An AppDynamics extension to be used with a stand alone Java machine agent to provide metrics for Dropwizard
Dropwizard is a Java framework for developing ops-friendly, high-performance, RESTful web services. Dropwizard pulls together stable, mature libraries from the Java ecosystem into a simple, light-weight package that lets you focus on getting things done. Dropwizard has out-of-the-box support for sophisticated configuration, application metrics, logging, operational tools, and much more, allowing you and your team to ship a production-quality web service in the shortest time possible.
We will be reporting various measuring instruments that DropWizard Metrics provides. For more detailed metrics, refer:/
In addition to the metrics exposed by Confluence, we also add a metric called "Metrics Collection Successful" with a value 0 when an error occurs and 1 when the metrics collection is successful.
Note : By default, a Machine agent or a AppServer agent can send a fixed number of metrics to the controller. To change this limit, please follow the instructions mentioned here. For eg.
java -Dappdynamics.agent.maxMetrics=2500 -jar machineagent.jar
<MachineAgent_Dir>/monitors/DropWizardMonitorand update the following details. Comment out properties which are not used
metricPrefix: To report the metrics only to a given Tier, use the second one instead. The TIER_ID can be found from the REST API
metricPrefix: Custom Metrics|DropWizard #metricPrefix: Server|Component:<TIER_ID>|Custom Metrics|DropWizard
#Dropwizard Health Metric URL path servers: - uri: http://<<dropwizard_host>>:<<health_metrics_port>>/metrics displayName: metrics
Metrics: These are the metrics collected from DropWizard and reported to controller.
##Dropwizard Metrics metrics: - meters: - displayName : "Logback|M1Rate|All" path : "ch.qos.logback.core.Appender.all" type: "OBS.CUR.COL" . . . .
Workbench is a feature that lets you preview the metrics before registering it with the controller. This is useful if you want to fine tune the configurations. Workbench is embedded into the extension jar.To use the workbench
java -jar /path/to/MachineAgent/monitors/DropWizard/DropWizardMonitor.zipThis starts an http server at
http://host:9090/. This can be accessed from the browser.
#Get the stats curl http://localhost:9090/api/stats #Get the registered metrics curl http://localhost:9090/api/metric-paths
config.ymland validate it from the browser or the API
The metrics will be reported under the tree
