Why Windows update monitoring is important
Regular updates are essential to close security gaps and ensure the stability of systems. However, without a suitable monitoring solution, critical updates can be overlooked, which can result in security risks and system failures.
Features of K&P Windows Update Check for CheckMK
- Monitoring of available updates: Both important and optional updates are recognized. Microsoft Defender intelligence updates appear under the optional updates.
- Sorting by severity: Clear overview of critical and less urgent updates.
- Individual alarm settings: WARN and CRIT levels can be set individually for different update types.
- Check for pending restarts: After the installation of updates, CheckMK issues an alert if a system still requires a restart. Individual WARN and CRIT values can be defined after how many hours CheckMK should issue an alert.
- Error notifications: Problems with the search for Windows updates are recognized and reported as CRIT errors.
- Detailed update history: Display of the last up to 80 installed updates and the last update time.
Technical details
Our check has been rewritten from scratch and uses Powershell to query the data. The execution of the check is controlled by the installed CheckMK agent on the system and is compatible with Windows Server versions 2012R2, 2016, 2019, and 2022. In addition, for all users of the CheckMK Enterprise, Cloud and Managed Service Edition, integration into the CheckMK Agent Bakery has been implemented, so that a cache interval of 3 hours, asynchronous execution and a timeout of 600 seconds are already preset.
Advantages for IT teams
- Time savings through automated update monitoring.
- Improved system security through prompt detection of update problems.
- Central management of all relevant information.
