Properties File을 이용한 Logback 설정


카테고리 없음 2018. 7. 11. 14:25

응용 시스템에서 로그를 남기기 위해 Logback을 사용하는 경우 Properties를 별도의 파일로 분리하여 설정이 가능하다.


■ logback.properties


#######################################################

# Logback propertiies                                  #

#######################################################

log.dir=d:/temp/logs/batchagent

log.level=DEBUG

app.log.name=agent_app

err.log.name=agent_error

max.history=7

max.log.file.size=50MB


Properties 파일은 key=value로 정의하면 된다.



■ logback.xml

logback.xml 파일에 properties 파일을 <property file="" />를 이용하여 Properties 파일을 읽는다.


Properties 파일에 정의되어 있는 Property를 사용할 때 ${property key}로 사용하면 된다.

Java를 이용한 서버 CPU, 메모리 자원 모니터링


카테고리 없음 2018. 7. 6. 15:16

Java를 이용하여 시스템에 대한 CPU, 메모리의 정보를 받아오기 위해서 sigar Library를 이용하면 쉽고 정확하게 원하는 정보를 추출할 수 있다.


sigar는 scouter APM 툴에서 서버의 자원을 모니터링하기 위해서 사용하고 있다.


■ 소스 예제


import java.util.HashMap;

import java.util.Map;


import org.hyperic.sigar.CpuPerc;

import org.hyperic.sigar.DirStat;

import org.hyperic.sigar.DiskUsage;

import org.hyperic.sigar.FileSystem;

import org.hyperic.sigar.FileSystemUsage;

import org.hyperic.sigar.NetInterfaceConfig;

import org.hyperic.sigar.NetInterfaceStat;

import org.hyperic.sigar.Sigar;

import org.hyperic.sigar.SigarProxy;

import org.hyperic.sigar.SigarProxyCache;

import org.hyperic.sigar.Swap;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;


public class HostPerf {


private static final Logger LOGGER = LoggerFactory.getLogger(HostPerf.class);


static int SLEEP_TIME = 2000;

static Sigar sigarImpl = new Sigar();

static SigarProxy sigar = SigarProxyCache.newInstance(sigarImpl, SLEEP_TIME);


public static Map<String, Float> getCpuUsage() throws Exception {

Map<String, Float> cpuInfo = new HashMap<String, Float>();

CpuPerc cpuPerc = sigar.getCpuPerc();

float idle = (float) cpuPerc.getIdle();

float cpu = (float) ((1.0D - idle) * 100.0D);

float sysCpu = (float) cpuPerc.getSys() * 100.0F;

float userCpu = (float) cpuPerc.getUser() * 100.0F;


cpuInfo.put("cpuUsed", cpu);

cpuInfo.put("cpuFree", idle);

cpuInfo.put("sysCpu", sysCpu);

cpuInfo.put("userCpu", userCpu);


return cpuInfo;

}


public static Map<String, Float> getMemInfo() throws Exception {

Map<String, Float> memInfo = new HashMap<String, Float>();

Mem m = sigar.getMem();

float tmem = m.getTotal();

float fmem = m.getActualFree();

float umem = m.getActualUsed();

float memrate = (float) m.getUsedPercent();

memInfo.put("memTotal", tmem);

memInfo.put("memFree", fmem);

memInfo.put("memUsed", umem);

memInfo.put("memRate", memrate);


Swap sw = sigar.getSwap();


float pagein = sw.getPageIn();

float pageout = sw.getPageOut();

float tswap = sw.getTotal();

float uswap = sw.getUsed();

float swaprate = tswap == 0L ? 0.0F : (float) uswap * 100.0F / (float) tswap;


memInfo.put("pageIn", pagein);

memInfo.put("pageOut", pageout);

memInfo.put("swapTotal", tswap);

memInfo.put("swapUsed", uswap);

memInfo.put("swapRate", swaprate);


return memInfo;

}

}


소스코드를 수행하면 다음과 같은 오류메세지가 발생한다.


■ 오류 


no sigar-amd64-winnt.dll in java.library.path

org.hyperic.sigar.SigarException: no sigar-amd64-winnt.dll in java.library.path 

위의 오류를 해결하기 위해 sigar에서 제공하는 OS 환경에 맞는 Library를 설정해야한다.


먼저 hyperic-sigar-1.6.4.zip를 다운로드하여 압축을 해제한 후 Runtime 환경에 맞는 Library를 디렉토리에 Copy 한다.


프로그램을 실행할 때 JVM 파라미터로 -Djava.library.path=Library Directory 입력한 후 프로그램을 실행한다.


■ 실행결과


 


{cpuFree=0.92296225, cpuUsed=7.7037754, userCpu=1.4910537, sysCpu=5.417495}

{memFree=6.194135E8, swapUsed=6.4725484E9, memTotal=4.19631923E9, swapTotal=8.3907338E9, pageIn=2.0350976E8, memUsed=3.57690573E9, pageOut=1691194.0, swapRate=77.139244, memRate=85.23912}

Java에서 Shell호출 방법


Java 2018. 7. 5. 09:59

Java에서 Shell 호출 시 apache commons-exec를 사용하면 쉽게 shell을 호출하고 shell에 파라미터 전달도 가능하다.


■ 소스

import java.io.ByteArrayOutputStream;

import java.util.HashMap;

import java.util.Map;


import org.apache.commons.exec.CommandLine;

import org.apache.commons.exec.DefaultExecuteResultHandler;

import org.apache.commons.exec.DefaultExecutor;

import org.apache.commons.exec.ExecuteStreamHandler;

import org.apache.commons.exec.ExecuteWatchdog;

import org.apache.commons.exec.PumpStreamHandler;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.servlet.ModelAndView;


import ncd.spring.common.util.PropertyUtil;


@Controller

public class DeployController {


private static final Logger LOGGER = LoggerFactory.getLogger(DeployController.class);

@RequestMapping(value = "/admin/deploy.do")

public ModelAndView sourceDeploy(@RequestParam("type") String type) throws Exception {

LOGGER.info("Start Source Deploy....");

final Map<String, Object> resultMap = new HashMap<String, Object>();


String scriptFile  = PropertyUtil.getString("deploy.script.file");

String confFile = null;

if ("oz".equals(type)) {

confFile = PropertyUtil.getString("oz.deploy.config.file");

}

else {

confFile = PropertyUtil.getString("was.deploy.config.file");

}

if (scriptFile == null || confFile == null) {

resultMap.put("error", "script file or config file is null");

return new ModelAndView("ajaxMultiDataView", resultMap);

}

LOGGER.info("{},{}", scriptFile, confFile);

/** Initiate Executor **/

DefaultExecutor executor = new DefaultExecutor();

ExecuteWatchdog watchDog = new ExecuteWatchdog(60*1000);

executor.setWatchdog(watchDog);

DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();

ByteArrayOutputStream bos = new ByteArrayOutputStream();

ExecuteStreamHandler stream = new PumpStreamHandler(bos, bos, null);

executor.setStreamHandler(stream);

/** Initiate Command Line **/

CommandLine cmdLine = new CommandLine(PropertyUtil.getString("deploy.script.command"));

/** Set parameter to command line **/

cmdLine.addArgument(scriptFile);

cmdLine.addArgument(confFile);

cmdLine.addArgument(type);

LOGGER.info("Execute Command :: ", cmdLine.toString());

/** Execute shell **/

try {

executor.execute(cmdLine, resultHandler);

resultHandler.waitFor();

int exitCode = resultHandler.getExitValue();

String result = bos.toString();

LOGGER.info("Result :: ", result);

resultMap.put("result", result);

resultMap.put("exitCode", exitCode);

}

catch(Exception ex) {

LOGGER.error(ex.getMessage());

}

finally {

bos.close();

}

ModelAndView mav = new ModelAndView("ajaxMultiDataView", resultMap);

return mav;

}



Shell의 수행결과를 받기 위해서는 PumpStreamHandeler를 생성하고, executer에 StreamHanlder에 Set한다.
