When querying up for registered metrics in Console/Observe/Metrics, certain metrics are not showing up (return "No datapoints found"). These metrics include mcc_drain_err, mcc_state, etc

100%

1. start up a cluster 
2. run query e.g. mcc_drain_err in Console/Observe/Metrics 

No datapoints found 

Numerical result 

This only happens to metrics that are defined / registed with the type gaugeVec. It is discovered that for any vec (gaugevec, countervec), an initialization is needed, otherwise, it will not show up until updates: https://github.com/thought-machine/please-servers/pull/258
