 # tfmod-prometheus
+
+Prometheus is an open source monitoring and alerting tool designed for dynamic cloud systems and especially well suited for monitoring microservice architectures. Prometheus collects and stores metrics as time series data. Metrics are a key means in understanding an applications behavior and a critical facet of operations support. Collectively, "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." - [prometheus.io](https://prometheus.io/) 
+
+This modules uses Helm to deploy Prometheus to a cluster using the official chart. By default this will install dependent charts/components:
+- [alertmanager](https://github.com/prometheus-community/helm-charts/tree/main/charts/alertmanager)
+- [kube-state-metrics](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-state-metrics)
+- [prometheus-node-exporter](https://github.com/prometheus-community/helm-charts/tree/main/charts/prometheus-node-exporter)
+- [prometheus-pushgateway](https://github.com/walker-tom/helm-charts/tree/main/charts/prometheus-pushgateway)
+
+Versions are module variables, but latest versions are intended to be be reflected in the default values.
+
+# CHANGELOG
