How to push metrics use python2 requests?

[m986883511]

My product env only have python2, so I can not use prometheus-client, I search for a long time, I dont know how to push use python2 requests.

this is my demo code:

import requests
url = "http://192.223.44.211:9091/metrics/job/test_job/instance/host001"
headers = {'X-Requested-With': 'Python requests','Content-type': 'text/xml'}
type_str, metric_name, value = 'some explain', 'db_error', '1'
payload = "{}\n{} {}\n".format(type_str, metric_name, value)
res=requests.post(url, headers=headers, data=payload)
print(res.status_code, res.text)

output

[root@host061 ~]# /usr/bin/python /root/pushgateway/2.py
(400, u'text format parsing error in line 1: expected float as value, got "explain"\n')

Any one can help me

I solve it, but too simple.

import requests
url = "http://192.223.44.211:9091/metrics/job/test_job/instance/host001"
headers = {'X-Requested-With': 'Python requests','Content-type': 'text/plain'}
metric_name, value = 'db_error', 1 # value must be float
payload = "{} {}\n".format(metric_name, value)
res=requests.post(url, headers=headers, data=payload)
print(res.status_code, res.text)
