some graph in mongodb are not working

Hi Roman,

mongodb : 3.0 (primary+secondary+arbiter)
pmm-server: 1.0.5
pmm-admin add mongodb --replset repset --nodetype mongod --uri mongodb://user:pass@127.0.0.1/admin

There is still no graph of the Command Operations / sec metric. But I could get data from prometheus via the query. The related screens are as follow.

I have solved my problem and now it looks good… The default in Quick Ranges is “Last 1 hour”. When I changed more than 1 hour(e.g, Last 3 hour, 6 hour, etc…), datapoints are up in the graph:)

Thanks to the hint : https://github.com/alexanderzobnin/grafana-zabbix/issues/79
