I set up scheduled compression as described in Howto.

Question is how to check if it really working?

I have found only 2 strings in entire server.log with word "compression"

2020-03-18 07:25:39,007 INFO  [org.dcm4chee.arc.compress.impl.CompressionScheduler] (EE-ManagedScheduledExecutorService-default-Thread-5) finished CompressionScheduler.execute()

time difference is less than a second. Its like the service does not do anything?

Did you configure a compression rule? E.g.:

No, nothing mentioned about that here https://github.com/dcm4che/dcm4chee-arc-light/wiki/Compression-of-Images

select compress_time from series where compress_time notnull; returns nothing

for me it worked by defining the AE it receives:

Hi.

I want to setup archive to compress every uncompressed recieved image into JPEG LS lossless during off hours, so i created the schedule (see image attached in first post), created a compression rule with "DICOM Transfer Syntax UID " 1.2.840.10008.1.2.4.80

is it correct?

ty.

I have made rule as on your screenshot (except compress delay)

And something is really happening, because daily size of studies on target pacs reduced during last days.

but "select compress_time" still returns nothing.

Does shceduled compression still not working? Does compresion rule applied instantly upon recieveing a study?
