Grafana dashboard: WSO2 Proxy Service Metrics
Description: This Dashboard provides an overview of proxy services deployed in Enterprise Integrator Cluster.

This Dashboard provides an overview of proxy services deployed in Enterprise Integrator cluster. It will have dynamic panels for each proxy service deployed in Enterprise Integrator cluster and user have the ability to choose the proxy service that they want to monitor using the drop down. Following stats are displayed in the proxy dashboards.
- Up Time
- All Request Count
- Successful Request Count
- Error Count
- Error Percentage
- Deployed Node Count: Number of nodes, service is deployed
- Request Rate
- Error Rate
- Response Time : This will be show as a heat map using recorded histograms. If tracing is enabled widget will have a link to redirect users to Jaeger UI
