`Dameng` Database（DM8）¶

Installation Configuration{#config}¶

Installation DM8
Installation DEM

DEM, also known as Dameng Enterprise Manager, is a web tool provided by Dameng and written based on Java for monitoring Dameng databases.

Directory as $DM_HOME/web, the current directory stores the DEM installation manual (DEM.pdf) and the running program dem.war, and deploy according to the manual.

Metrics¶

The default exposure metric port for DEM is 8090, and the metric related information can be viewed through a browser: http://clientIP:8090/dem/metrics。

DataKit Collector Configuration¶

Because DEM can expose metrics URL directly, it can be collected directly through prom collector.

The adjustments are as follows:

urls = ["http://clientIP:8090/dem/metrics"]
source = "dm"
interval = "10s"

Other configurations are adjusted as needed

, adjust parameter description:

Urls: prometheus Metric address, where you fill in the metric URL exposed by the corresponding component
Source: Collector alias, recommended to distinguish
Interval: collection interval
