    SAM Linux/Unix scripting error

    don.hobson@cdk.com

      I have a simple SAM Linux/Unix script that when I attempt to run comes back with a scripting error. The return output is there (255965) but it's not being picked up or even seen. I have several other scripts like this which work fine using the same process but this one just doesn't pick up the value. Any thoughts?

       

      Command Line:

      perl ${SCRIPT}

      Script Body:

      $stat = `sudo /opt/vc/bin/getcntr -c natd.pinfo_shmem_free_entries -d vcgwnat.com`;

      print "Message: $stat\n";

      print "Statistic: $stat\n";

       

      Scripting Error: Script does not contain the expected parameters or is improperly formatted. 'Statistic' missing.

      Output: =====================================================

      perl /tmp/APM_1422259766.pl

      255965

          I haven't worked on many perl scripts but when I use Powershell I output the Message and Statistic with a number or description. SAM allows up to 10 different return values.

          e.g.

          print "Message.0: $stat\n";

          print "Statistic.0: $stat\n";

           

          or

           

          print "Message.some_description_here: $stat\n";

          print "Statistic.some_description_here: $stat\n";

            could you please post a sample output of the command `sudo /opt/vc/bin/getcntr -c natd.pinfo_shmem_free_entries -d vcgwnat.com` that you are running against the machine?

             

            statistic only accepts integer values afaik

              Output from machine -

              vcadmin@lasprodvelogw01:~$ sudo /opt/vc/bin/getcntr -c natd.nat_shmem_free_entries -d vcgwnat.com

              892044

              vcadmin@lasprodvelogw01:~$

               

              SAM output (Statistic value of '0' is from if/then statement below) -

              Output: =====================================================

              perl /tmp/APM_1257760654.pl

              Message:

              Statistic: 0

               

              I added a if/then statement to the script to see if anything was being picked up, doesn't appear so.

                I was asked today to update two metrics to a 'preferred' script. While testing, both now display exactly the same issue I've seen previously. The common thread appears to be “/opt/vc/bin/getcntr” for all these scripts. There is output from all scripts but it's not seen - no message, no statistic.
