We utilize Cisco Meraki System Manager (MDM) for our customer's iPads. As part of the deployment process you must get an "Apple Push Notification service" (APNs) certificate. Monitoring this certificate is very important, because if you don't renew it before it expires then you have to wipe and redeploy the MDM on your fleet of iPads.

Have the inspector grab info about the APNS cert in use, including it's expiry date. Make a metric for it so we can set up alerts/tickets as the expiration date draws near.
