MRS Manager Introduction

Overview

The MRS manages and analyzes massive data and helps users rapidly obtain desired data from both structured and unstructured data. However, structures of open source components are complicated and component installation, configuration, and management are time-consuming and labor-intensive.

MRS Manager provides a unified enterprise-level platform for managing big data clusters. It provides the following functions:

  • Cluster monitoring

    Enables you to quickly know the health status of hosts and services.

  • Graphical indicator monitoring and customization

    Enables you to obtain key system information in time.

  • Service property configuration

    Meets your service performance requirements.

  • Cluster, service, and role instance operations

    Enables you to start or stop services and clusters with just one click.

MRS Manager Interface

MRS Manager provides a unified cluster management platform to help users rapidly run and maintain clusters.

Table 1 describes the functions of operation entries.

Table 1 Function description of MRS Manager operation entries

Operation Entry

Function Description

Dashboard

Shows the status and key monitoring indicators of all services, as well as the host status, in histograms, line charts, and tables. Users can customize a dashboard for the key monitoring indicators and drag it to any position on the interface. Data can be automatically updated on the dashboard.

Service

Provides service monitoring, operation guidance, and configuration, which help users manage services in a unified manner.

Host

Provides host monitoring and operation guidance to help users manage hosts in a unified manner.

Alarms

Provides alarm query and guidance to clear alarms, which enables users to quickly identify product faults and potential risks, ensuring proper system running.

Audit

Queries and exports audit logs to help users know all users' activities and operations.

Tenant

Provides a unified tenant management platform.

System

Enables users to manage monitoring and alarm configurations as well as backup.

On the page of a subfunction of System, you can use the System shortcut menu to go to another subfunction page.

  • Table 2 describes the System shortcut menu of a common cluster.
  • Table 3 describes the System shortcut menu of a security cluster.

The following describes how to use the System shortcut menu to go to a function page.

  1. On MRS Manager, click System.
  2. On the System page, click a link of any function to go to the function page.

    For example, in the Backup and Restoration area, click Back Up Data to go to the Back Up Data page.

  3. Move the cursor to the left boundary of the browser window. The black System shortcut menu is unfolded. After you move the cursor away, the shortcut menu will be folded.
  4. On the shortcut menu, click a function link to go to the function page.

    For example, choose Maintenance > Export Log. The Export Log page is displayed.

Reference Information

MRS is a data analysis service on the public cloud. It is used for management and analysis of massive data.

MRS uses the MRS Manager portal to manage big data components, for example, components in the Hadoop ecosystem. Table 4 details the differences between MRS on the public cloud and on the MRS Manager portal.
