Yes, that's what I meant with the ALERTS metric. Have you tried it? You
can check those queries using the Prometheus UI (or API) before putting
them into alert rules.
For example, check
ALERTS{alertname="Kubepoddown_in_namespaceA",alertstate="firing"}.

My second suggestion still applies: It might be better or more
transparent if you could directly reference the relevant metrics.
However, to provide more specific guidance, we would need to know the
details of your existing two alerts.
Kind regards,
Christian
