Self-monitoring check Monitor backup - Check backup files now returns an unknown state instead of critical when no backups have been created yet. This update also improved its plugin output text.

The op5-backup now includes systemd service and timer units, which can be used to enable automatic backups by running systemctl enable --now op5-backup.timer. If an op5-backup scheduled job is configured in /etc/cron.d, it is advisable to remove that when the systemd timer is enabled.

Issues fixed

These are the issues we have fixed in this release:

Issue key Component Release description
MON-9490 Nacoma Clicking the Complete reimport link now prompts the configuration files to be loaded into the database, regardless of the file's timestamp. This change also improved the messaging by explaining how importing the configuration files into the database will affect the current settings.

MON-13132 GUI, Config Removed the complete reimport link from the GUI after restoring from backup. Reimport already happens during a backup restore, so performing it again is redundant.

OP5 Monitor 9.1

Released: 15 June 2022

To download ITRS OP5 Monitor, including all components, see ITRS Downloads.

Highlights

These are the highlights of this release:

  • Removed the urlize plugin since it was vulnerable to remote code execution.

  • Security hardening. The negate plugin has been updated to only accept commands and scripts to execute from the plugin path /opt/plugin/.

  • Security hardening has been improved to set the Apache policy to never include referrer URLs.

  • Improved security by disabling auto-complete on sensitive input fields.

  • Improved security of HTTP response headers.

  • The Secure and HttpOnly attributes are now set on the PHPSESSID cookie in the HTTP API.

  • The Kubernetes management pack now has fields for the namespace, while the namespace parameter for check_k8s_nodes check command has been removed.

  • Added the --ignore command-line option to the check_k8s plugin to exclude specified resource names from the check result.

  • Added capability to check multiple namespaces to check_k8s plugin.

  • Attributions, in Nagvis and Geomap, to Map and Data have been updated in accordance with terms and conditions with providers.

Breaking changes

These are the breaking changes in this release:

  • Pollers which depend on ssh-less test-this-check, particularly pollers with connect=no set on the master side will need to add the node setting accept_runcmd=1 in order to keep on using test this check.

  • The changes in the negate plugin may break the existing configurations if this plugin is used to execute applications and scripts outside the /opt/plugin/ path.

  • The changes in the Kubernetes management pack and check_k8s_nodes check command may break existing hosts configured using the Kubernetes management pack due to the addition of a custom variable for the namespace. To restore the functionality of the existing Kubernetes checks, add a custom variable named _NAME_SPACE with a value set to "" (blank) to the existing host configuration. It is also necessary to configure and activate the updated management packs, see Management packs.

  • The updates made to all NSClient checks to use the check_nrpe version 4 (version 2 is no longer working on EL8 operating systems) will have some implications, so take note of the following:

    • Configure and activate the updated management packs. See Management packs.

    • Import the updated check commands. See Import commands.

    • All servers with NSClient that are still using 512-bit keys for their NRPE SSL encryption require updating to use 2048-bit keys. For more information, see the check_nrpe article.
