Businesses rely heavily on Microsoft Internet Information Services (IIS) servers to host their webpages and web applications, and also to store their files. It's important that your IIS servers, both web and FTP, are properly protected. One way to constantly monitor your servers' well-being is by deploying a log management tool that can parse, index, and make full use of IIS' W3C Extended format logs.
EventLog Analyzer, our log management tool, can extract everything out of all the logs in your IT environment. After breaking down the IIS server logs, EventLog Analyzer creates reports to provide you with actionable data. When you're looking to pick out one particular report among the thousands available, the clearly-classified report groups make sure you know exactly where to look.
How EventLog Analyzer helps you make the most of IIS logs
Supports IIS' W3C log format
EventLog Analyzer supports over 750 log sources , including the W3C Extended format. The solution facilitates this by collecting, parsing, indexing, and analyzing logs from your IIS servers without any additional configuration. It also generates reports after parsing the IIS server logs to provide you with actionable insights. Collect and analyze universal logs of any type regardless of their source and format.

Custom log parser
EventLog Analyzer's custom log parser automatically reads and extracts logs for unidentified fields to assist with log analysis. Even in unsupported or third-party app log formats, some basic fields are captured and you are given an option to add a new field if required. It recognizes and extracts the required fields from any raw log, regardless of the format. Use the default parsing capabilities for common fields and index the new fields using a custom log parser.

Parses key fields by default
The IIS log parser extracts fields like client and server IP address; date and time of the event; server name and port number; client-server URI query and stem by default. If you want to extract a new field from a log, you can train the parser to look for and extract it. Simply enter the standard pattern that the field follows, and the parser will begin extracting the necessary information.

Simplifies pattern creation
Don't spend time on manual pattern creation. EventLog Analyzer flexibly index logs using default fields or custom fields. It allows you to validate and edit the previously created patterns in no time. Automatically starts indexing and extracting the new field data when a pattern is generated the next time the same log type is imported. Patterns can be modified to index the new fields or to stop indexing the existing fields at anytime.

Correlates events in real-time
Correl" title="Correlates events in real-time">powerful correlation engine. The solution contains 30 predefined correlation rules to efficiently identify known attack patterns within your IIS logs. Additionally, you can also customize and define correlation rules to create new attack rules. If any malicious activity is detected in your IIS log server, the incident management system raises security alerts to the security administrator.

Frequently asked questions
IIS log parser is a command-line tool that takes the SQL-like expression as input and outputs the data that matches the user's query. Log parser can be used to query the log files, XML files, CSV files, and all other major data sources in Windows OS like Event log, Active directory, the Registry, and the file system.
Log file parsing helps in splitting up the unstructured raw log data into chunks for easier log data storage, manipulation, and analysis. It helps you to uncover the trends and patterns of log events to gain actionable insights.
Manually analyzing and spotting the security incidents is both exhaustive and quite impossible to get meaningful information from millions of log data. IIS log parsing tool like EventLog Analyzer collects, parses, and presents a whole lot of log data in a centralized intuitive GUI dashboard that makes the IIS log analysis process smoother and easier.
