• Health Monitoring Service
  The Health Monitoring service notifies you about potential issues concerning the connection between the HMC and CMC, or the reporting of performance data for systems being monitored by CMC. A notification appears in the notifications panel, and the service sends you a notification (phone, email) based on your notification panel settings. All Health Monitoring Service notifications are repeated on 24-hour intervals until the issue has been resolved.
  
  The service notifies you of the following issues:
  • Inactive HMCs. A list of all HMCs that have been inactive for more than 60 minutes.
  • Disconnected EP 2.0 systems. The possible disconnected system states that are notified are as follows:
    • No connection
    • Pending authentication
    • Failed authentication
    • Version mismatch
    • Disconnected (EP 2.0 state)
  • EP 2.0 systems with Performance and Capacity Monitoring (PCM) disabled.
  • Systems in the inventory that stopped reporting performance data for more than 60 minutes.
    
    
• As noted in the previously released March hotfix, for email notifications on the notification panel, the sender identity has changed from "[e-mail]" to "[e-mail]." You may need to make changes in your environment if you have made accommodations for the previous sender identity.
  
  It is recommended that you perform a test email to confirm the receipt of the message from the new sender identity, and to ensure that it is not blocked by your email system.
  
  To do this:
  1. Click the Notifications () icon.
  2. Select the app.
  3. Click the Settings  () icon. 
  4. On the In-App Notification page, enter your email address and click Test Email and Text.
