Custem Button on the WebUI

I am trying to get a button in nagios to enable/disable (a toggle) in the web-UI
Also a way to print the output of the command {service ssh status}
I am able to do this with linking to a php page that has a simple perl code. What I want is the following code in a Nagios page (.cgi file).
Code: Select all
<?php
if ($_GET['run']) {
# This code will run if ?run=true is set.
exec("sudo scripts/ssh-start");
}
if ($_GET['runf']) {
# This code will run if ?run=true is set.
exec("sudo scripts/ssh-stop");
}
$status = exec('sudo scripts/ssh-status');
$check = substr($status, 0, 8);
if ($check == "ssh stop"){
echo "<a href='?run=true'>Click Me! - ssh start</a>";
}
else{
echo "<a href='?runf=true'><img src='action.gif'></img></a>";
}
?>
But i'm having trouble with converting it. Does anyone have something like this?

This would need to be written in C if you want it as a .cgi file. Is there something about PHP you don't like or do you just prefer it to be a CGI?

The main problem now is that i want to display a bash command output in a page that is made in c (extinfo.cgi). and i don't want any popups.
The code below is what I'm working on now. But is has problems.....
Code: Select all
char i;
printf ("Checking if processor is available...");
if (system(NULL)){ printf ("Ok");}
else {
exit (EXIT_FAILURE);
printf("not ok");
}
printf ("Executing command ls...<br>\n");
//bash command: env
i = system ('env');
printf ("<br>The value returned was: %s.\n",i);
Code: Select all
Output:
Checking if processor is available...OkExecuting command ls...The value returned was: (null).
And I am not that skilled in programming, that's probaly the reason why I cant this to work.

The "system()" function in C will return the exit status of whatever you run, not the output. If you want to capture the output, check this guide out:
http://stackoverflow.com/questions/6462 ... get-output
Also keep in mind, while some of us on this forum are proficient in C, this is a Nagios forum. If you need assistance with the actual C language you should ask on a C forum.

Well. Thanks everyone for helping. I got it working. Maybe someone else can use it too.
I use this in my "extinfo.cgi" on the page "Process Info"
Code: Select all
printf("<tr><td>SSH Status</td>\n");
/* SSH Status */
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
FILE *fp;
char path[1035];
/* Open the command for reading. */
fp = popen("sudo ssh-status", "r");
if (fp == NULL) {
printf("Failed to run command\n" );
exit(1);
}
/* Read the output a line at a time - output it. */
while (fgets(path, sizeof(path)-1, fp) != NULL) {
char *output[10];
char *control_status = "";
char *control_string = "";
int ret;
control_status = path;
control_string = "ssh sta";
strncpy(output, control_status, 7);
output[3] = '\0';
ret = strcmp(output, control_string);
if(ret == 0){
printf("<td><div style='background-color: #00cc33; color:#fff; text-align:center;'>Enabled</div>\n");
}
else{
printf("<td><div style='background-color: #ff0000; color:#fff; text-align:center;'>Disabled</div>\n");
}
}
/* close */
pclose(fp);
printf("</td></tr>\n");
