obtaining MX memory utilisation by API

russell.sage — Fri, 01 Aug 2025 16:21:47 GMT

I am trying to obtain the memory utilisation for a MX450 using the organizations/{organizationId}/devices/system/memory/usage/history/byInterval with a Query parameter of the device serial number. Doing this in postman doesn't appear to work. According to documentation the parameter is "serials" but Postman won't accept this.

If I put the Key = serial and VALUE = <serial number> then the request works but it ignores the query entirely

Try this.

GET https://api.meraki.com/api/v1/organizations/{organizationId}/devices/system/memory/usage/history/byInterval

Headers:

X-Cisco-Meraki-API-Key: <your API key>

Content-Type: application/json

/organizations/{organizationId}/devices/system/memory/usage/history/byInterval?serials[]=XXXX-XXXX-XXXX

Would be the correct format

Hi thanks for the response. That is the API call I am using but when I use in Postman as you can seen in the screenshot Postman throws an error. I will try it in Python.

Guessing you replaced the {organizationId} already in the URL?

It would appear to be a postman issue. Works fine in Python. Many thanks
