Query the Infrastructure List with the API
If you’re a more advanced Datadog user, you may want to use the API to query general data about infrastructure—the kind of data that you can find in your infrastructure list or the host map. You can do this with an API GET request on the api/v1/hosts endpoint.
Examples
If, for example, you want to query general data from all your hosts that include the env:prod and role:elasticsearch tag, you can make the following API call with Python’s requests library:
import requests
s = requests.session()
s.params = {
'api_key': '<DATADOG_API_KEY>',
'application_key': '<YOUR_APPLICATION_KEY>',
'filter': 'env:prod,role:elasticsearch'
}
infra_link = 'https://app.datadoghq.com/api/v1/hosts'
infra_content = s.request(
method='GET', url=infra_link, params=s.params
).json()
To iterate over all the hosts in your infrastructure, use the following:
import requests
def iterate_all_hosts():
s = requests.session()
s.params = {
'api_key': '<DATADOG_API_KEY>',
'application_key': '<YOUR_APPLICATION_KEY>',
'include_muted_hosts_data': False,
'include_hosts_metadata': False,
'start': 0
}
infra_link = 'https://app.datadoghq.com/api/v1/hosts?count=1000'
while True:
response = s.request(method='GET', url=infra_link, params=s.params).json()
for host in response['host_list']:
yield host
if response['total_returned'] == 0:
return
s.params['start'] += response['total_returned']
for host in iterate_all_hosts():
print(host['host_name'])
