I feel good with Xymon.

Oops. I haven’t been wrote during the New Year.
dear friend. thank you for always reading.
I might be able to entertain you too this year.

Well, in the first article.

I installed Xymon after such a long time.
I think Xymon is older than zabbix but when I use it which think simple but so comfortable though. However, it’s simple instead so it can’t do anything to complicate.

I had one problem that I’ve usually used Nginx for main contents and then I tried investigated to various information on the web.
Once before. I made set up to combination of Xymon and Nginx. in that case I was failed.
The successful method added Apache. and it was use Reverse proxy in Nginx.
Now the environment has become below for details.

Nginx Reverse Proxy ------- Nginx + Unicorn + Sinatra
                        |
                        |-- Nginx + Kibana + Elasticserach
                        |
                        |-- Apache + Xymon
                        |

I think the operation is so hassle, but it can’t be helped.

Setup was very simple.
I love simple things.

・/etc/httpd/conf/httpd.conf
 #Listen 12.34.56.78:80
-Listen 80
+Listen 8080

・/etc/nginx/conf.d/default.conf
    location ^~ /xy  {
      proxy_pass http://127.0.0.1:8080;
      proxy_redirect                          off;
      proxy_set_header Host                   $host;
      proxy_set_header X-Real-IP              $remote_addr;
      proxy_set_header X-Forwarded-Host       $host;
      proxy_set_header X-Forwarded-Server     $host;
      proxy_set_header X-Forwarded-For        $proxy_add_x_forwarded_for;
    }
