Realtime Varnish Stats with NodeJS

I’ve been performing some more tests with NodeJS and SocketIO to give much more real time updates on the dashboard and have created a test dashboard for various metrics.
Realtime Varnish metrics
The following is the metrics that I’m testing with realtime updates.
- Hit and Miss ratio
- Server stats for Memory/Disk/CPU
- Bytes sent for header and body
- Hit rate
Updated Alerts
I’ve now also added different severities to the alerts that can come in, Critical, Warning and Harmless and have the backend change of state messages coming in correctly.
