You can enable and disable Trace nodes by setting properties in the server.conf.yaml integration server configuration file.
If the Trace node setting for an integration server is off, all Trace nodes in its flows are disabled. You can change the settings for Trace nodes in individual message flows; the settings are applied when you turn on Trace nodes for the integration server. If the Trace node setting for an integration server is on, the Trace node switch setting of each message flow determines the effective settings.
