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.
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.
解决方法:
谢谢大家,但我做到了.
我做了这个命令:
top -b -n 10 -d.2 | grep 'cpu' | awk 'NR==3{ print($2)}'
