Risks, Limitations & Assumptions

  • Application handles Critical/Recovery failure alert notifications for the following two cases when user enables App Failure Notifications in configuration.
    • Connectivity Exception
    • Authentication Exception
  • Application sends any duplicate/repeat failure alert notification for every six hours.
  • The application does not control monitoring pause or resume actions based on alerts. Users can monitor Zerto resources and generate alerts by setting threshold values on metrics.
  • OpsRamp sets port 443 as the default for processing ZVM REST APIs. Users can modify this value anytime from the application configuration page if needed
  • Zerto starts event and alert polling only when the user enables Event/Alert Polling in the configuration.
  • The Alert Severity Filter configuration accepts two values: Error and Warning.
  • The Help Identifier Filter configuration uses default values such as ZVM0001, ZVM0002, ZVM0003, ZVM0004, and so on.
  • OpsRamp provides default mappings to align Zerto severities with OpsRamp severities as part of the Alert Severity Mapping configuration. Users can modify these mappings anytime from the application configuration page based on their use case. The possible OpsRamp severities are Critical, Warning, Ok, and Info.
  • Opsramp uses the GET /v1/alerts API for alerts polling functionality and below is the flow of execution.
    • During the first poll request, OpsRamp processes alerts with is_dismissed=false, applies the Alert Severity Filter, Help Identifier Filter, and Alert Severity Mapping configurations to parse and publish critical or warning alerts, and stores their unique identifiers at the application level for use in subsequent monitoring requests.
    • From the second polling onward, the application checks the current API response to determine whether previously polled alerts are healed (i.e., is_dismissed=true) and generates OK alerts accordingly. Similarly, it identifies any new alerts with is_dismissed=false, publishes the corresponding critical or warning alerts, and stores their unique identifiers for use in subsequent monitoring processes.
  • The application does not display the activity log or the applied time.
  • OpsRamp supports the Latest Snapshot Metric option starting from version nextgen-14.0.0.
  • The application supports full discovery only when the gateway version is 15.0.0 or higher.
  • The application does not support Cluster Gateway compatibility.
