VMAnalyzer:基于虚拟化技术的性能监控分析工具项目

安装指南

0. 确保 Redis 服务器正在运行

# redis-server &

若redis已启动，但步骤2无法执行，请kill后重启服务

1. 查看帮助

# vm-analyzer-agent --help

usage: vm-analyzer-agent [-hdi] [uri]
   uri will default to qemu:///system
   --help, -h   Print this help message
   --debug, -d  Print debug output
   --interval=SECS, -i  Configure statistics collection interval
   --timeout=SECS, -t  Quit after SECS seconds running
   --memoryUsage, -m  Print detected memory usage

2. 执行 vm-analyzer-agent 流程

# vm-analyzer-agent

默认策略为采集CPU利用率周期为1秒，10秒上报一次，CPU利用率显示如下：

...
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "13.00%", "TimeStamp": 1598015380}}
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "14.00%", "TimeStamp": 1598015381}}
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "15.00%", "TimeStamp": 1598015382}}
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "16.00%", "TimeStamp": 1598015383}}
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "17.00%", "TimeStamp": 1598015384}}
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "18.00%", "TimeStamp": 1598015385}}
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "19.00%", "TimeStamp": 1598015386}}
{"6717da86-fc51-474d-92fe-a76380c27c62": {"Current_cpu_utilization": "20.00%", "TimeStamp": 1598015387}}
...

3. 或者开启调试（debug）模式：

# vm-analyzer-agent -d

4. 启用内存利用率检测策略：

前提： 支持ballon

# vm-analyzer-agent -m

{"qh-bc8.4": {"Current_mem_utilization": 100.0, "TimeStamp": 1715050794}}
{"qh-bc8.4": {"Current_mem_utilization": 100.0, "TimeStamp": 1715050795}}
{"qh-bc8.4": {"Current_mem_utilization": 100.0, "TimeStamp": 1715050796}}
{"xz-bc8.4": {"Current_mem_utilization": 47.8928, "TimeStamp": 1715050789}}
{"xz-bc8.4": {"Current_mem_utilization": 47.6398, "TimeStamp": 1715050790}}
{"xz-bc8.4": {"Current_mem_utilization": 47.3871, "TimeStamp": 1715050791}}
{"xz-bc8.4": {"Current_mem_utilization": 47.1347, "TimeStamp": 1715050792}}

5. 启用网络流量检测策略：

# vm-analyzer-agent -n

{"qh-bc8.4": {"interfaceAddresses": {"vnet1": "52:88:99:34:fa:3a"}, "networkTraffic": {"vnet1": {"rx_bytes": 337411141, "rx_packets": 490359, "rx_errs": 0, "rx_drop": 0, "tx_bytes": 181581140, "tx_packets": 78410, "tx_errs": 0, "tx_drop": 0}}, "TimeStamp": 1715222742}}

{"xz-bc8.4": {"interfaceAddresses": {"vnet9": "52:54:00:78:2f:1c", "vnet10": "52:54:00:9b:00:cf"}, "networkTraffic": {"vnet9": {"rx_bytes": 4818498, "rx_packets": 88505, "rx_errs": 0, "rx_drop": 0, "tx_bytes": 335078, "tx_packets": 2350, "tx_errs": 0, "tx_drop": 0}, "vnet10": {"rx_bytes": 4322460, "rx_packets": 80364, "rx_errs": 0, "rx_drop": 0, "tx_bytes": 440782, "tx_packets": 2431, "tx_errs": 0, "tx_drop": 0}}, "TimeStamp": 1715222735}}

interfaceAddresses: 云主机网卡设备MACaddress信息
networkTraffic： 云主机网卡设备网络流量信息

6. 开启磁盘 I/O 检测策略：

# vm-analyzer-agent -b

{"qh-win2019": {"blkStatus": {"vda": {"capacity": 32212254720, "allocation": 19854467072, "physical": 19854458880}}, "blkI/O": {"vda": {"read_bytes": 646335, "read_requests": 13906328064, "write_bytes": 246490, "write_requests": 2919450624, "errors": -1}}, "TimeStamp": 1715658674}}
{"dlm-bc8.4": {"blkStatus": {"sdb": {"capacity": 10737418240, "allocation": 1443700736, "physical": 1443561472}}, "blkI/O": {"sdb": {"read_bytes": 10135, "read_requests": 206083072, "write_bytes": 277321, "write_requests": 1835865088, "errors": -1}}, "TimeStamp": 1715658667}}

blkStatus: 磁盘信息
blkI/O： 磁盘I/O信息

7. 启用虚拟机日志检测策略：

# vm-analyzer-agent --log_vm
