Research direction

Start by tracing the plugin's InfluxDB metric-writing path and compare its verbose-log output with the sitespeed core example. Use the Lighthouse and Grafana examples as references; done means the emitted metrics use the intended measurement or series field rather than relying on the audit tag.

Written by the indexing model from the issue text.

Description

Hi there. I noticed that the plugin writes its metrics to InfluxDB differently than the core sitespeed app. This way you have to query the data in very unorthodox ways. See difference in sitespeed verbose log:

Sitespeed core:
(correctly uses series name for the measurement)

{
"tags": {
"device": "desktop",
"stage": "produktion",
"origin": "browsertime",
"summaryType": "summary",
"connectivity": "native",
"browser": "chrome",
"group": "www_enbw_com",
"testName": "www_enbw_com"
},
"seriesName": "firstPaint",
"point": {
"time": 1630409179532,
"median": 483
}
},

Lighthouse plugin:
(uses extra "audit" tag for the actual series name...and the series name is the unit???)

{
"tags": {
"audit": "first-contentful-paint",
"device": "desktop",
"stage": "produktion",
"origin": "lighthouse",
"summaryType": "pageSummary",
"page": "_unternehmen_",
"group": "www_enbw_com",
"testName": "www_enbw_com"
},
"seriesName": "numericValue",
"point": {
"time": 1630409179532,
"value": 1454.0010000000002
}
},

Also see the difference in Grafana query:

Any chance, this will be fixed in the future?
Cheers!
