How to Enable Monitoring? #

The host monitoring function needs to pass through Prometheus’ node_ exporter, and the agent module of SphereEx Enterprise Data Service Platform achieves compute node monitoring.

Requirements

Before enabling the monitoring function:

• Please confirm that node_exporter is running on the monitoring host. a. Download the corresponding node_ exporter component according to the operating system, download address: https://prometheus.io/download/ . b. Unzip the node_ exporter installation package, and execute command ./node_exporter to start.
• Please ensure that the agent function is enabled on the compute node. Refer to https://shardingsphere.apache.org/document/current/en/user-manual/shardingsphere-proxy/observability/ for relevant operations.

Procedure

1. Install and start Prometheus. Assume that the operation address is 192.168.1.100 and port 9090.
2. Configure monitoring objectives.

Caution: Modify the Prometheus configuration file prometheus.yml, add the host, compute node IP and port in the static_configs.targets under scrape_configs node. You need to use the actual IP address of the host and compute node, not 127.0.0.1, localhost and other local addresses.

Suppose the access address of node_exporter of the monitoring host is 192.168.1.100:9100, and the running address of the Prometheus plugin in the agent module of the compute node is 192.168.1.100:9000.

 static_configs:
   - targets: ["192.168.1.100:9100", "192.168.1.100:9000"]

3. Configure the Prometheus address in application.properties. prometheus.server.address=http://192.168.1.100:9090
