               var textValue1 = $text1   "\n"
               cy.log(textValue1)
               var  total = parseInt(textValue1)
               sum  = total
            })
        }
        cy.log("Total of all connected OS= "   sum)
    }

In the cypress automation, when I'm running this block of code it is returning the sum=0 but I don't know why it is displaying 0. Please help me out.

Cypress behaves weirdly when running inside of a for loop. When Cypress commands are executed vs. just regular JavaScript is not readily apparent without really diving into the inner workings of Cypress. A more reliable way to get Cypress to behave as expected would be to use Cypress Lodash (it is essentially a Cypress wrapper around Lodash).

let sum = 0
Cypress._.times(6, (i) => {
  // lodash times gives us the index of the current iteration as the parameter in the callback
  // this can be used the same as the `i` in your for loop.
  // code to execute
});

Cypress commands are asynchronous. cy.log captures the sum value before the first xpath command gets really executed. To synchronize access to the sum you can use a then callback:

verifyActiveInterfacesViaConnectionStatus() {
        var sum = 0
        var i;
        for (i = 1; i <= 5; i  ) {
            cy.xpath(`(//*[name()='g' and @class ='highcharts-label highcharts-data-label highcharts-data-label-color-undefined']//*[name()='text']//*[@class='highcharts-text-outline'])[${i}]`).invoke("text").then(($text1) => {

               var textValue1 = $text1   "\n"
               cy.log(textValue1)
               var  total = parseInt(textValue1)
               sum  = total
            })
        }
        cy.then(() => {
           cy.log("Total of all connected OS= "   sum)
        })
    }
