When the OAP server does not receive data from the agent for a long time, it is considered to be offline Does Skywalking have heartbeat detection for service instance agents? |

We have the heartbeat, but we don't measure that. Because in today's env, scaling up and down is a very common case. We usually don't need that noise. |

Our company is a bit special, and now we need this kind of notification. I want to use heartbeat to monitor the online and offline of service instances. Where should I make changes to the source code |

I don't know that. This is never in the design. You can't do that in upstream alert kernel. Maybe you could read the latest service instance in the last N minutes and compare to your known list? |

In most cases, this alerting belongs to your deployment platform, such as k8s has this status. |
