Product: OP5 Monitor
Release Number: 7.3.6
Release Date: January 24, 2017
Release Type: Micro
Previous Release: 7.3.5

What’s new

  • OP5 Appliance installations now get all disk allocated to the root partition. (Instead of a 45GB root partition and the rest of the disk allocated to /home.)
  • Executing a custom script by clicking on a Dynamic button on the Status Information page is now done without transferring the user to a blank page.
  • Naemon now refuses to start as root. Our start script have not used the root user for a long time, but it was possible for an user with root access to work around the start scripts and manually start Naemon as root. Doing that has never been recommended, and is now prevented.
  • The latest version of rrdtool (1.6) has stricter syntax rules. This caused errors in PNP graphs for the default OP5 Monitor graph templates. The default templates have now been updated. Customers with custom templates will need to adjust the following:

    • --upper should now be --upper-limit

    • --lower should now be --lower-limit

    • LINE[:number] for instance LINE1, LINE2, LINE3 does not accept LINE0

    • hrule commands that only use the WARN value without warn_min and warn_max have problems with ranged thresholds

  • PNP errors are now logged to Logger and can be found using the filter [log_messages] ident = "pnp"
  • Set more restrictive permissions on /opt/monitor/op5/merlin/merlin.conf for new installs. The permissions will be root:apache 640 on all new systems. We recommend that these permissions are applied manually on existing systems. An upgrade of OP5 Monitor will not change the permissions automatically because this file is a configuration file and we don't want to mess with local configuration on upgrade.

We have made a beta-version of OP5 Monitor for RHEL/CentOS 7 available as a virtual machine image, to give our customers a chance to test their own configuration and integrations as soon as possible and report any local problems found. More information is available in this howto. To update the existing beta-version, just run yum update.

How to upgrade

Click the update notification in the OP5 Monitor web interface, use yum update on the command line or download the latest tarball for offline installation.

Known issues

Rrdcached may fail to start after upgrade. See our support web for more details.
