Hi Manoj,
You can just comment it out if you have the encryptedPassword defined.
Thanks

Hi Konrad,
As of now, we don't have any plans to enforce encryption. But yes, since it is going to be part of our library, vendors can always use it.
Thanks

What are the possible configuration scenarios for the Machine Agent and SIM and App Agents, and their impact on an extension and its configurations?
Table of Contents
APM Machine Agent Installation
Independent Machine Agent Installation
Server Infrastructure Monitoring (SIM) with No App agents
Server Infrastructure Monitoring (SIM) with one or more app agents
APM Machine Agent Installation
This case is when a Machine Agent (MA) is configured on the same host as one or more App Agents. For more details, please check APM Machine Agent Installation Scenario.
In this case, if app, tier and node names are NOT specified in the MA configuration, the MA will be resolved to all the APM app, tier and node associated on that host. So, if in the extension's configuration metricPrefix is configured as metricPrefix="Custom Metrics|Sample Monitor" all the Custom Metrics from the extension will be replicated under all the APM metric browsers associated to that host.
If the requirement is to see the Custom Metrics under a particular application only, this can be done by specifying metricPrefix = "Server|Component:<ID or Name>|Custom Metrics|Sample Monitor"
To find the Component ID, please refer to Configuring an Extension. In this case, the Custom Metrics from the extension will show up only in the Metric Browser of the application to which the Component ID (tier) belongs.
IMPORTANT: The Component ID specified in the metric prefix of the extension should match to one of the resolved tiers of the MA. The extension cannot report to any tier other than any of the resolved tiers of its MA.
Independent Machine Agent Installation
An independent Machine Agent without any APM Agents is not supported by AppDynamics. There have to be App Agents running on the same host for the Machine Agent to run in standalone mode. If the requirement is to use extensions without any APM Agents, a Server Visibility license needs to be purchased. Please check the SIM with No App agents scenario.
Server Infrastructure Monitoring (SIM) with No App agents
In this case, metricPrefix should be configured as metricPrefix = "Custom Metrics|Sample Monitor"
However, as mentioned in the APM Machine Agent Installation Scenario, if the requirement is to see the Custom Metrics from the extension under a particular application only, this can be done by following the steps mentioned below:
1. The app, tier and node name need to be specified in the controllerInfo.xml.
2. In the extension's configuration, the metricPrefix should be configured as
metricPrefix = "Server|Component:<ID or Name>|Custom Metrics|Sample Monitor"
IMPORTANT: The component ID specified in the metric prefix of the extension should match to the tier specified in the controller-info.xml. The extension cannot report to any tier other than the tier pointed by the SIM agent.
Server Infrastructure Monitoring (SIM) with one or more app agents
In this case, metricPrefix should be configured as metricPrefix = "Custom Metrics|Sample Monitor"
All the Custom Metrics from the extension will be replicated under all the APM metric browsers associated to that host. If the requirement is to see the Custom Metrics under a particular APM application only, this can be done by specifying:
metricPrefix = "Server|Component:<ID or Name>|Custom Metrics|Sample Monitor"
To find the Component ID, please refer to Configuring an Extension. In this case, the Custom Metrics from the extension will show up only in the Metric Browser of the application to which Component ID (tier) belongs.
IMPORTANT: The host ID field helps the Controller to stitch the metrics from the Machine Agent or SIM Agents and App Agents together. This host ID field, by default, has the system hostname value. However, this can be overridden by using the uniqueHostId field on the agents.

AppDynamics extensions are divided into two broad categories: Monitoring extensions and Alerting extensions.
Monitoring Extensions
These extensions run as monitors on AppDynamics Machine Agent and report metrics from an artifact to AppDynamics Controller.
Examples of these are Cassandra Extension and Memcached Extension.
A guide to building monitoring extensions using Java and Shell Scripts can be found in the product documentation here and here respectively.
Alerting Extensions
These extensions are integrations that run as custom actions on the AppDynamics Controller.
Most of these alerting extensions work only for dedicated (single-tenant) SaaS Controller or on-premises Controllers.
Please refer to HTTP Request Actions and Templates.
Find more information in the AppDynamics Exchange.
