Network Device Monitoring uses profiles to tell the Datadog Agent the metrics and associated tags to collect. A profile is a collection of OIDs associated with a device.
By default, all profiles in the Agent configuration directory are loaded. To customize the specific profiles for collection, explicitly reference them by filename under
definition_file, or provide an inline list under
definition. Any of the Datadog profiles can be listed by name. Additional custom profiles can be referenced by the file path in the config, or placed in the configuration directory.
Note: The generic profile is generic_router.yaml, which supports routers, switches, etc.
Profiles allow Network Device Monitoring to reuse metric definitions across several device types or instances. Profiles define metrics the same way as instances, either inline in the configuration file or in separate files. Each instance can only match a single profile. For example, you can define a profile in the
init_config: profiles: my-profile: definition: - MIB: IP-MIB table: ipSystemStatsTable symbols: - ipSystemStatsInReceives metric_tags: - tag: ipversion index: 1 sysobjectid: '126.96.36.199.4.1.8072.3.2.10'
Then either reference it explicitly by name, or use sysObjectID detection:
instances: - ip_address: 192.168.34.10 profile: my-profile - ip_address: 192.168.34.11 # Don't need anything else here, the check will query the sysObjectID # and use the profile if it matches.
If necessary, additional metrics can be defined in the instances. These metrics are collected in addition to those in the profile.
Profiles can be used interchangeably, meaning devices that share MIB dependencies can reuse the same profiles. For example, the Cisco c3850 profile can be used across many Cisco switches.
