Manage the system using the Weka GUI

Weka GUI application enables you to configure, administer, and monitor the Weka system. This page provides an overview of the primary operations, access to the GUI, and system dashboard.

Weka GUI overview

Weka GUI application is the administration tool for your Weka system. Use this tool for system configuration, filesystems management, user management, and investigation of alarms, events, and statistics.
Weka GUI application supports the following functions:
  • Configuration:
    • Configure the cluster, such as data availability, license, security, and central monitoring.
    • Configure the backend servers and expose the data in different protocols.
    • Manage local users and set up the user directory.
    • Create and manage organizations and their quotas.
  • Management:
    • Manage the filesystems, including tiering, thin provisioning, and encryption.
    • Manage snapshots.
    • Manage the object store buckets.
    • Manage the filesystem protocols: SMB, S3, and NFS.
  • Investigation:
    • Investigate events
    • Investigate overtime statistics, such as total operations, R/W throughput, CPU usage, and read or write latency.
  • Monitoring:
    • View the cluster protection and availability.
    • View the R/W throughput
    • View the backend and client top consumers.
    • View alarms.
    • View the used, provisioned, and total capacity.
    • View the frontend, compute, and drive cores usage.
    • View the hardware components (active/total).
Weka GUI overview

Access the Weka GUI

Weka GUI is a web application that you can access using an already configured account and has the appropriate rights to configure, administer, or view.
You can access the Weka GUI with any standard browser using the address: https://<weka system or host name>:14000
For example: https://WekaProd:14000 or https://weka01:14000.
On AWS installations, you can access the Weka GUI from the self-service portal. In the Outputs tab of the CloudFormation stack, click the GUI link.
Before you begin
Make sure that port 14000 is open in the firewall of your organization.
Procedure
  1. 1.
    In your browser, go to https://<weka system or host name>:14000. The sign-in page opens.
Sign in to Weka GUI
2. Sign in with the username and password of an account with cluster administration or organization administration privileges. For details about the account types, see User management in the related topics.
The system dashboard opens.
The initial default username and password are admin and admin. In the first sign-in, Weka GUI enforces changing the admin password.

System Dashboard

The system dashboard contains widgets that provide an overview of the Weka system, including an overall status, R/W throughput, top consumers, alerts, capacity, core usage, and hardware.
The system dashboard opens by default when you sign in. If you select another menu and you want to display the dashboard again, select Monitor > System Dashboard, or click the WEKA logo.
System Dashboard

Cluster Protection and Availability widget

This widget shows the overall status of the system's health and protection.
The overall status widget includes the following indications:
  • Service Uptime: The elapsed time since the I/O services started.
  • Data Protection: The number of data drives and protection parity drives. The color of the protection parity drives indicates their status.
  • Virtual (Hot) Spares: The number of failure domains that the system can lose and still complete the data rebuild while maintaining the same net capacity.
Overall status widget

R/W Throughput widget

This widget shows the current performance statistics aggregated across the cluster.
The R/W Throughput widget includes the following indications:
  • Throughput: The total throughput.
  • Total Ops: The number of cluster operations.
  • Latency: The average latency of R/W operations.
  • Active clients: The number of clients connected to the cluster.
R/W Throughput widget
Selecting the titles R/W Throughput, Latency, and Total Ops displays the statistics page.
Selecting the title Active clients displays the client machines page.

Top Consumers widget

This widget shows the top 5 backend and client hosts in the system. You can sort the list of hosts by total IO operations per second or by total throughput.
Top Consumers widget

Alerts widget

This widget shows the alerts that are not muted.
Alerts widget

Capacity widget

This widget shows an overview of the managed capacity.
The top bar indicates the total capacity provisioned for all filesystems and the used capacity. For tiered filesystems, the total capacity also includes the Object Store part.
The bottom bar indicates the total SSD capacity available in the system, the provisioned capacity, and the used capacity.
Capacity widget
Selecting the title Capacity displays the filesystems page.

Core Usage widget

This widget shows the average usage and the maximum load level of the Frontend, Compute, and Drive cores.
Core Usage widget

Hardware widget

This widget shows an overview of the hardware components (active/total).
The hardware components include:
  • Backends: The number of servers.
  • Cores: The number of cores configured for running processes in the backends.
  • Drives: The number of drives.
  • OBS Buckets: The number of the object-store buckets.
Hardware widget
Selecting the titles Backends, Cores and Drives displays the backend machines page.
Selecting the title OBS buckets displays the object store buckets page.

Switch the display time

Timestamps in events and statistics are logged internally in UTC. Weka GUI displays the timestamps in local or system time. You can switch between the local and system time.
Switching the display time may be required when the customer, Weka support, and the Weka system are in different time zones. In this situation, the customer and Weka support can switch the display to system time instead of local time, so both view the identical timestamps.
Procedure
  1. 1.
    On the top bar, point to the timestamp.
  2. 2.
    Depending on the displayed time, select Switch to System Time or Switch to Local Time.
Switch display time

Switch the GUI between light and dark modes

You can switch the GUI between light and dark modes according to your preferences. The dark mode is a user interface for content that displays light text on a dark background. The dark mode is beneficial for viewing screens at night. The reduced brightness can reduce eye strain in low light conditions.
Procedure
  1. 1.
    On the top bar, depending on the current display mode, point to the sun or moon symbol.
  2. 2.
    Select Switch to light mode or Switch to dark mode.
Switch the GUI between light and dark modes

Display tables

When managing filesystems, snapshots, and object stores the displayed tables listing the rows have two behaviors in common.
  • The table title specifies also the number of rows in the table and the maximum number of rows that the table can display.
  • You can customize the columns displayed on the table using the column selector.
Example: Display the filesystems table
