Incorrect host name reported

Problem

The agent is working, but the [New Relic Infrastructure monitoring UI](https://docs.newrelic.com/docs/infrastructure/new-relic-infrastructure/infrastructure-ui-pages/infrastructure-compute-page-measure-resource-usage) shows the wrong hostname.

Solution

To set the correct hostname, try the following steps:

1. Edit the newrelic-infra.yml configuration file and add the override_hostname option, whose value is your expected hostname. For example:

   override_hostname: correct-host.domain.com

   Copy

2. Use your init system to restart the agent service:

   Restart the agent with SystemD

   Use SystemD commands with CentOS 7, Debian 8, RHEL 7, and Ubuntu 15.04 or higher:

   sudo systemctl restart newrelic-infra

   Copy

   Restart the agent with System V

   Use System V commands with Debian 7:

   sudo /etc/init.d/newrelic-infra restart

   Copy

   Restart the agent with Upstart

   Use Upstart commands with Amazon Linux, CentOS 6, RHEL 6, and Ubuntu 14.10 or lower:

   sudo initctl restart newrelic-infra

   Copy

   Restart the agent in Windows

   net stop newrelic-infra
   net start newrelic-infra

   Copy

Cause

The New Relic infrastructure agent tries to resolve its fully qualified domain name against a domain name server, which may not be properly configured or not controlled by the same user as the New Relic infrastructure agent.
