By default the counter widget does not alert or notify you about anything. It simply tracks a number using a POST-request similar to the heartbeat widget.
Every time you ping a counter widget it will increment it’s count by 1.
You can also explicitly send a count instead. An example:
Clicking on the cog icon on a counter widget reveals a couple of options. You can define upper and lower bounds. These are optional, but when setup Robodash will notify you when the count is out of bounds.
A great use case for counter widgets is monitoring the size of your background queues. It works great with Sidekiq.
