When having many RDS resources, metrics are not scraped

[DafuSHI]

I have an issue with prometheus cloudeye-exporter. if I'm testing it in my tenant with few databases, it works fine.

Here is my problem

When I launch my exporter I'm able to get metrics in prometheus but most of them are not scraped. I guess it is due to the huge number of metrics from lot of databases.

Would it be possible to apply a filter to get only one metric (e.g. : huaweicloud_sys_rds_rds048_disk_used_size) ?
