Bumps github.com/grafana/xk6-dashboard from 0.7.2 to 0.7.3.

Release notes

Sourced from github.com/grafana/xk6-dashboard's releases.

v0.7.3

xk6-dashboard v0.7.3 is here 🎉! This release includes:

• Breaking Changes
• Bug Fixes
• Enablers

Breaking Changes

As of v0.49.0, k6 includes xk6-dashboard as a built-in output extension. The name of the built-in module is the same as was the output name (web-dashboard) registered by the extension. Therefore, if you try to use it as an extension (for example, a newer version), you will get the following error:

$ ./k6 run -o web-dashboard script.js
.
.
.
ERRO[0000] invalid output extension web-dashboard, built-in output with the same type already exists

From now on, the registered name of the extension is again the previously used dashboard. Thus, it is possible (for example, built with xk6) to use a version of the xk6-dashboard that is newer than the one integrated in k6. In this case, the dashboard name must be used as the output name.

$ ./k6 run -o dashboard script.js

Related issue

Bug Fixes

• xk6-dashboard no longer works as an extension
• Report charts remain empty with short test
• Increase tooltip text size
• Selected timeframe resets on next data refresh

Enablers

The following enhancements enable various future dashboard UI feature developments.

SSE Stream Optimization

Previously on the SSE stream, the snapshot and cumulative events are sent as JSON objects, where the metric names are the property names. The property values are also JSON objects, in which the property names are the names of the aggregation function (avg, min, max, etc.). This two-level object hierarchy has not caused any problems so far, the amount of data has been acceptable.

Until now, aggregate counting per tag is still supported, but by default it is only allowed for the group tag. It would be necessary to turn on the aggregate calculation for the url and name tags as well (per URL graphs, summary, etc.). With the previous SSE stream format, this would significantly increase the amount of data. This would have a direct impact on the k6 memory requirement, so it is a problem.

Based on measurements, it can be concluded that using a two-level array structure instead of the two-level object structure used in snapshot and cumulative events significantly reduces the size of the events and thus also the memory requirement.

Therefore, instead of the two-level object structure, a two-level array structure implemented in the snapshot and cumulative events. The packages/model package also updated so it hides SSE stream changes from the rest of the dashboard UI.

Looks like github.com/grafana/xk6-dashboard is up-to-date now, so this is no longer needed.
