Loupe: The Best Analysis Tool for Log4Net
Log4Net is Powerful and Flexible, But Now What?
Log4Net is a powerful and flexible logging system which lets you organize the logging
done by your application into a Logger hierarchy which can be fed to various Appenders
filtered by severity level and even selecting different data elements to include
for each. But how do you decide what parts of the log event data to include,
or what severity level filter to apply so that you collect the data you need without
filling up the hard drive?
- You could just guess at it, but when you later
need the data to diagnose and fix a problem, you may find that a vital clue for that
problem was among the parts discarded by your best-guess filtering and never recorded.
- You could record it all, but that data could add up quick
and still leave you with the problem of what to do with the log files being recorded.
- You could spend time writing a tool to manage all these log files, purge
the old ones, and somehow get the data from your customers back to your support
staff and developers, but that's time you could better spend improving your product.
Loupe Makes It Easy
Loupe is an all-in-one application monitoring solution for .NET easily integrates
with Log4Net and other logging systems and also with the built-in Trace and Debug
capabilities. A Loupe Appender for Log4Net is included in the Loupe
distribution and adapters are also easy for you to write for other logging systems.
The Loupe Agent - which you can freely and easily deploy with your application
- can be integrated into your application by configuring the Loupe Appender
for Log4Net in your app.config. You don't need to pre-filter with Loupe;
you can just collect it all.
The Loupe Agent stores all of its collected data for an application session
in a compact format to reduce the disk space used and it automatically manages the
disk space used by logging on a client system.
Older session files will be automatically purged by age to maintain your targeted
limits, and long-running sessions will automatically roll over to a new file when
they reach a targeted size to allow older portions of that session to be discarded
You can also configure a minimum available space required so your logging will never
use up the last remaining space on the hard drive. When a user encounters
a problem with your application, the associated session data can be automatically
packaged and sent to your support staff or developers for analysis.
Analysis Made Easy
With the collected sessions in hand, Loupe helps you quickly select
sessions of interest to examine in detail and helps you find the problem area with
the higher-severity messages. Your organized hierarchy of Logger names is preserved
as the Category of each log message, and lets you instantly
filter the log message view by this hierarchy and also highlight a category of interest
so those messages stand out. The same instant filtering can also be done by
Class and Namespace, and a quick severity filter can be applied if needed, as well
as a custom filter when the instant filters just aren't powerful enough.
So, instead of filtering up front and risk throwing out important data you can apply
filters dynamically during analysis to narrow your focus to the data most helpful
for a particular investigation, and then bring other data back in when you need
to see what's happening in a larger context. Loupe also provides
a useful reporting system to help you analyze trends across many sessions.
Share Insight Quickly
Loupe also helps you analyze
errors across many sessions. List the most common errors across all collected
sessions of your product and break them down by category (i.e. by the Logger name)
so you can know what areas of your product need the most attention. You can
also analyze errors by product version, OS versions, and many other factors.
Whether you're working on an in-house system or a commercial product, you'll have real data
upon which you can make informed decisions.
