Tail Apache2 Log
helpful, it is also useful to watch logs in real time. Linux provides a command line tool that lets us do just that: tail. A real-time log monitoring in your browser Brief Introduction to Tail The primary purpose of tail is to grab the last few lines of a file (ten lines by default). To do so with any file would look like this: tail example.txt Tail also gives us a way

to watch files that are updated by other programs in real time: the -f flag. tail -f example.log While the -f flag is not exclusively for log files, it is the most common use case. When you are through following the log, you will need to press the Control and c keys at the same time in order to stop the tail process. Good Times to Tail: Apache Suppose there is a link on your site that, every time you click on it, real time log viewer gives you an Apache error. Depending on how your site is coded, the error page may not provide you with much information beyond the fact that there is an error message. First, start tailing the error log (n.b.: the following examples assume you have a cPanel server): tail -f /usr/local/apache/logs/error_log If the log is not updating frequently, it is a good idea to hit the spacebar a few times so the error you are trying to reproduce is set apart from previous errors. Then, go back to your browser and click on the link that was giving you the error. It should provide an entry in the error log that matches what you have seen in the browser. This is a surefire way to verify that the log entry corresponds to clicking on that particular link on the site. Good Times to Tail: Exim Another use for tail -f can just be to get a broad overview to see if something is wrong. Often, if you see the same error repeated over and over again in a log file, you can get an indication of a server-wide problem. Perhaps you are starting to hear multiple complaints that email addresses over several domains on your cPanel server are not receiving mail. A quick tail -f /var/log/exim_mainlog could show you in real time that multiple email accounts are all receiving the same error. As always, if you find an error you are not sure how to approach, our Heroic

Us Message Us About Us Linux Tips - How to view your Apache server error log in apache log viewer real-time! Posted on October 18, 2016October 18, 2016 One of the more annoying things about PHP is getting the "PHP white screen of death," whereby you (presumably) forgot to https://www.liquidweb.com/kb/how-to-watch-server-logs-in-real-time/ put a semicolon or closing bracket somewhere and so when you go to view your page, all you get is a blank screen…no error message, no information whatsoever. Annoying, right? The good news is that if you're doing your development on an internal web server that you have control over (because you're not doing your development on a production http://atglearning.com/global/linux-tips-view-apache-server-error-log-real-time/ machine that you don't, right?), if you can ssh into the server then you can view the error log in real-time. In many cases, it will reveal errors you may not be able to see on the page itself, and it will rid you of your white screen of death problem- it will even tell you which line the error is occurring on! So what do I do? Use PuTTY or some other ssh client to get into your server. We're assuming error logging has not been administratively disabled, so navigate to /var/log/apache2 and you should see a file called error.log. If you do, type this command: tail -f error.log This will show you a static log…until you try refreshing your PHP page. The log should update itself with the error message that's keeping you from getting any work done on the bottom of the window! You can keep this console window open on a second monitor perhaps, then every time you refresh your page you'll see errors instantly appear in the conso

SSH into the system. 2. http://www.bigappledesigns.com/blog/linux/how-to-access-apache-web-server-httpd-error-logs-for-amazon-ec2-linux-and-most-other-linux-varieties-also/ Then change to Superuser using the "su" command. 3. Then change directory https://petewarden.com/2008/06/22/get-a-real-time/ like so: cd /var/log/httpd/ 4. Now use this syntax at the command prompt: tail -n 300 error_log-20130602 | more This will show you the last 300 lines of the error log file error_log-20130602 The "| more" just splits up the output into more than one screen. So that you real time can the complete text of the error logs. The opposite of "tail" is "head" which instead of the last lines of errors, will show you the first few lines of errors.

CR I spend a lot of time developing on a remote server through an SSH connection, and I've found it tough to keep an eye on the error log file. Typically I've been running the tail unix command to look at the last 10 lines, but this only gives you a snapshot of the errors at that instant. If I wanted to see more, I had to run tail again. I knew there had to be a better way, something I was missing since I couldn't imagine unix wizards putting up with this. Luckily I was right. If you pass the -f or -follow option to tail it will continuously update, so you can see errors in real-time as the lines are written to the log file. This is perfect, I can see at a glance what's going on. To do the same, just open an SSH session to your remote server, and then type in the following command: tail -f /var/log/httpd/error_log The log file location varies on different flavors of Linux, and if you have access problems, make sure the logged-in user has high enough permissions to see it.
