While configuring JMX-based extensions, you may sometimes face connectivity issues to your application server which is exposed via JMX. You may also want to verify a metric value reported by extensions against the value reported in JConsole for the same attribute and MBeans.    To perform any of these tasks, see the detailed description provided in the How do I use JConsole to test and troubleshoot connectivity Knowledge Base article.   The recommended practice is to run the JConsole on the same server where you are running the machine agent with a JMX-based monitor, and using the same user which is running the agent. ...

The Controller has various metric processing qualifiers with regard to aggregation, time roll-up, and cluster roll-up, for processing a metric. These qualifiers are configured for each metric that an extension reports. Please refer to the Build a monitoring extension using Java documentation for details on various metrics processing qualifiers supported by the Controller.   Your extension can have metric configurations in either the  config file or the  metric file.   Contents When my metric configurations are provided in config.yml file When my metric configurations are provided in metrics.xml file When there are no configured qualifiers for metrics in the extension   When my metric configurations are provided in the config.yml file Sometimes you will see that an extension has metric configurations in the config.yml file.    Sample configuration for metric configuration in the config file:     - name: “numTasks” alias: “Num Tasks” #Number of tasks in the application multiplier: “1" aggregationType: “AVERAGE” timeRollUpType: “AVERAGE” clusterRollUpType: “INDIVIDUAL” delta: “false”       You can modify any of the metric processing qualifiers to one of the supported values of its category  and metrics will follow the same aggregation and roll-up strategy on the Controller. For additional details on the metric processing qualifiers supported by the Controller, refer to Metric Processing Qualifier in the Extensions and Custom Metrics section of the documentation. Back to Contents   When my metric configurations are provided in the metrics.xml file Some of the extensions support the processing of metrics from the  metrics.xml file.    Sample configuration in metrics.xml file:     <metric attr="Received" alias="Received" aggregationType = "AVERAGE" timeRollUpType = "AVERAGE" clusterRollUpType = "INDIVIDUAL"/>       In the metrics.xml file, you can modify any of these aggregation or roll-up parameters to supported value, and the same will be followed on the Controller.   When there are no configured qualifiers for metrics in the extension In some cases, you may see that there are no qualifiers configured for metrics in the extension.    In such a case, default values are assigned to these qualifiers:  Qualifier Assigned Default Value “aggregationType” “AVERAGE” “timeRollUpType” “AVERAGE” “clusterRollUpType” “INDIVIDUAL” Back to Contents ...

Troubleshooting various kinds of AWS extensions issues Following are some of the troubleshooting steps for AWS extensions:   Contents How do I troubleshoot connectivity issues for AWS extensions? How do monitoring type settings affect AWS extensions? What should I consider about metrics querying window settings? Where can I find advanced extension configuration and troubleshooting information? Additional resources   How do I troubleshoot connectivity issues for AWS extensions? If you are facing connectivity issues for your AWS extensions, then you can try executing the “ get-metric-statistics ” call from the same host using AWS CLI.    You can install AWS CLI on the host where your Machine Agent with AWS extension is running. Once you have installed and configured AWS CLI, you can execute the “ get-metric-statistics ” call to test connectivity.   For AWS CLI installation details, follow Installing, updating, and uninstalling the AWS CLI documentation. For details on how to execute the “ get-metric-statistics ” call from the CLI, refer to AWS’ Get metric statistics documentation.   NOTE | that AWS extension does not support Assume roles-based authentication.   How do monitoring type settings affect AWS extensions? Verify that type of monitoring enabled on cloudwatch for a service is the same monitoring type enabled in your AWS extension. You can enable “Basic” or “Detailed” monitoring by configuring the following flag in the extension's config file.   cloudWatchMonitoring: "Basic"   “Basic” monitoring will fire CloudWatch API calls every 5 minutes. On the other hand, “Detailed” monitoring will fire CloudWatch API calls every 1 minute.  By default, “Basic” monitoring is enabled for all AWS extensions.   What should I consider about metrics querying window settings? Sometimes after providing all configurations correctly, you may observe that metrics for AWS extension are still not visible on the controller.    One reason for this could be because there is no metrics data available in AWS cloudwatch during the configured time range. The “ metricsTimeRange ” property defines the “ startTimeInMinsBeforeNow ” and “ endTimeInMinsBeforeNow ” and can be modified depending on when the data is available in cloudwatch.   metricsTimeRange:       startTimeInMinsBeforeNow: 10       endTimeInMinsBeforeNow: 0   The “ startTimeInMinsBeforeNow ” cannot be less than the “ endTimeInMinsBeforeNow ” or the extension will generate errors.   Where can I find advanced extension configuration and troubleshooting information? The Advance extension configuration and troubleshooting Knowledge Base article contains detailed information related to features provided by AppDynamics Extensions. It  can help you troubleshoot your extension and become more informed on how to use different functionalities provided through the various groups of extensions.    NOTE | Not all features are available for every extension.  ...

How can I avoid extension errors due to unconfigured (or incorrectly configured) health check parameters?   The Java SDK for AppDynamics Extensions runs a few checks to validate the Application and Machine Agent configuration. However, there are few errors (like too many open files, high cpu usage, or huge agent log file sizes) that could arise if correct configurations for these health check parameters are not provided in the extension’s config.    Following are some exceptions related to health checks which are reported in Machine Agent logs. Exception when running   com.appdynamics.extensions.checks.ExtensionPathConfigCheck@58cd7f75 com.appdynamics.extensions.checks.MachineAgentAvailabilityCheck@754f1f01   Therefore, we recommend keeping the " enableHealthChecks " flag disabled from the config.yml file. Disabling health checks will not obligate metrics collecting and reporting by the extension.   To disable health checks , you can configure the flag below and set it to “false” in the config file: enableHealthChecks: false   If the enableHealthChecks flag is not configured by default in the extension's config, then add the flag at root level, in a new line without any spaces. Find more details on extensions health checks in the  What extension Health Checks are useful for debugging? Knowledge Base article. ... View more
