Daily check helth

Can any one suggest some command that used to test the hardware and software

The error logger in AIX provides extencive diagnostics information when it is needed. Usually there is no need to perform health check on hardware if you just keep an eye on the error log.

How Can I get the error log? please Urgent

man errpt.

Thank you, sir on this matter because I benefited from it, and I hope to contact regarding this matter
