This bundle contains a collection of supported VMware templates for proof-of-concept and production field deployments. Each VM contains all the necessary DataCore Swarm software as well as dependencies. The software packages are pre-installed and unconfigured.

This package contains:

• SwarmTelemetry OVF file

• SwarmClusterServices OVF file

• SwarmContentGateway OVF file

• SwarmSearch OVF file

What’s New:

• SwarmSearch/SwarmContentGateway/SwarmClusterServices: OEM-80 added support tools dependencies

• SwarmSearch: upgraded to java 1.8.0.362-B08 

• SwarmSearch: OEM-78 VM Swapiness set to 1 for Elasticsearch 

• SwarmTelemetry: TELE-9 and TELE-10 are new metrics in the Swarm Node View dashboard; this is mostly for support to see advanced UDP and CPU core usage info.

• SwarmTelemetry: TELE11 added a network IO chart to the Swarm Gateway dashboard. This requires a new job definition for the node_exporter service in prometheus.yml.

• SwarmTelemetry: TELE-12 replaced rate() with irate() functions in Gateway/System.

The bundle package can be found at DataCore Downloads.

Prerequisites

• A dedicated vSwitch for the Swarm Storage Network before importing VMs with the dual virtual network card.

• VMs are created on VMware ESX 7.0 and must be loaded into 6.7 U3 and above.

• If using vCenter, use the VMware vAPP OVF datacore-swarm-15.2.0-ESX.ovf to load the entire set of VMs in one command. Must include the nvram files as well.

• If not using vCenter, use an individual OVF for each template. This requires specifying the associated disk for each VM.

• A field engineer is required to configure the node_exporter service for the gateways in /etc/prometheus/prometheus.yml, an example is provided in the comments.

• A field engineer is required to configure and deploy the elasticsearch_exporter service on the SwarmTelemetry VM. The process is as follows:

  1. modify the Elasticsearch Node IP in /usr/lib/systemd/system/elasticsearch_exporter.service file

  2. systemctl daemon-reload

  3. systemctl enable elasticsearch_exporter

  4. systemctl start elasticsearch_exporter this will start the service and listen on port 9114

  5. modify /etc/prometheus/prometheus.yml and uncomment the elasticsearch job definition pointing at port 9114

  6. promtool check config /etc/prometheus/prometheus.yml to verify no typo errors were made in the config file.

  7. systemctl restart prometheus to activate the change

  8. Now you will see metrics populate the Swarm Search v7 dashboard.
