ServiceWatch metric
Object Storage sends metrics to ServiceWatch. The metrics provided by basic monitoring are data collected at 5‑minute intervals. In Object Storage, you can view replication metrics by policy in ServiceWatch by enabling replication metrics for each bucket.
To enable ServiceWatch replication metrics, refer to How-to guides > Object Storage 복제 지표 활성화하기.
Basic Metrics
The following are the basic metrics for the Object Storage namespace.
Below, indicators whose names appear in bold are the key metrics selected from the basic metrics offered by Object Storage. Key metrics are used to configure service dashboards that are automatically built for each service in ServiceWatch.
Each metric provides guidance in the user guide on which statistical values are meaningful when viewing that metric, and among the meaningful statistics, the values shown in bold are the primary statistics. The service dashboard allows you to view key metrics using primary statistical values.

Replication metric
The following are replication metrics. Replication metrics are collected per replication policy. Replication metrics are collected only when the ServiceWatch replication metric is enabled for each bucket. The replication metrics are as follows.
| Performance items | Detailed description | unit | meaningful statistics |
|---|---|---|---|
| replication_total_count | Total number of objects to be transferred | Count |
|
| replication_transferred_count | Number of transmitted objects | Count |
|
| replication_progress_count | Number of objects being transferred | Count |
|
| replication_queued_count | Number of objects pending transmission | Count |
|
| replication_pending_count | Number of objects experiencing transmission delay | Count |
|
| replication_failure_count | Number of failed transmission objects | Count |
|
| replication_total_bytes | Total transfer target size | Bytes |
|
| replication_transferred_bytes | Transferred size | Bytes |
|
| replication_max_processing_time | Maximum processing time | Seconds |
|
| replication_avg_processing_time | Average processing time | Seconds |
