OpenText Analytics Database 26.2.x – Getting started with MC

Mc: Connecting to MC

Mon, 01 Jan 0001 00:00:00 +0000

To connect to Management Console:

Open a supported web browser.
Enter the IP address or host name of the host on which you installed MC (or any cluster node if you installed OpenText™ Analytics Database first), followed by the MC port you assigned when you configured MC. For example:

Enter the IP address and port:
```
https://10.20.30.40:5450/
```
Enter the host name and port:
```
https://hostname:5450/
```
When the MC logon dialog appears, enter your MC username and password and click Log in.

Note
When MC users log in to the MC interface, MC checks their privileges on the database Data collector (DC) tables on MC-monitored databases. Based on DC table privileges, along with the role assigned the MC user, each user's access to the MC's Overview, Activity and Node details pages could be limited. See Users, roles, and privileges in MC for more information.

If you do not have an MC username/password, contact your MC administrator.

Managing client connections

Each client session to MC uses a connection from MaxClientSessions, a database configuration parameter. This parameter determines the maximum number of sessions that can run on a single database cluster node. Sometimes multiple MC users, mapped to the same database account, are concurrently monitoring the Overview and Activity pages.

Tip

You can increase the value for MaxClientSessions on an MC-monitored database to account for extra sessions. See Managing sessions for details.

Mc: Management Console toolbar and navigation

Mon, 01 Jan 0001 00:00:00 +0000

Mc: Management Console home page

Mon, 01 Jan 0001 00:00:00 +0000

After you log in to the MC, the Databases page displays. Your assigned roles and privileges determine what information you can view and which areas you can access.

The following image is an example of what the MC SUPER administrator views after login:

Databases overview

The Databases page displays a dynamic dashboard that describes the health and important statistics for all databases that the MC manages. If you have not yet created or imported a database with the MC, this page lists no databases.

Dashboard refresh

The MC provides dashboard refresh options so you can view the most recent information about your databases:

The refresh section consists of the following:

Timestamp that displays the date and time of the most recent dashboard refresh.
Manual refresh icon that refreshes the dashboard as needed.
Auto Refresh feature, which is available from the down arrow to the right of the manual refresh icon. You can select the down arrow, then select the Auto Refresh box so that the MC refreshes the dashboard every two minutes.

Database actions

You can perform database actions with the dropdown directly below the refresh options. The following image shows the expanded dropdown:

The Create new database option is always displayed. The dropdown lists the following database actions:

Revive Eon Mode database. For details, see the revive documentation for your cloud provider.
Import database.

Note

Your environment determines the options available in the dropdown. For example, if you deploy only an Enterprise database, the Revive Eon Mode database option is not in the list.

Database views

The MC provides information about your databases in detailed or condensed views. To select the view, use the icons to the right of the database actions dropdown:

The left button displays the Condensed view, and the right button displays the Detailed view. Both views provide the following features:

If the database contains multiple subclusters, the subclusters are grouped together in a single tile. Within that database tile, there is a row that displays information for each subcluster. The default subcluster is displayed in the top row of each database tile.
You can select the database name in the top-left of the database tile and go to its Overview page.
The IP dropdown lists the IP addresses of each node in the database. Select an IP address from the list to monitor the node activity.
The vertical ellipses in the top-right of each database tile provides the following options:
- Manage Database to go to the Manage page to view your subcluster layout.
- Execute Query to go the Query Execution page.

Detailed view

By default, the MC displays database information in the detailed view. The following image shows two databases, and the first database has two subclusters:

Each subcluster row contains four tiles that display the following information:

Node State: Graphic representation of the node state for the cluster. This tile displays how many nodes are in the UP state and when the database was last started or stopped. Select this tile to go to the database's Manage page to view the subcluster layout.

Each circle represents a database node, and its color represents its state:
- Green: Node is healthy and UP.
- Yellow: Critical state and needs attention.
- Red: Node is DOWN.
- Gray: Cluster is stopped, and the node is DOWN.
Queries: Query success rate for the past hour.

Select this tile to go to the Query Monitoring page.
CPU & Memory (Hourly): Database CPU and memory usage for the past hour.

Select this tile to go to the Overview page.
Projections: Details about the database projections. Select the down arrow to view the projections for a specific schema.

Select this tile to go to the Table Utilization page in the Activity section.

If there are multiple subclusters in a database, you can toggle the arrow in the top-right of the subcluster row to collapse or expand the subcluster row.

Condensed view

The condensed view displays minimal information about each database and its subclusters. If you have multiple databases, this view lets you view more information on the screen simultaneously. The following image shows two databases, and the first database has two subclusters:

To view a description of the current status of your database, hover your cursor over the subcluster name.

Each subcluster row contains buttons that display important cluster information. You can select one fo the following buttons to go to the Overview page and view detailed information about the cluster:

CPU Usage
Memory Usage
Disk IO Usage

Below the buttons, there is a graphic representation of the node state for the subcluster and a timestamp that describes when the subcluster last started or stopped.

Mc: Creating a cluster using MC

Mon, 01 Jan 0001 00:00:00 +0000

Enterprise Mode only

After you install and configure MC, you can use Management Console to install a database cluster on hosts where OpenText™ Analytics Database has not been installed. The Cluster Installation assistant lets you specify the hosts you want to include in your database cluster, loads the database onto the hosts, validates the hosts, and assembles the nodes into a cluster.

Complete the following tasks:

Prepare the hosts - Prepare each host that will become a node in the cluster.
Create a private key file - MC needs password-less SSH to connect to hosts and install the database. Create a private key to enable MC access to the hosts.
Use the MC cluster installation wizard - Use the wizard to install a database cluster on hosts that do not have the database already installed on them.
Validate hosts and create the cluster - Host validation is the process where the MC runs tests against each host in a proposed cluster. You must validate hosts before the MC can install the database on each host.

After you successfully create a cluster using MC, see Create a database on a cluster.

Mc: Monitoring existing infrastructure using MC

Mon, 01 Jan 0001 00:00:00 +0000

Use Management Console to monitor the health of your databases and clusters. Click the Infrastructure button on the Home page to see the Databases and Clusters page. Then click the cluster of interest to view the health of the nodes in that cluster and the key information associated with the cluster such as:

OpenText™ Analytics Database version
Number of hosts
CPU type
Last updated date
Node list.

You can also zoom in and out for better view of this page.

On the Databases and Clusters page or the Home page, click the database which you want to monitor, to go to its Overview page:

You can perform the following tasks from the Overview page:

View Quick Stats to get instant alerts and information about your cluster's status.
View Status Summary that provides a general overview of the status of your cluster (as shown in preceding figure).
Analyze System Health using a comprehensive summary of your system resource usage and node information, with configurable statistics that allow you to specify acceptable ranges of resource usage.
Use Query Synopsis to monitor system query activity and resource pool usage.

For Eon mode databases, the Status Summary and Query Synopsis pages allow you to display information for the entire database. If subclusters are defined, you can also display information for a specific subcluster or node, or the nodes not assigned to a subcluster.

Additionally, you can perform the following tasks from the Overview page:

Monitoring system resources

On the main window, you can click the database, and navigate to the MC Activity tab to monitor system resources such as:

Monitoring node and MC user activity

You can use the MC Manage page to monitor node activity. When you click the node you want to investigate, the Node Detail page opens and provides:

Summary information for the node
Resources consumed by the node for last three hours

You can also browse and export log-level data from AgentTools and database log files. MC retains a maximum of 2000 log records. See Monitoring node activity with MC for further details.

Use MC Diagnostics tab and navigate to Audit Log page to manage MC User activity. See Monitoring MC user activity using audit log.

Monitoring messages in databases managed by MC

You can view critical database related messages from MC Message Center. The MC Message Center reports on several critical database-related conditions using a color code to indicate the message severity. For further details, see Monitoring database messages and alerts with MC.

You can also search and sort database messages, mark messages read or unread and delete them. You can filter messages by message type, and export messages. For additional information, refer to Message center and Exporting MC-managed database messages and logs.

Monitoring and configuring resource pools

Use the MC Activity page to monitor resource pools. Select the resource pool you want to monitor. MC displays the following charts for the selected pool:

Resource Usages in Pool
Memory Usage in Node and Subclusters
Average Query Execution and Query Time in Pool
Resource Rejections in Pool

If you are a database administrator, you can click the database you want on the main window. You can then use the MC Settings tab to view and edit the resource pool parameters. Only the database administrator can monitor and configure the resource pools in Management Console.

See Monitoring resource pools with MC for further information.
