Chronosphere has announced $43.4 million in Series B funding, bringing the total raised to $55 million. This round was led by previous investors Greylock, Lux Capital and venture capitalist Lee Fixel with participation from new investor General Atlantic.

The company has also announced the general availability of its monitoring product. This release comes after a year in beta during which Chronosphere onboarded customers from emerging startups to later stage startups to well-known global brands.

Chronosphere’s product is powered by the open source metrics engine M3 that Chronosphere founders Martin Mao, CEO, and Rob Skillington, CTO, developed while at Uber.

Chronosphere not only allows customers to store and retrieve the massive amounts of monitoring data produced by cloud-native environments but it also does so with an order of magnitude more cost efficient than existing solutions.

Additionally, Chronosphere lets customers understand and control their spending, even as the data continues to grow.

According to the company, Chronosphere customers are able to end billing overages and reduce monitoring costs by up to 10 times.

Chronosphere’s monitoring product is provided as a hosted service, eliminating the need to manage monitoring infrastructure while maintaining 100% compatibility with cloud-native standards.
