prometheus support at /metrics
+- Provides network, storage, CPU and memory metrics per container for Prometheus
+- Canned dashboard available for Grafana
+
+## Custom Endpoints
+
+- Build /metrics endpoints directly into your application
+- Expose metrics on latency, number of calls and other metrics directly to Prometheus
+
