RSYSLOG for Logging HAProxy

RSYSLOG is the rocket-fast system for log processing.

It offers high-performance, great security features and a modular design. While it started as a regular syslogd, rsyslog has evolved into a kind of swiss army knife of logging, being able to accept inputs from a wide variety of sources, transform them, and output to the results to diverse destinations.

RSYSLOG can deliver over one million messages per second to local destinations when limited processing is applied (based on v7, December 2013). Even with remote destinations and more elaborate processing the performance is usually considered "stunning".

No need to install rsyslog on Linux OS because the default linux ubuntu is already installed rsyslog. The configuration file is in /etc/rsyslog.conf

Just run the rsyslog configuration for the haproxy log. Then edit the rsyslog.conf file

       nano /etc/rsyslog.conf


remove the # character as shown above. The option is useful to open port 514 with udp protocol. Then on the bottom row yourself add


local0 is configured with the global config name contained in the log haproxy config section.

. * means all events (notice, error, info) will all be logged.

- / var / log / haproxy.log is the path where the message from the log will be written into the file.

If you have server logs and want to log in to the server, just point to that log server with the settings below.



rsyslog server configuration


On the server, open port 514 with tcp protocol.


then on the bottom line add the log path.

After finished configure save the file and do not forget to restart rsyslog service

     /etc/init.d/rsyslog restart

The End. Feel free to ask any question. Thank you.

Computer Graphics Project "Planet Orbit" Source Code with Glut OpenGL

Image
Hello there !!!  This time I will post a project in the past. It is about rotation and applied to make earth orbital with moon and sun. As reminder, for you who haven’t install glut you can download it in here and follow the instruction I uploaded too. You can download this orbital project in here too. The image above is the result of orbital project. Here is the source code for this project. #include <windows.h> #include <stdlib.h> #include <GL/glut.h> #include <math.h> void myinit() { glClearColor(0.0, 0.0, 0.0, 1.0); glColor3f(1.0, 0.0, 0.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-400.0, 400.0, -400.0, 400.0,-400.0,400.0); glMatrixMode(GL_MODELVIEW); glShadeModel(GL_FLAT); glEnable(GL_DEPTH_TEST); } float putaransatu, putarandua = 0; typedef struct{ float x,y; } point2D_t; void drawDot(int x,int y){ glBegin(GL_POINTS); glVertex2i(x,y); glEnd(); } /*void bintang(void) { static int tick=0; static...

Quantization of Image Data Implementation in C#

Image
Introduction  This time we will share how to create an application to change the threshold value from black-and-white to the average value of the gray degree of all points and add textBox so that the user can change the threshold value according to the user's wishes. Besides that we also will add textBox to input quantization value. So the user can change the quantization as desired. Application Screenshoot A black-and-white image is an image that contains only black or white. Black is valued 0 and white is valued 255. To make the picture in black and white, the original color will be gray degree and each pixel will be compared with its threshold value. Normally, the black-and-white degree image has a 128 threshold value, so if the color value is less than 128, then the color is changed to 0 (black), and which is greater than or equal to 128 will be converted to 255 (white). Consider the example image below. Figure 1. The original image is predominantly dark When vi...

Computer Graphics Project "MINION" Source Code with Glut OpenGL

Hello !!! This time I post about computer graphics again. And yes, I will share a project which mainly used rotation and a little bit morphing. You can download this project here ( Download here to download glut and follow the instruction ) .The character used in this project is well known. Well here’s the depiction of this project. Minion !!! The eyes will rotate. And it’s smile will move up and down which give you a creepy smile hahaha.  So here’s the source code for this project : #include <stdio.h> #include <math.h> #include <GL/glut.h> #ifndef M_PI #define M_PI 3.141592653589793 #endif typedef struct { float x; float y; } point2D_t; typedef struct { float r; float g; float b; } color_t; ////////////// OpenGL drawShape Functions ver 1 ///////////////// void setColor(float red,float green,float blue) { glColor3f(red, green, blue); } void setColor(color_t col) { glColor3f(col.r, col.g, col.b); } void drawDot(float x,float y) { ...
