Handling log management without logging tools is similar to programming from scratch instead of utilizing existing libraries and scripts - doable, but wasteful in terms of time and resources.
What is the first step in log management?
The first step in log management is to determine how to collect log data and where to store it. Your logs are aggregating data from different parts of the IT environment: operating system, firewalls, servers, switches, routers, etc. When it comes to storage, security systems such as firewalls and intrusion detection systems are the most demanding in terms of data volume they produce. Those systems typically generate dozens of EPS (events per second), which calls for a log collector that can handle the corresponding amount of logs.
Why is log analysis important?
Log analysis is arguably one of the most important parts of log management because collecting and storing log data doesn’t make any sense if you are not to make use of it. Log management tools automate and simplify the process of log data analysis, providing advanced ways to present your findings. Analytics reporting uses charts, plots, and other visuals to emphasize the correlations and similarities between events and data, making it easier to detect issues and track down their causes.
What are the different types of logs?
There are several types of log: some can be opened and read by human, while others are kept for auditing purposes are not human-readable. Audit logs, transaction logs, event logs, error logs, message logs are just some examples of different log files - each one serving a different purpose. They come in a broad variety of extensions, such as .log, .txt, or different proprietary extensions. Depending on the extension and readability, they can be opened with a standard text editor (such as Notepad) or word processing app (OpenOffice or Microsoft Word), or may require certain applications to be opened. Log management tools such as Graylog can be used to ingest logs coming from different applications or systems, view them and extract useful data from them.
How does log rotation work?
Log rotation helps address problems in the previous step by automatically renaming, resizing, moving, or deleting log files that are too large or too old. You can choose a time interval after which the log will be deleted, compressed to save space, or emailed to another location. This way, new storage space opens up for more recent log files. If you are already using our product or want to know how log rotation is performed in Graylog, here is the guide to log indexing and rotation for optimized archival in Graylog.
