Message retention on Adapter engine in PI 7.3

Hello Guys,

I want to know whether we can retain the messages  -------- in RWB>>message monitoring>>Adapter Engine>>Database. for 30 days?

Actually I am able to see the messages for Integration server>>database for almost more than 15 days but got adapter engine I am able to see only 5 days messages.

I want to know what are default settings for the adapter engine messages rentention and also how I can set it to 15 to 30 days and is it advisable to change the settings or it will reduce the system performance on a large scale?

Thanks in advance.

Regards,

Rahul Kulkarni
