Beta Branch Centmin Mod Nginx live vhost traffic statistics preview & discussion

Dedicated discussion thread for Nginx Vhost Traffic Statistics module that I plan to add to Centmin Mod .08 beta.

How Nginx Vhost Traffic Stats Module Integrates into Centmin Mod Nginx

Module: https://github.com/vozlt/nginx-module-vts

On nginx upgrades within .08 beta which has nginx vhost traffic stats module added, you will get 3 new include files for nginx.conf, vhost.conf and your individual nginx vhost domain.com.conf files. On upgrades only nginx.conf and vhost.conf get the new include files automatically populated for existing files. The 3rd include file for nginx vhost domain.com.conf will need manually adding for existing installs (for new fresh installs, they are added automatically during centmin.sh menu option 2 add vhost stage).

in nginx.conf

Code:

http {
include /usr/local/nginx/conf/vts_http.conf;

contents = Sets parameters for a shared memory zone that will keep states for various keys. The cache is shared between all worker processes

Code:

vhost_traffic_status_zone;

in vhost.conf

Code:

include /usr/local/nginx/conf/vts_mainserver.conf;

contents = ip restricted by default enables vhost_traffic_status = on or off for each individual nginx vhost and display in html format (other option is in json format) to be displayed at yourmainhostname/vhost_status or yourmainhostname/vhost_status.html

Code:

location /vhost_status {
    allow 127.0.0.1;
    #allow YOURIPADDRESS;
    deny all;
    vhost_traffic_status on;
    vhost_traffic_status_display;
    vhost_traffic_status_display_format html;
}

location = /vhost_status.html {
    allow 127.0.0.1;
    #allow YOURIPADDRESS;
    deny all;
}

for individual nginx domain.com.conf vhosts will need to add this manually for existing servers that upgrade (for new fresh installs, already added)

Code:

include /usr/local/nginx/conf/vts_server.conf;

contents = enables vhost_traffic_status = on or off for each individual nginx vhost to be displayed at yourmainhostname/vhost_status

Code:

            vhost_traffic_status on;

local virtualbox testing with bit of siege benchmarking

at yourmainhostname/vhost_status



or yourmainhostname/vhost_status.html for custom CSS colour version

Centmin Mod 123.08beta03 is now available - 123.08beta03 branch is the merging of the 3 branches - .08 beta 02 + 123.08lua + 123.08livestats so the new beta has both Nginx Lua + LuaJIT support + new Nginx vhost traffic statistics

feedback for Nginx vhost traffic stats related stuff can be posted in this thread

 

If you do not have a static IP address and can not use IP restriction in, then you'll need to password protect that directory

Step 1. create htpasswd file /usr/local/nginx/conf/vts_htpasswd with user and password of your choosing with below command where USERNAME and PASSWORD are of your own choosing.via the custom password generator at /usr/local/nginx/conf/htpasswd.sh

If you're backing up your nginx vhosts maybe better to place /usr/local/nginx/conf/vts_htpasswd file at something like /home/nginx/domains/yourdomain.com/private/vts_htpasswd

At /usr/local/nginx/conf/vts_htpasswd type in SSH window the command below

Code:

/usr/local/nginx/conf/htpasswd.sh create /usr/local/nginx/conf/vts_htpasswd USERNAME PASSWORD

or

At /home/nginx/domains/yourdomain.com/private/vts_htpasswd replacing yourdomain.com with your domain type in SSH window the command below

Code:

/usr/local/nginx/conf/htpasswd.sh create /home/nginx/domains/yourdomain.com/private/vts_htpasswd USERNAME PASSWORD

Step 2. edit /usr/local/nginx/conf/vts_mainserver.conf

Then contents of /usr/local/nginx/conf/vts_mainserver.conf becomes

Code:

        location /vhost_status {
            auth_basic "Private";
            auth_basic_user_file /usr/local/nginx/conf/vts_htpasswd;
            vhost_traffic_status on;
            vhost_traffic_status_display;
            vhost_traffic_status_display_format html;
        }

       location = /vhost_status.html {
            auth_basic "Private";
            auth_basic_user_file /usr/local/nginx/conf/vts_htpasswd;
            allow 127.0.0.1;
           #allow YOURIPADDRESS;
          deny all;
      }

or

Code:

        location /vhost_status {
            auth_basic "Private";
            auth_basic_user_file  /home/nginx/domains/yourdomain.com/private/vts_htpasswd;
            vhost_traffic_status on;
            vhost_traffic_status_display;
            vhost_traffic_status_display_format html;
        }

       location = /vhost_status.html {
            auth_basic "Private";
            auth_basic_user_file  /home/nginx/domains/yourdomain.com/private/vts_htpasswd;
            allow 127.0.0.1;
           #allow YOURIPADDRESS;
          deny all;
      }

Step 3. restart Nginx and PHP services via command shortcut

Code:

nprestart

 

thanks @vozlt for the info and awesome add on you wrote - assuming you're author vozlt/nginx-module-vts · GitHub

 

@vozlt I tried customising the CSS colours for html display mode Customising html template ? · Issue #13 · vozlt/nginx-module-vts · GitHub but even after recompiling nginx, the new colours don't turn up ?

 

Thanks seems path to fileToHex.pl is relative as tried but can't find fileToHex.pl

Code:

util/tplToDefine.sh share/status.template.html > src/ngx_http_vhost_traffic_status_module_html.h
Can't open perl script "fileToHex.pl": No such file or directory

but fine with running it within util directory

Code:

./tplToDefine.sh ../share/status.template.html > ../src/ngx_http_vhost_traffic_status_module_html.h

more verbose look

Code:

bash -x tplToDefine.sh ../share/status.template.html > ../src/ngx_http_vhost_traffic_status_module_html.h
+ PATH=/sbin:/usr/sbin:/bin:/usr/bin
+ export PATH
+ template=../share/status.template.html
+ '[' -z ../share/status.template.html ']'
++ date +%s
+ tmp=../share/status.template.html.1433144033
+ cp -af ../share/status.template.html ../share/status.template.html.1433144033
+ '[' -f ../share/status.template.html.1433144033 ']'
+ perl -p -i -e s/%/%%/g ../share/status.template.html.1433144033
+ perl -p -i -e 's/{{uri}}/%V/g' ../share/status.template.html.1433144033
+ echo '#define NGX_HTTP_VHOST_TRAFFIC_STATUS_HTML_DATA \'
+ perl fileToHex.pl ../share/status.template.html.1433144033
+ rm -f ../share/status.template.html.1433144033

Tried the before install method but sill old colors show up after nginx recompile - is it because i use url vhost_status and not status for url ?

just changing the CSS in share/status.template.html

Code:

        <style>
            body {
                background:  white;
                font-family: Helvetica, Arial, sans-serif;
            }

            h1 {
                margin: .5em 0 0 0;
            }

            h2 {
                margin: .8em 0 .3em 0;
            }

            h3 {
                margin: .5em 0 .3em 0;
            }

            table {
                font-size: .8em;
                margin: .5em 0;
                border-collapse: collapse;
                border-bottom: 1px #43a6df solid;
            }

            thead th {
                font-size: 1em;
                background: #43a6df;
                padding: .1em .3em;
                border: .2em solid #FFF;
            }

            tbody tr.odd {
                background: #F5F5F5;
            }

            tbody th {
                text-align: left;
            }

            tbody td {
                height: 1.2em;
                text-align: right;
            }

            tbody td.key {
                font-size: 1em;
                background: #43a6df;
                padding: .1em .3em;
                border: .2em solid #FFF;
            }
        </style>

while before install doesn't work, after install works

I believe it should as all I am doing is sed replace on the status.template.html file

Code:

cd /svr-setup/nginx-module-vts
sed -i 's|#DED|#43a6df|g' /svr-setup/nginx-module-vts/share/status.template.html
sed -i 's|#DED|#43a6df|g' /svr-setup/nginx-module-vts/share/status.compress.html
cd util
./tplToDefine.sh ../share/status.template.html > ../src/ngx_http_vhost_traffic_status_module_html.h

then recompile nginx with --add-module=../nginx-module-vts

FYI on the /vhost_status page which still shows the old #DED colours, it's pulling the compressed html status template in source code still if that helps. So i tried this too but doesn't work either

Code:

./tplToDefine.sh ../share/status.compress.html > ../src/ngx_http_vhost_traffic_status_module_html.h

still shows old #DED colours

for working after install, i just copy /svr-setup/nginx-module-vts/share/status.template.html to /status.html and that works

 

thanks @vozlt for explanation oh for code you can wrap it in [CODE][/CODE] tags too on the forums

Guess it would be harder to do this way if I am automating this in an installer as I would have to know the uri that the end user uses for their Centmin Mod Nginx install before hand. I suppose I could try it from the default main host name's nginx vhost.conf file - but would also need to know their url/path if they decide to use something other than /status or /status.html i.e. /vhost_status or /vhost_status.html

Code:

awk -F " " '/server_name/ {print $2}' /usr/local/nginx/conf/conf.d/virtual.conf | sed 's|;||'
mainhostname.domain.com

then replace {{uri}} with that mainhostname.domain.com/vhost_status

But i guess if i set it to /vhost_status or /vhost_status.html not many folks will change it later

 

Okay did it the method @vozlt outlined with custom vhost_status.html template at /usr/local/nginx/html/vhost_status.html

changed include file at /usr/local/nginx/conf/vts_mainserver.conf to

Code:

location /vhost_status {
    allow 127.0.0.1;
    #allow YOURIPADDRESS;
    deny all;
    vhost_traffic_status on;
    vhost_traffic_status_display;
    vhost_traffic_status_display_format html;
}

location = /vhost_status.html {
    allow 127.0.0.1;
    #allow YOURIPADDRESS;
    deny all;
}

Wordpress 7 site is first site to switch to .08 beta03's latest Nginx configuration and working vhost traffic stats

 

is that during install or at end of install and you try nginx restart ?

at end of install, if you do nginx restart any errors ? that's all that matters if at end of install and nginx restart has no errors

 

okay seems i forgot the map checks on initial nginx install... added the checks now update inc/nginx_install.inc initial nginx install routine · centminmod/centminmod@af3ed08 · GitHub
