Status pages

The portal displays in JSON format its activity. Some d This can give a view to all returned codes.

* Set portalStatus = 1 in lemonldap-ng.ini file (section [Portal]) * Note that handler status must also been enabled * Protect http://portal/portalStatus using your webserver configuration

Status is displayed by calling this URL.

When status feature is activated, Handlers and portal will collect statistics and save them in their local cache. This means that if several Handlers are deployed, each will manage its own statistics.

The statistics are collected trough a daemon launched by the Handler. It can be seen in system processes.

Statistics are displayed when calling the status path on an Handler (for example: http://reload.example.com/status).

Example of status page:

You need to give access to status path in the Handler Nginx configuration:

server {
  listen __PORT__;
  server_name reload.__DNSDOMAIN__;
  root /var/www/html;
  ...
  location = /status {
    allow 127.0.0.1;
    deny all;
    include /etc/nginx/fastcgi_params;
    fastcgi_pass unix:__FASTCGISOCKDIR__/llng-fastcgi.sock;
    fastcgi_param LLTYPE status;
  }
}

You need to give access to status path in the Handler Apache configuration:

    # Uncomment this to activate status module
    <Location /status>
        Order deny,allow
        Allow from 127.0.0.0/8
        PerlHeaderParserHandler Lemonldap::NG::Handler->status
    </Location>

Then restart Apache.

By default Apache handler status process listen to localhost:64321 (UDP). You can change this using LLNGSTATUSLISTEN environment variable. If you want to collect portal data, you just have to set LLNGSTATUSHOST environment variable (see comments in our portal-apache2.conf).

  <Files *.fcgi>
    SetHandler fcgid-script
    # For Authorization header to be passed, please uncomment one of the following:
    # for Apache >= 2.4.13
    #CGIPassAuth On
    # for Apache < 2.4.13
    #RewriteCond %{HTTP:Authorization} ^(.*)
    #RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]
    Options +ExecCGI
    header unset Lm-Remote-User
  </Files>
  FcgidInitialEnv LLNGSTATUSHOST 127.0.0.1:64321

Edit lemonldap-ng.ini, and activate status in the handler section:

[all]
# Set status to 1 if you want to have the report of activity (used for
# example to inform MRTG)
status = 1

Then restart webserver.

1. You can also open the UDP port with Nginx if you set LLNGSTATUSLISTEN environment variable (host:port)
2. When querying status (using portal or handler status) and if UDP is used, query is given to LLNGSTATUSHOST (host:port) and response is waiting on a dynamic UDP port given in query (between 64322 and 64331). By default this dynamic UDP port is opened on loopback (localhost entry in /etc/hosts). To change this, set an IP address or a host using LLNGSTATUSCLIENT environment variable.
