Merlin changelog

Changelog History

• v2021.11.1 Changes

  November 01, 2021

  ➕ Added

  • ➕ Added mon containerhealth that can be used to perform healthchecks when Merlin and Naemon is running in a container. This mon command is only shipped with the -slim packages.

  🔄 Changed

  • mon restart now checks if we are running on an systemd system. If not, a a SIGHUP is sent to Naemon process for reloading.

  ✂ Removed

  • 👉 showlog no longer support the --cgi-cfg= argument.

  🛠 Fixed

  • 🏗 OBS Build now correctly Requires: python2-PyMySQL instead of BuildRequires on EL8. This fixes a couple of mon scripts for example mon status install-time
  • 📦 Require php-cli for -apps packages ensuring mon node tree works correctly
  • 🔧 mon sshkey tools are now correctly using the user set during configure.
  • 📦 mon log now correctly works with the OBS built package.
  • 📦 spec: fixed misspelled dependency on python3-cryptography for EL8 slim packages
  • 👉 showlog now fallsbacks to using either /opt/monitor/etc/naemon.cfg or /etc/naemon/naemon.cfg for detecting the naemon.cfg file if no argument is provided. This ensures mon showlog works correctly most systems.
  • 🔀 Sync slim pollers encryption keys to any peers, prior to restart, when executing mon slim-poller register.

• v2021.10.2 Changes

  October 13, 2021

  🛠 Fixed

  • 🛠 Fixed an issue introduced in 2021.10.1 where mon oconf push would fail to work when pushing to pollers on systems with non upstream naemon paths.

  October 01, 2021

  ➕ Added

  • 📦 Community packages for CentOS/RHEL 7 & 8 are now generated with Open Suse Build Service
  • 🔄 Changelog has been added!
  • 🔧 Configure option --with-ls-socket allows one to configure where the livestatus socket is expected to be for the apps.
  • For slim packages, the merlin_cluster_tools script has been added. This script can be used with the cluster_update setting to automatically handle clustering.

  🔄 Changed

  • 🔧 Paths in the mon apps has been adjusted to configurable values. They are either fetched directly from the Naemon config, or from values set when running configure. This should make the mon apps less OP5 specific and work correctly with community installs.
  • The user/group in the systemd and logrotate files has been adjusted to match the values set with configure.

  ✂ Removed

  • 🚚 mon log fetch and mon log sortmerge has been removed, as these are broken and no longer used.

  🛠 Fixed

  • Correctly tokenize ipc_blocked_hostgroups so that the setting works as it should with multiple hostgroups defined.
