Metrics that show the overall status for Hive service.
| Row | Metrics | Description |
|---|---|---|
| WAREHOUSE SIZE - AT A GLANCE | DB count at startup | Number of databases present at the last warehouse service startup time. |
| Table count at startup | Number of tables present at the last warehouse service startup time. | |
| Partition count at startup | Number of partitions present at the last warehouse service startup time. | |
| WAREHOUSE SIZE - REALTIME GROWTH | #tables created (ongoing) | Number of tables created since the last warehouse service startup. |
| #partitions created (ongoing) | Number of partitions created since the last warehouse service startup. | |
| MEMORY PRESSURE | HiveMetaStore Memory - Max | Heap memory usage by Hive MetaStores. If applicable, indicates max usage across multiple instances. |
| HiveServer2 Memory - Max | Heap memory usage by HiveServer2. If applicable, indicates max usage across multiple instances. | |
| HiveMetaStore Offheap Memory - Max | Non-heap memory usage by Hive MetaStores. If applicable, indicates max usage across multiple instances. | |
| HiveServer2 Offheap Memory - Max | Non-heap memory usage by HiveServer2. If applicable, indicates max across multiple instances. | |
| HiveMetaStore app stop times (due to GC stops) | Total time spent in application pauses caused by garbage collection across Hive MetaStores. | |
| HiveServer2 app stop times (due to GC stops) | Total time spent in application pauses caused by garbage collection across HiveServer2. | |
| METASTORE - CALL TIMES | API call times - Health Check roundtrip (get_all_databases) | Time taken to process a low-cost call made by health checks to all metastores. |
| API call times - Moderate size call (get_partitions_by_names) | Time taken to process a moderate-cost call made by queries/exports/etc to all metastores. Data for this metric may not be available in a less active warehouse. |
