The RabbitMQ queue monitoring broke - because there were no queues.
Sounds weird? It kind of is. The #Perl script, which I've been using for #RabbitMQ monitoring for a very long time, checks for queues and their current values. But when a RabbitMQ server returned no queues at all, this #monitoring plugin just showed a weird (division by zero) error.

A new version of check_smart, a #monitoring plugin to monitor hard drives (HDD), solid state drives (SSD) and NVMe drives, is available.
The newest release, 6.18.2, is a bugfix release and fixes a regression introduced in 6.18.1. Using symbolic links as device path - for example in /dev/disk/by-id/ - were broken.

And because we can barely catch our breath anymore with yet another #Kernel #vulnerability, we just published our internal #Ansible playbook to mitigate against #copyfail and #dirtyfrag .

After running #PowerDNS for several years, it took until today, that I saw a completely new alert in our #monitoring.
The alert from the monitoring plugin told us about a "mandatory upgrade".
In my latest #blog post I got to the bottom of it: Where this information comes from and why this alert happened today.

check_smart 6.18.0 is out!
The newest release fixes a bug in the execution in the plugin's background, where the PATH definition was missing for the sudo command. To my current knowledge only #FreeBSD (or other #BSD) users might have run into that bug.
There's an important enhancement for servers running with #NVME drives, too. The plugin should now detect and alert on input/output errors.
