For cPanel & WHM 11.46

(Home >> Logs >> Bandwidth)


The Bandwidth interface displays bandwidth usage information in several sets of graphs. Each graph contains information about bandwidth usage over a specific period of time.

The graphs display bandwidth information in six categories:

  • Http (web traffic)
  • Pop3 (received email)
  • Imap (received email)
  • Ftp (file transfer)
  • Smtp (sent email)
  • All


  • The All category displays in green and provides the combined total of all of the other categories.
  • The system only records bandwidth for outgoing SMTP messages. The system does not include incoming messages in bandwidth calculation.

This information allows you to monitor the heaviest traffic times for your website, and helps you decide whether to purchase additional bandwidth.

The bar graphs

The Today graph

The Today graph shows the data transfer rate in bits per second for the current day, averaged into five minute intervals.

A sample Traffic for Today graph.

By default, this graph updates every two hours. However, if your hosting provider adjusts the bandwidth data process interval in WHM's Statistics Software Configuration interface (Home >> Server Configuration >> Statistics Software Configuration) the amount of bandwidth data that the system displays is affected.

Use this graph to view the following information:

  • Small-scale trends, for example, quick spikes in traffic at specific times.
  • Changes over the course of the day, for example, increases and decreases in traffic.

The Past 7 Days graph

The Past 7 Days graph shows the data transfer rate, in bits per second, over the past seven days, averaged into five-minute intervals.

A sample Past 7 Days graph.

Use this graph to view the following information:

  • Larger-scale trends; for example, for example, spikes in traffic at the same time each day for the past three days.
  • Changes from the past week, for example, increases or decreases in traffic over a period of two to seven days.


The Past 12 Months graph

The Past 12 Months graph shows the total amount of data that the system transferred over a period of 12 months.

A sample Past 12 Months graph.


Use this graph to find long-term trends over an entire year. For example, your account receives a heavy burst of traffic at mid-month every month.

Monthly pie charts

The monthly pie charts allow you to visually compare the relative amounts of data that your cPanel account's various services and domains run.

A sample pie chart.

Use the pie charts to view the following information:

  • The total amount of data that the system transferred for the month.
  • When there is a noticeable change in the relationships between services from month to month.
    • For example, SMTP total bandwidth increased from 5% to 50% in one month, while HTTP bandwidth decreased.
  • When there is a change in the bandwidth usage of one domain relative to another.
    • For example, The domain accounts for about half of the overall traffic of all sites, and accounts for about 25%.

To view the Bandwidth Transfer Detail interface for that month, click a pie chart.


Click the appropriate usage link next to the monthly pie chart to look up usage information for an individual website or service. The system will take you to a new interface which displays detailed monthly traffic information for that particular service and website.

The Bandwidth Transfer Detail interface

To view the bandwidth transfer information for a particular month, click Total (all services).

This interface contains a series of bandwidth usage graphs that pertain to a particular month for the following types of traffic:

  • HTTP
  • SMTP
  • FTP
  • POP3
  • IMAP

The Bandwidth By Day table

The Bandwidth by Day table lists the total amount of the cPanel user account's data that the system transferred on a specific day of the month, in megabytes.

Click a day in the table to view more information about that day's traffic.

A sample Bandwidth by Day table.


We recommend that you view the Bandwidth by Day table at least 24-48 hours after the last day of the period for which you wish to obtain data. This allows the system to gather and process the traffic data.

The All Traffic monthly graph

The All Traffic monthly graph shows the hourly average bytes that the system transferred for the month that you select. It provides a more detailed version of the data than the Past 12 Months graph.

A sample All Traffic monthly graph.

Use this graph to find trends over a period of several days or weeks. For example, whether traffic is heavier at certain times of day, or on certain days of the week.

Monthly traffic graphs by service

The monthly traffic graphs serve the same purpose as the All Traffic graph, but the system separates the data to make it easier to recognize trends for a service.

A sample Http Traffic monthly graph.


All Traffic daily graph

The All Traffic daily graph shows 30-minute averages of bits transferred per second. It is a more detailed version of the All Traffic monthly graph from the Bandwidth Transfer Detail interface.


A sample All Traffic daily graph.

Daily traffic graphs by service

Under the All Traffic graph is a series of one or more bar graphs for specific services. These serve the same purpose as the All Traffic graph, but the system separates the data to make it easier to recognize a single service's trends.
