主機日常效能資料採集

對於我們日常的維護和分析來說，儲存一份主機日常效能採集的資料是非常有必要的。可以讓我們在事後檢視需要檢視的那段時間的主機資源使用情況，也可以據此，我們來做一份分析報告。

1、AIX平臺
在AIX平臺下，我們可以藉助nmon工具很方便的實現這個需求。我們需要做的就是上傳nmon工具，然後在crontab中部署一個計劃任務。
0 0 * * * cd /home/xigua ; ./nmon_aix53 -x >> nmon.log 2>&1
-x代表每隔15分鐘做一次取樣，當然如果你認為這個頻率太低，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分鐘採集一次，每天採集720次。


2、HP-UNIX平臺
在hp-unix下面比較麻煩一點，我們需要自己來寫採集的指令碼。指令碼主要是呼叫glance來採集資料。
定義的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 &

這個指令碼負責呼叫4個模組的資料採集，採集的頻率是5分鐘。4個模組的採集資料定義如下 ：
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
}
