主机日常性能数据采集

原创 Linux操作系统 作者:BTxigua 时间:2009-03-10 16:18:32 0 删除 编辑
对于我们日常的维护和分析来说,保存一份主机日常性能采集的数据是非常有必要的。可以让我们在事后查看需要查看的那段时间的主机资源使用情况,也可以据此,我们来做一份分析报告。

1、AIX平台
在AIX平台下,我们可以借助nmon工具很方便的实现这个需求。我们需要做的就是上传nmon工具,然后在crontab中部署一个计划任务。
0 0 * * * cd /home/xigua ; ./nmon_aix53 -x >> nmon.log 2>&1
-x代表每隔15分钟做一次采样,当然如果你认为这个频率太低,可以修改。
例如:
0 0 * * * nmon64 -ft -D -E -I 1 -s 120 -c 720 -m /aixpatch/nmon_out
改成2分钟采集一次,每天采集720次。


2、HP-UNIX平台
在hp-unix下面比较麻烦一点,我们需要自己来写采集的脚本。脚本主要是调用glance来采集数据。
定义的crontab如下:
0 0 * * * cd /glance; ./glance.sh
/glance# more glance.sh
#
# This scripts use glance plus to monitor the performance .
#
#
#
#!/sbin/sh
HOST=`hostname`
DAY=`date '+%Y%m%d'`
cd /glance/
# NETWORK INTERFACE LOOP
nohup /opt/perf/bin/glance -adviser_only -nosort -iterations 288 -j 300 -syntax ./net.adviser >>./log/net_${HOS
T}_${DAY}.log &

# SYSTEM LOOP
nohup /opt/perf/bin/glance -adviser_only -nosort -iterations 288 -j 300 -syntax ./sys.adviser >>./log/sys_${HOS
T}_${DAY}.log &

#PROCESS LOOP
nohup /opt/perf/bin/glance -adviser_only -nosort -iterations 288 -j 300 -syntax ./process.adviser >>./log/proce
ss_${HOST}_${DAY}.log &

#DISK LOOP
nohup /opt/perf/bin/glance -adviser_only -nosort -iterations 288 -j 300 -syntax ./disk.adviser >>./log/disk_${H
OST}_${DAY}.log &

这个脚本负责调用4个模块的数据采集,采集的频率是5分钟。4个模块的采集数据定义如下 :
cat sys.adviser
# This adviser script. prints the global cpu/disk/mem/swap utilization and also
# the network subsystem wait percent for the interval.

headers_printed=headers_printed


IF headers_printed == 0 THEN
{
print "                       CPU    SYS   USER   DISK       PHY_READ      PHY_WRITE    MEM     SWAP  Network"
print " Date      Time       Util   Util   Util   Util           RATE           RATE   Util     Util   Wait %"
print "------------------------------------------------------------------------------------------------------"
headers_printed=1
}

# work for 10.20 you need to remove the "BYNETIF_QUEUE," string

# The following string variable should be changed to the interface
# of interest. For example:
# netif_to_examine = "lan0"
