Thankyou for the response.. I think I didnt explain my question properly.. If pods in two different namespaces go down,then we need to send a alert as an appA is down.. Can I simply write expr as Kubepoddown_in_namespaceA and Kubepoddown_in_namespaceB ,and send alert message as "AppA is down"? I just wrote the pseudocode of the expr but I want to know if this expr simply works with just AND operator..
