This is how it should look (or similar, based on which captcha service(s) you are using) on the bottom of the GaneshBot captcha harvester.
It tells you the number of Captchas which were requested, how many are pending and how many are solved. It gives you both the total AND numbers for each individual 3rd party service.
If you don't see the same services as in the screenshot above, it is normal. You need to add the keys in the Settings tab. Check out the Settings section to learn how to do so.
