Use this to poll the total number of active Cisco AnyConnect clients that are connected through your Meraki MX firewall. You will need to add your Org ID, the Network ID and your API key to the script. The script also relies on your AnyConnect clients using a unique subnet, you will need to enter part of that into the script as well. For example, if your AnyConnect clients are configured to use 10.254.1.0/24, you might consider adding "10.254.1.*" to the script.
As a note - this template's thresholds are set based on an MX250, which has a capacity of 1,000 active clients.
If you are unsure where to find your Org ID and Network ID, or need to generate an API key, you can get started with the Meraki API here: https://developer.cisco.com/meraki/api-latest/
