Hi there, I'm seeking assistance with configuring monitoring and alerts in Signoz. Here are the specific areas I need help with: 1) Alert on CrashLoopBack/OOMkilled pods & Additionally, I need assistance in configuring alerts to retrieve logs from previously terminated pods. 2) How can I establish alerts to notify when spot instances go down and are subsequently rescheduled. 3) How can I leverage Prometheus default metrics within Signoz to create alerts?"
