我在本地 Windows 机器上使用 Java VisualVM 来监控我的远程服务器(Linux)。我能够在 Bisual VM 中获得除“ Visual GC ”之外的所有统计信息。它显示“不支持此 JVM”。我用谷歌搜索了一下,发现可能是因为 jstatd 没有运行和连接。所以执行“ jstatd -J-Djava.security.policy=/tmp/tools.policy ”。它显示了一个 IP“ 175.41.139.225 ”。我不明白为什么它试图连接到这个 ip。它不是我的远程机器的 ip,也不是我的本地机器的 ip。
[root@shipping_pt mail]# jstatd -J-Djava.security.policy=/tmp/tools.policy
