New Release Available: OP5 Monitor version 7.3.6

January 25, 2017 Bryon Turcotte

The OP5 Development Team is proud to announce the newest micro release of OP5 Monitor version 7.3.6. This release brings some new improvements and fixes to the previous version 7.3.5 which will give our customers added capabilities and functionality when monitoring their IT systems.

 

What is new in OP5 Monitor version 7.3.6?

In the latest version of OP5 Monitor we primarily address application performance improvements and the overall quality of the product.

 


Bug Fixes & Performance Improvements:

  • 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.
  • Please note: 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.

 

A full list of features and fixes included in version 7.3.6 can be found in the new Release Note Archive on our Knowledge Base at https://kb.op5.com/x/JgcjAQ.

 

All improvements and fixes applied to OP5 Monitor are based on the requests and suggestions of our customers. We are constantly moving forward with the goal to make OP5 Monitor a more powerful, scalable, and hybrid solution to keep your organization proactive, productive and profitable.
