What error message are you getting? Have you tried the check from the command line on the host? run nsclient++ /test and try a few commands Have you tried the check from the command line on the Nagios server? run the check_nrpe line replacing all the arguements with their actual values In the NSC.ini file, have you: uncommented the appropriate modules? set the allowed hosts line? Allowed arguements? restart the nsclient++ process after making these changes <div>On 4/21/06, ThomasC. <<a href="mailto:shoktai@gmail.com">shoktai@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I installed nsclient++. Put in checkcommands.cfg according to documentation the check : define command { command_name check_exchangeDB command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c CheckFileSize -a MaxWarn=15G MaxCrit=16G File=d:\Program Files\Exchsrvr\MDBDATA\priv1.stm File=d:\Program Files\Exchsrvr\MDBDATA\priv1.edb } What i dont understand is that it uses nrpe but the documentation doesnt show how to set the nrpe command. I had enabled in NSC.ini the needed module : [modules] ;CheckSystem.dll I have tried a nrpe handler like this [NRPE Handlers] check_exchangeDB=inject CheckFileSize MaxWarn=15G MaxCrit=16G File=d:\Program Files\Exchsrvr\MDBDATA\priv1.stm File=d:\Program Files\Exchsrvr\MDBDATA\priv1.edb but it doesnt work.
