之前有一篇博客介绍如何获取Linux服务器上的资源使用情况《Java 获取服务器资源内存、负载、磁盘容量》这里介绍如何通过C#获取Window系统的资源使用。
2.获取服务器资源
2.1.内存
[DllImport(kernel32.dll)][return: MarshalAs(UnmanagedType.Bool)]private static extern bool GlobalMemoryStatusEx(ref MEMORY_INFO mi);//定义内存的信息结构[StructLayout(LayoutKind.Sequential)]private struct MEMORY_INFO {public uint DWLength;//当前结构体大小public uint DWMemoryLoad;//当前内存使用率public ulong ullTotalPhys;//总计物理内存大小public ulong ullAvailPhys;//可用物理内存代销public ulong ullTotalPagefiles;//总计交换文件大小public ulong ullAvailPagefiles;//可用交换文件大小public ulong ullTotalVirtual;//总计虚拟内存大小public ulong ullAvailVirtual;//可用虚拟内存大小}private static MEMORY_INFO GetMemoryInfo() {MEMORY_INFO memoryInfo new MEMORY_INFO();memoryInfo.DWLength (uint)System.Runtime.InteropServices.Marshal.SizeOf(memoryInfo);GlobalMemoryStatusEx(ref memoryInfo);return memoryInfo;}/// summary/// 获取内存信息/// /summary/// returns/returnspublic static ServerMemory GetSysMemoryInfo(){try{MEMORY_INFO memoryInfo GetMemoryInfo();ServerMemory serverMemory new ServerMemory();serverMemory.serverId serverId;serverMemory.serverName serverName;serverMemory.memTotal (uint)(memoryInfo.ullTotalPhys / 1024);serverMemory.memFree (uint)(memoryInfo.ullTotalPagefiles / 1024);serverMemory.memAvailable (uint)(memoryInfo.ullAvailPhys / 1024);serverMemory.active (uint)(memoryInfo.ullAvailPhys/1024);long timestamp CommonUtil.getNowDateTimestamp();serverMemory.dateTimestamp timestamp;serverMemory.dateTime CommonUtil.dateTime2Timestamp(timestamp);return serverMemory;}catch (Exception ex) {Log.Instance.Error(GetSysMemoryInfo: ex.Message);return null;}}
因为获取到的资源是以byte为单位我这里将其转成了KB所以除以了1024.
ServerMemory实体类
public class ServerMemory{public string serverId { set; get; }public string serverName { set; get; }/// summary/// 内存总量/// /summarypublic uint memTotal { set; get; }/// summary/// 系统保留量/// /summarypublic uint memFree { set; get; }/// summary/// 应用程序可用量/// /summarypublic uint memAvailable { set; get; }/// summary/// 可使用量/// /summarypublic uint active { set; get; }public string dateTime { set; get; }public long dateTimestamp { set; get; }}
2.2.磁盘
public static ServerDisk GetUsedDisk() {try{ListDictionarystring, string diskInfoList new ListDictionarystring, string();ManagementClass diskClass new ManagementClass(Win32_LogicalDisk);ManagementObjectCollection disks diskClass.GetInstances();foreach (ManagementObject disk in disks){Dictionarystring, string diskInfoDic new Dictionarystring, string();try{// 磁盘名称diskInfoDic[Name] disk[Name].ToString();// 磁盘描述diskInfoDic[Description] disk[Description].ToString();// 磁盘总容量可用空间已用空间if (System.Convert.ToInt64(disk[Size]) 0){long totalSpace System.Convert.ToInt64(disk[Size]) / 1024;long freeSpace System.Convert.ToInt64(disk[FreeSpace]) / 1024;long usedSpace totalSpace - freeSpace;diskInfoDic[totalSpace] totalSpace.ToString();diskInfoDic[usedSpace] usedSpace.ToString();diskInfoDic[freeSpace] freeSpace.ToString();}diskInfoList.Add(diskInfoDic);}catch (Exception ex){Log.Instance.Error(ManagementObject-disk: ex.Message);}}if (diskInfoList.Count 0){ServerDisk serverDisk new ServerDisk();serverDisk.serverId serverId;serverDisk.serverName serverName;Dictionarystring, DiskInfo diskMap new Dictionarystring, DiskInfo();foreach (Dictionarystring, string dic in diskInfoList){if (dic.ContainsKey(totalSpace) dic.ContainsKey(usedSpace) dic.ContainsKey(freeSpace)){DiskInfo diskInfo new DiskInfo();diskInfo.diskName dic[Name];diskInfo.diskSize double.Parse(dic[totalSpace]);diskInfo.used double.Parse(dic[usedSpace]);diskInfo.avail double.Parse(dic[freeSpace]);diskInfo.usageRate (int)((diskInfo.used / diskInfo.diskSize) * 100);diskMap.Add(diskInfo.diskName, diskInfo);}}serverDisk.diskInfoMap diskMap;long timestamp CommonUtil.getNowDateTimestamp();serverDisk.dateTimestamp timestamp;serverDisk.dateTime CommonUtil.dateTime2Timestamp(timestamp);return serverDisk;}else{return null;}}catch (Exception ex) {Log.Instance.Error(GetUsedDisk:ex.Message);return null;}}
ServerDisk实体类 public class ServerDisk{public string serverId { set; get; }public string serverName { set; get; }public Dictionarystring,DiskInfo diskInfoMap { set; get; }public string dateTime { set; get; }public long dateTimestamp { set; get; }}
DiskInfo实体类 public class DiskInfo{public string diskName { set; get; }public double diskSize { set; get; }public double used { set; get; }public double avail { set; get; }public int usageRate { set; get; }}
2.3.CPU
public static ServerCpu GetUsedCPU() {ManagementClass mc new ManagementClass(Win32_PerfFormattedData_PerfOs_Processor);ManagementObjectCollection moc mc.GetInstances();List string list new List string ();foreach (ManagementObject mo in moc) {if (mo[Name].ToString() _Total) {list.Add(mo[percentprocessorTime].ToString());}}int percentage list.Sum(s int.Parse(s));ServerCpu serverCpu new ServerCpu();serverCpu.serverId serverId;serverCpu.serverName serverName;serverCpu.percentage percentage;long timestamp CommonUtil.getNowDateTimestamp();serverCpu.dateTimestamp timestamp;serverCpu.dateTime CommonUtil.dateTime2Timestamp(timestamp);return serverCpu;}
ServerCpu实体类 public class ServerCpu{public string serverId { set; get; }public string serverName { set; get; }public int percentage { set; get; }public string dateTime { set; get; }public long dateTimestamp { set; get; }}
3.最终效果
最终我想实现对Linux和Windows服务器的监控类似效果如下
