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.

See the Cluster details section to know more about the details shown on the Kyvos Manager Dashboard. 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.

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.

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.

Instances State Configuration

Use these settings to activate or deactivate the BI Server and Query Engine instances in your cluster.

Uploading External Libraries

This page is used to upload any third-party JAR files that you want to use for the Kyvos environment.

Disaster Recovery

This page is used to restore the system from a disaster. You can also manually recover Kyvos Manager nodes and roles on it. Both guided, and manual recovery are supported.

Cluster Monitoring services

Kyvos Manager allows you to monitor the cluster state through multiple options available on the navigation pane.

You can see:

The dashboard with the state of all Kyvos clusters and nodes. The dashboard also shows a graphical representation of the node-level utilization metrics.
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.
