Problems Using Nagios with Proxies

The error is due to some reasons that may include.

  • Nagios XI requires external access for package installation and updates. If the proxies are configured incorrectly and package installation and the updates may not work properly.
  • Nagios XI code makes several internal HTTP calls to the local Nagios XI server to perform. These will not work properly if we deploy a proxy that is not configured properly. It can also result in a non-functional Nagios XI installation.


Initially, configure the yum and wget configurations to make XI installation work with a proxy.

Then update the following files, access the Nagios XI server in an SSH session.


proxy=http://someproxyserver:port/ # Shouldn’t need to be quoted, remember the trailing slash

proxy_username=myname # The username we authenticate to our proxy with, if applicable

proxy_password=mypass # The password we provide to our proxy, if applicable


http_proxy=http://myname:mypass@someproxyserver:port/ # All in one string this time

https_proxy=https://myname:mypass@someproxyserver:port/ # Only required if we have a HTTPS proxy

no_proxy=localhost,,,, # Hosts to exclude from proxying

Don’t quote any of these. Escape the special characters in passwords with backslashes.
