Visualize HDFS Performance Metrics
The HDFS Canary Dashboard displays key metrics that help monitor the health and responsiveness of HDFS operations. You can track file creation throughput, read/write latency, operation size, directory listing duration, and delete time.
HDFS Canary Dashboard Charts
These charts help identify performance degradation and ensure consistent data transfer rates across the cluster.
| Chart | Description |
|---|---|
| HDFS Canary File Creation Throughput | Displays the data transfer rate during file creation, indicating overall write performance. |
| HDFS Canary File Read Time | Measures the time taken to read a file, helping assess read latency. |
| HDFS Canary File Ops Size | Shows the size of the file used in the canary test, useful for correlating performance with file size. |
| HDFS Canary Read Write Status | Indicates the success or failure of HDFS read and write operations. |
| HDFS Canary List Dir Duration | Displays the latency for listing directory contents in HDFS. |
| HDFS Canary File Delete Time | Measures the time required to delete a file, reflecting HDFS delete operation performance. |
| HDFS Canary Local File Creation Time | Shows the time taken to create a local file before uploading it to HDFS. |
| HDFS Canary List Dir Status | Indicates the success or failure status of directory listing operations. |
