Prometheus
Info:
This template deploys a collection of containers based upon the technologies below, once deployed you should have a monitoring platform capable of querying all aspects of your environment with some nice pre-built dashboards. In this deployment the following technologies are utilised to make this as useful as possible.
- Prometheus - Used to scrape and store metrics from our data sources. (https://github.com/prometheus/prometheus)
- Prometheus Node Exporter - Gets host level metrics and exposes them to Prometheus. (https://github.com/prometheus/node_exporter)
- Ranch-Eye - Pre-configured lightwieght haproxy to expose the cadvsior stats used by Rancher's agent container, to Prometheus. (https://github.com/Rucknar/ranch-eye)
- Grafana - Used to visualise the data from Prometheus and InfluxDB. (https://github.com/grafana/grafana/)
- InfluxDB - Used as database for storing rancher server metrics that rancher exports via the graphite connector. (https://github.com/influxdata/influxdb)
- rancher-api-integration - Allows Prometheus to access the Rancher API and return the status of any stack or service in the rancher environment associated with the API key used.(https://github.com/Limilo/prometheus-rancher-exporter/)
To get the full compliment of metrics available,you need to configure the Rancher graphite.host address. This can be done automatically when you deploy the template by choosing the option below, for more information or how to do this change manually,see the following guide
All components in this stack are open source tools available in the community. All this template does is to bound them together in an easy to use package. I expect most people who find this useful will make use of this as a starting point and develop it further around their own needs.
Deployment:
- Select Prometheus from the community catalog.
- Click deploy.
Usage
- Grafana will now be available on, running on port 3000. I've added a number of dashboards to help get you started. Authentication is with the default
admin/admin. - Prometheus will now be available, running on port 9090. Have a play around with some of the data. For more information on Prometheus - https://prometheus.io/docs/introduction/overview/
