@Singh, Sushmita[Non-Employee] Thanks for reaching out.
For sending the Linux logs to Sentinel, you have 2 options :
1) Install Log Analytics agent on your machine and have it forward the logs to your workspace.
2) Some device types that don't allow local installation of the Log Analytics agent, the agent can be installed instead on a dedicated Linux-based log forwarder. The originating device must be configured to send Syslog events to the Syslog daemon on this forwarder instead of the local daemon.
