Usage
The Usage page shows how a project consumes connections, messages, channels, and bandwidth over a time range. Use it to compare traffic against your plan limits.
Open a project in QPub Cloud, then select the Usage tab.
Choose a time range
Use the clock control in the page header.
Quick ranges include Last 5 minutes through Last 5 years (for example Last 1 hour, Last 24 hours, Last 7 days). The default is Last 1 hour.
You can also pick a custom start and end date in the calendar, then Apply. Future dates are disabled.
The header button shows the active quick-range name, or a formatted start–end range for custom selections.
Charts
Six live charts (history for the selected range):
| Chart | Series |
|---|---|
| Connections | Peak Connections, Average Connections, Total Connection Time |
| Messages | Published Messages, Delivered Messages, Total Messages |
| Channels | Peak Channels, Average Channels, Total Channel Time |
| Subscribers | Peak Subscribers, Average Subscribers |
| Message Size | Total Message Size, Average Message Size |
| Bandwidth | Total Bandwidth, Average Bandwidth |
Charts support horizontal zoom along the time axis.
Summary table
Below the charts, Summary lists aggregated metrics for a date window shown in the card subtitle.
Columns: Metric | Usage.
Rows include peak/average connections and channels, connection and channel time (minutes), peak/average subscribers, messages published/delivered/total, message size totals/averages, and bandwidth totals/averages.
When you use a quick range, the summary window matches the charts. For a custom range, confirm the Summary subtitle if it differs from the header picker.
If data fails to load
The page may show Unable to load usage data. Refresh the page or pick a different time range.
