How can I protect passwords that are stored in the nxlog config to access different systems. I am using the sql connector with a local sql account and it requires the username and password to be inputed into the config.
I think the feature you are looking for is in Enterprise Edition only.
When using im_odbc module, you can choose to use "Verified Connections", so you won't need to store any password in your config file.
What DB are you using?
