+# Getting started with genestack monitoring
+
+In order to begin monitoring your genestack deployment we first need to deploy the core prometheus components
+
+## Install the Prometheus stack
+
+Install [Prometheus](prometheus.md) which is part of the kube-prometheus-stack and includes:
+
+* Prometheus and the Prometheus operator to manage the Prometheus cluster deployment
+* AlertManager which allows for alerting configurations to be set in order to notify various services like email or PagerDuty for specified alerting thresholds
+
+The [Prometheus](prometheus.md) kube-prometheus-stack will also deploy a couple core metric exporters as part of the stack, those include:
+
+* Node Exporter(Hardware metrics)
+* Kube State Exporter(Kubernetes cluster metrics)
+
+## Install Grafana
+
+We can then deploy our visualization dashboard Grafana
+
+* [Install Grafana](grafana.md)
+
+Grafana is used to visualize various metrics provided by the monitoring system as well as alerts and logs, take a look at the [Grafana](https://grafana.com/) documentation for more information
+
+## Install the metric exporters
+
+Now let's deploy our exporters!
+
+* [Mysql Exporter](prometheus-mysql-exporter.md)
+* [RabbitMQ Exporter](prometheus-rabbitmq-exporter.md)
+* [Postgres Exporter](prometheus-postgres-exporter.md)
+* [Memcached Exporter](prometheus-memcached-exporter.md)
+* [Openstack Exporter](prometheus-openstack-metrics-exporter.md)
+
+## Next steps
+
+### Configure alert manager
+
+Configure the alert manager to send the specified alerts to slack as an example, see: [Slack Alerts](alertmanager-slack.md)
+
+... and more ...
+
+### Update alerting rules
+
+Within the genestack repo we can update our alerting rules via the alerting_rules.yaml to fit our needs
+
+View alerting_rules.yaml in:
+
+``` shell
+less /opt/genestack/kustomize/prometheus/alerting_rules.yaml
+```
