disk usage
Hi,
How can I measure disk usage? Cpu, memory, NIC usage are not at 100% and no
matter how much concurrent users is increased, the ops/sec stays the same.
regards,

Thanks!
NFS server and MySQL Server are running on the same computer.
Got this line from "top" program during a benchmark:
*Cpu(s): 32.2%us, 7.2%sy, 0.0%ni, 28.6%id, 30.1%wa, 0.6%hi, 1.3%si,
0.0%st*
does processes in wait "mode" are waiting for NIC, disk i/o or both?
When fenxi tries to use iostat data (from the mentioned server) it presents
an error:
* Overall System Activity (per second)*
*org.apache.derby.impl.jdbc.EmbedSQLException: Column 'RPS' is either not in
any table in the FROM list or appears within a join specification and is
outside the scope of the join specification or appears in a HAVING clause
and is not in the GROUP BY list. If this is a CREATE or ALTER TABLE
statement then 'RPS' is not a column in the target table.
