Currently, the filtering options to limit the scope for data scraping and display is mainly on Prometheus side via editing config files or adding some rules, but there is nowhere to filter from GPCC(Greenplum Exporter) side.
R&D will implement the filter for the upcoming release, which is expected to be on the release 7.7.0/6.17.0. Please follow us for updates on release notes: VMware Tanzu Greenplum Command Center 6.16 Documentation
