Monitoring Metrics using the HBase Write Test
The HBase Write Test can be launched on the Settings > Diagnostics > I/O Tests page.
HBase Write Test allows you to:
- Analyze the data being loaded, for example the number of unique metric/entity/tag combinations, and run a write throughput test.
- Launch an Auto Test to view a matrix of throughput statistics for different batch sizes and thread count combinations.
- Apply test results to modify the default configuration parameters in
series.batch.size = 1024 series.queue.pool.size = 4
Auto Test Example Results:
|Entity prefix||Entity name prefix.|
|Metric prefix||Metric name prefix.|
|Entities count||Number of unique entities to store.|
|Metrics count||Number of unique metrics to store.|
|Series count||Total number of series to store.|
|Tags count||Number of tags in each series. Set it to an estimated number of tags that are normally present in your series.|
|Batch size||Size of each test batch.|
|Thread count||Number of threads used for each test.|
|Start time||Start timestamp for the generated series.|
|Period, minutes||Period added to the Start Time timestamp with each iteration.|
|Log interval, seconds||Interval between log outputs.|
|Auto test delay, seconds||Delay between finishing one test and starting the next test in Auto Test mode.|
