It consists of the collector description, metric set, and collection parameters. Collector description describes the data collected by a collector. Metric set is the data collected according to specifications. Collection parameters are the custom data to be collected.</p>

For example, Java performance data is collected by JavaAgents. The data collected by APM Agents must correspond to the data models of collectors' metric sets so that servers can process the data.</li><li id="apm_07_0031__en-us_topic_0000001087028667_li1942111782210">The Agent of each language and framework defines its own collector.</li><li id="apm_07_0031__en-us_topic_0000001087028667_li161994916515">After a collector is added to an environment, it is instantiated as a monitoring item. This process is generally automated. APM Agents automatically discover collection plug-ins used by applications and add collectors to the environment to form monitoring items. For example, if a Java application connects to a database through the JDBC driver for MySQL, the MySQL collector is automatically added to the environment to form a monitoring item.</li></ul>

You can modify collection parameters on the page as required. These parameters will be delivered to Agents with heartbeat parameters to change collection behaviors. By default, Redis instruction content is not collected for security purposes. If necessary, modify collection parameters to collect specific instruction data. Collection parameters can also be defined on environment tags. Collectors automatically inherit collection parameter attributes of corresponding environment tags. In this way, configuration is automated. For details about how to set collection parameters, see <a href="apm_07_0011.html#apm_07_0011">Application Monitoring Configuration</a>.</p>
