I don't think it's a false alert. If it's the rule you showed, then the only way you can get an alert is if the metric probe_success has value zero. You should try to understand *why* BBE is returning zero; if necessary use tcpdump or wireshark to capture the HTTP traffic to and from it.
But you also need to resolve the issue with BBE panicking - does it log a backtrace when it does this? If so, showing the backtrace could help identify what's going on. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
