Problem

When trying to monitor my Microsoft Azure environment, you see the following error message in the Checkmk service Azure Agent Info:

Solution

You need to make sure that your Checkmk server can connect to the following two addresses of MS Azure: management.azure.com and login.microsoft.com

When a connection from your Checkmk server is impossible or times out, monitoring Azure will not be possible. You can quickly check this as the site user of your Checkmk site with either Telnet or Netcat:

OMD[mysite]:~$ nc -zv login.microsoftonline.com 443
OMD[mysite]:~$ nc -zv management.azure.com 443

The output of these commands should look like this:

OMD[mysite]:~$ nc -zv login.microsoft.com 443
Connection to login.microsoft.com 443 port [tcp/https] succeeded!

OMD[mysite]:~$ nc -zv management.azure.com 443
Connection to management.azure.com 443 port [tcp/https] succeeded!

If the output looks any different, you have to check the connection of your Checkmk server to Azure or contact your network people. More than once, there was a firewall blocking this connection.
