Qumulo Core Dashboard


Provides an overview of the Dashboard in Qumulo Core


  • Cluster running Qumulo Core 3.0.2 and above

NOTE: This article reflects the new Web UI for the Qumulo Core Dashboard available as of the 3.0.2 release. Since we gradually update the Web UI over time, some of these exciting widgets and analytics may be available in earlier versions of Qumulo Core. To get the full scope of this enhanced UI experience, ensure your cluster is running the latest version of Qumulo Core.


Qumulo Core's Dashboard provides an overview of important cluster analytics and data so that you can easily get the answers you need about your storage. Once you login to the Web UI, you'll land on the Dashboard page and be able to review general details about your cluster, capacity info, throughput activity, client connections, and more. The analytics provided in each Dashboard section outlined below are refreshed every five seconds so that you have the data you need in real time.


Cluster Overview

The Cluster Overview section provides a complete picture of your cluster’s overall health at a glance. Here's the breakdown of what you'll find:

Cluster Usage: Provides a color-coded pie chart and metrics on the consumption and availability of your storage—dark blue for Data, light blue for Metadata, green for Snapshots, and white for Available free space.

Number of Nodes: Displays the number of active nodes in your cluster.

Protection Status: Indicates drive failure protection status. 

File and Directory Count: Highlights the total file and directory count and displays the current increasing or decreasing change rate.


Cluster Activity

In this section, you'll find even more visual representations that outline the activity on your cluster. Navigate here to find the read and write metrics for the IOPS, Throughput, and Latency on your cluster. Hover anywhere over the graphs to see point-in-time values of each metric reflected on the right-hand side. You can use the sliding "scrubber" at the bottom to view a specific segment of time—drag either end of it to adjust the total time, or drag the scrubber itself (or click a specific region) to view any block in the last 24 hours.


Below the Throughput, IOPS, and Latency graphs, you'll find two additional widgets that outline the Throughput Distribution in bar graph form over the last 24 hours. To quickly determine your read and write throughput rate in real time, use the dashed, white "Current" line.


Client Activity

The Client Activity section allows you to easily determine the whos, wheres, and whens of the client connections on your cluster. Here you'll find the following details:

Client Connect Distribution: Provides a deep dive of the connections across your cluster displaying the NFS, SMB, and the total number of connections per node in both numerical and bar graph form. If you have 9 nodes or fewer, a bar for each node in your cluster will be available. For clusters featuring more than 9 nodes, the 4 nodes with the highest number of connections and the 4 nodes with the lowest number of connections will be displayed.

Most Active Clients: Highlights the busiest clients according to throughput and IOPS and includes details for reads, writes, and the IP address of the client in the Client Activity section.


Capacity Trends

Capacity Trends gives you the details you need to monitor and manage your cluster’s capacity usage over time. Here you can quickly see significant changes by capacity in your data, verify when users are writing significant amounts of data, and track large deletes in the form of negative capacity changes. In this section you'll find the following:

Summary of Changes: Highlights capacity changes over the the last 72 hours for metadata, data, and snapshots.

Top Directory Changes: Outlines which directories (up to 4) on your cluster have had the biggest change (increase or decrease) over the last 72 hours. 



You should now understand the analytics provided in the Dashboard of Qumulo Core
