I am using a windows server which is configured with forwarder.
Now I need all those logs on my desktop from where I want to monitor these logs.
Through indexers I will be passing those logs.
Please help me out for parsing such logs.
(Note: Latest version of windows server is being used)
Where is the forwarder configured to send the data (outputs.conf)?
You don't ever "need all those logs on your desktop"; they will go into an indexer which will do your bidding when you access it's data through your browser ("on your desktop").
The indexer will not "pass the logs"; the indexer is the final destination for them.
As far as "parsing", I assume you already have a "rex" command working so you can convert this to an automatic field extraction with props.conf:
