Performance Monitoring of FileSystem
As I am new to the Unix field, I would like to get the clarification regarding the Filesystem.
The scenario is.. The filesystem (/drbackup) is getting monitored and if it exceeds the threshold, we will receive an alert from it. The issue is that we receive an alert with the description of "Current Utilization exceeds 90%". But whenever I check in the server, it shows the value of only 10% (Current Utilization). So do we have any performance monitoring tool to find when it goes high and get reduced to low ?

hi,
can any one tell me, is there is any way i can check the performance of my solaris 8 os on an Ent 3500. Other than top to check for the top most processes, how to make the calculations with vmstat, iostat, mpstat and nfsstat. Or is there any other tools that i can use?
cheers. (3 Replies)

Hi All
I am looking for a script that would collect statistics in a summarised format.
CPU, Memory,Swap, Wait queue, Run queue and disk activity.
Something that would allow me to profile the environment based on a 1 line output that I could run every 15 min.
Thx

NAME
dpm_modifyfs - modify the parameters of a disk pool filesystem
SYNOPSIS
#include <sys/types.h>
#include "dpm_api.h"
int dpm_modifyfs (char *server, char *fs, int status, int weight)
DESCRIPTION
dpm_modifyfs modifies the parameters of a disk pool filesystem.
server specifies the host name of the disk server where this filesystem is mounted.
fs specifies the mount point of the dedicated filesystem.
status Initial status of this filesystem. It can be set to 0 or FS_DISABLED or FS_RDONLY. (-1 will tell the server to not change the cur-
rent value).
weight specifies the weight of the filesystem. This is used during the filesystem selection. The value must be positive (-1 will tell the
server to not change the current value). It is recommended to use a value lower than 10.
This function requires ADMIN privilege.
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
ERRORS
ENOENT Filesystem does not exist.
EACCES The caller does not have ADMIN privilege.
EFAULT server or fs is a NULL pointer.
EINVAL The length of server exceeds CA_MAXHOSTNAMELEN or the length of fs exceeds 79.
SENOSHOST Host unknown.
