Add a Data Source

Configure an external database connection when Reporter needs a data source that is not already available in the Lerian Console for report generation.

Use this page to create a Data Source when Reporter needs to read from an external database or from a connection that is not already configured. If the report uses internal Lerian product data, such as Midaz or CRM, the Data Source may already exist.

Objective

---

Configure an external connection that Templates and Reports can use.

For example, create a Data Source named production-postgres that points to an external reporting database, or compliance-readonly for a read-only database user used by reporting operators.

When to use

---

Use this task when:

• the required Data Source is not already available in Reporter;
• a new database must feed reports;
• an existing report process needs a separate read-only connection;
• operators need schemas and fields available in Template Builder or report filters.

Before adding one, check whether the required internal Data Source already exists. Creating a duplicate external connection is unnecessary when Reporter already has the source configured.

Do not use this task to fix an existing connection. Use Edit a Data Source and Test a Data Source Connection.

Before you start

---

Have these details ready:

• host, port, and database name;
• username and password;
• schema names, when the database uses schemas;
• SSL requirements and CA certificate, when required by infrastructure;
• a clear connection name, such as production-postgres or compliance-readonly.

Use credentials intended for reporting access. A Data Source gives Reporter access to read data used in Templates and Reports.

Step by step

---

1. Open Data Sources

   Go to Data Sources and click Add Data Source.

2. Fill in connection details

   In Add Data Source, enter Connection Name, Database Type, Host, Port, Database Name, Username, and Password.

3. Configure schemas when needed

   For database types where the Console shows Schemas (currently PostgreSQL in the selector), add the schemas that Reporter should inspect. Type a schema name and click Add, or press Enter.

4. Configure SSL when required

   Expand SSL Configuration, turn on Enable SSL, select SSL Mode, and paste the CA Certificate if your infrastructure requires it.

5. Add metadata when useful

   Expand Metadata to add key-value fields that help operators classify the connection.

6. Create the Data Source

   Click Create.

7. Test the connection

   The new Data Source appears with Disconnected status. Run Test Connection before using it in Templates or Reports.

Field guide

---

Field	What to enter	Example
Connection Name	Required operator-facing name. Technical field: configName. Console validation: 3 to 100 characters.	production-postgres
Database Type	Required database engine. Console currently offers POSTGRESQL and MONGODB. Technical field: type.	POSTGRESQL
Host	Required database server address, not an application URL. Technical field: host.	db.example.com
Port	Required database port. Technical field: port; valid range is 1 to 65535.	5432
Database Name	Required database name Reporter will query. Technical field: databaseName.	ledger
Username	Required database user. Technical field: username.	reporter_readonly
Password	Required secret when creating a Data Source. Technical field: password.	Stored through the form
Schemas	Optional schema list for supported database types. Stored as metadata.schemas; entries are trimmed, lowercased, and deduplicated.	public, pix, transactions
Enable SSL	Optional SSL toggle. When enabled, the connection payload includes ssl.	Enabled
SSL Mode	Required when SSL is enabled. Use disable, require, verify-ca, or verify-full. Technical field: ssl.mode.	verify-ca
CA Certificate	Required for verify-ca and verify-full. Technical field: ssl.ca.	PEM CA certificate
Metadata key/value fields	Optional operator classification data. Only rows with a nonblank key are submitted. Technical field: metadata.	environment = production

Expected result

---

The new external Data Source appears on the Data Sources page with Disconnected status until tested. After a successful test, operators can use its fields in Templates and Reports.

Common errors and care points

---

Using an application URL as Host

Host should be the database server address, such as db.example.com, not the URL of an application or admin panel.

Skipping schemas

If the database uses schemas and the required schema is not listed, operators may not see the expected tables and fields.

Ignoring SSL requirements

If infrastructure requires SSL or a CA certificate, the connection can fail until SSL Configuration matches that requirement.

Using unclear names

Names like db1 are hard to use safely. Prefer names that show environment and purpose, such as production-compliance-readonly.

Next steps

---

• Use Test a Data Source Connection immediately after creation.
• Use Template Builder to use fields from the Data Source in a Template.
• Use Generate a Report after the Template and Data Source are ready.
