Grafana is an open source analytics and monitoring platform, and we use it for monitoring the health of GovWifi in realtime.
There are two self hosted Grafana instances for the Production and Staging environments, and one Grafana instance hosted by the GOV.UK PaaS team which exposes data regarding the product page and tech docs.
The self-hosted Grafana is used for monitoring GovWifi infrastructure and APIs. This Google Document contains in-depth information on the technical setup (you must be a member of the Govwifi team to view this document).
You can access the dashboard using the links below (you must be signed into the dashboard to do this):

We currently have a tab with default Google Analytics dashboard open. This will be iterated over to make it more useful in the near future.
Prometheus is an open source software application used for event monitoring and alerting. It records real-time metrics in a time series database built using a HTTP pull model, with flexible queries and real-time alerting.
We run a Prometheus server which scrapes metrics from Prometheus log exporters running on the FreeRADIUS containers.
These Prometheus exporters provide a wide range of information about the actual FreeRADIUS server state and the packages being processed.
The information is used for diagnostics and tracking service availability.
If you have SSH access, you can run the commands below to see the dashboard. If not, please speak to the reliability engineers on the team about access.
