The Harvest2 team is pleased to announce the release of version 21.08.

With this release two of the most outstanding new features are; the addition of seven new dashboards; and a native to Harvest2 Docker deployment method.  You can read about all the steps and new features at https://github.com/NetApp/harvest,.

Here are some of the highlights and how they work.

New Features:

  • Make it easy to install Grafana, Prometheus, and Harvest with Docker Compose and auto-provisioned dashboards.
    • Full Docker setup included in Harvest download
    • Requires Docker 20.10.0 or higher
    • Download the latest version of [Harvest](https://github.com/NetApp/harvest#installation), then untar and cd into the harvest directory
    • Create a `harvest.yml` file with your cluster details.
    • Below is an example with annotated comments. You can modify as needed for your environment.

 

This config is using the Prometheus exporter [port_range](https://github.com/NetApp/harvest/blob/main/cmd/exporters/prometheus/README.md#parameters) feature so you don’t have to manage the Prometheus exporter port mappings for each poller.

```
Exporters:
  prometheus1:
    exporter: Prometheus
    addr: 0.0.0.0
    port_range: 2000-2030  # <====== adjust to be greater than equal to the number of monitored clusters

Defaults:
  collectors:
    - Zapi
    - ZapiPerf
  use_insecure_tls: true   # <====== adjust as needed to enable/disable TLS checks
  exporters:
    - prometheus1

Pollers:
  infinity: # <====== add your cluster(s) here, they use the exporter defined three lines above

    datacenter: DC-01
    addr: 10.0.1.2
    auth_style: basic_auth
    username: user
    password: 123#abc
  # next cluster ....
```
  • Generate a Docker compose file from your ‘harvest.yml’

bin/harvest generate docker full –output harvest-compose.yml

  • Start everything

docker-compose -f prom-stack.yml -f harvest-compose.yml up -d --remove-orphans

docker-compose -f prom-stack.yml -f harvest-compose.yml down

  • To Upgrade Harvest, use the restart command and a newer version of Harvest will be pulled if available.

docker-compose -f prom-stack.yml -f harvest-compose.yml restart

  • New Dashboards
    • Lun – Lun Details
    • Volume – Volume Details
    • Node – Node Details
    • Network – Network Details
    • Disk – Shows disk type, status, uptime, and aggregate
    • SVM – Details
    • SVM – Now with NFS v3 and v4 frontend

There are also more than 20 other enhancements and bug fixes.  See https://github.com/NetApp/harvest/releases for the full list of new features and fixes.
