Chronosphere, a startup that offers a cloud native observability platform, today announced that it has acquired Calyptia. While the company itself may not be a household name, Calyptia was founded by the creators of the Fluent Ecosystem, which includes the popular open-source observability projects like data collector Fluentd and metrics processor and forwarder Fluent Bit, both of which are part of the Cloud Native Computing Foundation's set of graduated projects. Like similar startups, Calyptia aimed to turn these projects into paid SaaS products.
