Metric definition
Updated at：2025-11-11
Currently, the file system supports monitoring and alerting for the following metrics:
| Metric categories | Metric name (English) | Metric name (Chinese) | Unit | Description |
|---|---|---|---|---|
| Read statistics | ReadThroughputNew | Read throughput | Bytes per second | Read throughput of the file system within a cycle |
| ReadLatencyNew | Read latency | ms | Average read latency of the file system within a cycle | |
| ReadIONew | Read IOPS | Time/second | Number of read I/Os of the file system within a cycle | |
| ReadIOErrorCount | Read io error | Times/minute | Number of read I/O errors of the file system within a cycle | |
| Write statistics | WriteThroughputNew | Write throughput | Bytes per second | Write throughput of the file system within a cycle |
| WriteLatencyNew | Write latency | ms | Average write latency of the file system within a cycle | |
| WriteIONew | Write IOPS | Time/second | Number of write I/Os of the file system within a cycle | |
| WriteIOErrorCount | Write io error | Times/minute | Number of write I/O errors of the file system within a cycle | |
| Metadata statistics | MetaReadQpsNew | Metadata Read QPS | Time/second | Average number of metadata read I/Os of the file system within a cycle |
| MetaWriteQpsNew | Metadata Write Qps | Time/second | Average number of metadata write I/Os of the file system within a cycle | |
| MetaReadErrorCount | Metadata read io error | Times/minute | Number of metadata read I/O errors of the file system within a cycle | |
| MetaWriteErrorCount | Metadata write io error | Times/minute | Number of metadata write I/O errors of the file system within a cycle | |
| Mount/unmount exception statistics | MountErrorCount | Number of mount failures | Times/minute | The number of mount errors for the file system during a cycle (only counting cases where the server received the request but failed to process it successfully). If no data appears in the monitoring chart, it means there were no mount failures. |
| UmountErrorCount | Number of unmount failures | Times/minute | The number of unmount errors for the file system during a cycle (only counting cases where the server received the request but failed to process it successfully). If no data appears in the monitoring chart, it means there were no unmount failures. | |
| Usage statistics | Capacity | Storage usage | Byte | Current used capacity of the file system (excluding backup data) |
| FileNum | Number of files | Item | Number of files in the file system within a cycle (excluding directories) | |
| UsagePercentage | Storage utilization | % | If the upper limit of file system capacity is set up, the capacity utilization = used capacity/ upper limit of capacity; if not, the capacity utilization =0 |
