I/O Stats Metrics

What do others use for measuring I/O statistics? I'd like something versatile, as in being able to watch (like iostat, but easier to trend), generate load (like iozone, but more realistic), and perform somewhat generalized benchmarks (like bonnie, but more current.) It would scale from a few filesystems to several hundred filesystems.

Another utility I'd like to keep my eye for would be a way to list outstanding lock operations...

This would all be used on GNU/Linux systems, SLES and RHEL. Basically, generate a load of read/write activity similar to production without having actual production - piece of cake, no?

Unix Metrics

Hi, Does anyone know of any programs that can create Unix (Solaris) server metrics such as server uptime, services uptime, processor utilization by hour by day, memory utilization by hour by day, active users by hour by day, etc? Thanks!

Audio::MPD::Common::Stats(3pm)				User Contributed Perl Documentation			    Audio::MPD::Common::Stats(3pm)

NAME

       Audio::MPD::Common::Stats - class representing MPD stats

VERSION

       version 1.120881

DESCRIPTION

       The MPD server maintains some general information. Those information can be queried with the mpd modules. Some of those information are
       served to you as an Audio::MPD::Common::Stats object.

       An Audio::MPD::Common::Stats object does not update itself regularly, and thus should be used immediately.

       Note: one should never ever instantiate an Audio::MPD::Common::Stats object directly - use the mpd modules instead.

ATTRIBUTES

   $stats->artists;
       Number of artists in the music database.

   $stats->albums;
       Number of albums in the music database.

   $stats->songs;
       Number of songs in the music database.

   $stats->uptime;
       Daemon uptime (time since last startup) in seconds.

   $stats->playtime;
       Time length of music played.

   $stats->db_playtime;
       Sum of all song times in the music database.

   $stats->db_update;
       Last database update in UNIX time.
