- In your favorite text-edit application, update spec.xml to contain the column heads you need. Your updated xml file should look similar to this:
Still in your text-edit application, create a sample_data.txt file like this one that contains one or more rows of data from the feed.
- Log in to Lumeta Command Center via your browser interface.
- Navigate to Settings >Tables > Add Table.
- In the Name field, enter a descriptive name for the table you are creating such as ransomware_tracker_feed.
- In the Table Type field, select Managed Primary Table.
- At your option, you can add Tags to help other Lumeta users to find the table and a Description to let others know the purpose of the table.
- Browse to and then select the spec.xml and sample_data.txt files.
- Click Next.
The column headings for your table display, ordered alphabetically. Review the values listed in the Field column to confirm that they match your spec.xml.

- Insert the feed details into Lumeta's PostgreSQL database using the Insert command. The labels will remain the same from feed to feed. The values for each label will need to be customizer for your feed. Here's a sample entry:
insert into system.feed(name, shortname, enabled, overwrite, url, key, filename, tablename, pipelinename, pollinterval) values ('ransomware-tracker', 'ransomware', true, true, 'https://ransomwaretracker.abuse.ch', '','/feeds/csv/', 'lumeta.public.ransomware_tracker_feed', 'ransomware',1440);
- Make sure the insertion was received by entering
select * from system.feed where name ='ransomware-tracker';A response similar to this one indicates that Lumeta's database has received the insertion.
- To validate the connection, restart the lumeta-api service by entering:
support service api restartThe feed will begin to populate and records will very soon be available in the Lumeta GUI.
