How to solve the "Cannot fetch deployment URL via curl" error in check_mk

This article explains "ERROR Cannot fetch deployment URL via curl: Couldn't resolve host. The given remote host was not resolved ." Causes and solutions.

check_mkIs a tool that helps you configure the nagios monitoring server. Then, when configuring one of the machines, I encountered the following error:

1. ERROR Cannot fetch deployment URL via curl：Couldn't resolve host。The given remote host was not resolved。

This error occurs when I use the following command to register the machine to the monitoring server:

1. root@kerneltalks# /usr/bin/cmk-update-agent register-s monitor.kerneltalks.com -i master -H `hostname`-p http -U omdadmin -S ASFKWEFUNSHEFKG -v

Where:

• -sSpecify Monitoring Server
• -iName of the Check_MK site on the server
• -HHost Name of the agent
• -pProtocol, which can be http or https (https by default)
• -UUser ID of the agent that can be downloaded
• -SPassword. User's automatic operation password (when it is an automatic user)

It can be seen from the error that the command cannot resolve the DNS name of the Monitoring Servermonitor.kerneltalks.com.
