Hi, new here and need some help. Sometimes my site is extremely slow, if when there aren't too many people on, whereas when there are over 300 online members the site may be very fast. We use CentOS, PHP 5.26. The server has 4GB and Plesk usually shows about 2 or 3 GB free.
I believe I can see... (4 Replies)
I am running a Dell PE R815 with 4 x AMD 12 core CPUs with 128GB of RAM and a RAID 5 array of 6 SAS disks. This is an HPC application and is definitely CPU bound, however once I run 16 of these processes (thus pinning 16 cores) the work performed slows down dramatically, to maybe 5 or 10% of what...

vxmemstat
vxmemstat(1M)vxmemstat(1M)NAME
vxmemstat - display memory statistics for Veritas Volume Manager
SYNOPSIS
vxmemstat [-e] [-i interval [-t count]]
DESCRIPTION
The vxmemstat utility prints memory statistics information. This information can be system-wide, or it can be specific to a Veritas Volume
Replicator object.
OPTIONS -e Prints extended memory statistics.
-i interval
Prints memory statistics every interval seconds.
-t count Prints the local system time every count intervals. The time interval is specified using the -i interval option.
OUTPUT FORMAT
The statistics are prefaced by a timestamp showing the current local time on the system. Statistics are printed as a one-line output record
for each memory pool. The records are preceded by two header lines. The output line consists of blank-separated fields. All numeric fields
are in units of kilobytes.
The following fields are displayed on each line:
Pool Name of the memory pool. Memory consumers allocate memory from different pools for different purposes.
DG Name of the disk group in which the RVG is present.
Min Size Minimum amount of memory always reserved for use by consumers of the pool. As consumers require more memory, additional memory is
allocated to the pool for distribution to them.
Max Size Maximum amount of memory that can be allocated to the pool. This is equal to the value assigned to the maximum pool size system
tunable that corresponds to the pool.
In Use Amount of memory (out of that allocated) currently being used by consumers of the memory pool.
Allocated Amount of memory currently allocated to the memory pool. The amount of memory allocated to a pool ranges between the minimum and
the maximum pool size. The amount of allocated memory increases as more memory is needed and decreases as it is relinquished.
Max Used Maximum amount of memory used by consumers from this pool since system startup.
This field is not shown if the -e option is specified.
Max Pool Used
Maximum amount of memory used by consumers from this pool at any time since the last reboot. The value shows the maximum usage
even if usage by the pool has varied over this time period.
This field is shown if the -e option is specified.
Waiting Indicates if any I/O is waiting to allocate memory from this pool. This usually indicates that the corresponding tunable for the
maximum size of this pool needs to be increased.
This field is not shown if the -e option is specified.
Waiters The number of requests that are waiting to allocate memory from this pool.
This field is shown if the -e option is specified.
EXIT CODES
The vxmemstat utility exits with a non-zero status if the attempted operation fails. A non-zero exit code is not a complete indicator of
the problems encountered, but rather denotes the first condition that prevented further execution of the utility.
See vxintro(1M) for a list of standard exit codes.
EXAMPLES
To display statistics every 5 seconds and time stamp the output every alternate interval, use the command:
vxmemstat -i 5 -t 2
