LogDiver is a log file parser / viewer and is designed to quickly and easily import events from multiple application log files.
It gives you a consolidated view of your application log files across systems, servers and time zones.
It comes with a number of pre-defined extractors (such as Apache, Mac System Log, DB2, WebSphere, MQ), with the flexibility to define your own custom formats.
LogDiver also provides an awesome filtering capability that allows you to focus on the set of events that really matter.
LogDiver is an invaluable tool for system administrators, production support and developers.
What's New in Version 1.2.4
Fixed a couple of small bugs to make ready for Mavericks
You’d think that a log viewer would have the ability to open log files?! It appears that this app will open open Apache Web Server logs and nothing else, as there are no file handlers for basic .log format - making it a waste of $7.99.
This app works great!
The prior review was not an accurate review. The reviewer obviously didn't understand how to configure custom handlers. I almost didn't spent the $9.99 because of that review. That would have been a mistake. LogDiver is a very good app. It allows you to define the log format using regular expressions so this is very flexible. The handler configuration program detects how many regex groups you have and then allows you to map the regex groups to columns. It provides a predefined list of columns that match most of the columns you need to plus it allows custom columns. The program allows you to import multiple files that match the handler so if you have a rolling log you can import mylog.1, mylog.2, mylog.3 and mylog.log all at the same time and LogDiver will show what files were imported and the start and stop time of each time. It aggregates these results together and then allows you to filter the lines based on your criteria. I commonly use this program to filter on threads so I can see what is occuring in the context of one thread. LogDiver also allows you to easily filter on time by using a vertical slider where the top slider represents the start of time and the bottom slider represents the end of time to display in the view window. The program takes some time to parse the files and load them into columns but once it is loaded, it is pretty fast adding filters and scrolling. You can also save the import and filters into a file so you can easily reload the same data.
While the program is very useful, I would like to see an addition of line highlighting based on a regular expression. Ideally you can have multiple expressions associated with a different color. Also, the help could be more complete. But for $9.99, you can't go wrong with this app!
