我们在Red Hat Enterprise Linux Server 7.7上使用Apache Artemis 2.14.0版本(Linux 3.10.0-1062.el7.x86_64 x86_64(。但服务器启动失败给出：
AMQ201001: Network is unhealthy, stopping service ActiveMQServerImpl
我们已经配置了ping命令，并且ping返回成功，没有任何明显的延迟。
Ping输出
ping 10.30.12.21
PING 10.30.12.21 (10.30.12.21) 56(84) bytes of data.
64 bytes from 10.30.12.21: icmp_seq=1 ttl=63 time=0.337 ms
64 bytes from 10.30.12.21: icmp_seq=2 ttl=63 time=0.380 ms
Ping配置
<network-check-period>5000</network-check-period>
<network-check-timeout>1000</network-check-timeout>
<network-check-list>10.30.12.21,10.30.12.22</network-check-list>
<network-check-ping-command>ping -c 1 -t %d %s</network-check-ping-command>
两个ping ip都可以毫无问题地访问。如果我评论ping配置服务器良好。

我怀疑您使用的ping命令(即ping -c 1 -t %d %s(实际上对您的操作系统或用例无效。要确认这一点，您需要为org.apache.activemq.artemis.core.server.NetworkHealthCheck激活TRACE日志记录，重现问题，然后检查日志。有关如何为特定记录器启用TRACE日志记录的详细信息，请参阅此问题。
一旦你有了日志，就很容易看出实际的问题是什么。之后，你可以根据用例的需要调整ping命令。
