In order to gain a detailed view of IT operations, organizations are using time-series monitoring tools, which are based on time-series databases optimized for collecting and analyzing time-stamped data at regular or irregular intervals. These tools provide high-resolution views of IT performance, enabling organizations to identify issues before they become major problems. By leveraging these tools, companies such as Houghton Mifflin Harcourt can monitor various types of metrics, gain insights into their systems, and optimize their operations for improved efficiency and reliability.
