Sentinel agent and syslog config RRS feed

  • Question

  • This may be more of a syslog config question than Sentinel: If i install the Sentinel agent on a Linux server and have it forward logs to Sentinel, can syslog also retain a copy of the logs locally on the Linux machine? Or does it just relay them through?

  • According to the documentation,

    "Applications will send messages that may be stored on the local machine or delivered to a Syslog collector. When the Log Analytics agent for Linux is installed, it configures the local Syslog daemon to forward messages to the agent. The agent then sends the message to Azure Monitor where a corresponding record is created."

    So if we follow this, the local machine and syslog agent would store the logs. And Sentinel collects those logs. So it looks like you would still have a copy of the logs on the local machine uder /var/log/syslog or /var/log/messages
