[SOLVED] qm agent XXX ping - Shell return value in PHP

[MisterDeeds]

Dear all

I would like to check the agent status of a VM using a PHP script. I have created this as follows:

$connection = ssh2_connect($row['Ip'], $row['Port']);
ssh2_auth_password($connection, $row['User'], $row['Password']);
$stream = ssh2_exec($connection, "qm agent ".$row["VmID"]." ping");
stream_set_blocking($stream, true);
$stream_out = ssh2_fetch_stream($stream, SSH2_STREAM_STDIO);
$sshReturn = trim(stream_get_contents($stream_out));

print strlen($sshReturn) == 0 ? 'OK' : 'NOK';

Unfortunately, it is not clear to me how to get the return value. If the agent is running nothing is output, if it is not running the message "VM XXX is not running" appears.

Can someone help me?

Thank you and happy new year!

Hello,

To check if the agent is running, you can check the length of the output string.

If the agent of the VM running, there is no output, but if the VM is not running will print (VM 100 is not running).

I guess in your case, you have to set `if statement` to check the length of the output string and print the appropriate message.

Dear Moayad

Thank you for the answer. I have now figured it out. The message is written in the error stream. Here is my solution:

$connection = ssh2_connect($row['Ip'], $row['Port']);
ssh2_auth_password($connection, $row['User'], $row['Password']);
$command = "qm agent ".$row["VmID"]." ping";

$stream = ssh2_exec( $connection, $command );
$error_stream = ssh2_fetch_stream( $stream, SSH2_STREAM_STDERR );
stream_set_blocking( $stream, TRUE );
stream_set_blocking( $error_stream, TRUE );
$output = stream_get_contents( $stream );
$error_output = stream_get_contents( $error_stream );
fclose( $stream );
fclose( $error_stream );

print strlen($error_output) == 0 ? 'OK' : 'FAIL';

Thanks and best regards
