Hive Health Tests

This is a Hive service-level health test that checks that enough of the Hive Metastore Servers in the cluster are healthy. The test returns "Concerning" health if the number of healthy Hive Metastore Servers falls below a warning threshold, expressed as a percentage of the total number of Hive Metastore Servers. The test returns "Bad" health if the number of healthy and "Concerning" Hive Metastore Servers falls below a critical threshold, expressed as a percentage of the total number of Hive Metastore Servers. For example, if this test is configured with a warning threshold of 95% and a critical threshold of 90% for a cluster of 100 Hive Metastore Servers, this test would return "Good" health if 95 or more Hive Metastore Servers have good health. This test would return "Concerning" health if at least 90 Hive Metastore Servers have either "Good" or "Concerning" health. If more than 10 Hive Metastore Servers have bad health, this test would return "Bad" health. A failure of this health test indicates unhealthy Hive Metastore Servers. Check the status of the individual Hive Metastore Servers for more information. This test can be configured using the Hive Hive service-wide monitoring setting.

Short Name: Hive Metastore Server Health

Description
The health test thresholds of the overall Hive Metastore Server health. The check returns "Concerning" health if the percentage of "Healthy" Hive Metastore Servers falls below the warning threshold. The check is unhealthy if the total percentage of "Healthy" and "Concerning" Hive Metastore Servers falls below the critical threshold.

This is a Hive service-level health test that checks that enough of the WebHCat Servers in the cluster are healthy. The test returns "Concerning" health if the number of healthy WebHCat Servers falls below a warning threshold, expressed as a percentage of the total number of WebHCat Servers. The test returns "Bad" health if the number of healthy and "Concerning" WebHCat Servers falls below a critical threshold, expressed as a percentage of the total number of WebHCat Servers. For example, if this test is configured with a warning threshold of 95% and a critical threshold of 90% for a cluster of 100 WebHCat Servers, this test would return "Good" health if 95 or more WebHCat Servers have good health. This test would return "Concerning" health if at least 90 WebHCat Servers have either "Good" or "Concerning" health. If more than 10 WebHCat Servers have bad health, this test would return "Bad" health. A failure of this health test indicates unhealthy WebHCat Servers.

Short Name: WebHCat Server Health

Description

This is a Hive service-level health test that checks that enough of the HiveServer2s in the cluster are healthy. The test returns "Concerning" health if the number of healthy HiveServer2s falls below a warning threshold, expressed as a percentage of the total number of HiveServer2s. The test returns "Bad" health if the number of healthy and "Concerning" HiveServer2s falls below a critical threshold, expressed as a percentage of the total number of HiveServer2s. For example, if this test is configured with a warning threshold of 95% and a critical threshold of 90% for a cluster of 100 HiveServer2s, this test would return "Good" health if 95 or more HiveServer2s have good health. This test would return "Concerning" health if at least 90 HiveServer2s have either "Good" or "Concerning" health. If more than 10 HiveServer2s have bad health, this test would return "Bad" health. A failure of this health test indicates unhealthy HiveServer2s. Check the status of the individual HiveServer2s for more information. This test can be configured using the Hive Hive service-wide monitoring setting.

Short Name: HiveServer2 Health

Description
The health test thresholds of the overall HiveServer2 health. The check returns "Concerning" health if the percentage of "Healthy" HiveServer2s falls below the warning threshold. The check is unhealthy if the total percentage of "Healthy" and "Concerning" HiveServer2s falls below the critical threshold.
