Monitoring Secure Email Proxy usage with telemetry
You can use telemetry to monitor Secure Email Proxy usage. For example, you can monitor the number of active connections to your proxy to help you assess when you should deploy another proxy to balance the load. Telemetry also provides data on the number of connection requests that are blocked, allowed, or able to pass directly through to your Exchange ActiveSync Server (EAS). This data is information that you can use for troubleshooting.
Telemetry is automatically enabled when you install or upgrade to Secure Email Proxy 5.0. Data is collected approximately every minute. The most recent 10 minutes worth of data is stored in a .json file (with each minute organized into a timebucket) on your proxy server. Every minute, a new timebucket is added to the .json file while the oldest timebucket (created 11 minutes ago) is purged.
Telemetry measures the activities of the nginx application and the controller application. The nginx application communicates proxy requests from the device to the Exchange infrastructure. Whereas the controller application communicates with Mobility Manager, providing a link between the proxy and Mobility Manager. Typically, administrators focus on nginx values that they can use to graph connection usage.
The following is an example of what a single timebucket in a formatted .json file would look like:
