Server Log Management

Log management is the practice of continuously gathering, storing, processing, synthesizing and analyzing data from disparate programs and applications in order to optimize system performance, identify technical issues, better manage resources, strengthen security and improve compliance.

server log management

A Log Management System (LMS) is a software solution that gathers, sorts and stores log data and event logs from a variety of sources in one centralized location. Log management software systems allow IT teams, DevOps and SecOps professionals to establish a single point from which to access all relevant network and application data. Typically, this log file is fully indexed and searchable, which means the IT team can easily access the data they need to make decisions about network health, resource allocation or security

Since data comes from a variety of sources, including the OS, applications, servers and hosts, all inputs must be consolidated and standardized before the organization can generate meaningful insights. Centralization simplifies the analysis process and increases the speed at which data can be applied throughout the business.

Both Security Information and Event Management (SIEM) and log management software use the log file or event log to improve security by reducing the attack surface, identifying threats and improving response time in the event of a security incident.

However, the key difference is that the SIEM system is built with security as its primary function, whereas log management systems can be used more broadly to manage resources, troubleshoot network or application outages and maintain compliance.

An explosion of data, as driven by the proliferation of connected devices, as well as the shift to the cloud, has increased the complexity of log management for many organizations. A modern, effective log management solution must address these core challenges:

Because log management draws data from many different applications, systems, tools and hosts, all data must be consolidated into a single system that follows the same format. This log file will help IT and information security professionals effectively analyze log data and produce insights used in order to carry out business critical services.

Data is produced at an incredible rate. For many organizations the volume of data continuously generated by applications and systems requires a tremendous amount of effort to effectively gather, format, analyze and store. A log management system must be designed to manage the extreme amount of data and provide timely insights.

Indexing within the log file can be a very computationally-expensive activity, causing latency between data entering a system and then being included in search results and visualizations. Latency can increase depending on how and if the log management system indexes data.

Log management is a time-consuming process that could drain resources from the IT organization. Many recurring tasks related to data collection and analysis can be automated using advanced tooling. Organizations should prioritize automation capabilities within any new log management tools and consider updating legacy solutions to reduce manual effort during this process.

Given the ever-growing data landscape, organizations should consider investing in a modern, cloud-based solution for their log management system. Using the cloud provides enhanced flexibility and scalability, easily allowing the organizations to expand or shrink their processing and storage capacity based on variable needs.

If a server fails, the databases may be left in a state where some modifications were never written from the buffer cache to the data files, and there may be some modifications from incomplete transactions in the data files. When an instance of SQL Server is started, it runs a recovery of each database. Every modification recorded in the log that may not have been written to the data files is rolled forward. Every incomplete transaction found in the transaction log is then rolled back to make sure the integrity of the database is preserved. For more information, see Restore and Recovery Overview (SQL Server).

In a log shipping scenario, the primary server sends the transaction log backups of the primary database to one or more destinations. Each secondary server restores the log backups to its local secondary database. For more information, see About Log Shipping.

In a database mirroring scenario, every update to a database, the principal database, is immediately reproduced in a separate, full copy of the database, the mirror database. The principal server instance sends each log record immediately to the mirror server instance, which applies the incoming log records to the mirror database, continually rolling it forward. For more information, see Database Mirroring.

Once your logs are ingested, process and enrich all your logs with pipelines and processors, provide control of your log management budget with indexes, generate metrics from ingested logs, or manage your logs within storage-optimized archives with Log Configuration options.

With Netwrix Event Log Manager, you can efficiently stay on top of Windows server logs across all computers in your network remotely, from a single desktop or laptop. Simply use an intuitive dialog box to specify which machines you need to collect logs from, the file system where the logs will be centrally stored, and the events you want to be alerted about. Then you will be notified in real time via email whenever a critical event occurs on any of those Windows servers, ensuring that no unauthorized activity goes unnoticed. Plus, you can prove to auditors that your logs are being properly archived.

Resolving application problems is easy when the right data is correlated and accessible. Retrace log management displays app and server errors in a centralized log with drill down and search capabilities, giving you the structure, access and context you need for faster troubleshooting and performance optimization.

Retrace has many built-in fields for basic server info, errors, web logs, and Windows events. The field explorer makes it easy to see all the fields that exist, giving you proper context around your logs.

Log Management Software are tools that deal with a large volume of computer-generated messages. It is also known as event logs, audit trails, and audit records. These software generally deal with log collection, storage, retention, rotation, analysis, searching, and reporting. Many such tools offer an advanced visual dashboard to help you quickly understand the data. They also provide archiving, real-time alerts, and automatic field parsing."}},{"@type":"Question","name":"\ud83d\udcbb Which are the Best Log Management Tools?","acceptedAnswer":{"@type":"Answer","text":"Here are some of the best log management tools:
