A log viewer or log file viewer is a tool that allows you to view and analyze log files from a single system or from multiple systems in one place. If you are still using Tail or a text editor, you should switch to a log viewer that can parse your log files and display logs from multiple sources in tables, while providing effective tools to filter and search the log data. With XpoLog’s Log Viewer you can view and analyze multiple logs from multiple remote data sources, including Log4J, Log4Net, NLog, SysLog, access log, and more. The viewer offers multiple tools to access the data, including navigation, search, filters, live tail and more.
Universal Log Viewer with Multi-View Navigation
XpoLog Log Viewer offers simple tree-based navigation of logs across multiple systems and applications. Once the specific log, you can view it in the following formats:
- Tabular format – in this format the log entries are displayed in a table with columns, representing the various fields of each record. This offers a structural view of the log and the ability to easily sort the records by any of the fields/columns.
- List format – similar to a search result, this format displays each record as a separate line. In this format it is easier to fit more data into the view of the record.
You can easily navigate your way through the log using the toolbar navigation buttons. You can also open any number of tabs to view as many more logs as you wish and easily compare them. These logs can even come from different remote data sources. This is a fast and easy way compare between logs by navigating through the tabs that you have opened.
Pre-defined Log Filters – Search Log Data
When investigating logs, in most cases, we are looking for the same common log messages. XpoLog makes it easy to filter the log files using pre-defined log filters that are designed specifically for each log type. For example, access logs include predefined status filters such as “400 Bad Request”, “401 Unauthorized”, “402 Payment Required”, and more.
Ad-Hoc Search and Quick Filters
Quick Filter filters the log using specific terms, regular expressions, time range, and more. For more complex searches, you can use a regular filter to find specific data format, ID, problem or other pieces of information is crucial in any data mining process.
Real- time Live Tail – Stream Log Events
XpoLog log viewer offers a real-time view of your logs, retrieving your data as it comes in and refreshes automatically according to the time selected from the collection policy. This way, you are automatically seeing your data in near real time. You can even ask XpoLog to only update the latest data, rather than the entire file each time.
Using XpoLog’s search, you can correlate a transaction between different logs and view the results distributed over time. These correlations can for example show us when certain transactions started and when they ended. Also, such correlations can be real eye-openers in cases where different logs from different sources experience similar anomalies.
