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 for each replication policy in ServiceWatch by enabling replication metrics per bucket.
Refer to How-to guides > Object Storage 복제 지표 활성화하기 for how to enable ServiceWatch replication metrics.
Basic Metrics
The following are basic metrics for the Object Storage namespace.
The indicators whose names are displayed in bold below are the indicators selected as key among the basic metrics provided by Object Storage. The key metrics are used to build service dashboards that are automatically created for each service in ServiceWatch.
Each metric provides guidance in the user guide on which statistical values are meaningful when querying that metric, and among the meaningful statistics, the values displayed in bold are the primary statistics. In the service dashboard, you can view key metrics through primary statistical values.

Replication metric
The following are replication metrics. Replication metrics are collected per replication policy. Replication metrics are collected only when ServiceWatch replication metrics are 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 objects transmitted | 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 with transmission delay | Count |
|
| replication_failure_count | Number of failed transmission objects | Count |
|
| replication_total_bytes | Total transmission target size | Bytes |
|
| replication_transferred_bytes | Transferred data size | Bytes |
|
| replication_max_processing_time | Maximum processing time | Seconds |
|
| replication_avg_processing_time | Average processing time | Seconds |
