Monitoring Redundancy and Failover
The following tools are available to monitor your redundant RSMs and the failover process:
- The CygNet Redundancy Dashboard shows every service in your system, on which domain it is running, and if it is standby mode, whether or not it’s ready to become the active service. Other key pieces of information available on the dashboard include each service's status, the direction and status of replication, the system's readiness to execute local failover, and the system's readiness to execute data-center failover.
- Redundancy and Failover Info Items. See Redundancy and Failover Info Items for a list of the SVCMON points that can be created to monitor Redundancy and Failover Info Item values.
- The RSM Diagnostic Tool verifies the consistency of redundancy definitions and services and their owners across RSMs in a redundancy environment.
- The ARS Diagnostic Tool provides administrative statistics on Address Resolution Services (ARS) for advanced administrators, integrators, and CygNet support. It can be used to monitor time synchronization across multiple domains in a redundant environment.
-
The FailoverEventLog.log file found in the RSM folder for every redundant site logs the failover process and can be used to troubleshoot problems. This file is persisted between failover events, providing a historical record that exists beyond the last failover. A new file is created when the FailoverEventLog.log reaches 1MB and a maximum of five files are retained.
The master RSM in the redundancy environment audits and logs several details about each failover event, including:
- the type of failover (Hard or Soft)
- the list of services being failed over
- start and end of a failover sequence
- the status of the failover (Uninitialized, In Progress, Succeeded, Failed)
- the user who initiated the failover
- any failover comment entered by the user
