Flamegraphs options not enabled despite default configure is set to true #213

Closed itsdax closed 5 years ago

itsdax commented 5 years ago

Flame graphs seem to not be enabled, and when clicking flamegraphs on the simple dashboard view, no data is being shown.

Is there still a dependency for vector-pmda to enable this feature? I'm currently unable to find any official details/docs for enabling the flamegraphs feature

Tested on v2.0.0-beta.1

@itsdax yes, there is still a dependency for vector-pmda in order to enable this, and you'll also need to ensure you have the configuration flag enableFlamegraphs: true set in src/app/config.js at build time.

If the widget is not visible, it means you have not included it in the build. If the widget is visible but greyed out, it means that Vector did not detect the PMDA running on the target system.
