http://www.percona.com/doc/percona-monitoring-plugins/cacti/mongodb-templates.html

Once the SSH connection is working, confirm that you can login to MongoDB from with the “mongo” cli tool. From this tool, confirm that the serverStatus command is present by running:

db._adminCommand({serverStatus : 1});

This should produce quite a bit of output. With all of this confirmed, test one of your hosts with the command below. You may need to change some of the example values below, such as the cacti username and the hostname you’re connecting to:

su - cacti -c 'env -i php /var/www/cacti/scripts/ss_get_by_ssh.php --type mongodb --host 127.0.0.1 --items jc,jd'

Setup Nginx graph:

sudo passenger-install-nginx-module

select 2. No: I want to customize my Nginx installation. (for advanced users)

Where is your Nginx source code located?

Please specify the directory: /tmp/nginx-1.2.3

Extra Nginx configure options

If you want to pass extra arguments to the Nginx 'configure' script, then
please specify them. If not, then specify nothing and press Enter.

If you specify nothing then the 'configure' script will be run as follows:

sh ./configure --prefix='/opt/nginx' --with-http_ssl_module --with-http_gzip_static_module --with-cc-opt='-Wno-error' --with-pcre='/tmp/root-passenger-15137/pcre-8.30' --add-module='/usr/lib64/ruby/gems/1.8/gems/passenger-3.0.15/ext/nginx'

Extra arguments to pass to configure script: --with-http_stub_status_module

--------------------------------------------

Confirm configure flags

The Nginx configure script will be run as follows:

sh ./configure --prefix='/opt/nginx' --with-http_ssl_module --with-http_gzip_static_module --with-cc-opt='-Wno-error' --with-pcre='/tmp/root-passenger-15137/pcre-8.30' --add-module='/usr/lib64/ruby/gems/1.8/gems/passenger-3.0.15/ext/nginx' --with-http_stub_status_module

Is this what you want? (yes/no) [default=yes]: yes
