logrus.SetFormatter(Wrap(&logrus.JSONFormatter{
DisableTimestamp: true,
}, "SW_CTX"))

logrus.SetFormatter(Wrap(&logrus.TextFormatter{
DisableTimestamp: true,
}, "SW_CTX"))
logrus.WithContext(context).Info("test2")
Output: {"SW_CTX":"[,,N/A,N/A,-1]","level":"info","msg":"test1"} level=info msg=test2 SW_CTX="[,,N/A,N/A,-1]"
