Hello,
Here's a new release of orcallator.se. It does the following changes
since my last release (1.13).
// Version 1.15: Oct 5, 1999 kvm$mpid is a int not a long. This caused
// problems on Solaris 7 hosts running a 64
// bit kernel.
// Version 1.14: Oct 1, 1999 Rename disk.c?t?d? column names to
// disk_runp.c?t?d? to better reflect the data
// being recorded and to allow for more per disk
// information later.
I have also placed it on my website at http://www.geocities.com/~bzking/

-------------- next part --------------
//
// Orcallator.se, a log generating performance monitor.
//
// This program logs many different system quantities to a log file
// for later processing.
//
// Author: Blair Zajac <bzajac at geostaff.com>.
//
// Portions copied from percollator.se written by Adrian Cockroft.
//
// Version 1.15: Oct 5, 1999 kvm$mpid is a int not a long. This caused
// problems on Solaris 7 hosts running a 64
// bit kernel.
// Version 1.14: Oct 1, 1999 Rename disk.c?t?d? column names to
// disk_runp.c?t?d? to better reflect the data
// being recorded and to allow for more per disk
// information later.
// Version 1.13: Sep 24, 1999 Fix a bug in the disk_mean calculation where
// it was being divided by the wrong disk_count.
// Now it should be much larger and in scale with
// disk_peak. When WATCH_DISK is defined, now
// print each disk's run percent. Add a new
// define WATCH_MOUNTS, which reports each mount
// point's disk space and inode capacity, usage,
// available for non-root users and percent used.
// This comes from Duncan Lawie tyger at hoopoes.com.
// Add some smarts so that if the number of
// interfaces, physical disk, or mounted
// partitions changes, then a new header is
// printed. This will prevent column name and
// data mixups when the system configuration
// changes.
// Version 1.12: Sep 14, 1999 Add the page scan rate as scanrate in
// measure_cpu.
// Version 1.11: Aug 13, 1999 Add the number of CPUs as ncpus. Move
// measure_disk and measure_ram sooner in the
// list of subsystems to handle. Increase the
// number of characters for each network
// interface from four to five. Add new disk
// reads, writes, Kbytes read, and Kbytes
// written per second. Add number of bytes
// of free memory in bytes as freememK.
// Version 1.10: Jul 28, 1999 Measure the process spawn rate if WATCH_CPU
// is defined and the user is root.
// Version 1.9: Jun 2, 1999 If WATCH_YAHOO is defined, then process the
// access log as a Yahoo! style access log.
// Restructure the code to handle different
// web server access log formats.
// Version 1.8: Jun 1, 1999 If the environmental variable WEB_SERVER is
// defined, use its value of the as the name
// of the process to count for the number of
// web servers on the system. If WEB_SERVER
// is not defined, then count number of httpd's.
// Version 1.7: Mar 25, 1999 Simplify and speed up count_proc by 20%.
// Version 1.6: Feb 23, 1999 Print pvm.user_time and system_time correctly.
// Version 1.5: Feb 23, 1999 Always write header to a new file.
// Version 1.4: Feb 19, 1999 Handle missing HTTP/1.x in access log.
// Version 1.3: Feb 18, 1999 On busy machines httpops5 will be enlarged.
// Version 1.2: Feb 18, 1999 Output data on integral multiples of interval.
// Version 1.1: Feb 18, 1999 Integrate Squid log processing from SE 3.1.
// Version 1.0: Sep 9, 1998 Initial version.
//
// The default sampling interval in seconds.
#define SAMPLE_INTERVAL 300
// The maximum number of colums of data.
#define MAX_COLUMNS 512
