[Orion]

Orion provides an easy way to create and manage custom dashboards of your Graphite data.

Key features:

Setting Up Your Environment

  1. Install and configure Apache (set the DocumentRoot, ServerRoot, Listen, etc variables appropriately)

  2. Install MySQL

  3. Install and configure PHP5 (on linux you'll want to install php5, libapache2-mod-php5)

  4. Install and enable needed PHP extensions (php5-curl, php5-mysql) a. To enable them, uncomment the lines in php.ini that mention these extensions (extension=mysql.so, extension=curl.so)

Getting Started

  1. Create the orion database (Install mysql first)-

    ./scripts/create_orion_db.sh

  2. Set ENVIRONMENT to 'development' in index.php.

  3. Setup the correct config params in config/orion.php -

For example if your metric follows the pattern

    *.*.*.*

Make the array to be like this -

$config['METRIC_CONFIG'] = array(
    array(
        "name" => "a",
        "display_order" => 0,
        "allows_wildcard" => false
    ),
    array(
        "name" => "b",
        "display_order" => 1,
        "allows_wildcard" => false
    ),
    array(
        "name" => "c",
        "display_order" => 2,
        "allows_wildcard" => false
    ),
    array(
        "name" => "d",
        "display_order" => 3,
        "allows_wildcard" => false
    )
);

The names a,b,c and d are the various levels of your metric pattern. For example the carbon metrics follow the pattern -

carbon.agents.server_name.metric_name.sub_metric_name

For this an appropriate METRIC_CONFIG would be -

$config['METRIC_CONFIG'] = array(
    array(
        "name" => "carbon",
        "display_order" => 0,
        "allows_wildcard" => false
    ),
    array(
        "name" => "agents",
        "display_order" => 1,
        "allows_wildcard" => false
    ),
    array(
        "name" => "server_name",
        "display_order" => 2,
        "allows_wildcard" => false
    ),
    array(
        "name" => "metric_name",
        "display_order" => 3,
        "allows_wildcard" => false
    ),
    array(
        "name" => "sub_metric_name",
        "display_order" => 4,
        "allows_wildcard" => false
    )
);

If there any more sub_sub_metrics then they will appear appended with the sub_metric. Therefore carbon.agents.server_name.metric_name.sub_metric_name.sub_sub_metric will also appear as a valid metric.

$config['UNWANTED_METRIC_STRINGS'] = array('carbon');

Will ignore all the metrics that have carbon as a parent.

$config['GRAPHITE_API_URL'] = 'http://graphite.wikidot.com/';
  1. IMPORTANT - Run the cache repopulate php script/view. If your orion setup is available at http://localhost/orion then the view is located at
http://localhost/orion/index.php/cache/repopulate

Warning - This view will take a long time to load if you have a large number of metrics and/or the network connection between orion server and the graphite server is slow. After it runs successfully, you should see something like this in your browser.

ADDED 1409 NEW METRICS

REMOVED 24 DEPRECATED METRICS

REPOPULATION IS COMPLETE

This script will talk with your graphite server and create a local cache of all the metrics in the mysql db. Note that this script will IGNORE ALL THE METRICS mentioned in $config['UNWANTED_METRIC_STRINGS'] variable.

The create/edit dashboard links will only parse the metrics available in the cache. If you have new metrics that you want to resync the database, just rerun this view.

  1. Determine what type of authentication you want to use. Currently supported in the default code base are Google OAuth 2.0, or a No Authentication system. Set the value of the $config['AUTHENTICATION_METHOD'] variable in config/orion.php.

If you would like to use a different method for authentication, it is possible to set this up. In order to do so, determine a short form name for you authentication method (in all capital letters). For the following examples, assume your short form name is chosen to be "NEWAUTHMETHOD".

Create a file in the helpers folder named after your short form name. For example, newauthmethod_authentication_helper.php. Make sure you include the trailing _authentication_helper.php in the file name. You will then need to define the functionality for 3 (or potentially 4) methods, and place them in this file.

function auth_get_user(){
    
    $CI =& get_instance();
    $CI->load->library('session');
    $CI->load->model('user/UserModel');

    //Parse session variables here to determine if user is logged in 
    // (for example, look for an auth token)

    $logged_in = true; //Set this variable to reflect whether the user is logged in

    if ( $logged_in ){
        //Determine the users email address
        $user_email = "myname@domain.com"; 

        $email = filter_var($user_email, FILTER_SANITIZE_EMAIL);
        $user = $CI->UserModel->authenticate($email);
    }else{
        $user = $CI->UserModel->create();
    }

    return $user;
}

function auth_logout($redirect = true){

    $CI =& get_instance();
    $CI->load->library('session');

    //Determine if the user is logged in. A good way to do so,
    // if you set a token value during login, is to grab this
    // value from the session. The value of the $token variable
    // will be false if no such variable exists in the session
    $token = $CI->session->userdata('token');
    if ($token) {

        //If the user is logged in, unset all the session variables
        $CI->session->unset_userdata('token');
        $CI->session->unset_userdata('name');
        $CI->session->unset_userdata('user');
    }

    //Do not change this
    if ($redirect){
        redirect('orion');
    }else{
        return;
    }
}

function auth_login($input){
    //The input variable is an array of parameters passed to the login
    // script via the GET method.
    // If using an external authentication method that allows the hand off
    // of state variables, you can use the $input['location'] variable to
    // pass the desired location of the user through the authentication
    // method, and redirect the user to this location upon logging in
    
    $CI =& get_instance();

    //This is where you do your work to log the user in
    
    //If you need to go to an external source, you will likely
    // need a callback function. For this, see below.
}

function auth_callback($input){
    //This is only used if you need to go to an external source for
    // authentication purposes

    //The input variable is an array of parameters passed to the login
    // script via the GET method.    

    //If you need to provide a callback URL to the external source,
    // assuming your base instance is 'http://localhost/orion/', your 
    // authentication callback will be 
    // 'http://localhost/orion/index.php/authenticate/authenticate_callback/'
    
    $CI =& get_instance();
    $CI->load->library('session');
    $CI->load->model('user/UserModel');

    //This is where you do your work, given the information from the external
    // source to log the user in

    $external_auth_success = true; //Set this variable to reflect whether the user was logged in by the external source

    if ( $external_auth_success ){
        //Though not necessary, the following few lines are recommended
        // If you have a token, it is wise to save the token in the session
        // Similarly, if you know the user's name, you can save it in the
        // session, and the UI will reflect this when the user is logged in
        $CI->session->set_userdata(array('token' => $token));
        $CI->session->set_userdata(array('name' => $user_real_name));

        //These are necessary lines. You must in some way or another, set these
        // values. First, you determine the user's email, and authenticate them
        // (which will create a new user if not present in the DB). This will
        // return the authenticated user. You need to save this user as a json
        // encoded object in the session under the key 'user'. This is already
        // done in the lines below, all you need to do is set the $user_email variable 
        $email = filter_var($user_email, FILTER_SANITIZE_EMAIL);
        $user = $CI->UserModel->authenticate($email);
        $CI->session->set_userdata(array('user' => json_encode($user)));

        //If you used the location value in the auth_login function, and passed this
        // through the external authentication source, you can use the following lines
        // to redirect to the new location.
        $redirect = $external_source_value; //Set the $redirect variable to reflect whether the value passed back by the external source
        if (!$redirect){
            $redirect = "orion";
        }
        redirect($redirect);

    }

    redirect('orion');
}

After creating this file and defining the functionality for these methods, change the value of the $config['AUTHENTICATION_METHOD'] variable to what you chose as your short form name (in this example it was "NEWAUTHMETHOD"). It should look like this

$config['AUTHENTICATION_METHOD'] = 'NEWAUTHMETHOD';

Test your new authentication method.
