Risks, Limitations and Assumptions

  • The applications can critical and recovery failure notifications for the following two cases when the user enables App Failure Notifications in the configuration.
    • Connectivity Exception
    • Authentication Exception
  • The application sends duplicate or repeat failure alert notifications every 6 hours.
  • The application does not control monitoring pause or resume actions based on these alerts.
  • Metrics can be used to monitor HPE Alletra MP B10000 Series resources and generate alerts based on threshold values.
  • Alert polling for HPE Alletra MP B10000 Series starts only when the user enables Alert Polling in the configuration.
  • The app uses available v3 APIs to support alert polling.
  • Component-level thresholds can be configured at the individual resource level.
  • The app does not support:
    • Macro replacement for threshold breach alerts (for example., customizing subject or description).
    • Displaying activity logs or applied time.
    • Application is not compatible with Cluster Gateway.
  • Latest snapshot metric support is available from Gateway version 14.0.0.
  • As per the Developer Guide, support for displaying disk information was added in WSAPI 1.6.15.
  • OpsRamp uses:
    • Physical Disk Statistical Data Reports API when the WSAPI version is less than 1.6.15.
    • Querying Physical Disk Information API when the WSAPI version is greater than or equal to 1.6.15.
  • Due to missing direct name information in WSAPI responses, OpsRamp made the following assumptions: Physical Disk Discovery
    • OpsRamp uses Physical Disk ID as the Resource Name when the WSAPI version is less than 1.6.15.
    • OpsRamp uses WWN as the Resource Name when the WSAPI version is greater than or equal to 1.6.15. Ports Discovery
    • OpsRamp uses portWWN for FCoE and FC ports.
    • OpsRamp uses portPos when portWWN is not present in the response.
      VLUN Discovery
    • OpsRamp uses the lun value as the Resource Name.
  • Possible values for the Alert Severity Filter configuration property:
    • SEVERITY_FATAL
    • SEVERITY_CRITICAL
    • SEVERITY_MAJOR
    • SEVERITY_MINOR
    • SEVERITY_INFO
  • Sample mappings are provided to map HPE Alletra MP B10000 Series severities to OpsRamp severities in the Alert Severity Mapping configuration file.
  • Users can modify these mappings at any time from the app configuration page.
  • Possible OpsRamp severities include:
    • Critical
    • Warning
    • Ok
    • Info
  • The developer guides do not provide information on how logged system events are resolved; therefore, OpsRamp has not included a recovery mechanism for polled events or alerts.
