Adding static strings/separators into log format

If you’re looking to insert a separator ("|") or other arbitrary string into the syslog endpoint format:

1. Create a new request header in the UI (Configure–> Contents -->Headers) with the following fields filled in:

• Action: set
• Destination: any suitable header name (ie, http.X-Separator)
• Source: “whatever special character/string you want” (ie, “|” )

2. Once that’s created with the value you want, reference that header variable in the log format box (ie, in the example above, you would use req.http.X-Separator)
