How can I extract Jibri Session ID in Jitsi

How to Extract Jibri Session ID ? I have integrated Jibri along with Jitsi and video/audio recording is working fine. But recording files( meetingname_timestamp.mp4 ) are by default storing under folder name of Jibri session ID. In below log(Jicofo.log), My jirbi session ID = rtxcucvtwynfjmsi hence My recordings are storing under the folder rtxcucvtwynfjmsi .
