Hi Dmitry,
i have built a catalog item that displays task infos (and more) across spaces for some important spaces. We have a lot of spaces/workers (>100)
The background is, among other things, to quickly find out which parameter on the ServerTask currently has which value over (ServerDashboard). We have standardized the parameter names.
An example:
esb_queue_s = Queue (RabbitMQ)
db_schema_t = Target sheme in Datawarehouse
db_table_t = Target table in the warehouse
…
By filtering e.g. queue, table … we can see very quick, what queue has data for what table, wich task is scheduled when …
Ultimately, the goal is to have a documentation board with all information at a glance. The tasks can also be started via this Catalog Item
Here some more infos:
But this are only Parametervalues of Projects (Project Metadata), not parameters of server task (these we need)
I know, parsing XML-Files would be a temporary solution.
(see this... Easymorph Server Command (List ServerTask Parametervalues) - Feature requests - EasyMorph Community - Data preparation professionals and enthusiasts)
To have a Web API for spaces, tasks, parameters ... would be great 
Regards,
Adrian
