PostgreSQL SSL Integration Guide

review the following guide for setting up an integration between litmus edge and a postgresql database using ssl authentication before you begin you will need the following access to a postgresql database that uses ssl authentication the ca certificate and any other required authentication parameters to access the database refer to the following links to learn more postgresql docker image https //hub docker com/ /postgres postgresql documentation https //www postgresql org/docs/ secure tcp/ip connections with ssl https //www postgresql org/docs/16/ssl tcp html step 1 add device step 2 add tags step 3 add the db postgresql ssl connector follow the steps to add a connector docid\ ytswgweu6h6oeunhj5hw3 and select the db postgresql ssl provider configure the following parameters name enter a name for the connector hostname enter the hostname for the postgresql database port the postgresql server port the default value is 5432 ssl mode select the ssl mode (require, verify ca, verify full) ca certificate paste or upload the ca certificate associated with the database certificate paste or upload the ssl certificate private key enter or paste the ssl private key username enter the appropriate username password enter the password for the username database enter the database name table enter the table name show mapping if you want to send data to a custom table, select this check box and unselect create table see work with tables in sql connectors (create table and show mapping) docid\ ycgpmzedeewio4mes3mto to learn more to add key/value pairs for the custom table, see configure key/value pairs docid\ ycgpmzedeewio4mes3mto create table if you want to send data to an existing table in the default format, or you want to create a new table in the default format, select this checkbox and unselect show mapping see work with tables in sql connectors (create table and show mapping) docid\ ycgpmzedeewio4mes3mto to learn more commit timeout enter the transaction commit timeout in (ms) max transaction size enter the maximum number of messages before a transaction is committed, regardless of timeout parameter bulk insert count to enable this option, enter the number of messages to group together and send as one bulk insert statement enabling this option can improve how quickly data is processed when dealing with high volumes of tags throttling limit the maximum number of messages per second to be processed the default value is zero, which means that there is no limit persistent storage when enabled, this will cause messages to undergo a store and forward procedure messages will be stored within litmus edge when cloud providers are online queue mode select the queue mode as lifo (last in first out) or fifo (first in first out) selecting lifo means that the last data entry is processed first, and selecting fifo means the first data entry is processed first step 4 enable the connector after adding the connector, click the toggle in the connector tile to enable it if you see a failed status, you can review the connector logs docid\ beqq0sszwsv9v9rif3rhk and relevant error messages step 5 create topics for connector you will now need to import the tags created in step 2 as topics for the postgresql connector the topics will be created as outbound topics after adding all required topics, navigate to the integration overview page and ensure the connector is not disabled and still shows a connected status step 6 enable topics step 7 make postgresql queries you can now verify that you can view data in the postgresql database update the credentials, database name, and table name to your specific configurations to make postgresql queries from the postgresql terminal window, enter psql h locahost u postgres and press enter if you configured a different username, replace postgres the psql (9 6 5) version number appears enter \l and press enter the list of databases appears in the console enter \c postgres and press enter you are now connected to database "db example" as user "postgres" appears enter \dt and press enter the list of relations appears showing the devicehub schema enter \d devicehub and press enter the public devicehub table appears enter select from devicehub; and press enter the data for the devicehub table appears
