General Deployment Collector – 24.001

Note: This version was initially announced as the minimum required (MGD) Collector. While it is still considered very stable, a slightly improved version 24.002 will be released Thursday, June 29th, and this will be the new required Collector. More information on MGD 24.002 to come.

GD Collector 24.001 will be available Friday, June 16th. The only change from GD Collector 24.0 is a minor bug fix with SSLCert collection. If you’re upgrading directly from the last required version, GD 22.005, here’s a summary of the exciting new features and improvements you can expect:

New Features:

  • Support for LogicMonitor’s Internal Service Checks.
  • Collector Caching – This enables the Collector to store data in your environment during periods where your collector is unable to deliver data to your LogicMonitor account. By default, Collector caching is enabled and configured to cache up to 30 minutes of data. See documentation for more information.
  • Support for Instance Level Properties, which allow you to set properties at the datasource instance level, or have them discovered via Active Discovery.
  • Collector Sizes – Different sizes correspond to different JVM max memory sizes, and make it easier to ensure that your Collector is configured to handle its intended monitoring load.
  • Poll Now – Selecting this button on the Raw Data tab will cause the Collector to immediately poll for new data. When troubleshooting, you can use this rather than wait for a full polling cycle to verify a datapoint. Note that “Poll Now” has no impact on alert evaluation and the data will not be shown in graphs.
  • Support for the Update History tab, which provides much more visibility into the outcome of scheduled Collector upgrades and make it significantly easier to remedy issues related to upgrades.
  • Support for Test Script, which enables you to tentatively apply scripts to a device and view their outputs. This increases efficiency and saves time during LogicModule development and troubleshooting.
  • Collector Downgrade – Enables you to revert back to a Collector’s previous version, as long as that previous version is higher than the minimum required version. This is a great excuse to experiment with more Early Release Collector versions since you can rest easy knowing any future upgrades are reversible.

Improvements:

  • JMX, WMI, HTTP, and Perfmon data collection improvements, resulting in an increase in collector capacity for these protocols.
  • Support for the QoS Netflow improvements.
  • Improved our Xen server detection to use the Xen API.
  • Increased the default script threadpool for optimal script collection performance.

Upgraded external libraries:

  • httpclient-4.5.2.jar
  • commons-logging-1.2.jar
  • httpcore-4.4.4.jar
  • commons-codec-1.9.jar
  • httpcore-nio-4.4.4.jar
  • httpasyncclient-4.1.1.jar
  • vijava to yavijava 6.0
  • Windows NTPQ.exe
  • AWS SDK to version 1.11.93
  • Jackson jars to version 2.6.6
  • Maria JDBC Driver to version 1.4.5

Note that this Collector no longer supports CentOS 5.
