Unable to view all metrics

[madvimer]

I am using mongo exporter to extract metrics in prometheus. However i believe i cannot see all teh metrics( like index_counters_total and many others by going through the collector code). I am just starting the exporter without any additional arguments.
Attaching the stats that got generated. Is there something that i am missing ?

dcuStats.txt

I found this too using the docker hub eses/mongodb_exporter docker image https://hub.docker.com/r/eses/mongodb_exporter/
looks to me that the code
https://github.com/dcu/mongodb_exporter/blob/master/mongodb_exporter.go
have variable for the various mongodb.collect values
mongodbCollectConnPoolStats = flag.Bool("mongodb.collect.connpoolstats", false, "Collect MongoDB connpoolstats")
but missing some most notably
should add
mongodbCollectIndexCounters = flag.Bool("mongodb.collect.indexcounters", false, "Collect MongoDB indexcounters")
this code is 3 years old so am i missing something?
this fdoes seem to be in the fork:
