The hosted grafana service has it's own page [here](/home/grafana-service).
### DN42 Infrastructure Monitoring
burble.dn42 hosts monitoring and alerting of key DN42 services, see the
[hosted grafana service](/home/grafana-service) for more details.
### burble.dn42 status

Internally, nodes are measured by [netdata](https://github.com/netdata/netdata) which provides a real time view of each node. [prometheus](https://prometheus.io/) is then used to collect and store that data for historical reporting. [grafana](https://grafana.com/) is used for visualisation, but this is not currently a public service.
