Version 4.2.0

These features apply to Splunk Add-on for VMware Metrics version 4.2.0. For compatibility information, see Data collection planning and requirements in the Splunk Add-on for VMware Metrics manual.

New feature or enhancement	Description
Addition of the default performance metrics for host and VM	The following performance metrics are added to the default performance metrics list: Host performance metric: mem.average.usage.percent (indexing metric_name: vsphere.esxihost.mem.usage) VM performance metric: disk.average.usage.kiloBytesPerSecond (indexing metric_name: vsphere.vm.disk.usage)
Addition of hierarchy inventory data	Version 4.2.0 collects hierarchical data of vCenter entities as a part of inventory data. The hierarchy inventory data is used by visualizations in the Splunk Add-on for VMware.
Removal of biased language	Occurrences of biased terms, including whitelist, blacklist, master, and slave, have been replaced with appropriate non-biased terms. These changes do not include references to Splunk Enterprise terminology or product terminology. The following parameters from the inframon_ta_vmware_collection.conf file in the Splunk_TA_vmware_inframon package have been renamed: host_instance_whitelist > host_instance_allowlist vm_instance_whitelist > vm_instance_allowlist cluster_instance_whitelist > cluster_instance_allowlist managed_host_blacklist > managed_host_excludelist managed_host_whitelist > managed_host_includelist host_instance_blacklist > host_instance_denylist vm_instance_blacklist > vm_instance_denylist cluster_instance_blacklist > cluster_instance_denylist perf_entity_blacklist > perf_entity_denylist In addition, in the the vCenter configuration, you'll see inputs for Included hosts and Excluded hosts instead of Whitelisted hosts and Blacklisted hosts, to allow/block the performance data collection of certain hosts present in the vCenter server.

The field alias functionality is compatible with the current version of this add-on. The current version of this add-on does not support older field alias configurations.

Version 4.1.0

These features apply to Splunk Add-on for VMware Metrics version 4.1.0. For compatibility information, see Data collection planning and requirements in the Splunk Add-on for VMware Metrics manual.

New feature or enhancement	Description
Data collection through the add-on	Performance data of vCenter, Cluster, Datastore, ESXi Host, and virtual machines are ingested into the metrics index. Inventory, tasks, and events data of VMware vSphere are ingested into the events index. By default, add-on only collects certain fields of performance and inventory data. However, these performance fields/metrics are configurable using the <entity>_metric_allowlist into inframon_ta_vmware_template.conf.
Metrics allowlist/denylist to filter performance data	You can filter the performance metrics/fields of vCenter, Cluster, ESXi Host, and Virtual machines by configuring the respective <entity>_metric_allowlist and <entity>_metric_denylist in the inframon_ta_vmware_template.conf. For more information, see Configure Metrics Allowlist/Denylist to filter performance data collection.
Datastore performance metric collection	Performance data for VMware datastore metrics are ingested into the metrics index. The datastore performance fields are the required inventory fields (Capacity, FreeSpace, Used Percent), so the metrics allowlist/denylist functionality is not supported for datastore entities.

Version 4.0.0

These features apply to Splunk Add-on for VMware Metrics version 4.0.0. For compatibility information, see Data collection planning and requirements in the Splunk Add-on for VMware Metrics manual.

New feature or enhancement	Description
FIPS compliance and Python compatibility	The Splunk Add-on for VMware Metrics is FIPS compliant and is compatible with Python 2 and 3.
Coexistence with Splunk Add-on for VMware configuration	Existing Splunk Add-on for VMware users can install the Splunk Add-on for VMware Metrics on the same scheduler, indexer, and search head instances. The DCN instance for both add-ons needs to be different.
Collection Configuration page	You can configure the Splunk Add-on for VMware Metrics using the Collection Configuration page.
Data collection through the add-on	Performance data of vCenter, Cluster, ESXi Host and virtual machines are ingested into the metrics index. Inventory, tasks and events data of VMware vSphere are ingested into the events index. By default, add-on only collects certain fields of performance and inventory data. These fields are the default fields.
Data visualization	You can use the latest version of SAI to visualize the data collected by Splunk Add-on for VMware Metrics.

Upgrade from Splunk Add-on for VMware version 3.4.7

The Splunk Add-on for VMware Metrics collects performance data of vCenter servers, Clusters, ESXi hosts and virtual machines in the metrics index. The data collected and transformed by the add-on can be visualized using Splunk App for Infrastructure (SAI).

To upgrade to the Splunk Add-on for VMware Metrics, see Upgrade from Splunk Add-on for VMware version 3.4.7.

Upgrade from Splunk VMware Add-on for ITSI version 1.1.1
