Hatena Co., Ltd. develops and operates multiple Web services centered around community services. Mackerel was developed as an in-house tool to optimize the management of the thousands of server systems required to operate these services. As Hatena's services and organizations grew and expanded, and the technology evolved, Mackerel became the center of Hatena's server management / monitoring while supporting development and operation teams.
After a complete makeover, Mackerel was released in 2014 as an SaaS-type server monitoring service packed with all the operational know-how gained from Hatena's development and operation experience. In pursuit of user-friendliness, the Hatena-based concepts "services" and "roles" were adopted to provide an operation model fit for the cloud era.
Mackerel is used to monitor thousands of systems within Hatena. The service continues to evolve by benefiting from the knowledge gained over time and from user feedback. Mackerel achieved a goal of more than 70 continuous months of function releases since the service's inception. Mackerel continues to evolve by aggregating monitoring know-how in the field, and by adapting to the evolution of technology such as containers and multi-cloud environments, advanced monitoring utilizing machine learning, and supporting infrastructure as code.
