I don't think anybody actually asked that... I'm more interested in the answers to his other questions about the situation of your system.
"load average" doesn't tell us much about what's happening from moment-to-moment. It's like asking "my car is hot, what's wrong with it?" Well, maybe you've got the heater on, or it's a warm day. Or the air-conditioning is broken. Or maybe it's on fire... We can't really see your car from here, you'll have to tell us a little more about what's going on.
What's it look like in ps or top?

Hi guys,
I need a script that will generate a core of a process when the process uses high cpu for a sustained period?
So for example if a process is using greater than 80% cpu for more than 30 minutes do "gcore /var/tmp/process.core pid" (1 Reply)

Hi,
could someone give me an example for a debian server script? I need to check a process if the process has a high cpu load (top).
If yes the whole server needs to reboot.
Thats it, nothing more. ;)
Hope someone could help me.

NAME
trafgen - a high-performance zero-copy network packet generator
SYNOPSIS
trafgen [-d|--dev <netdev>][-c|--conf <file>][-J|--jumbo-support] [-x|--interactive][-n|--num <uint>][-r|--rand][-t|--gap <usec>]
[-S|--ring-size <size>][-k|--kernel-pull <usec>][-b|--bind-cpu <cpu>] [-B|--unbind-cpu
<cpu>][-H|--prio-high][-Q|--notouch-irq][-v|--version] [-h|--help]
DESCRIPTION
A high-performance network traffic generator that uses the zero-copy TX_RING for network I/O. For instance, on comodity Gigabit hardware up
to 1,488,095 pps 64 Byte pps have been achieved with trafgen.
OPTIONS
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0
Use packet configuration trafgen.txf, eth0 as transmission device and CPU0 for binding the process.
OPTIONS
-h|--help
Print help text and lists all options.
-v|--version
Print version.
-d|--dev <netdev>
Device for transmission i.e., eth0.
-c|--conf <conf>
Path to packet configuration file.
-x|--interactive
Start trafgen in interactive mode.
-J|--jumbo-support
Support for 64KB Super Jumbo Frames
-n|--num <uint>
Number of packets to generate before exiting. 0 means forever until SIGINT.
-r|--rand
Randomize packet selection process instead of round-robin.
-t|--gap <uint>
Interpacket gap in microseconds.
-S|--ring-size <size>
Manually set ring size to <size>: mmap space in KB/MB/GB.
-k|--kernel-pull <uint>
Kernel pull from user interval in microseconds. Default value is 10 microseconds.
-b|--bind-cpu <cpu>
Bind to specific CPU (or CPU-range).
-B|--unbind-cpu <cpu>
Forbid to use specific CPU (or CPU-range).
-H|--prio-high
Make this high priority process.
-Q|--notouch-irq
Do not touch IRQ CPU affinity of NIC.
EXAMPLES
Generate traffic defined in trafgen.txf on eth0 using CPU 0
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0
Generate traffic on eth0 using CPU 0, wait 100 us between packets
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0 --gap 100
Generate 100,000 packet on eth0 using CPU 0
trafgen --dev eth0 --conf trafgen.txf --bind-cpu 0 --num 100000
