Replication Alerts

Alerts are posted when any of the following replication events occur:

• A manual or scheduled replication update starts or finishes successfully (both source and target).

• Any replication update fails, including explicit cancellation by an administrator (both source and target).

• A scheduled replication update is skipped because another update for the same action is already in progress.

• A continuous replication starts for the first time, fails, or resumes after a failure.

• A replica time lag exceeds its specified threshold.

To view alerts in the BUI, go to Maintenance > Logs > Alerts.

To view alerts in the CLI, enter maintenance logs, and then enter select alert. Enter show to list the alerts.

hostname:> maintenance logs
hostname:maintenance logs> select alert
hostname:maintenance logs alert> show

Send Finish Alerts

When the system finishes replicating to a target, an alert appears at the top of the BUI window, providing statistics about the most recent replication update:

In the CLI, the completed replication update is reflected in the update statistics, as shown in the following table:

Table 136  Replication Update Statistics (CLI Read-Only)

Property Description logical_bytes Number of bytes that the replication update data stream would have contained if the data on disk had not been compressed and without any subsequent compression or deduplication. phys_bytes Number of bytes in the internal replication data stream prior to replication deduplication or replication data stream compression. to_network Number of bytes that the replication data stream compression pipeline delivered to the network. This shows the consequence of replication data stream compression, if enabled. duration Total time required to perform the replication update.

These replication send finish alerts are also recorded in the system's Alert Log.

Deduplicated Replication Finish Alerts

Alerts for deduplicated replication streams provide additional deduplication statistics.

Table 137  Deduplicated Replication Update Statistics

Property Description after_dedup Number of bytes in the internal replication data stream after any deduplication of the replication data stream. dd_table_build Time spent building the deduplication tables prior to the actual transmission of the replication update. dd_table_mem Maximum amount of memory that was consumed by the deduplication tables.
