Hi,

Is there any default script available for the same ?

I think you should have a look at the man pages of commands like,

man top
man df
man vmstat

etc.

AIX and HP-UX are quite similar...
What are you looking for?
Most people configure those servers in such a way any system alert shows up in logs, all you have to do is look at them by looking at /var/adm/syslog/syslog.log for HP and typing errpt -a on AIX.
If its monitoring you are thing about, its quite different...

I am looking for some scripts which will give some feedback after the health check(may give a single 'ok' as o/p). Bcoz this i need to do it on a huge environment with more than 1000 servers. So if i am giving commands like df -h & vmstat, it is very difficult to go and check outputs of each commands in servers.

You could write a script and/or configure the logger (/etc/syslog.conf) to get those lines from syslogs and send them to a centralized common log on a promoted server for this task, so you only have one to look at...
e.g. a line like *.err @<promoted server>

man logger

I dont think it is readily available for you to say, just ok.

You have to analyze what all you need, such as output of top command, uptime, free -om, df -h and so on. And then cross check with the parameters you are looking for. And print an ok ...

If something you find it, contribute it to here...
