Hi @amir_darvish you probably need a flag [pmm-admin - PMM Administration Tool - Percona Monitoring and Management](https://docs.percona.com/percona-monitoring-and-management/details/commands/pmm-admin.html#enable-all-collectors) for metrics and also see a blog post related to this [Monitoring MongoDB Collection Stats with Percona Monitoring and Management](https://www.percona.com/blog/monitoring-mongodb-collection-stats-with-percona-monitoring-and-management/)
