Validations – Cloudera Support’s Predictive Alerting Program
Cloudera Support’s cluster validations proactively identify known problem signatures contained in customers’ diagnostic data with the goal of increasing cluster health, performance, and overall stability. Cluster validations are included in a customer’s enterprise subscription at no additional cost. All customers with access to the Support case portal will also be able to take advantage of cluster validations. In order to take advantage of validations customers need only provide the latest diagnostic bundle from their supported clusters.
Cluster diagnostic data (obtained from diagnostic bundles) can be sent to Cloudera Support directly from the product (CDP Private Cloud Base or legacy CDH/CM), as an attachment in a support case, or manually through a phone_home script available on cloudera.com.
Cloudera’s arsenal of problem signatures relates to misconfigurations, security vulnerabilities, performance degradation, deviations from our known best practices, as well as many other types of commonly experienced issues that can result in general cluster instability.
Validation alerts are designated a severity level, including critical, error, warning, information, and curiosity based on the impact to the cluster. Included with the alert are the relevant problem details, affected hosts in the cluster, as well as applicable documentation.
The following screenshot taken from MyCloudera illustrates the format in which validation alerts are displayed to customers. Expanding each row allows access to the specific alert details pertaining to each alert category.
In March 2021, Cloudera Support announced on-demand self-service access for customers to their entire suite of cluster validations directly in the MyCloudera customer portal. Previously delivered to customers via a push model, validations in MyCloudera now enable customers to more conveniently self-solve common cluster misconfigurations before they manifest into larger and more impactful problems.
We’ve put together this short video introducing validations in MyCloudera, which includes a demo for you to see the tool in action.
New validations functionality in MyCloudera includes:
- Clear designation and identification of newly uncovered cluster alerts
- The ability to mark specific validation alerts as “reviewed” to classify those that have been resolved
- The capability of silencing an entire cluster’s notifications if the environment is designated as a sandbox, for example
- Self-service control over who is designated as a “validation alert recipient” on the account in question (controls email notifications)
Cloudera Support recommends that customers review their validation alerts contained in MyCloudera under Assets and perform the recommended corrective actions.
If planning or consultative assistance is required, customers can contact their sales account team for advice and recommendations. For technical assistance with a break/fix support matter relating to the validation, a case can be filed using the instructions here.
