Nagios Core 4.0.8 has been released and is available for download. This release incorporates many improvements, notably:
- JSON API output has been better aligned with the standard, and output size limits have been lifted
- Check scheduling has been modified to prevent bunching checks at the start of their timeperiod
- Auto-rescheduling of checks has been reimplemented. This can be enabled by setting auto_reschedule_checks=1 in nagios.cfg, and adjusted by setting auto_rescheduling_interval and auto_rescheduling_window as described in the Core 4 Documentation. Auto-rescheduling smoothes the check schedule as it changes over time, and together with the previous improvements, helps to give a more uniform system load.
- Core workers handle variable assignments at the start of simple commands that otherwise don’t require a subshell, eliminating the need for most uses of env
A list of all enhancements and fixes included in this release is available in the changelog.
Thanks to all of the community members who reported bugs, contributed patches, and helped in testing the new release!
