HashiCorp Nomad

HashiCorp Nomad

Nomad is a flexible workload orchestrator that enables an organization to easily deploy and manage any containerized or legacy application using a single, unified workflow. Nomad can run a diverse workload of Docker, non-containerized, microservice, and batch applications.

HashiCorp Nomad by HTTP

Overview

This template is designed to monitor HashiCorp Nomad by Zabbix. It works without any external scripts. Currently the template supports Nomad servers and clients discovery.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • HashiCorp Nomad version 1.5.6/1.6.0

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

  1. Create a synthetic Nomad host. It should be one of the Nomad cluster members, load-balancing service (if cluster is used) or a single node in a selected Nomad region.
  2. Define the {$NOMAD.ENDPOINT.API.URL} macro value with correct web protocol, host and port.
  3. Prepare an ACL token with node:read, namespace:read-job, agent:read and management permissions applied. Define the {$NOMAD.TOKEN} macro value.

Refer to the vendor documentation about Nomad native ACL or Nomad Vault-generated tokens if you have the HashiCorp Vault integration configured.

Additional information:

  • Synthetic Nomad host will be used just as an endpoint for servers and clients discovery (general cluster information), it will not be monitored as a Nomad server or client, so that to prevent duplicate entities.
  • If you're not using ACL - skip 3rd setup step.
  • The Nomad servers/clients discovery is limited by region. If you're using multi-region cluster- create one synthetic host per region.
  • The Nomad server/client templates are ready for separate usage. Feel free to use if you prefer manual host creation.

HashiCorp Nomad Client by HTTP

Overview

This template is designed to monitor HashiCorp Nomad clients by Zabbix. It works without any external scripts.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • HashiCorp Nomad version 1.5.6/1.6.0

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

  1. Enable telemetry in HashiCorp Nomad agent configuration file. Set the Prometheus metrics format.

Refer to the vendor documentation.

  1. Prepare an ACL token with node:read, namespace:read-job permissions applied. Define the {$NOMAD.TOKEN} macro value.

Refer to the vendor documentation about Nomad native ACL or Nomad Vault-generated tokens if you're using integration with HashiCorp Vault.

  1. Set the values for the {$NOMAD.CLIENT.API.SCHEME} and {$NOMAD.CLIENT.API.PORT} macros to define the common Nomad API web schema and connection port.

Additional information:

  • You have to prepare an additional ACL token only if you wish to monitor Nomad clients as separate entities. If you're using clients discovery - token will be inherited from the master host linked to the HashiCorp Nomad by HTTP template.

  • If you're not using ACL - skip 2nd setup step.

  • The Nomad clients use the default web schema - HTTP and default API port - 4646. If you're using clients discovery and you need to re-define macros for the particular host created from prototype, use the context macros like {{$NOMAD.CLIENT.API.SCHEME:NECESSARY.IP}} or/and {{$NOMAD.CLIENT.API.PORT:NECESSARY.IP}} on master host or template level.

  • Some metrics may not be collected depending on your HashiCorp Nomad agent version and configuration.

HashiCorp Nomad Server by HTTP

Overview

This template is designed to monitor HashiCorp Nomad servers by Zabbix. It works without any external scripts.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • HashiCorp Nomad version 1.5.6/1.6.0

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

  1. Enable telemetry in HashiCorp Nomad agent configuration file. Set the Prometheus metrics format.

Refer to the vendor documentation.

  1. Set the values for the {$NOMAD.SERVER.API.SCHEME} and {$NOMAD.SERVER.API.PORT} macros to define the common Nomad API web schema and connection port.

Additional information:

  • The Nomad servers use the default web schema - HTTP and default API port - 4646. If you're using servers discovery and you need to re-define macros for the particular host created from prototype, use the context macros like {{$NOMAD.SERVER.API.SCHEME:NECESSARY.IP}} or/and {{$NOMAD.SERVER.API.PORT:NECESSARY.IP}} on master host or template level.
  • Some metrics may not be collected depending on your HashiCorp Nomad agent version, configuration and cluster role.
  • Don't forget to define the {$NOMAD.REDUNDANCY.MIN} macro value, based on your cluster nodes amount to configure the failure tolerance triggers correctly.
