在maui上运行获取当前系统信息,比如获取IP地址. windows,android,mac运行
var networks = NetworkInfo.GetRealNetworkInfos();
for (int i = 0; i < networks.Length; i++)
{
data.Add($"net_work_{i + 1}_ipv4", (networks[i].AddressIpv4.ToString()));
data.Add($"net_work_{i + 1}_ipv6", (networks[i].AddressIpv6.ToString()));
data.Add($"net_work_{i + 1}_total_up_kb", (networks[i].Ipv4Statistics.BytesSent / 1024).ToString());
data.Add($"net_work_{i + 1}_total_down_kb", (networks[i].Ipv4Statistics.BytesReceived / 1024).ToString());
InternetSpeed speed = new InternetSpeed();
networks[i].GetInternetSpeed(ref speed,1000);
data.Add($"net_work_{i + 1}_down_kb", (speed.Received.OriginSize / 1024).ToString());
data.Add($"net_work_{i + 1}_up_kb", (speed.Sent.OriginSize / 1024).ToString());
}以上代码，speed.Received.OriginSize , speed.Sent.OriginSize 皆是0，请问要怎么取？
nuget 包版本：1.0.3
不再使用函数的方式一个个调用，而是使用接口注册，统一扫描。
prometheus:v2.39.0
grafana:9.4.7 这个是版本
参考链接：metrics
支持 Prometheus，支持 grafana 。
前端api 提供json的效果
好棒的东西，给个建议把你这东西做成node exporter 实用性会更强，列出所有dotnet 进程，注入获取gc和线程数据，再加上现在的CPU 内存等，一块export出去，就通用了 ：）
最新代码好像没有找到linux下获取进程cpu、内存等指标的api
no unsupport Alpine Linux!
private MemoryMetrics GetUnixMetrics()
{
var output = "";
var info = new ProcessStartInfo("free -m");
info.FileName = "/bin/bash";
info.Arguments = "-c \"free -m\"";
info.RedirectStandardOutput = true;
using(var process = Process.Start(info))
{
output = process.StandardOutput.ReadToEnd();
Console.WriteLine(output);
}
var lines = output.Split("\n");
var memory = lines[1].Split(" ", StringSplitOptions.RemoveEmptyEntries);
var metrics = new MemoryMetrics();
metrics.Total = double.Parse(memory[1]);
metrics.Used = double.Parse(memory[2]);
metrics.Free = double.Parse(memory[3]);
return metrics;
}linux arm32v7环境下无法获取已用内存和总内存，需要的话我可以提供远程可测试的设备

出现得很频繁,基本启动10分钟就挂了
目测是这里报错了
建议添加全局异常处理, 不让程序崩掉
API 设计上，要使用监控形式，而不是提前编写好大量代码。
1.问题1：_process.Refresh(); //这里会出现阻塞
2.问题2:
` public static async Task BuildMetric(ProcessMetricsCore processMetricsCore)
{
if (ListenerPayload == null)
{
await Task.CompletedTask;
return;
}
try
{
_lock.EnterWriteLock(); //<span style="color:red;font-weight:bold">**这里会出现锁异常**</span>
await Task.Factory.StartNew(() =>
{
for (int i = 0; i < ListenerPayload.Count; ++i)
{
if (ListenerPayload[i] is IDictionary<string, object> eventPayload)
{
GetRelevantMetric(eventPayload, processMetricsCore);
}
}
});
}
catch (Exception ex) { }`
如题
支持多应用/分布式，支持主动推送

这个是偶发现象，不容易复现
