replication (instance statistics)
Selecting the replication resource will display a list of available downstream replication instances used by this instance of AMPS.
Selecting an individual replication instance will display the following statistics:
| Metric | Description | Type |
|---|---|---|
authenticated_id | The ID used to authenticate this connection. | fixed |
bytes_out | Number of bytes sent to this destination. | cumulative |
bytes_out_per_sec | Rate of bytes sent. | interval average |
client_name | The client name used for this destination. | fixed |
client_type | Specifies whether client is a replication source or destination. | fixed |
connect_time | Time connected to this destination. | snapshot |
destination_admin_addr | The admin address of the destination. | fixed |
destination_group_name | The group name of the destination. | fixed |
destination_name | The name of the destination. | fixed |
disconnect_count | Number of times replication destination has been disconnected. | cumulative |
disconnect_time | Timestamp of the last time the replication destination disconnected. | snapshot |
is_connected | Boolean telling whether replication destination is currently connected. | snapshot |
messages_out | Number of messages sent to this destination. | cumulative |
messages_out_per_sec | Rate of messages sent to this destination. | interval average |
name | Name of replication configuration. | fixed |
pass_through | Boolean stating whether messages received via replication can be forwarded on this connection. | fixed |
replication_type | One of either sync or async. | snapshot |
seconds_behind | The current point in the transaction log that has been acknowledged by this destination. This is calculated as the difference in seconds between the time that the last message acknowledged by the destination was written to the transaction log and the time that the most recent transaction was processed. That is, if the last message that the destination has acknowledged was written to the local transaction log at AMPS rounds any value below | snapshot |

The replication resource also provides options for managing replication instances. The following management functions are available:
| Element | Description |
|---|---|
downgrade | Change the replication type of this connection from sync to async. |
reconnect | Close and reopen the connection to the remote instance. |
