Reading custom data sources error Messages

Hi please find the below code

import groovy.sql.Sql
import java.sql.SQLException

// Register the Sybase driver
Class.forName("com.sybase.jdbc4.jdbc.SybDriver")

// Get basic info to connect
def hostname = hostProps.get("system.hostname")
def user = hostProps.get("sybase.user")
def pass = hostProps.get("sybase.pass")
def port = 21000
def wildvalue = instanceProps.get("wildvalue")
def url = "jdbc:sybase:Tds:" + hostname + ":21000"
def driver = "com.sybase.jdbc4.jdbc.SybDriver"

def sql = Sql.newInstance(url, user, pass, driver)

// Check Sybase server status
try {
sql.getConnection()
println("status:0") // Server is online
} catch (SQLException e) {
if (e.getMessage().contains("Login failed")) {
println("status:1") // Invalid password or login failed
} else {
println("status:2") // Other connection or server error, including server offline
}
} finally {
sql.close()
}

    Please insert code blocks using the code block option in the toolbar.

    You should be setting the return code in a variable in your try/catch/finally block and returning that error code. Then you can just have a datapoint that looks at the return code. That also solves the problem of your current code not having a return code, which will cause LM to ignore the output.

    return_code = 0
    try {
        sql.getConnection()
    } catch (SQLException e) {
        if (e.getMessage().contains("Login failed")) {
            return_code = 1 // Invalid password or login failed
        } else {
            return_code = 2 // Other connection or server error, including server offline
        }
    } finally {
        sql.close()
        return return_code
    }

    No need for a print statement unless you have something other than the return code you want to return.

    The toolbar is right above the text you’re typing. It has bold, italic, underline, etc. On the right, there are three dots and that has a code widget you can insert.

    The only thing I can guess is that when groovy tries the sql.getConnection(), it’s resolving to true even if login fails. You’ll need to figure out something additional that determines if login was successful or not.
