Real time log viewer

This is a partial example to demonstrate the interaction between different reusable components to build an admin page in the WordPress back-end that shows a near-real-time display of the last 30 lines of my log files. This code will not work as is, as some of it depends on a larger architecture system. Some of the files have been shortened, and the usual file headers and copyright notices have been removed for brevity's sake.

Notable "features" of the below code: Project-specific logic is in Config files, making this reusable across several sites or projects. In fact, this is used across several sites by providing site-specific Config files that override the defaults. Logic is only coupled to a log file reader interface. The concrete implementation can be easily replaced by re-mapping the interface in the Dependency Injector to a different class which might even be outside of this particular plugin. All logic is contained within the Config file, even for the JS-specific stuff.

So, chances are good that this JavaScript file can be minimized and shipped and will probably not need a lot of changes later down the road. All general boilerplate code is in external components. Unit tests are written once, and are valid and usable across all sites that make use of them. Each new project will start with more than half its code already being unit-tested from the start.

Changes to the underlying infrastructure like when WordPress changes its Settings APIare contained within these external packages, and each relying project will probably only need a composer update once the changes are live.

In fact there are implementations of tail for Windows also eg. If windows is your thing you could try Tail for Win It's free, but not opensource. Looks ok from the description but I haven't tried it.

Actually, Log-Expert does what you want, plus a lot of nice feature. I have had good luck with the windows program mtail.

It does a very nice job of monitoring an active log. You can configure quite a few options but in general I have found the defaults work very well. I love the Kiwi Log Viewer. They were just bought out by Solarwinds -- I assume the product is still for sale or maybe they're giving it away for free now?

They're giving away a few other Kiwi products. If you install Cygwin on your Windows machine, you can run tail. I typically do this with TextPad. It has the option to monitor that a file has been modified. It is an option to either automatically update the window or to prompt you whether or not you want to reload the file.

All that is required is to open a text based log file, this program will check for any changes to the file and automatically display them on the screen.

The new changes are displayed in a bright color and then fade to the normal text color. It also automatically scrolls to the newest line. ABLogFile supports a very basic find function. This program was thought up in the early hours of the night a couple of weeks ago.

I was doing some work, a program that updated a file every couple of seconds. The hardest part of the project was how to organize the data in memory, so that it is easy to add new data, keep track of the changes, and quick to display the data.

What I ended up doing after a number of sleepless nights of coding, was to store the entire log file in memory, create an array of pointers that point to the starting position of each line, and another array of sections which keep track of the changes to the log file.

Another tricky bit was to work out what the line delimiter was in the file, the way that I ended up writing it was to search for a number of different delimiters, this part will definitely be redesigned shortly. Apart from the above mentioned, it was pretty straight forward. I believe this project to be of great benefit, I will be willing to add features as people suggest them.

This program currently does what was originally required by myself. So, please let me know of any features required.In ASDM 7.

If I instead choose the log buffer I can refresh that and see the messages updated there.

I suspect a bug that's not public-facing just yet. Open a TAC case to get your voice in the chorus to put pressure on getting it fixed. Thanks for fast reply. Does anyone know if there is a way to pipe the log matching an ACE to a text file in the meantime? I ended up downgrading to 7. That should get you through till cisco release the update to fix the bug.

ASDM appears to be running fine even though I didn't see any documentation that it would be supported. Buy or Renew. Find A Community. We're here for you!

Well there are a lot of utilities out there that can help a user to output the content of a file while the file is changing or continuously updating. Some of the most known and heavily used utility to display a file content in real time in Linux is the tail command manage files effectively.

As said, tail command is the most common solution to display a log file in real time. However, the command to display the file has two versions, as illustrated in the below examples. In the first example the command tail needs the -f argument to follow the content of a file. The second version of the command is actually a command itself: tailf. Usually, the log files are rotated frequently on a Linux server by the logrotate utility.

To watch log files that get rotated on a daily base you can use the -F flag to tail command.

The tail -F will keep track if new log file being created and will start following the new file instead of the old file. However, by default, tail command will display the last 10 lines of a file. For instance, if you want to watch in real time only the last two lines of the log file, use the -n file combined with the -f flag, as shown in the below example. Another interesting command to display log files in real time is multitail command.

The name of the command implies that multitail utility can monitor and keep track of multiple files in real time. Multitail also lets you navigate back and forth in the monitored file. To install mulitail utility in Debian and RedHat based systems issue the below command. To display the output of two log file simultaneous, execute the command as shown in the below example. Another interesting command, similar to multitail command is the lnav command.

Lnav utility can also watch and follow multiple files and display their content in real time. To install lnav utility in Debian and RedHat based Linux distributions by issuing the below command.

Watch the content of two log files simultaneously by issuing the command as shown in the below example. In this article, we showed how to watch data being appended in log files in real-time on the terminal in Linux.
