+# 4、Monitor metrics configuration instructions
+
+ DataProxy provide monitor indicator based on JMX, user can implement the
code that read the metrics and report to user-defined monitor system.
+Source-module and Sink-module can add monitor metric class that is the
subclass of org.apache.inlong.commons.config.metrics.MetricItemSet, and
register it to MBeanServer. User-defined plugin can get module metric with JMX,
and report metric data to different monitor system.
+
+ User can describe the configuration in the file "common.properties ". For
example:
+
+ metricDomains=DataProxy
+
metricDomains.DataProxy.domainListeners=org.apache.inlong.dataproxy.metrics.prometheus.PrometheusMetricListener
+ metricDomains.DataProxy.snapshotInterval=60000
+
+ * The JMX domain name of DataProxy is "DataProxy".
+ * It is defined by the parameter "metricDomains".
+ * The listeners of JMX domain is defined by the parameter
"metricDomains.$domainName.domainListeners".
+ * The class names of the listeners is separated by the space char.
+ * The listener class need to implement the interface
"org.apache.inlong.dataproxy.metrics.MetricListener".
+ * The snapshot interval of the listeners is defined by the parameter
"metricDomains.$domainName.snapshotInterval", the parameter unit is
"millisecond".
+
+ The method proto of org.apache.inlong.dataproxy.metrics.MetricListener is:
+
+ public void snapshot(String domain, List itemValues);
+
+ The field of MetricItemValue.dimensions has these key(The fields of
DataProxyMetricItem defined by the Annotation "@Dimension"):
+
+ public String clusterId: DataProxy cluster ID.
+ public String sourceId: DataProxy source component name.
+ public String sourceDataId: DataProxy source component data
id, when source is a TCP source, it will be port number.
+ public String inlongGroupId: Inlong data group ID.
+ public String inlongStreamId: Inlong data stream ID.
+ public String sinkId: DataProxy sink
component name.
+ public String sinkDataId: DataProxy sink
component data id, when sink is a pulsar sink, it will be topic name.
Review comment:
fixed, remove 'public String' and format it.
