What are services and instances?
Services are groups of identical processes that perform a task together. Your "authentication" microservice, your
database instance or your Cassandra cluster are good examples of services and each unique process in those
groups is called an instance.
How do you charge services and instances?
We count how many services and instances were sending data during each hour of the month and charge you
€0.0390 for each service hour and €0.0094 for each additional instance hour.
The final total is rounded up to the nearest 2 decimal number.
How do test environments work?
The non-production environments have limited retention of 24 hours and can be used for monitoring staging,
development and pre-production environments, absolutely free of charge.
How often will you charge me?
We will charge your credit card at the beginning of every month for all usage incurred in the previous month.
Will you charge me if services are down?
Nope. You will be charged only the hours your services and instances were sending data.
What if I need a custom plan?
We can accommodate more metrics, spans and retention for you. Contact us through Intercom (the blue thingy on the
bottom-right corner of the screen) or via email at firstname.lastname@example.org
You can monitor up to three microservices for free with Kamon APM
