To combat label cardinality explosions remove the type from metrics. This was most severe in the histogram for request duration, remove it there. It's also highlighted difference between grpc and forward code, where forward did use type and grpc didn't; getting rid of all that "fixes" that discrepancy Move monitor.go back into the vars directory and make it private again. Also name it slightly better Fixes: #4507 Signed-off-by: Miek Gieben <miek@miek.nl>
