Once you’ve integrated with AWS CloudWatch, you have access to all metrics for Database Migration Service, which can help you migrate database and analytics workloads to AWS.

All available AWS integrations

You can validate that metrics are reporting to Lightstep on the Metrics details page in Project settings.

The following table shows the Database Migration Service metrics ingested by Lightstep.

Metric Name Unit Description
aws.databasemigration.available_memory bytes An estimated amount of memory available for starting new applications, without swapping.
aws.databasemigration.cpu_allocated percent The maximum CPU percent that can be allocated for a task.
aws.databasemigration.cpu_utilization percent The percent of allowed vCPU.
aws.databasemigration.disk_queue_depth count The number of waiting disk I/O operations (read/write).
aws.databasemigration.free_storage_space bytes The amount of free storage.
aws.databasemigration.free_memory bytes The amount of physical memory free for applications, page cache, and kernel data structures.
aws.databasemigration.freeable_memory bytes The amount of free RAM.
aws.databasemigration.memory_allocated megabits The maximum allocation of memory for the task. (0 is unlimited)
aws.databasemigration.write_iops count/second The average disk write operations per second.
aws.databasemigration.read_iops count/second The average disk read operations per second.
aws.databasemigration.write_throughput bytes/second The average amount of data written to disk per second
aws.databasemigration.read_throughput bytes/second The average amount of data read from disk per second.
aws.databasemigration.write_latency milliseconds The average time taken per disk write operation.
aws.databasemigration.read_latency milliseconds The average time taken per disk read operation.
aws.databasemigration.swap_usage bytes The amount of swap used on the replication instance.
aws.databasemigration.network_transmit_throughput bytes/second The amount of outoging network traffic on the replication instance (including customer operations as well as AWS services).
aws.databasemigration.network_receive_throughput bytes/second The amount of incoming network traffic on the replication instance (including customer operations as well as AWS services).
aws.databasemigration.full_load_throughput_bandwidth_target kilobytes/second The Outgoing data transmitted from a full load for the target in KB per second.
aws.databasemigration.full_load_throughput_rows_target count/second The Outgoing changes from a full load for the target in rows per second.
aws.databasemigration.cdc_incoming_changes count The number of change events waiting to be applied to the target.
aws.databasemigration.cdc_changes_memory_source count The number of rows waiting in a memory and waiting to be committed from the source. You can view this metric together with CDCChangesDiskSource.
aws.databasemigration.cdc_changes_memory_target count The number of rows waiting in a memory and waiting to be committed to the target. You can view this metric together with CDCChangesDiskTarget.
aws.databasemigration.cdc_changes_disk_source count The number of rows waiting on disk and waiting to be committed from the source. You can view this metric together with CDCChangesMemorySource.
aws.databasemigration.cdc_changes_disk_target count The number of rows waiting on disk and waiting to be committed to the target. You can view this metric together with CDCChangesMemoryTarget.
aws.databasemigration.cdc_throughput_bandwidth_source kilobytes/second The Incoming data received for the source.
aws.databasemigration.cdc_throughput_bandwidth_target kilobytes/second The Outgoing data transmitted for the target.
aws.databasemigration.cdc_throughput_rows_source count/second The Incoming task changes from the source in rows per second.
aws.databasemigration.cdc_throughput_rows_target count/second The Outgoing task changes for the target in rows per second.
aws.databasemigration.cdc_latency_source seconds The difference in the timestamp of the last event captured from the source endpoint to the timestamp now of the AWS DMS instance.
aws.databasemigration.cdc_latency_target seconds The difference in the oldest event timestamp waiting to commit and timestamp now of the target instance.
aws.databasemigration.cpu_utilization percent The percent of CPU used by a task across multiple cores.
aws.databasemigration.swap_usage bytes The amount of swap used by a task.
aws.databasemigration.memory_usage percent The percent of memory occupied by a task. (a.k.a. resident set size)
