Use this page to view health information about the specified NDS®Agent and the partitions and replica rings it participates in. Additional links are provided that give several layers of more detailed information.
Health Check: Agent
One Successful Time Sync
If the agent has never successfully synchronized, no data will appear. Otherwise, the result will always be displayed as green, indicating success.Time Delta Tolerance
The time difference is less than 5 seconds; no warning is displayed.
The time difference is 5 - 10 seconds off; a caution is displayed.
The time is off by more than 10 seconds; a warning is displayed.
DS Loaded
Reports whether the directory is loaded.DS Open
Reports the state of the directory.
- Initial: The agent is attempting to open the database and initialize itself.
- Open: The agent has the database open and is accepting requests.
- Closed: The agent has the database closed and no requests can be accepted.
- DB_Corrupted: The agent attempted to open the database but failed. The database may need to be repaired.
- Could_Not_Open: The agent could not or was requested not to open the database on the loading of the directory.
- Rehashing: The agent is recalculating indexes for improved performance. This is a temporary state and is not used in NDS 8.x.
Health Check: Partition
Partition
Links to detailed object information for each partition being stored on the server. Choosing Replica Synchronization for a partition displays the replica status for each replica in the ring.Description
Allows you to view general information, such as replica counts, for the ring.Results
This is a summary and status of the ring and replica checks. For example, if the Max Send Delta is greater than four hours, or if there are fewer than three readable replicas, a warning is displayed under Results.
Health Check: Ring
Replica Number
Reports whether the replica number is unique and valid.Master Replica
Reports whether there is one and only one Master Replica.Readable Replica Count
Reports whether the number of readable replicas falls within an acceptable range. You should have a least three readable replicas to ensure data integrity.Sub-Reference Count
This number is informational only. The only way to change this count is in the tree design and placement of parent replicas.Total Replica Count
The sum of all replicas.Replica
Provides more information about the all replicas in the ring. If a replica is not On, a partitioning operation may be in process. A warning is displayed if the operation state hasn't changed within 4 hours.
