Citrix NetScaler is an all-in-one web application delivery controller (ADC) that makes applications run up to five times faster, cuts web application ownership costs with server offloading, and makes sure that applications are always available with its application load balancing capabilities.
NetScaler VPX provides the complete NetScaler web and application load balancing, secure and remote access, acceleration, security and offload feature set in a simple, easy-to-install virtual appliance.
The AppDynamics monitoring extension for NetScaler provides metrics collected by the NetScaler appliance about the usage of its features and corresponding resources using the NITRO API. These metrics can be classified under the following groups:
Core System Metrics
Service Resource metrics
Load Balancing metrics
The extension needs to be able to connect to the NetScaler NITRO API in order to be able to collect and send the metrics. To do this, you will have to either establish a remote connection in between the extension and the product, or have an agent on the same machine running the product in order for the extension to collect and send the metrics.
The NetScaler extension connects to the Citrix Netscaler appliance using the NITRO REST API.
