It depends what information you need to get out of it.
The Meraki dashboard is pretty good out of the box.
If you need additional information (or more historical information), I suggest looking for tools that utilize the Meraki API.
Note however there can be limitations depending on how many networks and devices you have as the API is rate limited.
Lately I've been using Statseeker. It's got all of the standard SNMP/Ping based polling options but also has an additional module (licensed separately) that can pull information directly from the Meraki dashboard via API.
