How to monitor a Linux server and desktop remotely from web browser
|
||||
================================================================================
|
||||
When it comes to monitoring a Linux box, there are more than enough options to choose from. While there are many production-quality monitoring solutions (e.g., Nagios, Zabbix, Zenoss), boasting of fancy UI, monitoring scalability, comprehensive reporting capabilities, etc., these solutions are probably an overkill for most of us end users. If all you need is to check the basic status (e.g., CPU load, memory usage, active processes) of a remote Linux server or desktop, consider [linux-dash][1].
|
||||
|
||||
linux-dash is a web-based lightweight monitoring dashboard for Linux machines, which can display, in real-time, various system properties, such as CPU load, RAM usage, disk usage, Internet speed, network connections, RX/TX bandwidth, logged-in users, running processes etc. linux-dash does not come with any backend database for storing long-term statistics. Simply drop in linux-dash app in an existing web server (e.g., Apache, Nginx), and you are good to go. It is a quick and easy way to set up remote monitoring for personal projects.
|
||||
|
||||
In this tutorial, I am going to describe **how to set up linux-dash in Nginx web server on Linux**. Nginx is preferred over Apache web server due to its lightweight engine.
|
||||
|
||||
### Set up linux-dash on Debian, Ubuntu or Linux Mint ###
|
||||
|
||||
First, install Nginx web server with php-fpm.
|
||||
|
||||
$ sudo apt-get install git nginx php5-json php5-fpm php5-curl
|
||||
|
||||
Configure Nginx for linux-dash app by creating /etc/nginx/conf.d/linuxdash.conf as follows. In this example, we are going to use port 8080.
|
||||
|
||||
$ sudo vi /etc/nginx/conf.d/linuxdash.conf
|
||||
|
||||
----------
|
||||
|
||||
server {
|
||||
server_name $domain_name;
|
||||
listen 8080;
|
||||
root /var/www;
|
||||
index index.html index.php;
|
||||
access_log /var/log/nginx/access.log;
|
||||
error_log /var/log/nginx/error.log;
|
||||
|
||||
location ~* \.(?:xml|ogg|mp3|mp4|ogv|svg|svgz|eot|otf|woff|ttf|css|js|jpg|jpeg|gif|png|ico)$ {
|
||||
try_files $uri =404;
|
||||
expires max;
|
||||
access_log off;
|
||||
add_header Pragma public;
|
||||
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
|
||||
}
|
||||
|
||||
location /linux-dash {
|
||||
index index.html index.php;
|
||||
}
|
||||
|
||||
# PHP-FPM via sockets
|
||||
location ~ \.php(/|$) {
|
||||
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
|
||||
fastcgi_split_path_info ^(.+?\.php)(/.*)$;
|
||||
fastcgi_pass unix:/var/run/php5-fpm.sock;
|
||||
if (!-f $document_root$fastcgi_script_name) {
|
||||
return 404;
|
||||
}
|
||||
try_files $uri $uri/ /index.php?$args;
|
||||
include fastcgi_params;
|
||||
}
|
||||
}
|
||||
|
||||
Disable the default site configuration.
|
||||
|
||||
$ sudo rm /etc/nginx/sites-enabled/default
|
||||
|
||||
Configure php-fpm by editing /etc/php5/fpm/pool.d/www.conf. Make sure to edit "user", "group" and "listen" directives as shown below. You can keep the rest of the configuration unchanged.
|
||||
|
||||
$ sudo vi /etc/php5/fpm/pool.d/www.conf
|
||||
|
||||
> . . .
|
||||
> user = www-data
|
||||
> group = www-data
|
||||
> listen = /var/run/php5-fpm.sock
|
||||
> . . .
|
||||
|
||||
Proceed to download and install linux-dash.
|
||||
|
||||
$ git clone https://github.com/afaqurk/linux-dash.git
|
||||
$ sudo cp -r linux-dash/ /var/www/
|
||||
$ sudo chown -R www-data:www-data /var/www
|
||||
|
||||
Restart Nginx web server as well as php5-fpm to finalize installation.
|
||||
|
||||
$ sudo service php5-fpm restart
|
||||
$ sudo service nginx restart
|
||||
|
||||
### Set up linux-dash on CentOS, Fedora or RHEL ###
|
||||
|
||||
On CentOS, it is necessary to [enable EPEL repository][2] first.
|
||||
|
||||
Install Nginx web server and php-fpm component.
|
||||
|
||||
$ sudo yum install git nginx php-common php-fpm
|
||||
|
||||
To configure Nginx for linux-dash app, create /etc/nginx/conf.d/linuxdash.conf as follows.
|
||||
|
||||
$ sudo vi /etc/nginx/conf.d/linuxdash.conf
|
||||
|
||||
----------
|
||||
|
||||
server {
|
||||
server_name $domain_name;
|
||||
listen 8080;
|
||||
root /var/www;
|
||||
index index.html index.php;
|
||||
access_log /var/log/nginx/access.log;
|
||||
error_log /var/log/nginx/error.log;
|
||||
|
||||
location ~* \.(?:xml|ogg|mp3|mp4|ogv|svg|svgz|eot|otf|woff|ttf|css|js|jpg|jpeg|gif|png|ico)$ {
|
||||
try_files $uri =404;
|
||||
expires max;
|
||||
access_log off;
|
||||
add_header Pragma public;
|
||||
add_header Cache-Control "public, must-revalidate, proxy-revalidate";
|
||||
}
|
||||
|
||||
location /linux-dash {
|
||||
index index.html index.php;
|
||||
}
|
||||
|
||||
# PHP-FPM via sockets
|
||||
location ~ \.php(/|$) {
|
||||
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
|
||||
fastcgi_split_path_info ^(.+?\.php)(/.*)$;
|
||||
fastcgi_pass unix:/var/run/php-fpm.sock;
|
||||
if (!-f $document_root$fastcgi_script_name) {
|
||||
return 404;
|
||||
}
|
||||
try_files $uri $uri/ /index.php?$args;
|
||||
include fastcgi_params;
|
||||
}
|
||||
}
|
||||
|
||||
Next, configure php-fpm by editing /etc/php-fpm.d/www.conf. In this file, make sure to set "listen", "user" and "group" fields as below. You can leave the rest of the configuration unchanged.
|
||||
|
||||
$ sudo vi /etc/php-fpm.d/www.conf
|
||||
|
||||
> . . .
|
||||
> listen = /var/run/php-fpm.sock
|
||||
> user = nginx
|
||||
> group = nginx
|
||||
> . . .
|
||||
|
||||
Download and install linux-dash under /var/www.
|
||||
|
||||
$ git clone https://github.com/afaqurk/linux-dash.git
|
||||
$ sudo cp -r linux-dash/ /var/www/
|
||||
$ sudo chown -R nginx:nginx /var/www
|
||||
|
||||
Finally, restart Nginx web server as well as php-fpm, and set them to auto-start upon boot.
|
||||
|
||||
$ sudo service php-fpm restart
|
||||
$ sudo service nginx restart
|
||||
$ sudo chkconfig nginx on
|
||||
$ sudo chkconfig php-fpm on
|
||||
|
||||
In this example, we have configured linux-dash to use TCP port 8080. So make sure that the firewall is not blocking TCP port 8080.
|
||||
|
||||
### Monitor a Linux Machine with linux-dash ###
|
||||
|
||||
To access linux-dash from a web browser, simply go to http://<linux-IP-address>:8080/linux-dash/ on your web browser.
|
||||
|
||||
Below are the screenshots of linux-dash. The web dashboard consists of several widgets, each of which displays particular system properties. You can customize the look of the web dashboard by rearranging and/or closing some of the widgets. [Here][3] is a demo site set up by the creator of linux-dash.

How to speed read on Linux
|
||||
================================================================================
|
||||
Have you heard of speed reading? Me neither. At least not before a startup called Spritz [raised 3.5 Millions][1] in seed money to develop an API that supposedly allows a user to read 1,000 words per minute.
|
||||
|
||||
The concept of speed reading is simple: slice a text into individual short segments, like a word or two, and flash these segments very quickly. The reader's eyes do not have to move at all during the process, sparing the time we normally need to skim a page. As this technology is brand new, there is no way to tell if your brain will explode or implode above that speed. No, apparently it is [safe to use][2] as your brain is fast enough to process the information. The API should become very handy once people get accustomed to it. Now if you are as excited as I am for this, but don't want to wait or prefer to get used to it now, good news: you can already try speed reading on your favorite OS today.
|
||||
|
||||
The following are three tools that allow you to speed read on Linux.
|
||||
|
||||
### 1. Spread0r ###
|
||||
|
||||
|
||||
|
||||
Based on Perl and Gtk2, [spread0r][3] (previously called Gritz) is a GPL software that takes a text file as an input, and then flashes you the content at a speed up to 1,000 words per minute. You should however try something slower at first, just to get the hang of it. The interface is simple, nearly minimalist: launching the lecture, choosing the speed, quitting, etc. The software could use a bit of improvement. I would suggest starting by taking something else than just a text file as input (you can convert yourself though), and maybe also a “no-distract” mode? Anyway, it is still very cool.
|
||||
|
||||
You can try spread0r by downloading the sources from [github][4] and simply launching the "spread0r.pl" file. Note that you will need Gtk2 and Perl installed on your system first.
|
||||
|
||||
$ sudo apt-get install libgtk2-perl (for Debian/Ubuntu)
|
||||
$ sudo pacman -S gtk2-perl (for Archlinux)
|
||||
$ sudo yum install perl-gtk2 (for Fedora)
|
||||
|
||||
### 2. Spreed ###
|
||||
|
||||
|
||||
|
||||
Aside from ebooks and word documents, the stuff I read the most on my computer are Internet articles (yes this is meta). However, it would really be a chore if I had to copy and paste what I want to read into a text editor, save it as a txt file, and then launch it in Spread0r. Hopefully, the Chrome extension [Spreed][5] is here to cope with that. After installing and enabling Spreed on your Chrome browser, you can just select the text you want to speed read, right-click on it, and choose "Spreed selected text." It will open a new window in which the words will be flashed to you. I like the integration with Chrome, and the level of thought which was put into the extension. You can, for example, select the color set of the windows, the number of words at a time, the font size, launch the lecture and pause it via the space bar, and even go above 4,000 words per minute (that's not speed reading anymore though, it's just staring).
|
||||
|
||||
### 3. Squirt ###
|
||||
|
||||
|
||||
|
||||
If you liked the idea of speed reading from within your browser, but do not have Chrome, or do not like the idea of an extension, the solution is the bookmarklet [Squirt][6]. Despite the name which seems to come out of nowhere, Squirt is currently my favorite speed reading utility. It is efficient and easy to use. Add it from [here][7] by "drag'n'dropping" the big blue button into your favorite bar. You can then call it from any web page, after selecting some text or not, and a fancy white panel will overlay the page. You can control the lecture with intuitive shortcuts. The interface is beautiful, and it can also go above 4,000 words per minute.
|
||||
|
||||
### Bonus: Zethos ###
|
||||
|
||||
If none of the options mentioned so far pleases you, and you are a coder, then you will be happy to know that there exist a free and open source JS code called [Zethos][8] that you will be able to use in your own speed reading apps. You can check it out on [github][9], and bravo to its creator.
|
||||
|
||||
In conclusion, you have now no excuse to ignore speed reading on your favorite OS. Just try not to get your brain fried. Which one of these solutions do you prefer? Or do you have another one not mentioned here? Also do you really think that speed reading can develop in the future? Let us know in the comment.
