Get Diagnostic JSON from the Last SSH Method Call

See more SSH Examples

Demonstrates the Chilkat Ssh.GetLastJsonData method, which copies structured diagnostic information from the most recently called method into a JsonObject. The only argument is the JsonObject that receives the information.

Background: This gives machine-readable diagnostics as an alternative to parsing LastErrorText, which is useful for logging or automated error handling. Many methods produce little or no additional JSON, so expect an object that is sometimes nearly empty. Authentication passwords and private-key passphrases are never included, so the output is safe to log.
