Registered Secure Email Proxies check in with Mobility Manager on a regular basis and report their status. You can monitor your proxy status from Mobility Manager.
Proxy health is color-coded as follows:
The proxy is registered, but it is not assigned to a cluster.
The proxy hasn't checked in for more than 10 minutes.
The proxy hasn't checked in for more than 30 minutes. This could also mean that the proxy has experienced a failure applying configuration updates or applying policies. Mobility Suite might have also detected the proxy processes are not running.
If the email proxy can't communicate with Mobility Manager, a user's ability to access email is based on the last known device policy. Important: Access is allowed during this time even if the device becomes non-compliant. But users who are blocked email access continue to be blocked. After the proxy restarts, users are allowed/blocked access based on the most current device policy. In the Clusters section, click on your proxy to view status and health messages:
Monitor the health of your proxies
Click Settings > Email Proxy.
In the Available Clusters table or the Available Proxies list, click on the name of the proxy you want to see more information about.
Details about that proxy along with all of the other proxies in the cluster appear. This information includes the date and time of the last check-in, the status of the proxy, and any available information about the proxy.
For additional information, check the proxy logs.
By default, the proxy logs are in the following location:
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:
