Hello,
I just put together a new orcallator.se release that has many
improvements. Here are the comments relating to the changes
since orcallator.se was released with Orca 0.23.
I'll also start listing these separately from Orca on my
web site.
Blair
// 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.
-------------- next part --------------
//
// Orcallator.se, a log generating performance monitor.
//
// This program logs many different system quantities to a log file
// for later processing.
