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
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.
