Agent-side log parsers extract structured data from raw logs before delivering to the VMware Aria Operations for Logs server. Using log parsers, VMware Aria Operations for Logs can analyze logs, extract information from them, and show those results on the server. Log parsers can be configured for both Windows and Linux VMware Aria Operations for Logs Agents.

If the syslog protocol is used, fields extracted by parsers are part of STRUCTURED-DATA according to RFC5424.
