saidar(1) General Commands Manual saidar(1)NAME
saidar - a curses-based tool for viewing system statistics
SYNOPSIS
saidar [-d delay] [-c] [-v] [-h]
DESCRIPTION
saidar is a curses-based tool for viewing the system statistics available through libstatgrab. Statistics include CPU, processes, load,
memory, swap, network I/O, disk I/O, and file system information.
OPTIONS
The following options are supported.
-d DELAY
Wait DELAY seconds between updates (default 3)
-c Enables coloured output
-v Prints the version number
-h Display help and exits
COLOURED OUTPUT
When the -c option is used saidar uses colours to display the data. Each area has a different colour to distinguish it from the nearby
fields. Bold and reverse video effects are used to emphasis fields where necessary.
The load average figures are displayed in bold when they're notably (greater that 1) different to each other. This purely shows that a
change in the load is occurring.
When CPU usage goes over 60% it will be displayed in bold. At 90% the field is displayed using reverse video. Likewise for memory, swap
and disk usage at 75% and 90%. Zombie processes are also highlighted.
Other values (paging, disk I/O and network I/O) are not highlighted due to the nature of the values; it's not easy to determine what
thresholds are significant.

sg_get_page_stats(3) Library Functions Manual sg_get_page_stats(3)NAME
sg_get_page_stats, sg_get_page_stats_diff - get paging statistics
SYNOPSIS
#include <statgrab.h>
sg_page_stats *sg_get_page_stats(void);
sg_page_stats *sg_get_page_stats_diff(void);
DESCRIPTION
sg_get_page_stats and sg_get_page_stats_diff both return a pointer to a static buffer of type sg_page_stats.
sg_get_page_stats will return the number of pages the system has paged in and out since bootup. sg_get_page_stats_diff will return the
difference since last time it was called. If it has not been called before, it will return sg_get_page_stats.
RETURN VALUES
typedef struct{
long long pages_pagein;
long long pages_pageout;
time_t systime;
}sg_page_stats;
pages_pagein
The number of pages swapped into memory.
pages_pageout
The number of pages swapped out of memory (to swap).
systime
The time period over which pages_pagein and pages_pageout were transferred.
BUGS
Solaris doesn't seem to report accurately. It reports the number of pages swapped into memory, not necessarily from swap. This feature
isn't deemed entirely reliable.
