Cluster Management services

Kyvos Manager allows you to manage the Kyvos cluster and services. Once you have deployed the cluster, you can also use these settings to update the cluster configuration.

This section provides an overview of the various configurations available on the Kyvos Manager. Please see the corresponding help page for further details.

To learn more about the actions that you can perform from the Kyvos Manager, see the Cluster actions section.

Manage cluster

This option on the navigation pane provides access to the Manage Cluster page that shows a cluster overview with details of all the nodes configured in the cluster.

You can use this page to:

  • Configure High Availability

  • Configure instances for BI Server, Web Portal, Postgres Server, and Standby Postgres Server

  • Add and delete nodes

For more information, click the Hadoop Ecosystem Configuration section for more details. 

Hadoop/EMR Ecosystem configurations

On this page, you can specify configurations for the ecosystem components in your Kyvos cluster, such as:

Query Engine YARN Configuration

This page is used  to  configure the YARN-based Query Engines specifying the number of cores and memory to be used in the cluster if you have deployed the cluster in YARN mode. 

  • You can also switch the cluster mode from YARN to non-YARN.

  • You can choose to add nodes to the cluster or configure existing nodes to assign the role of Query Engine to them.

Resources Configuration

This page is used to show the resources created at the time of cluster creation. You can add and remove resources/disks using the settings on this page.

Click here to know more.

Segmentation Configuration

This page is used to manage and create multiple segments and divide the system resources (such as Query Engines or disk space) among these segments.

Click here to know more.

Properties 

This page is used to view, edit, add, or delete the Kyvos application-level properties governing your cluster environment.

Configuration Files

This page is used to  update and upload the Configuration Files on the cluster.

  • Utilities options allowing you to monitor:

    • Audit Trail helps to track changes in configuration parameters.

    • Cluster Logs help to track changes made to the cluster.

    • Cluster Snapshot showing the entire cluster configuration settings in one place.

    • Events occurred on the cluster.

    • Reminders and email messages for alerts, warnings, services status, or nodes down

    • Operations performed on the cluster.

    • Agent Logging Configuration allows you to configure agent logging parameters like log level, file size, and backup file count.
