it is fine to view console text via /consoleText URL which is using

 
                                                                 public void doConsoleText(StaplerRequest req, StaplerResponse rsp) throws IOException {
        rsp.setContentType("text/plain;charset=UTF-8");
        try (OutputStream os = rsp.getCompressedOutputStream(req)) {
            writeLogTo(getLogText()::writeLogTo, os);
        }
    }
