<html> <head> <style></style> </head> <body class='hmmessage'> Spent some more time with it & now getting a little closer I added this to my script on the dist server running the check: CLOCK=`date +%s` HOST=$1 SVC="Starlite Size" STATUS=$3 OUTPUT=$4 Changed the following lines exit 0 to STATUS=0 exit 1 to STATUS=1 exit 2 to STATUS=2 exit 3 to STATUS=3 the line(s) echo "OK. Free Space: `sudo rsh $1 df -v |grep starlite6 |head -1 | awk '{print $5}'`B, $percent%" to OUTPUT="OK. Free Space: `sudo rsh $1 df -v |grep starlite6 |head -1 | awk '{print $5}'`B, $percent%" running the script manually gives me : [1287522364] PROCESS_SERVICE_CHECK_RESULT;strXXXX;Starlite Size;2;Critical. Free Space: 51050B, 2% Up on the central server, I am still getting unknown but a value of null Closer I think but still not there. Does the central server have to have the exact same check script on it or in a passive check, does the central server only care about the results? Thanks, Steve </body> </html>
