Python Get API randomly hits limit

johanoosterwaal — Wed, 24 Jun 2020 05:31:04 GMT

Hi,

working on a script for Meraki to count all wireless clients in a organization and there capabilities. But the code run randomly in to the API limit which is 5 per second. As a test is added allot of sleep timer to slow down the code but even that doesn’t work and i cannot figure out why.

import requests
import time
import os.path


headers = {'X-Cisco-Meraki-API-Key': xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'}
se = requests.session()

orgid = {'Test': '111111'}

cnt_80211b = 0
cnt_80211n = 0
cnt_80211ac = 0
cnt_80211ax = 0


try:
    timer = 0
    client_info = []
    for org in orgid:
        networks = 'https://api.meraki.com/api/v0/organizations/{}/networks'.format(str(orgid[org]))
        time.sleep(1)
        networks_data = se.get(networks, headers=headers).json()
        time.sleep(1)
        response = requests.request("GET", networks, headers=headers)
        time.sleep(1)
        print ("networks_data")        
        if response.status_code == 200:
            time.sleep(1)
            if networks_data == 'errors':
                time.sleep(5)
            else:
                for each in networks_data:
                    print(".....................................................")
                    print (each['name'])
                    print(".....................................................")
                    time.sleep(1)
                    clients = 'https://api.meraki.com/api/v0/networks/{}/clients'.format(str(each['id']))
                    clients_data = se.get(clients, headers=headers).json()
                    time.sleep(1)
                    response = requests.request("GET", clients, headers=headers)

I'm sorry, but you'll have to fix that formatting of your python script, if you want help with it.

Indeed thanks for the heads up!

Re: Python Get API randomly hits limit

Rasmus Hoffmann Birkelund — Wed, 24 Jun 2020 06:38:26 GMT

If have this in my code.

elif r.status_code == 429:
            print(f'Rate limited activated - Retrying after {r.headers["Retry-After"]}.')
            time.sleep(int(r.headers['Retry-After']))
            continue

So perhaps add the keyword continue.

Re: Python Get API randomly hits limit

johanoosterwaal — Wed, 24 Jun 2020 07:26:53 GMT

Thank you

Testing it now

Re: Python Get API randomly hits limit

Rasmus Hoffmann Birkelund — Wed, 24 Jun 2020 08:08:47 GMT

Also, a bit of advice, use environment variables for your API key, so you don't have it stored directly in your code. Adds some security, and flexibility, so that others can use the same script, without having to modify the source code directly.

LIke this.

import os

[...]

API_KEY = os.environ.get('MERAKI_API_KEY', None) 
if API_KEY is None:
   raise SystemExit('Please set environment variable MERAKI_API_KEY')
else:
   API_KEY = os.environ['MERAKI_API_KEY']

Assumes you have created the env-var MERAKI_API_KEY on your system.

Re: Python Get API randomly hits limit

johanoosterwaal — Wed, 24 Jun 2020 08:39:27 GMT

tested and the code runs a bit longer but still after some time:

clients_data
{'errors': ['API rate limit exceeded for organization']}

Thank you!

nice feature to add!

Re: Python Get API randomly hits limit

Rasmus Hoffmann Birkelund — Wed, 24 Jun 2020 08:49:35 GMT

I think you should clean up your code, for starters.

Instead of mixing requests() and sessions() use only one.

Use functions, and segment your code, for simplicity.

def GetOrgs(p_apiKey):
    for _ in range(MAX_RETRIES):
        try: 
            r = session.get(
                baseURL+'/organizations',
                headers = {
                    'Authorization': f'Bearer {p_apiKey}',
                    'Content-Type': 'application/json',
                    "Accept": "application/json",
                }
            )
            if r.status_code == 200:
                return r
            elif r.status_code == 429:
                print(f'Rate limited - Retrying after {r.headers["Retry-After"]}.')
                time.sleep(int(r.headers['Retry-After']))
                continue
            else:
                raise SystemExit(f'Unexpected status code: {r.status_code} returned from server.')
            
        except Exception as e:
            pprint(e)

(Note: I'm using the v1 beta api..)

For every session.get(), check the status code.

If it's 429, put in a sleep.

It's not the script that's being rate limited, it's the request that's being throttled.

totally agree on cleaning up the code and using functions. Not that good at Python but learning it on the go 🙂

do you perhaps have a complete code that i could use and modify?

Build a new script last night it works much better but still hits the API limit.

😅

# This is a Python 3 script to count the total unique client MAC addresses connected to MR access points for 
#  an organization during the last month.
#
# Usage:
#  clientcount.py -k <api key> [-o <org name>]
#
# Parameters:
#  -k <api key>     :   Mandatory. Your Meraki Dashboard API key
#  -o <org name>    :   Optional. Name of the organization you want to process. Use keyword "/all" to explicitly
#                       specify all orgs. Default is "/all"
#
# Example:
#  clientcount.py -k 1234 -o "Big Industries Inc" 
#
# Notes:
#  * In Windows, use double quotes ("") to enter command line parameters containing spaces.
#  * This script was built for Python 3.7.1.
#  * Depending on your operating system, the command to start python can be either "python" or "python3". 
# 
# Required Python modules:
#  Requests     : http://docs.python-requests.org
#
# After installing Python, you can install these additional modules using pip with the following commands:
#  pip install requests
#
# Depending on your operating system, the command can be "pip3" instead of "pip".

Re: Python Get API randomly hits limit

Rasmus Hoffmann Birkelund — Thu, 25 Jun 2020 13:35:14 GMT

The thing is, in the end, you can not avoid getting rate limited. If you submit more than 5 requests per second, it triggers the rate limit.

What you can do, is just be sure to handle it accordingly. That, or you can make sure to throttle your script manually but putting in sleep timers.

Or you can look into Action Batches

Hello RaresPauna,

As mentioned in the chat here is a Python class i created to help with the Meraki API ratelimit.

    def count_len(self, l):

            elif platforms[sys.platform] == 'Windows':
                os.system('cls')

            for future in futures:
                try:
                    r = future[1]
                    if r.status_code == 200:
                        if len(r.json()) != 0:
                            df = pd.json_normalize(r.json(), max_level=self.json_dept, errors='ignore')
                            for key, value in future[0].items():
                                df[key] = value
                            df = df.fillna(value=np.nan)
                            df = df.astype(str)
                            while 'next' in r.links:

                                    for key, value in future[0].items():
                                        dff[key] = value
                                    dff = dff.fillna(value=np.nan)
                                    dff = dff.astype(str)
                                    df = pd.concat([df, dff])
                    elif r.status_code == 404:

                    print(f"Error occurred during HTTP request: {err}")
                    continue
                end_df = pd.concat([end_df, df])
        self.response = end_df

This class takes a list of lists containing urls to check.
As an example, I'm using the url endpoint '/organizations/{Organization IDs}/networks' to collect all networks inside an organization.

lst = []
records = <Source from where to select>
for row in records:
    URL = f"/organizations/{<Organization IDs>}/networks"
    lst.append([URL, {}])

my_meraki_session = MyHTTPSession(ARG_APIKEY='123456789', URL_LIST=lst)
df_result = my_meraki_session.get_data()

Records is a list of the organization IDs that the API key can access.
There's an extra dictory [] after the url in the lst. This dictionary can be used to add more information to the Pandas dataframe later on. Things like organization names
Example:

records = Mysql_connection(dictionary=None).Select('ORGIDS', 'id', 'name' ,DISTINCT='DISTINCT')
for row in records:
    URL = f"/organizations/{row[0]}/devices"
    lst.append([URL, {'organizationId': row[0], 'organizationName':row[1]}])

MyHTTPSession is a custom HTTP session class that extends the requests.Session class. The class is initialized with two parameters: ARG_APIKEY and URL_LIST. The ARG_APIKEY is a mandatory parameter that represents the API key for the Meraki dashboard API. URL_LIST is an parameter that is a list of URLs that will be processed.

The class has several methods.

Init(self, ARG_APIKEY=None, URL_LIST=[]): This is the class constructor that initializes the class properties ARG_APIKEY, BASE_URL, urls, http, and headers. It also initializes the Retry and HTTPAdapter objects that will be used for handling retries and HTTP requests. It divides the URL_LIST into chunks and sets the chunk size to 5. It also sets default values for json_dept, data, and netlist_len.
Divide_chunks(self, l): This method is used to divide the URL_LIST into chunks of size 5. It takes in a list l as a parameter and uses a yield statement to return chunks of size 5.
Count_len(self, l): This method is used to count the number of chunks in the URL_LIST. It takes in a list l as a parameter and divides the list into chunks of size 5. It then calculates the number of chunks and sets the result to the netlist_len property.
Clear_console(self): This method is used to clear the console. It uses the os and sys modules to determine the platform and clear the console accordingly.
Process_bar(self): This method is used to display a progress bar. It calculates the percentage of completion and displays the progress bar in the console.
Get_data(self): This is the main method that retrieves data from the Meraki dashboard API. It initializes two data frames, end_df and end_df. It sets the JSON_dept and data properties if they are not already set. It sets the cnt property to 0 and displays the progress bar. It then iterates over the urls and creates a list of futures using the http.get method. It then iterates over the futures and processes the responses. If the status code is 200, it normalizes the JSON response using the PD.json_normalize method and adds any additional columns from the future. If there are more pages in the response, it continues to retrieve data until all pages are retrieved. It then concatenates the data frame df with end_df. If the status code is 404, it prints an error message. If there is an error during the HTTP request, it prints an error message and continues. Finally, it sets the response property to end_df.
