Monitoring the output of 'top' command on hourly basis.

UNIX Solaris
1

I need to capture the following data on an hourly basis through cronjob scheduling:-

  1. load averages
  2. Total no. of processes.
  3. CPU state
  4. Memory
  5. Top 3 process details.

All the above information is available through the command 'top'. But here we need to automate the same and save it in a log file for the purpose of monitoring the server performance.

Please find the below data which exactly I need to capture:-

 
load averages:  0.30,  0.29,  0.24                                          
90 processes:  88 sleeping, 2 on cpu
CPU states: 97.7% idle,  1.7% user,  0.6% kernel,  0.0% iowait,  0.0% swap
Memory: 16G real, 11G free, 3333M swap in use, 13G swap free
   PID USERNAME LWP PRI NICE  SIZE   RES STATE    TIME    CPU COMMAND
 29490 oms1      47   0   12  172M  140M cpu/0   55:40  0.75% java
  2436 sroy       1  59    0 7208K 6088K cpu/8    0:54  0.52% top
  2482 avijay     1  32    0 7080K 5960K sleep    0:01  0.26% top

Request you to please provide some idea or any automation script how the above activity can be performed.

Thank you all in advance.

Sorry for not mentioning, the requirement is for Solaris 10 environment.

i'll recommend SAR for doing this...

System Activity Reporter (sar)

3

1: `w|head -1`
2: `ps -e|wc -l`
3&4: `vmstat 1 2|tail -1`
5: `ps -elfy|sort +4n -r|head -3`

EDIT:
Duke is right, `sar` is the best way to do this.

Probably you can write a cron job which updates a log file as

top >> monitor.log

schedule it to run every 5 min or desired frequency.

This must help

5 
# Run top every minute for 60 minutes
/usr/local/bin/top -c -s 60 -d 60 >> $TOPLOG
