Collect replication slave information

[Sveta Smirnova]

Currently pt-stalk does not collect replication slave information. Please add support for it.

Before 5.7: SHOW SLAVE STATUS

5.7+:

select * from performance_schema.replication_connection_configuration join performance_schema.replication_applier_configuration using(channel_name);
select * from replication_connection_status;
select * from replication_applier_status join replication_applier_status_by_coordinator using(channel_name);

Those queries are always returning an empty result set in my environment.
Could you provide some configuration option I must enable in order to make them work?

Thanks

Do you run them on server, configured as slave?

[Carlos Salguero (carlos-salguero)]

Yes
