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.
