我想通过 SSH 检索 CPU 利用率百分比,我尝试了命令“top”,但它不会让我这样做。
我正在使用 CentOS 6。
我试过这段代码
$connection = ssh2_connect("IP", PORT);
ssh2_auth_password($connection, "root", "PASS");
$stream = ssh2_exec($connection, "top");
$errorStream = ssh2_fetch_stream($stream, SSH2_STREAM_STDERR);
// Enable blocking for both streams
stream_set_blocking($errorStream, true);
stream_set_blocking($stream, true);
// Whichever of the two below commands is listed first will receive its appropriate output. The second command receives nothing
echo "Output: " . stream_get_contents($stream);
echo "Error: " . stream_get_contents($errorStream);
// Close the streams
fclose($errorStream);
fclose($stream);
但它每次都给我一个错误:输出:错误:未设置TERM环境变量。
我正在使用 PHP。
