I am able to retrieve apache web logs from one system and visualize them in kibana. However, we have more than one system that work as master-slave. > My Scenario: > If there are 3 systems A,B,C > A - Master (IP1: 192.165.17.1) > B - Slave 1 (IP2: 192.165.17.2) > C - Slave 2 (IP3: 192.165.17.3) In this setup, whenever system B access a webpage, the request is sent directly to the server (IP2). Similary whenever system C accesses a webpage, the request is sent directly to the server (IP3). However, whenever a login page is accessed by either of the slaves, the request is sent by master IP1. And further page access are directly encountered by respective slaves. > **Problem : Is there a way to find which slave is accessing the login page via master?** I would like to visualize inferences of logs made from a master-slave architecture. I am new to this, and grateful to find any help. ---
