I have wrote a plugin for Nagios. That plugin should check the tomcat process. If I execute the by my self with the Nagios user everythig is ok. But in the GUI i can see this message: 
StatusUNKNOWN and info NRPE: Unable to read output 

what had i done wrong  ?? this is my code: 

<div class='indent'> 
#include <stdio.h> 
#include <stdlib.h> 
#include <sys/types.h> 
#include <sys/stat.h> 
#include <string> 
#include <iostream> 

using namespace std; 



main(void) 
{ 

char line_tmp[1000]; 
char find_stringII[]="tomcat"; 
int result=0, check_sum=0; 

FILE *tmp; 

return 0; 
/*------------------------------CHECK TOMCAT-----------------------------*/ 
system("ps -e | grep java > procs.tmp"); 

if((tmp = fopen( "procs.tmp", "r" ))== NULL) 
{ 
//cout << "Datei konnt nicht geöffnet werden" << endl; 
}else 
{ 
//cout << "Datei offen" <<endl; 
} 

do 
{ 
fgets(line_tmp, sizeof(line_tmp), tmp); 
//cout << line_tmp << endl; 
if( (strstr(line_tmp, find_stringII)) != NULL) 
{ 
result = 1; 
break; 
} 
else if( (strstr(line_tmp, find_stringII)) == NULL ) 
{ 
result = 2; 
} 
}while(!feof(tmp)); 

if( result == 1 ) 
{ 
//cout << "der Prozess: " << find_stringII << " ist vorhanden" << endl; 

} 
else if( result == 2 ) 
{ 
//cout << "der Prozess: " << find_stringII << " ist nicht vorhanden" << endl; 
check_sum++; 

} 


fclose(tmp); 


system("rm procs.tmp"); 


if(check_sum > 0) 
{ 
fflush(stdin); 
cout << "TOMCAT Prozess lauft nicht!!"<< endl; 
return 2; 
} 
else if(check_sum == 0) 
{ 
fflush(stdin); 
cout << "TOMCAT Prozess lauft.  " << endl; 
return 0; 
} 
} 

</div> 


p.s.: sorry for my bad english
