A log is simply a data structure which is written only at the head (one could think of the entire disk as a log). Once the log is full, it is written into an unused part of the disk in a sequential manner.

Records information in a logical manner A log includes the date of each entry, schedules, daily notes, contacts, and references, as well as data collection, experimental procedures or methods, and more.

The basic anatomy of a log file includes: The timestamp ? the exact time at which the event logged occurred. User information. Event information ? what was the action taken.

Microservices logging is the practice of tracking and recording the activities of specific services in a distributed microservices architecture.

A "log" would include things such as dates or the time of day in order to show exactly when something occured or how often it occured over a period of time. "Record" is a broader term that means any recording of information, which includes logs.

Log is nothing but a file which contains a sequence of records, each log record refers to a write operation. All the log records are recorded step by step in the log file. We can say, log files store the history of all updates activities.

What Is a Log? It keeps the records, and the ordering of records, by when it's appended to the data structure. In a deterministic system, you can reconstruct the state of the systems at any time, by replaying the input in order for every single step of the input.

Centralized Logging Using Log Streams The common way to implement it is to stream microservice logs to a common queue. Distributed logging server listens to the queue and acts as log store. It provides search capabilities to search the trace.

A distributed system is composed of several applications calling each other to complete one operation. Each of these applications emits its own logs and often stores them in different locations.
