How to set the configuration in logstash to run dynamically

I am pulling the data from pgadmin and pushing to elastic search through logstash..I am using JDBC driver in Logstash but how can i update dynamically like postgres updates ..can any one suggest..E.s &L.s ,kibana Version is 6.1.2...Thankz

With LS or any other ETL you can only schedule an execution every x seconds/minutes/xxx

You can't do that in real time if this is what you meant.

Thankz a lot for your valuable information..actually i am working on report part i had choose the kibana to generate reports i am new to 'ELK'... as per my understanding after reading your reply there is no option to update dynamically in real m correct ?? ..i am facing this thing If i need last day information (data) from 'pgadmin' i need to run logstash ,this is very useless .so every morning i am keep doing this thing to get the refresh data..can u suggest me if any other options have..thankz

May be it can help.

No. If you have in your SQL table a date field like lastModified, then you can probably SELECT all records that have been modified since the last run of LS.
But that's more something to solve on the SQL database end IMO.

Thanks for such prompt reply ..i will follow your steps.

facing issue at logstash..just i need the updated data i dont know how to use schedule in my config file for a day..can i discuss here or should i start new thread..??this is my config file

stdin: db.conf
