I have a strange problem with Icinga 2, Icinga Web 2 and the Director. On all CentOS-servers I have installed the Nagios plugins (yum install nagios-plugins-all). Nevertheless, the commands for yum and check_linux_memory were missing on the CentOS systems. So I loaded them into the same path as the other commands and gave them sufficient rights with chmod +x. These commands can be executed locally via the console.
Icinga Web 2 displays results for yum, but for check_linux_memory in conjunction with CentOS 7 it displays "Check command' check_linux_memory' does not exist. If I do the same on a CentOS 6, the command works. Does anyone have an explanation for this? I have no idea, what the reason can be.
On Ubuntu, this works with check_linux_memory in the same way as on CentOS 6.
I used the director for auto-config of my hosts and a zone global-templates exists.
