<p>I'm trying to write a simple program to alert me when ram is getting fulled, but I've some problems with sysinfo(), the sample program is in C, I've grabbed it from a site with examples the code seems to be okay, any ideas of why this can be happening ? sorry about my english it's not my native language... </p> <p>code is below:</p> <pre><code>/* sysinfo.c by detour@metalshell.com * * Display the uptime, load averages, total ram, free ram, * shared ram, buffered ram, total swap, free swap, and * number of processes running on a linux machine. * * http://www.metalshell.com/ * */ #include <sys/sysinfo.h> #include <stdio.h> int main() { int days, hours, mins; struct sysinfo sys_info; if(sysinfo(&sys_info) != 0) perror("sysinfo"); // Uptime days = sys_info.uptime / 86400; hours = (sys_info.uptime / 3600) - (days * 24); mins = (sys_info.uptime / 60) - (days * 1440) - (hours * 60); printf("Uptime: %ddays, %dhours, %dminutes, %ldseconds\n", days, hours, mins, sys_info.uptime % 60); // Load Averages for 1,5 and 15 minutes printf("Load Avgs: 1min(%ld) 5min(%ld) 15min(%ld)\n", sys_info.loads[0], sys_info.loads[1], sys_info.loads[2]); // Total and free ram. printf("Total Ram: %ldk\tFree: %ldk\n", sys_info.totalram / 1024, sys_info.freeram / 1024); // Shared and buffered ram. printf("Shared Ram: %ldk\n", sys_info.sharedram / 1024); printf("Buffered Ram: %ldk\n", sys_info.bufferram / 1024); // Swap space printf("Total Swap: %ldk\tFree: %ldk\n", sys_info.totalswap / 1024, sys_info.freeswap / 1024); // Number of processes currently running. printf("Number of processes: %d\n", sys_info.procs); return 0; } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
