Solaris

I have written a Shell which is been added to Crontab to execute few commands which Monitors my solaris boxes.
some commands aren't writing the logs(its Blank). but If I run directly it writes the log.
Ex: dfspace >> /unused1/Monitoring/Log/log_110.txt,

display message priority critical start '09/09 12:00:00' stop '09/10 11:59:59' all >> /unused1/Monitoring/Log/log_110.txt,

and have the same 10 boxes, am checking the same through shell script and transferring the log to a single Box with different file names
would like to this remotely on all the boxes at once every 3 hours.
Please help me with this

as always please check out the FAQs first.

1) who is the user running the crontab
2) rights/access to program and/or to the file to be written
3) path settings

Have you looked into those issues?

It's the user root on all the boxes.
as I explained, the Log written for the same sometimes when I directly run the Shell Directly, not always

thanks for sharing - follow the FAQ link provided above.
good luck.

I found the answer,
When we need some commands to run automatically through crontab, we need to execute them from the executable location,
Ex: /vs/bin/logCat -t30 >> /unused1/Monitoring/Log/log_110.txt
and
/vs/bin/tools/dfspace >> /unused1/Monitoring/Log/log_110.txt
would execute and write the logs with out any issues
