[Nagiosplug-devel] Re: long names in devices whith check_disk

[Orf, Tracy]

I am running nagios plugins on HP-UX 11.11.  As already noted, the
check_disk plugin on HP-UX doesn't work well with filesystem names
longer than about 20 characters.  If anyone is interested in using the
1.3 version with HP-UX, I've attached my changes to check_disk.c that I
am using.

 

Replace the main while loop with this:

 

        while (fgets (input_buffer, MAX_INPUT_BUFFER - 1,
child_process)) {

 

                if (!index (input_buffer, '/'))

                        continue;

 

                /* Fixes AIX /proc fs which lists - for size values */

                if (strstr (input_buffer, "/proc ") == input_buffer)

                        continue;

 

                /* Fixes HP-UX where long filesystem names cause the df
command

                   output to spread to two lines
*/

                if (sscanf (input_buffer, "%s %f %f %f %d%% %s",
file_system,

                     &total_disk, &used_disk, &free_disk, &usp, mntp) ==
6 ||

                    sscanf (input_buffer, "%s %*s %f %f %f %d%% %s",
file_system,

                                 &total_disk, &used_disk, &free_disk,
&usp, mntp) == 6 ||

                    sscanf (input_buffer, "%s %*s %f %f %f %d%% %s",
file_system,

                                 &total_disk, &used_disk, &free_disk,
&usp, mntp) == 1) {

 

                        if (strcmp(exclude_device,file_system) == 0 ||

                                (strlen(mntp) > 0 &&
strcmp(exclude_device,mntp) == 0)) {

                                if (verbose>0)

                                        printf ("ignoring %s.",
file_system);

                                continue;

                        }

 

                        /* filesystem info will be on the next line on
HP-UX

                           for long filesystem names */

                        if (strlen(mntp) == 0)  {

 

                                if (fgets (input_buffer,
MAX_INPUT_BUFFER - 1,

 
child_process)) {

                                        if (!(sscanf (input_buffer,

                                                       "%f %f %f %d%%

                                                printf ("Unable to read

                                                          command_line,
input_buffer);

                                                return result;

                                        }

command_line, input_buffer);

                        return result;

                }

 

                disk_result = check_disk (usp, free_disk);

 

                if (strcmp (file_system, "none") == 0)

                        strncpy (file_system, mntp, MAX_INPUT_BUFFER-1);

 

                if (disk_result==STATE_OK && erronly && !verbose)

                        continue;

 

                if (disk_result!=STATE_OK || verbose>=0)

                        asprintf (&output, "%s [%.0f kB (%d%%) free on
%s]", output,

                                  free_disk, 100 - usp, display_mntp ?
mntp : file_system);

 

                result = max_state (result, disk_result);

        }
