Viewing Monitoring Metrics

Cloud Eye monitors the running status of your graphs. You can view the monitoring metrics of GES on the Cloud Eye management console.

It takes a period of time for transmitting and displaying monitoring data. The GES status displayed in the Cloud Eye monitoring data is the status obtained 5 to 10 minutes before. You can view the monitored data of a graph 5 to 10 minutes after it is created.

Prerequisites

The created graph is running properly.
The graph has been properly running for at least 10 minutes. For a newly created graph, you need to wait for a while before viewing its monitoring metrics.
You can view monitoring data of graphs in the running, importing, exporting, and clearing states. The monitoring metrics can be viewed after the real-time service starts or recovers.

Viewing Metrics

Log in to the GES management console.
In the navigation pane, choose Graph Management. In the Operation column, choose More > View Metrics. The Cloud Eye management console is displayed.
On the monitoring page for GES, you can view the figures of all monitoring metrics.

The system allows you to select a fixed time range or use automatic refresh.
1. Fixed time ranges include 1h, 3h, 12h.
2. The automatic refresh interval is 60s, which is the user monitoring period.

Metrics

This chapter describes metrics reported by GES to Cloud Eye as well as their namespaces, lists, and dimensions. You can use the management console and APIs provided by Cloud Eye to query the metric and alarm information generated for GES.

The namespace of the metrics reported by GES to Cloud Eye is SYS.GES.
