Interface Conversion Panic #90

Closed zanes2016 closed 6 years ago

zanes2016 commented 6 years ago

We're running the latest docker version (mesosphere/mesos_exporter:latest) and we're seeing the following panic:

panic: interface conversion: prometheus.Collector is *prometheus.GaugeVec, not *main.settableCounterVec

goroutine 15 [running]:
main.newMasterCollector.func20(0xc0001526f0, 0x8f4be0, 0xc00000e0e0, 0x0, 0x0)

It seems to be due to whatever change was pushed into the build about 2 days ago.
