Sending Email Alert Messages

An alert message is an email that the Vocera Voice Server can optionally send to notify you about events in your system.

These include:

• The amount of free disk space on the Vocera Voice Server drive is less than or equal to 3000 megabytes (the default threshold set as the value of SysFreeDiskSpaceWarningThreshold in \vocera\server\properties.txt.)

• The Vocera Voice Server stopped because the amount of free disk space is less than or equal to 1500 megabytes (the default threshold set as the value of SysFreeDiskSpaceStopThreshold in \vocera\server\properties.txt.)

• The memory in use is within 100 megabytes of the maximum amount of heap memory Java can allocate from the operating system.

• The Vocera Voice Server restarted because the amount of memory in use is within 50 megabytes of the maximum amount of heap memory Java can allocate from the operating system.

  Note: This is a fast restart that releases memory and allows the system to continue running without causing a failover.

• The active node of a Vocera cluster failed, resulting in a failover.

• One of the standby nodes of a Vocera cluster failed.

• The number of logins exceeds 90% of the login license limit (if there is one). One email alert is sent each day the login license threshold is exceeded. The 90% (.90) threshold is the default value of SysLoginLicenseAlertThreshold in \vocera\server\properties.txt.

• The Vocera license is within 5 days of its expiration date. You receive an additional warning each day until the license is renewed or expires.

• The Vocera Voice Server stopped running because its license expired.

• The Vocera Voice Server is unable to connect to the Vocera SIP Telephony Gateway, or Vocera Client Gateway, whether it is a single server or a member of an array.

• The Vocera Voice Server reconnected to a Vocera SIP Telephony Gateway.

• The Vocera Voice Server was unable to establish a connection to the Active Directory. By default, another email alert is sent every 30 minutes until the connection is successful.

• The Vocera Voice Server connection to the Active Directory went down.

• The Vocera Voice Server connection to the Active Directory has switched from a primary server to a secondary server. You may need to take corrective action to ensure that a primary Active Directory server is running and is accessible over the network. By default, another email alert is sent every day until the connection to a primary server is successful.

• The Staff Assignment application changed a department or subdepartment group to an ordinary group. This alert is for information purposes only. Corrective action may not be necessary.

Each email alert includes general information about the Vocera Voice Server, including the IP address of the host, Vocera cluster members, when the alert was generated, to whom the
