No way to clean filebeat registry file

[zionio]

Problem description

With graylog-collector-sidecar and filebeat as backend, there’s no way to clean up filebeat registry file (/var/cache/graylog/collector-sidecar/filebeat/data/registry) to prevent it from grows up in time, because in Graylog -> System/Collectors -> Manage Configurations -> Configure Beats Inputs, there is no clean_inactive options (ref).

After a long time and expecially with a large number of inputs, filebeat registry file may be a little problem… May i ask if there is another way (or trick) to clean it up without scheduling a job that stops/clean/start it?

Tnx
