Everything You Need To Know About Log Viewers

What Is A Log Viewer?

A log viewer is a software tool or application designed to help users easily read, analyze, and manage log files generated by various software systems, applications, or devices. Log viewers provide an organized and user-friendly interface that simplifies the process of sifting through these logs, making extracting meaningful insights and actionable information easier.

Software-as-a-Service (SaaS) log viewers are a specific type of log viewer that are web-based log management and analysis tools. They provide centralized log viewing and analysis proficiencies without the need for on-premises infrastructure. These platforms offer a cloud-based solution for collecting, storing, and analyzing logs from various sources. Generally, Saas log viewers possess the following features:

• Log Collection: These log viewers allow integrations to gather logs from different systems, applications, and cloud platforms. The configuration of these integrations will enable log data to be sent securely to the SaaS platform for centralized storage and analysis.
• Centralized Log Storage: To enable easy access and management of log data, logs gathered from various sources are stored in a centralized location within the SaaS platform.
• Real-time Log Visualisation: The majority of SaaS log viewers deliver real-time log visualisation. Therefore, when new log entries are created they are sent to the platform, allowing users to monitor log activity as it happens.
• Visualization and Dashboards: To allow accurate understanding and management of all your log data, Saas log viewers offer visualizations and dashboards to provide a graphical representation.
• Alerting and Notifications: To ensure proactive monitoring and a swift response to critical log events, users can set up alerts and notifications based on certain log events or conditions.
• Tool Integration: SaaS log viewers can allow the integration of other monitoring and incident management tools. This benefits the users as they enable seamless data exchange between different systems and improve overall observability.
• Compliance and Security: To ensure the confidentiality and integrity of log data, the vast majority of these log viewers provide security features. For example encryption options for data transmission and storage. Access controls to limit log access to authorized personnel, and compliance frameworks to meet industry-specific regulations.
• Historical Log Data: The ability to retain historical log data is a benefit to these log viewers as it allows users to analyze logs from previous timeframes. Which can be important for forensic analysis, trend analysis, and compliance audits.
• Scalability and Performance: SaaS log viewers are designed to manage large volumes of data and provide scalable infrastructure. They can effectively control high ingestion rates, indexing, and querying of log data, ensuring optimal performance even as log volumes grow.
• Cost-effective: Compared to self-managed log infrastructure, log viewers offer a cost-effective solution. They eliminate the need for upfront hardware or infrastructure investments. As well as reduce the operational costs of managing and scaling log management systems.
• Auditing and Compliance Reporting: To assist in compliance reporting and security audits. SaaS log viewers can provide auditing capabilities that will enable organizations to track user activities within the log management platform.
• Support and Maintenance: Finally, to ensure users have easy access to support if needed, SaaS log viewers offer technical support and maintenance services as part of the subscription package.

Log Viewer Tools: Log Management Platforms

Log management platforms are dedicated tools designed to collect, aggregate, and analyze logs from multiple sources. These platforms provide centralized log storage, powerful search capabilities, visualizations, and alerting mechanisms. The ELK Stack (Elasticsearch, Logstash, and Kibana) is a popular open-source log management solution. Other commercial options include Splunk, Graylog, Sumo Logic, and Logit.io. These platforms enable advanced log analysis, correlation, and monitoring across distributed systems.

Logit.io

Logit.io’s built-in log viewer is part of its larger centralized log management platform. They offer a centralized platform that ensures undertaking data analysis and error resolution on critical infrastructure is more efficient, affordable, and time-saving to scale alongside your operations as they grow in size and complexity.

Logit.io offers an extensive variety of integrations, such as Google Cloud (GCP), Microsoft Azure and Amazon Web Services (AWS), and many more. Also, to aid your team troubleshooting, the platform's live tailing feature enables you to visualize log events as they happen in a single real-time stream.

Splunk

Splunks log viewer tool is Splunk Log Observer. With this tool, you can effectively perform log-based examination and correlate these logs with Splunk Infrastructure Monitoring’s real-time metrics and Splunk APM’s traces in one place. Additionally, you can benefit from end-to-end visibility and the ability to perform quick and easy log-based investigations.

Windows Event Viewer

Windows Event Viewer is a built-in log viewer in the Windows operating system. The platform shows numerous types of event logs, including system, security, and application logs. Windows Event Viewer offers filtering options, the capability to search for specific events, and advanced log analysis features. It displays a graphical user interface (GUI) for navigating and viewing logs on Windows machines.

Log Viewer Tools: Remote Log Viewers & Console-based Log Viewers

Specialized services such as Papertail, Loggly, and others offer remote log viewing abilities via web-based interfaces. These platforms enable users to send their logs to their servers, supplying a centralized location for log storage and examination. They regularly provide search functionality, filtering options, and real-time log streaming, making it advantageous for distributed systems or cloud-based applications.

Video Studio Code

Videos Studio Code (VS Code) is an example of a remote log viewer. This tool is a popular code editor that supports log viewing and analysis via multiple extensions. The extensions provide syntax highlighting for log files, search functionality, filtering options, and the ability to navigate through log entries. Some log-related extensions for VS Code include Log File Highlighter and Log File IntelliSense.

Log viewer tools: log files

Finally, opening log files themselves is the most basic form of log viewing. Applications and operating systems regularly generate log files including information regarding their activities and events. These files are often located in a specific folder, and any user can open them using basic text editors such as Notepad.

Grep

A powerful command-line tool accessible on Unix-like systems that allows the user to find specific patterns within log files is Grep. The tool uses structured expressions to match patterns, making it flexible for filtering and exporting specific log entries. Also, Grep can be merged with other command-line tools to execute complex log analysis tasks.

Tail

Another command-line tool is Tail, commonly used to observe the last lines of a log file in real time. It’s especially useful for monitoring log activity as it happens. By default, Tail shows the last 10 lines of a file, but using the “-n” option will allow the user to specify a different number. For example, "tail -n 100" displays the last 100 lines of the log file.

Less

The Less command allows the user to observe log files interactively. It produces more advanced features when compared to a basic text editor, like backward and forward navigation. The tool is especially useful for observing large log files because it only loads the necessary portion of the file, making it more efficient.
