Nutanix CE の Prism から起動中 VM の AHV ホストを取得する。

get_ntnx_vm-host.py

import sys
import json
import requests
import datetime

args = sys.argv
conf_file = args[1]

with open(conf_file, "r") as file:
    conf = file.read()
    conf = json.loads(conf)

prism_addr = conf["prism_address"]
prism_user = conf["user_name"]
prism_pass = conf["password"]

insecure_warn = requests.packages.urllib3.exceptions.InsecureRequestWarning

def main():
    base_url = 'https://' + prism_addr + ':9440/PrismGateway/services/rest/v2.0/'
    requests.packages.urllib3.disable_warnings(insecure_warn)
    s = requests.Session()
    s.auth = (prism_user, prism_pass)
    s.headers.update({'Content-Type': 'application/json; charset=utf-8'})

    hosts = {}
    data = s.get(base_url + 'hosts', verify=False).json()
    for entity in data['entities']:
        hv_uuid = entity['uuid']
        hosts[hv_uuid] = entity['name']

    ts = datetime.datetime.now()
    ts_str = ts.isoformat()

    data = s.get(base_url + 'vms', verify=False).json()
    for entity in data['entities']:
        if(entity['power_state'] == 'on'):
            vm_name = entity['name']
            hv_uuid = entity['host_uuid']
            hv_name = hosts[hv_uuid]
            to_csv_list = (ts_str, hv_name, vm_name)
            print(','.join(to_csv_list))

if __name__ == '__main__':
    main()
