Nagios Support Forum

Having some issues installing the NCPA agent on a server 2008 R2 machine as administraor (and right-clicking and using the "run as administrator"). Hoping I can find some help. The installer finishes with no errors but service is not installed and this error is recorded when trying to run manually:

starting logging at level ERROR
Python exception encountered:
Internal Message: cannot import service module
Type => <type 'exceptions.NameError'>
Value => name 'DEFAULT_REUSE_ADDR' is not defined
Traceback (most recent call last):

ending logging

Working fine on 2016 servers. Have not tested 2012 Servers.


Linux Distribution and version?
Using the most current VMware OVA downloaded VM

VMware Image or Manual Install of XI?
Vmware Image

Are there special configurations on your system, ie; is Gnome installed? Are you using a proxy? Are you using SSL?
No special configs, but yes using SSL.

Any suggestions/help appreciated. Thanks!

Can you post yopur C:\Program Files (x86)\Nagios\NCPA\etc\ncpa.cfg file here so we can view the settings?
Does the Windows server have multiple Ethernet cards or IP addresses assigned to it?

The server only has one NIC with one IP Address.

I believe the built was broken for a short period of time. Most probably you have a corrupt exe. Remove NCPA, try re-downloading and re-installing the agent, and it should work. Let us know if this helped. Thank you!

This did fix the issue. Thank you!

Glad to hear everything is working!
