Performance Considerations

It took 10 minutes for a log to render a change from 3,500 to 12,100 log lines where the the new 8,600 lines where produced within a 1 minute burst. Another log was also active throughout this 10 minute period which had around 800 before the burst and 1,300 after the app finished rendering the burst.

Render time between log output page changes remained under/around 1 to 2 seconds.

Another browser was watching the slower log throughout this test and its performance was unaffected.

To Do

Essential Improvements

Removal of console output on client-side code or a Log Level management tool.

COMPONENTDIDUPDATE tracker on everythinggggggg.

element.style.display = 'none';
document.body.appendChild(element);

element.click();

document.body.removeChild(element);

} )

Backtrack X amount of lines when starting to tail log

Done

Active Logs nav section doesn't shrink after has had logs closed from it.

Add active lists groups pages.

Add no logs indicator to group pages and nav groups.

Add full logs list groups to dashboard page.

Clear hasNew when navigating to log output page, currently on happens if you are on log output page and a new line comes in.

Add functionality to clear output button

Add new indicator state for when log is inactive but is holding log output

Potential bug where output sits in paused log buffer, then the user stops watching, starts again, then paused and then starts again. The stale output from earlier will be added to the main output in the wrong position.

Dashboard list filtering.

Nav section overflow scroll management.

No logs matching search filter indicator on group pages and dashboard page.

Add dynamic title tag based on current page.

Sticky header on group pages when they overflow.

Nav group list is cut off at large list lengths.

Add focus highlights to buttons and anchors for keyboard based nav.

• Includes: Nav a and button tags, search inputs, group logs list items, log page buttons

Skip over closed nav groups when navigating using keyboard.

Extend search filter to log file path.
