The following table lists the Double-Take SNMP statistics.
dtActFailCount
The number of activation code errors
dtAutoDisCount
The number of auto-disconnects
dtAutoReCount
The number of auto-reconnects
dtconBytesCompressedTx
The total number of compressed bytes transmitted to the target
dtconBytesInMirQueue
The number of mirror bytes in the queue
dtconBytesInRepQueue
The number of replication bytes in the queue
dtconBytesRx
The total number of bytes received by the target
dtconBytesTx
The total number of bytes transmitted to the target
dtconConnectTime
The length of time, in seconds, that the connection has been active
dtconIpAddress
The IP address of the connected machine. If you are on the source, then this will be the IP address of the target. If you are on the target, then this will be the IP address of the source.
dtConnectionCount
The number of active connections between servers
dtconOpsInAckQueue
The number of operations (create, modify, or delete) waiting for verification acknowledgements from the target
dtconOpsInCmdQueue
The number of operations (create, modify, or delete) in the queue on the source
dtconOpsInMirQueue
The number of mirror operations (create, modify, or delete) in the queue on the source
dtconOpsInRepQueue
The number of replication operations (create, modify, or delete) in the queue on the source
dtconOpsRx
The total number of operations (create, modify, or delete) received by the target
dtconOpsTx
The total number of operations (create, modify, or delete) transmitted to the target
dtconResentOpCount
The number of operations that were resent because of acknowledgement errors
dtconState
The state of the active connection
0—None. This indicates there is no active connection. This may be because the connection has not been established or the underlying connection is unavailable. Statistics are still available for the source and target machines.
1—Active. This indicates that the connection is functioning normally and has no scheduling restrictions imposed on it at this time. (There may be restrictions, but it is currently in a state that allows it to transmit.)
2—Paused. This indicates a connection that has been paused.
4—Scheduled. This indicates a connection that is not currently transmitting due to scheduling restrictions (bandwidth limitations, time frame limitations, and so on).
8—Error. This indicates a connection that is not transmitting because something has gone wrong (for example, lost connection).
Only the Scheduled and Error states can coexist. All other states are mutually exclusive. SNMP will display a dtconState of 12 when the connection is in both a scheduled and an error state because this is the sum of the two values (4 + 8).
dtCurrentMemoryUsage
The amount of memory, in bytes, allocated from the Double-Take memory pool
dtCurrentMemoryUsageMB
The amount of memory, in MB, allocated from the Double-Take memory pool
dtDriverQueuePercent
The percentage of the driver queue that is currently in use. (This is the amount of throttling calculated as a percentage of the stop replicating limit.)
dtFailedLoginCount
The number of unsuccessful logins
dtFailedMirrorCount
The number of operations that failed to mirror because they could not be read on the source
dtFailedRepCount
The number of operations that failed to be replicated because they could not be read on the source
dtLoginCount
The number of successful logins and logouts
dtMirBytesGenerated
The number of mirror bytes transmitted to the target. This is the number of bytes generated during mirroring. In other words, this is roughly the amount of traffic being sent across the network that is generated by the mirror. It does not take into account TCP/IP overhead (headers and such), however it does account for attributes and other overhead associated with creating a file. With many small files in a directory, you will see larger statistics than expected because of the file creation overhead. Any subsequent remirror will reset this field to zero and increment from there.
dtMirOpsGenerated
The number of mirror operations (create, modify, or delete) that have been generated by the mirroring driver
dtOpsDroppedCount
The number of file operations that have failed and will not be retried
dtRepBytesGenerated
The number of bytes generated by the replication driver
dtRepOpsGenerated
The number of operations (create, modify, or delete) that have been generated by the replication driver
dtRetryCount
The number of file operations that have been retried
dtSourceState
0—Source is not running
1—Source is running without the replication driver
2—Source is running with the replication driver
dtTargetState
0—Target is not running
1—Target is running
dtUpTime
The time in seconds since Double-Take was last started
