Metric Explorer

Prerequisites

A Hologres real-time data warehouse must be connected.

Procedure

1. Log on to the CloudMonitor 2.0 console, select the target workspace, and in the navigation pane on the left, choose All Features > Hologres Insight.

2. In the top navigation bar, select Metric Explorer to query and analyze metrics across different instance types and dimensions.

3. Query CloudMonitor metrics for connected Hologres instances. Agentless metrics (CloudMonitor metrics) are prefixed with AliyunHologres_***. Use the tabs at the top of the page to switch between metric dimensions, such as Hologres real-time data warehouse (compute group) instance metrics. Select a target instance, and then enter a query statement, such as AliyunHologres_connection_count{}, in the Metrics exploration section. A line chart below shows the trend of the metric.

4. In the top navigation bar, select Resource Center. Click the target instance ID to view detailed insights for the entity.

5. Select Metric Explorer to view the metric sets for the current entity.

6. Select a metric set to view its data for the current instance, including trends, anomaly detection, and drill-down analysis.
