Common UI features

Here are some explanations for some common features seen throughout various screens within the DBmarlin user interface.

Header Section


The breadcrumbs allows you to navigate back to the previous screens as you drill down. You can also use the 'Back button' on your browser.

Date selector

The date selector allows you to choose either relative or absolute dates and times. Once selected the same time range is maintained as you navigate from one screen to the next.


Custom Interval

The date selector also has the option to set a "Custom Interval" to change the granularity of the charts. The default is "Auto" which will attempt to display a sensible number of data points per chart taking into account the performance and legibility of the charts.

For example, with a 1 hour period, Auto will return 60x 1-minute data points but using the custom interval, you could override this and ask for the data in 15-second intervals. The custom interval is remembered until you make changes within the date selector after which it will revert to "Auto".

Note that selecting an interval smaller than the frequency at which the data is collected could cause strange results. For example setting a 1 second interval for statistics which are only collected every minute.

Choose Snapshot

Select a saved snapshot to apply. A snapshot is a named time range (and optionally additional filters) that had been previously saved.

Save Snapshot

Save the current time range and any filters applied as a snapshot so you can easily reapply the same filters again in the future. Clicking the Save Snapshot button will prompt for a Name, Description and a toggle option which allows you to "Keep Data". If you enable "Keep Data" then the data will not be purged after the normal data retention period for per second and per hour data.

Saved snapshot

There are many use cases for saved Snapshots including:

  1. Save a snapshot for an incident - so it can be linked to the Incident record for future reference
  2. Save a snapshot for a peak trading period such as Black Friday
  3. Save a snapshot for a load test - so that it can be compared to a different load test
  4. Save a snapshot for any period of time you need to keep a high granularity beyond the retention period.

Saved snapshots can be recalled from the Choose Snapshot dropdown or used for period selection in the Time Comparison Report

Saved snapshots can be deleted once they are no longer needed from the Snapshot Settings screen.

The copy link button allows you to copy a deep link URL to the current screen and time selection so that it can be shared with others. For example you could email, instant message or attach the URL in a support ticket and others clicking on the link will get to exactly the same view as you.

If you have a relative time period such as Last hour selected then the copied link will be a fixed time period of 1 hour from the time at which the button was clicked. This means the data could differ slightly from the screen you are looking at if there is a delay between refreshing the screen data and clicking the Copy link button.

Content Section

Collapsing widget panels

For any widget panel which has a minus sign in the top right hand corner it is possible to collapse the panel or expand it by clicking anywhere in the widget header. This is useful if you want to minimise certain widgets for example.


Zoom on charts

You can drag your mouse around a part of the chart to zoom in on that part. To get back to the orginal time range click the 'Reset zoom' button in top right of the chart.


Search within table data

The Search box lets you search within the table data including all visible field and also some hidden field such as Database Type which might not be visible in the table. To clear the search you can either delete the text from the Search box or click the Clear button.

Table Exporting data

The Export button at the top of the table allows exporting of table data to CSV format which can then be opened in Excel.

Table pagination

The tables by default show the top 10 records. You can use the dropdown below the table to show 20, 30 or all rows.

Table limits

The tables by default show only the top 500 records for performance reasons. If you hit the limit a banner will show warning that the number of rows is greater than 500.
