Procedure

1. Use the following request to retrieve a list of available report templates:

   Example request:

   $ curl --insecure --user admin:redhat \
   --request GET \
   --config https://satellite.example.com/api/report_templates \
   | json_reformat

   In this example, the json_reformat tool is used to format the JSON output.

   Example response:

   {
       "total": 6,
       "subtotal": 6,
       "page": 1,
       "per_page": 20,

       "sort": {
           "by": null,
           "order": null
       },
       "results": [
           {
               "created_at": "2019-11-20 17:49:52 UTC",
               "updated_at": "2019-11-20 17:49:52 UTC",
               "name": "Applicable errata",
               "id": 112
           },
           {

           },
           {
               "created_at": "2019-11-30 16:15:24 UTC",
               "updated_at": "2019-11-30 16:15:24 UTC",
               "name": "Hosts - complete list",
               "id": 158
           },
           {
               "created_at": "2019-11-20 17:49:52 UTC",

               "updated_at": "2019-11-20 17:49:52 UTC",
               "name": "Registered hosts",
               "id": 115
           },
           {
               "created_at": "2019-11-20 17:49:52 UTC",
               "updated_at": "2019-11-20 17:49:52 UTC",
               "name": "Subscriptions",
               "id": 116

   }

2. Note the id of the template that you want to export, and use the following request to export the template:

   Example request:

   $ curl --insecure --output /tmp/_Example_Export_Template.erb_ \
   --user admin:password --request GET --config \
   https://satellite.example.com/api/report_templates/158/export

   Note that 158 is an example ID of the template to export.

   In this example, the exported template is redirected to host_complete_list.erb.

Procedure

1. In the Satellite web UI, navigate to Monitor > Report Templates, and in the upper right of the Report Templates window, click Create Template.
2. On the upper right of the Editor tab, click the folder icon, and select the .erb file that you want to import.
3. Edit the template to suit your requirements, and click Submit.

Procedure

1. Use the following example to format the template that you want to import to a .json file:

   # cat Example_Template.json
   {
       "name": "Example Template Name",
       "template": "
       Enter ERB Code Here
   "
   }

   Example JSON File with ERB Template:

   {
       "name": "Hosts - complete list",
       "template": "
   <%#
   name: Hosts - complete list
   snippet: false
   template_inputs:
   - name: host
     required: false
     input_type: user
     advanced: false
     value_type: plain
     resource_type: Katello::ActivationKey
   model: ReportTemplate
   -%>
   <% load_hosts(search: input('host')).each_record do |host| -%>
   <%
         report_row(
             'Server FQND': host.name
         )
   -%>
   <%  end -%>
   <%= report_render %>
   "
   }

2. Use the following request to import the template:

   $ curl --insecure --user admin:redhat \
   --data @Example_Template.json --header "Content-Type:application/json" \
   --request POST --config https://satellite.example.com/api/report_templates/import

3. Use the following request to retrieve a list of report templates and validate that you can view the template in Satellite:

   $ curl --insecure --user admin:redhat \
    --request GET --config https://satellite.example.com/api/report_templates | json_reformat

Procedure

1. In the Satellite web UI, navigate to Monitor > Report Templates, and click Create Template.

2. Optional: In the Editor field, use the <%# > tags to add a comment with information that might be useful for later reference. For example:

   <%#
   name: Entitlements
   snippet: false
   model: ReportTemplate
   require:
   - plugin: katello
     version: 3.14.0
   -%>

3. Add a line with the load_hosts() macro and populate the macro with the following method and variables:

   <%- load_hosts(includes: [:lifecycle_environment, :operatingsystem, :architecture, :content_view, :organization, :reported_data, :subscription_facet, :pools => [:subscription]]).each_record do |host| -%>

   To view a list of variables you can use, click the Help tab and in the Safe mode methods and variables table, find the Host::Managed row.

4. Add a line with the host.pools variable with the each method, for example:

   <%- host.pools.each do |pool| -%>

5. Add a line with the report_row() method to create a report and add the variables that you want to target as part of the report:

   <%-     report_row(
             'Name': host.name,
             'Organization': host.organization,
             'Lifecycle Environment': host.lifecycle_environment,
             'Content View': host.content_view,
             'Host Collections': host.host_collections,
             'Virtual': host.virtual,
             'Guest of Host': host.hypervisor_host,
             'OS': host.operatingsystem,
             'Arch': host.architecture,
             'Sockets': host.sockets,
             'RAM': host.ram,
             'Cores': host.cores,
             'SLA': host_sla(host),
             'Products': host_products(host),
             'Subscription Name': sub_name(pool),
             'Subscription Type': pool.type,
             'Subscription Quantity': pool.quantity,
             'Subscription SKU': sub_sku(pool),
             'Subscription Contract': pool.contract_number,
             'Subscription Account': pool.account_number,
             'Subscription Start': pool.start_date,
             'Subscription End': pool.end_date,
             'Subscription Guest': registered_through(host)
             ) -%>

6. Add end statements to the template:

   <%-   end -%>
   <%- end -%>

7. To generate a report, you must add the <%= report_render -%> macro:

   <%= report_render -%>
