I apologize beforehand if this is not the right place to put this.
I am developping an application in Windows with C++ and I want to send the changes from specific hosts to
a remote RedHat machine (system with nagios) through the "NSCA Win32 Client - send_nsca.exe" plugin.
In nagios system, I have passive services associated with the specific hosts.

If I put the information (with send_nsca syntax) in a file and if I make, for example:

Code: Select all

system("send_nsca.exe -H <host_NAGIOS_IP> -c send_nsca.cfg < file.txt");

This works fine. But, if I make:

Code: Select all

char send_nsca[512];
std::string my_string = std::string("<monitoring_hostIP>\t<passive_service>\t0\tOK - Value Received: 1|val=1");
sprintf(send_nsca, "echo %s | send_nsca.exe -H <host_NAGIOS_IP> -c send_nsca.cfg", my_string.c_str());
system((char *)send_nsca);

It gives me the following error:

'val' is not recognized as an internal or external command

If I take away the "|val=1" everything works fine.
The problem is that the echo is processing the '|' character as a 'pipe' and Windows cannot find a 'val' command.

Can you guys please help me with this question?
Thanks.

Try escaping it with ^

Thanks for replying. I already tried that, but it gives me the following message:

0 data packet(s) sent to host successfully.

You need to track down the code that outputs the message and add some debugging output to see why the value is not what it should be.

Thanks for everything. I already found a way. Basically, I open send_nsca.exe with a pipe in write mode and I write the message through the pipe (with the send_nsca syntax).

Interesting way of doing this, but cool. I will lock it up for now.
