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。

  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:

  • -iName of the Check_MK site on the server
  • -HHost Name of the agent
  • -pProtocol, which can be http or https (https by default)
