New view on monitoring (Dutch)

A while ago I was working on a monitoring project. A major part of the project was to focus on the ability to relate individual component failure to the impact on the business. Different levels of success were defined and monitoring objects are plotted to these different levels. Now the ICT-Architect published a paper on the subject (in Dutch). The article is available here:

Unexpected error

This one I have to share. I was working on some OCSP configuration and mistakenly selected an incorrect certificate for use as the signing certificate. While the first part is indeed correct “The signing certificate could not be selected”, the second part of the error gave me a smile.

Execution in parallel is essential for larger environments. PowerShell Workflow can perform ... READ MORE

Automation is ‘The new black’

This phrase can be used to call out the ... READ MORE

PoSh Remove previously managed SCOM agent

A while back a customer approached me if perhaps I knew a way to remove an agent entry from SCOM when the underlying server doesn’t exist anymore. Of course they could simply delete the agent entry from within the SCOM console manually, but the customer really wanted to include it in their automated decommissioning procedure which includes things like removing the server record from SCCM, removing the DHCP reservation and DNS records. ...
