Alarm Notification Types

Reference Number: AA-02142 Views: 120 0 Rating/ Voters

When enabled, the LumenVox Manager can send a number of different types of SNMP Trap notifications.

These notifications are typically messages or alerts to indicate some change in state of some monitored object, or a heartbeat message to indicate that the LumenVox Manager is still running. These Trap notifications are sent to all configured TRAP_SERVERS using SNMP v2c protocol.

Here is a complete list of the Types of Trap message that can be generated by LumenVox:

  
  

Trap Type

  
  

Description

  
  

lvAlarmHeartbeat

  
  

This message type is sent to all registered  TRAP_SERVERS at the specified HEARTBEAT_INTERVAL. When this HEARTBEAT_INTERVAL  is set to 0 (the default), no heartbeat messages will be sent.


This notification type is sent with INFO severity  and does not include a CorrelationID field (since it is not an alarm or a  clear notification). A count of the current heartbeats sent is sent within  the lvTrapAdditionText field.


Specified TRAP_SERVERS can be configured to expect  these trap notifications, and if no heartbeat is received within a certain  time period, this can be used to indicate a failure of the LumenVox server,  or LumenVox Manager Service – either of which should be investigated.

  
  

lvAlarmCpuOverload

  
  

There are 3 thresholds (MINOR, MAJOR and CRIT) that  can be defined for this type of alarm (in manager.conf). When system CPU  utilization exceeds one of the specified thresholds, the corresponding trap  notification will be sent with the appropriate severity.

  
  

lvAlarmCpuAbate

  
  

Sent when the corresponding lvAlarmCpuOverload alert  has abated – when system CPU use has fallen below the specified threshold.

  
  

lvAlarmMemoryOverload

  
  

There are 3 thresholds (MINOR, MAJOR and CRIT) that  can be defined for this type of alarm. When system memory utilization exceeds  one of the specified thresholds, the appropriate corresponding trap  notification will be sent with the appropriate severity.

  
  

lvAlarmMemoryAbate

  
  

Sent when the corresponding lvAlarmMemoryOverload  alert has abated – when system memory use has fallen below the specified threshold

  
  

lvAlarmCommsFailure

  
  

When communication with one of the configured LumenVox  services is lost, an alert of this type will be generated.


If the service is designated as the Primary (first  listed) instance, then a message will indicate this.


Also, if alternate servers of this type remain available,  this will be indicated, as well as affect the notification severity. When alternate(s)  are available, the message will have MINOR severity. When no alternate is available,  the message will have CRIT severity.

  
  

lvAlarmCommsRestore

  
  

Sent when the corresponding lvAlarmCommsFailure  alert has been removed – when the communication link is restored.

  
  

lvAlarmNoLicense

  
  

This message is generated whenever an attempt to  request ASR or TTS licenses is made by the Media Server service.


The notification will indicate whether the failure  was due to a TTS license request or an ASR license request. The message severity  will be CRIT

  
  

lvAlarmLicenseAvailable

  
  

Sent whenever the corresponding lvAlarmNoLicense  alert has cleared – once a request for the appropriate ASR or TTS license  type has succeeded.

  
  

lvAlarmLowLicenseAlert

  
  

This is not implemented in the current version (for  future use)

  
  

lvAlarmLowLicenseAbate

  
  

This is not implemented in the current version (for  future use)

  
  

lvAlarmLowDiskSpaceAlert

  
  

There are 3 thresholds (MINOR, MAJOR and CRIT) that  can be defined for this type of alarm.


When free disk space drops below one of the specified  thresholds, the appropriate trap notification will be sent with the  corresponding severity.


Note that the disk drive / partition being  monitored is the one associated with the LumenVox Manager’s LVLOGS folder –  wherever the manager’s logs are stored. We recommend that systems are  configured to store their log files to the same disk / partition for all  LumenVox services to avoid any confusion, since only this disk/partition is  monitored.

  
  

lvAlarmLowDiskSpaceAbate

  
  

These messages will be sent when the corresponding  lvAlarmLowDiskSpaceAlert alert has abated – whenever free disk space has been  raised above the specified threshold.

  


Note that these trap alert types are defined within the LUMENVOX-SNMP-MIB definition document that can be imported into many standard SNMP systems. The definition of these notifications is shown here:


See the Trap Message Contents article for additional information about the structure of Variable Bindings that are sent within these notification messages.
