Ambari

Agent Check

Overview

This check monitors Ambari through the Datadog Agent.

Setup

Installation

The Ambari check is included in the Datadog Agent package. No additional installation is needed on your server.

Configuration

Host

Follow the instructions below to configure this check for an Agent running on a host. For containerized environments, see the Containerized section.

Metric Collection

1. Edit the ambari.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your Ambari performance data. See the sample ambari.d/conf.yaml for all available configuration options.

   init_config:
   
   instances:
    ## @param url - string - required
    ## The URL of the Ambari Server, include http:// or https://
    #
    - url: localhost

2. Restart the Agent.

Log collection

Available for Agent versions >6.0

1. Collecting logs is disabled by default in the Datadog Agent. Enable it in your datadog.yaml file:

   logs_enabled: true

2. Edit your ambari.d/conf.yaml by uncommenting the logs lines at the bottom. Update the logs path with the correct path to your Ambari log files.

     logs:
       - type: file
         path: /var/log/ambari-server/ambari-alerts.log
         source: ambari
         service: ambari
         log_processing_rules:
             - type: multi_line
               name: new_log_start_with_date
               # 2019-04-22 15:47:00,999
               pattern: \d{4}\-(0?[1-9]|1[012])\-(0?[1-9]|[12][0-9]|3[01])
     ...

3. Restart the Agent.
