system.stat - script to test all possible parameters

Usage: system.stat [zabbix_get options]

"-k <key>" options are generated automatically. You may want to adjust the full path to bash in the script header.

Are other items working fine on that "6100-06"?
Is there any error message in the Zabbix agent log running on that machine, e. g. something about "collector"?

The problem is accessing perfstat data on a Aix 6.1 6100-06:

12255382:20120622:180210.861 perfstat_disk_total: [22] Invalid argument

So the perfstat_disk_total() call returns 22 (EINVAL) which means "One of the parameters is not valid".

Waiting for the information from reporter about accessing the machine where the problem occurred.

On the machine where system.stat is not working, try next simple program:

#include <stdio.h>
#include <stdlib.h>
#include <libperfstat.h>

int main(int argc, char* argv[]) {
perfstat_disk_total_t dinfo;
int rc;
rc = perfstat_disk_total(NULL, &dinfo, sizeof(perfstat_disk_total_t), 1);
if (rc != 1)

perfstat_disk_total(NULL, &dinfo, sizeof(perfstat_disk_total_t), 1);
printf("Total disk statistics\n");
printf("---------------------\n");
printf("number of disks : %d\n", dinfo.number);
printf("total disk space : %llu\n", dinfo.size);
printf("total free space : %llu\n", dinfo.free);
printf("number of transfers : %llu\n", dinfo.xfers);
printf("number of blocks written : %llu\n", dinfo.wblks);
printf("number of blocks read : %llu\n", dinfo.rblks);

exit(EXIT_SUCCESS);
}

Save it to a file perfstat_disk.c and run (change "cc" to "gcc" if you want to use GNU C Compiler):

cc -Wall -o perfstat_disk -lperfstat perfstat_disk.c && ./perfstat_disk

If that gives error, run next commands and report their output:

iostat -d
iostat -d 2
lsattr -E -l sys0 -a iostat

I was thinking maybe perfstat_disk_total() fails due to disabled disk stats collection. Here is more info and also information how to enable disk collection:

Please note that I'm not AIX system expert so I'd appreciate if someone has something to comment.

Please run attached script ZBX-5186-collect.sh in order to collect perfstat related info (after compiling the program mentioned in previous comment):

Save the ZBX-5186-collect.sh script to directory where perfstat_disk.c was compiled and run:

chmod +x ZBX-5186-collect.sh
./ZBX-5186-collect.sh

After that attach generated log file ZBX-5186.log .

OK the attached file was sent to me in private. It appeared that on one of the machines libperfstat was broken. Even the sample programs that come with libperfstat package were not working on that machine. Closing it, please feel free to reopen if you feel that the problem is still there.

In regards to system.stat[ent] ZBX-12270 could possibly have been the cause here as well.
