NetApp-Harvest 1.6 is out!
2 weeks ago
We have released Harvest 1.6 and it's available for download on ToolChest. There are three major changes in the new release, here's a short description of each of them:
Harvest Extension Manager (HEM)
We have added an entirely new component to Harvest: HEM allows you to customize and extend your poller without the need to touch Harvest source code. You can add your own scripts in any programming language and Harvest will run them during each polling session.
Harvest 1.6 comes with two extensions (NFS connections and SnapMirror replications collectors), but you can write your extension scripts. You might want to do that if you need additional post-processing on already collected metrics or if you want to collect metrics from some other source, or actually for any purpose. And you don't need to start from scratch: we have included in Harvest 1.6 templates for extension scripts in Python, Perl and Bash.
Check the NetApp Harvest Extension Manager 1.6 guideline for more info.
FlexGroup Capacity Metrics
Until now Harvest did not collect capacity metrics for FlexGroup volumes. This was due to ZAPI not providing sufficient information about FlexGroup volumes (e.g. the Cluster to which the volume belonged). Now we use RestAPI to get this missing data. This feature is supported for OCUM systems 9.4 or higher. By default it's disabled: see our Installation and Administration Guide to find out how to activate it.
Kudos to @Zoltan_Somogyvari for putting a lot of time and energy in testing this feature many many times!
Harvest will send poller statistics to AutoSupport every month. This new feature is important to us, Harvest developers. As we move forward and want to make the future Harvest more scalable, resource-efficient and robust, and for that we want to have some statistics about the many thousand of Harvest pollers, such as average API runtimes, fails nodes monitored, etc. This feature is by default enabled, but you can disable it in Harvest's configuration file.
We hope you will upgrade your Harvest soon and look forward to your feedback!

Great news Vachagan, thanks a lot!
2 questions on SnapMirror replications collector:
- is there a corresponding Grafana Dashboard included as well?
- does the collector support SVM-DR or only volume-based SnapMirror?
