Linux部署nmon监控

 从http://nmon.sourceforge.net/pmwiki.php?n=Site.Download

 
下载对应版本nmon
 
将下载文件重命名为nmon
 
复制到Linux的/usr/bin,
 
chmod +x /usr/bin/nmon
 
接下来就可以使用nmon了
 
或者随便放自己喜欢放置的地方,记得设置环境变量也一样
 
配置一个收集进程ID的sh
while [ 1=1 ]
do
ps -ef ;sleep 300 >> /pslog/pslog_$(date +%Y%m%d%H).log
done
 
另外可以配置crontab
*/5 * * * * /pslog/pslog.sh 2 >/dev/null
[root@RHEL6 /root]$cat /pslog/pslog.sh
echo $(date +%Y"-"%m"-"%d" "%H":"%M":"%S) >> /pslog/pslog_$(date +%Y%m%d%H%M).log
ps -ef  >> /pslog/pslog_$(date +%Y%m%d%H%M).log
echo "" >> /pslog/pslog_$(date +%Y%m%d%H%M).log
find /pslog -name *.log -mtime +30|xargs rm -rf

附nmon帮助
 
[root@localhost tmp]# nmon -h
 
 
 
Hint: nmon [-h] [-s <seconds>] [-c <count>] [-f -d <disks> -t -r <name>] [-x]
 
 
 
-h            FULL help information
 
Interactive-Mode:
 
read startup banner and type: "h" once it is running
 
For Data-Collect-Mode (-f)
 
-f            spreadsheet output format [note: default -s300 -c288]
 
optional
 
-s <seconds>  between refreshing the screen [default 2]
 
-c <number>   of refreshes [default millions]
 
-d <disks>    to increase the number of disks [default 256]
 
-t            spreadsheet includes top processes
 
-x            capacity planning (15 min for 1 day = -fdt -s 900 -c 96)
 
 
 
Version - nmon 14g
 
 
 
For Interactive-Mode
 
-s <seconds>  time between refreshing the screen [default 2]
 
-c <number>   of refreshes [default millions]
 
-g <filename> User Defined Disk Groups [hit g to show them]
 
             - file = on each line: group_name <disks list> space separated
 
             - like: database sdb sdc sdd sde
 
             - upto 64 disk groups, 512 disks per line
 
             - disks can appear more than once and in many groups
 
-b            black and white [default is colour]
 
example: nmon -s 1 -c 100
 
 
 
For Data-Collect-Mode = spreadsheet format (comma separated values)
 
Note: use only one of f,F,z,x or X and make it the first argument
 
-f            spreadsheet output format [note: default -s300 -c288]
 
output file is <hostname>_YYYYMMDD_HHMM.nmon
 
-F <filename> same as -f but user supplied filename
 
-r <runname>  used in the spreadsheet file [default hostname]
 
-t            include top processes in the output
 
-T            as -t plus saves command line arguments in UARG section
 
-s <seconds>  between snap shots
 
-c <number>   of snapshots before nmon stops
 
-d <disks>    to increase the number of disks [default 256]
 
-l <dpl>      disks/line default 150 to avoid spreadsheet issues. EMC=64.
 
-g <filename> User Defined Disk Groups (see above) - see BBBG & DG lines
 
-N            include NFS Network File System
 
-I <percent>  Include process & disks busy threshold (default 0.1)
 
             don't save or show proc/disk using less than this percent
 
-m <directory> nmon changes to this directory before saving to file
 
example: collect for 1 hour at 30 second intervals with top procs
 
nmon -f -t -r Test1 -s30 -c120
 
 
 
To load into a spreadsheet:
 
sort -A *nmon >stats.csv
 
transfer the stats.csv file to your PC
 
Start spreadsheet & then Open type=comma-separated-value ASCII file
 
The nmon analyser or consolidator does not need the file sorted.
 
 
 
Capacity planning mode - use cron to run each day
 
-x            sensible spreadsheet output for CP =  one day
 
             every 15 mins for 1 day ( i.e. -ft -s 900 -c 96)
 
-X            sensible spreadsheet output for CP = busy hour
 
             every 30 secs for 1 hour ( i.e. -ft -s 30 -c 120)
 
 
 
Interactive Mode Commands
 
key --- Toggles to control what is displayed ---
 
h   = Online help information
 
r   = Machine type, machine name, cache details and OS version + LPAR
 
c   = CPU by processor stats with bar graphs
 
l   = long term CPU (over 75 snapshots) with bar graphs
 
m   = Memory stats
 
L   = Huge memory page stats
 
V   = Virtual Memory and Swap stats
 
k   = Kernel Internal stats
 
n   = Network stats and errors
 
N   = NFS Network File System
 
d   = Disk I/O Graphs
 
D   = Disk I/O Stats
 
o   = Disk I/O Map (one character per disk showing how busy it is)
 
o   = User Defined Disk Groups
 
j   = File Systems 
 
t   = Top Process stats use 1,3,4,5 to select the data & order
 
u   = Top Process full command details
 
v   = Verbose mode - tries to make recommendations
 
b   = black and white mode (or use -b option)
 
.   = minimum mode i.e. only busy disks and processes
 
 
 
key --- Other Controls ---
 
+   = double the screen refresh time
 
-   = halves the screen refresh time
 
q   = quit (also x, e or control-C)
 
0   = reset peak counts to zero (peak = ">")
 
space = refresh screen now
 
 
 
Startup Control
 
If you find you always type the same toggles every time you start
 
then place them in the NMON shell variable. For example:
 
export NMON=cmdrvtan
 
 
 
Others:
 
a) To you want to stop nmon - kill -USR2 <nmon-pid>
 
b) Use -p and nmon outputs the background process pid
 
c) To limit the processes nmon lists (online and to a file)
 
  Either set NMONCMD0 to NMONCMD63 to the program names
 
  or use -C cmd:cmd:cmd etc. example: -C ksh:vi:syncd
 
d) If you want to pipe nmon output to other commands use a FIFO:
 
  mkfifo /tmp/mypipe
 
  nmon -F /tmp/mypipe &
 
  grep /tmp/mypipe
 
e) If nmon fails please report it with:
 
  1) nmon version like: 14g
 
  2) the output of cat /proc/cpuinfo
 
  3) some clue of what you were doing
 
  4) I may ask you to run the debug version
