Abdessamad,

>> I removed the check "if {$errorcode} {set num_entries 0}" to have the error output logged.

Is there a reason, you prefer to remove the check? When nothing was matched by grep, the exit code is 1. The program enters the if condition and sets num_entries to 0.

If num_entries is not set, you'd encounter the error.

If you prefer not to use grep, you can probably use another command to scan through /var/log/apm for the string: errormsg "Reconnect"

Feel free to edit the code to match your requirements/environment.
