Configure Datadog to collect StorageGRID snmp metrics and traps.

Configure Datadog

Datadog is a monitoring solution providing metrics, visualizations, and alerting. The following configuration was implemented with linux agent version 7.43.1 on an Ubuntu 22.04.1 host deployed local to the StorageGRID system.

Datadog Profile and Trap files Generated from StorageGRID MIB file

Datadog provides a method for converting product MIB files into datadog reference files required to map the SNMP messages.

SNMP Datadog configuration for Metrics

Configuring SNMP for metrics can be managed in two ways. You can configure for auto-discovery by providing a network address range containing the StorageGRID system(s), or define the IP's of the individual devices. The configuration location is different based on the decision made. Auto-discovery is defined in the datadog agent yaml file. Explicit device definitions are configured in the snmp configuration yaml file. Below are examples of each for the same StorageGRID system.

Auto-discovery

configuration located in /etc/datadog-agent/datadog.yaml

listeners:
  - name: snmp
snmp_listener:
  workers: 100  # number of workers used to discover devices concurrently
  discovery_interval: 3600  # interval between each autodiscovery in seconds
  loader: core  # use core check implementation of SNMP integration. recommended
  use_device_id_as_hostname: true  # recommended
  configs:
    - network_address: 10.0.0.0/24  # CIDR subnet
      snmp_version: 2
      port: 161
      community_string: 'st0r@gegrid'  # enclose with single quote
      profile: netapp-storagegrid

Individual devices

/etc/datadog-agent/conf.d/snmp.d/conf.yaml

init_config:
  loader: core  # use core check implementation of SNMP integration. recommended
  use_device_id_as_hostname: true  # recommended
instances:
- ip_address: '10.0.0.1'
  profile: netapp-storagegrid
  community_string: 'st0r@gegrid'  # enclose with single quote
- ip_address: '10.0.0.2'
  profile: netapp-storagegrid
  community_string: 'st0r@gegrid'
- ip_address: '10.0.0.3'
  profile: netapp-storagegrid
 community_string: 'st0r@gegrid'
- ip_address: '10.0.0.4'
  profile: netapp-storagegrid
  community_string: 'st0r@gegrid'

SNMP configuration for traps

The configuration for SNMP traps is defined in the datadog configuration yaml file /etc/datadog-agent/datadog.yaml

network_devices:
  namespace:  # optional, defaults to “default”.
  snmp_traps:
    enabled: true
    port: 9162 # on which ports to listen for traps
    community_strings: # which community strings to allow for v2 traps
      - st0r@gegrid

Example StorageGRID SNMP configuration

The SNMP agent in your StorageGRID system is located under the configuration tab, Monitoring column. Enable SNMP and enter the desired information. If you wish to configure traps, select the "Traps Destinations" and Create a destination for the Datadog agent host containing the trap configuration.
