The Check_MK Notification Spooler (mknotifyd) has completely been rewritten. It now:
The global configuration for the spooler has changed. Your existing settings are still supported but have vanished from WATO. As soon as you create a new configuration that will override your legacy configuration.
The new checks that monitor the spooler require an update of the Check_MK Agent for Linux on the Check_MK server. It needs OMD based installaions paths. All spoolers will automatically be discovered. The new checks are mknotifyd and mknotifyd.connection.
The spooler write messages into var/log/mknotifyd.log. There are three log levels, which can be configured in the global settings of the spooler. We propose starting with the highest log level. Also a file var/log/mknotifyd.log is being written every 20 seconds. It shows the state of the spooler and its connections. This is being used for the monitoring of the spooler.
Note: To get the new mknotifyd running you need to reconfigure its global settings. Otherwise it will use the incompatible configuration of the previous version.
