You can use Notepad or Wordpad to open the NRPE log file located on your monitored server at Local Disk (C:) > NRPE_NT > bin > nrpe_nt.log. Each time the agent is asked to do something you will find a line in this file. At service start up the configuration files are read and if there are issues you may see some complaints, and further down the file is a read out on the commands sent to the agent from GroundWork.
If you are receiving timeout errors you may need to check your NRPE Windows machines firewall settings to see if there is access to the 5666 port. The steps below review how to create an Inbound Rule for this port.
WMI is installed on newer versions of Windows and can also be downloaded and installed on Windows NT. However, sometimes there are issues in getting WMI functioning. Most often these are easy to solve by ensuring authentication is set up correctly but in other cases there are corrupt or missing data structures on the remote host. There are a number of references on the Internet to assist with troubleshooting WMI problems. The plugins in this package assist with this troubleshooting by returning the WMI error code and (if possible) a description for that error.
If you are using the plugins without supplying -user and -pass arguments then the NRPE_NT service must be run as a user with administrative privileges on the host that the plugins are targeting. If you are using the plugins with -user and -pass arguments then that user must have administrative privileges on the target host.
In the case where you aren't using the -user and -pass arguments the use of a domain administrator account and then making sure that domain administrators have local administrative rights on each target host is the most efficient and maintainable solution. Another method involves defining a local account on each target host that uses the same account name and password as that passed to the plugin or as that being used to run the NRPE_NT service.
