Orthanc sending C-ECHO every 10 secs to peer

Hi Orthanc team,

We were recently testing Orthanc in an clinic settings trying to connect to their PACS. Although we were not querying the PACS via REST API but there was an C-ECHO every 10 seconds which possibly was trying to ensure the connectivity between orthanc and peer PACS.
Wondering if there is any settings which does this C-ECHO? Can we reduce it to a min or so?

It’s absolutely possible although there is no default setting. You perhaps need to write a simple python which running in a separated thread and calling c-echo via rest api.

Hello,

To the best of my knowledge, this behavior is not implemented in the core of Orthanc. You most probably have enabled some Lua script, some plugin or an external application that calls the REST API of Orthanc.

Would checking changelog in Orthanc might be doing it [checking all peer connected via C-ECHO]?
