Retain changes in Netscaler 10.5 after reboot

If you have to do with Citrix Netscaler 10.5, you might have needed to change something on the installation, for example customize the layout of the authentication page. If you don’t take care a special way, your change will disappear after the next cold reboot of Citrix Netscaler. Continue reading

Monitoring Exchange 2013 mailbox databases with Check_MK

I confirm: the old check created some time ago (see this article) doesn’t work for Exchange 2013 installations. It seems to be be caused by significant changes on Powershell calls or cmdlets. I am having some troubles to get rid of the issue because I stepped away of Exchange business some time ago. A friend of mine is helping me to make the script working and I’ll hopefully publish a new version for Exchange 2013 very soon.

Stay tuned.

Fortigate checks for Check_MK updated to 2.2.3

Hi there,

I’ve updated the package to the version 2.2.3. Please consider updating to the new version some time. The change concerns only the check fortigate_ipsec and corrects a bug, that can cause an issue, when a IPSec tunnel doesn’t exist anymore. In this case the check can disturb the execution of other checks and make it not possible to re-execute the inventory.

The new version 2.2.3 is located as always on the check_mk exchange site.

Best regards
