RAM and CPU

CPU Usage

• The CPU usage tells the percentage of time that the processor has spent on specific applications, including Windows functions. Even when the CPU usage is at 0 percent, the CPU is constantly performing low-level tasks, such as responding to the keyboard and mouse movements.

RAM

• RAM is found in modules that are plugged into the computer's motherboard. Each open application takes up a certain amount of RAM. This is not storage memory, but simply the memory required to actually run the programs. RAM is probably the easiest part of a computer to upgrade when seeking to improve computer performance.

The Difference

• The CPU is the component that moves files to and from the RAM as they are utilized. The CPU is responsible for the actual management of the files, whereas RAM is simply the place the files are temporarily placed.

Using Lights Out Management and the System Controller from Solaris

This chapter explains how to use the LOM-specific commands available in Solaris for monitoring and managing a Sun Fire entry-level midrange systems system. To use these commands you should install the Lights Out Management 2.0 packages (SUNWlomr, SUNWlomu and SUNWlomm) from the Solaris Supplemental CD. Refer to To Install the Lights Out Management Packages for a description of how to install the LOM packages.

---

Note - The latest patches to these packages is available from SunSolve in patch 110208. It is strongly advised that the latest version of patch 110208 is obtained from SunSolve and is installed on the Sun Fire entry-level midrange systems to make use of the latest LOM utility updates.

---

The chapter contains the following sections:

• Monitoring the System From Solaris
• Other LOM Tasks Performed From Solaris

---

LOM Command Syntax

lom [-c] [-l] [-f] [-v] [-t] [-a] [-G] [-X]
lom -e , [x] lom -A on|off  lom -E on|off

where:

-c displays LOM configuration.

-l displays the status of the Fault and Alarms LEDs.

-e displays the event log.

-f displays fan status. This information is also displayed in the output from the Solaris prtdiag -v command.

-v displays the status of the voltage sensors. This information is also displayed in the output from the Solaris prtdiag -v command.

-t displays temperature information. This information is also displayed in the output from the Solaris prtdiag -v command.

-a displays all component status data.

-A turns alarms on and off.

-X changes the escape sequence.

-E switches event logging to the console on and off.

-G upgrades the firmware.

---

Monitoring the System From Solaris

There are two ways of interrogating the LOM device (System Controller) or of sending it commands to perform:

• By executing LOM commands from the lom> shell prompt

For information about how to do this, see Chapter 3.

• By executing LOM-specific Solaris commands from the UNIX # prompt

These commands are described in this chapter.

The Solaris commands described in this section, which are all available from the UNIX # prompt, run the /usr/sbin/lom utility.

Where appropriate, the command lines given in this section are accompanied by typical output from the commands.

Viewing Online LOM Documentation

To view the manual pages for the LOM utility, type:

# man lom

Viewing the LOM Configuration (lom -c)

To view the current LOM configuration, type:

CODE EXAMPLE 5-1 Sample Output from the lom -c Command

# lom -c LOM configuration settings: serial escape sequence=#. serial event reporting=default Event reporting level=fatal, warning & information firmware version=5.17.0, build 5.0 product ID=Netra T12

Checking the Status of the Fault LED and Alarms (lom -l)

To check whether the System Fault LED and alarms are on or off, type:

CODE EXAMPLE 5-2 Sample Output from the lom -l Command

# lom -l LOM alarm states: Alarm1=off Alarm2=off Alarm3=on Fault LED=off #

Alarms 1 and 2 are software flags. They are associated with no specific conditions but are available to be set by your own processes or from the command line (see Turning Alarms On and Off (lom -A)). Alarm 3 is UNIX Running and is not user-configurable.

Viewing the Event Log (lom -e)

To see the event log, type:

# lom -e n,[x]

where n is the number of reports (up to 128) that you want to see and x specifies the level of reports you are interested in. There are four levels of event:

1. Fatal events

2. Warning events

3. Information events

4. User events (not used on Sun Fire entry-level midrange systems systems)

If you specify a level, you will see reports for that level and above. For example, if you specify level 2, you will see reports of level 2 and level 1 events. If you specify level 3, you will see reports of level 3, level 2, and level 1 events.

If you do not specify a level, you will see reports of level 3, level 2, and level 1 events.

CODE EXAMPLE 5-3 shows a sample event log display.

CODE EXAMPLE 5-3 Sample LOM Event Log (Oldest Event Reported First)

# lom -e 11 LOMlite Event Log: Fri Jul 19 15:16:00 commando-sc lom: Boot: ScApp 5.13.0007, RTOS 23 Fri Jul 19 15:16:06 commando-sc lom: Caching ID information Fri Jul 19 15:16:08 commando-sc lom: Clock Source: 75MHz Fri Jul 19 15:16:10 commando-sc lom: /N0/PS0: Status is OK Fri Jul 19 15:16:11 commando-sc lom: /N0/PS1: Status is OK Fri Jul 19 15:16:11 commando-sc lom: Chassis is in single partition mode.

Checking the Fans (lom -f)

To check status of the fans, type:

CODE EXAMPLE 5-4 Sample Output from the lom -f Command

# lom -f Fans: 1 OK speed self-regulating 2 OK speed self-regulating 3 OK speed self-regulating 4 OK speed self-regulating 5 OK speed self-regulating 6 OK speed self-regulating 7 OK speed self-regulating 8 OK speed self-regulating 9 OK speed 100 % 10 OK speed 100 % #

If you need to replace a fan, contact your local Sun sales representative and quote the part number of the component you need. For information, see the Sun Fire E2900 System Service Manual or Sun Fire V1280/Netra 1280 Service Manual , as appropriate.

The information output from this command is also contained in the output from the Solaris prtdiag -v command.

Checking the Internal Voltage Sensors (lom -v)

The -v option displays the status of the Sun Fire entry-level midrange systems system internal voltage sensors.

To check the status of the supply rails and internal voltage sensors, type:

CODE EXAMPLE 5-5 Sample Output from the lom -v Command

Viewing All Component Status Data and the LOM Configuration Data (lom -a)

To view all LOM status and configuration data, type:

# lom -a

Other LOM Tasks Performed From Solaris

This section explains how to:

• Turn the alarm indicators on and off
• Change the LOM escape sequence
• Stop the LOM from sending reports to the console
• Upgrade the firmware

Turning Alarms On and Off (lom -A)

There are two alarms associated with the LOM. They are associated with no specific conditions but are software flags available to be set by your own processes or from the command line.

To turn an alarm on from the command line, type:

# lom -A on,n

where n is the number of the alarm you want to set: 1 or 2.

To turn the alarm off again, type:

# lom -A off,n

where n is the number of the alarm you want to turn off: 1 or 2.

Changing the lom> Prompt Escape Sequence
(lom -X)

The character sequence #. (hash, dot) enables you to escape from Solaris to the lom> prompt.

To change the default escape sequence, type:

# lom -X xy

where xy are the alpha-numeric characters you want to use.

---

Note - Quotes may be required for special characters to be interpreted by the shell.

---

---

Note - If you are typing at the console and type the first character of the escape sequence, there is a one second delay before the character appears on the screen. This is because the system waits to see if the next character in the escape sequence is about to be typed. If all the characters in the escape sequence are typed then the lom> prompt appears. If the next character to be typed is not the next character in the escape sequence, then the characters belonging to the escape sequence that were typed are output to the screen.

---

Stopping LOM from Sending Reports to the Console When at the LOM Prompt (lom -E off)

LOM event reports can interfere with information you are attempting to send or receive on the console.

To stop the LOM from sending reports to the console, type:

# lom -E off

To prevent LOM messages displaying when you are at the LOM prompt, turn off serial event reporting. This is equivalent to the seteventreporting command described in the Sun Fire Entry-Level Midrange System Controller Command Reference Manual.

To turn serial event reporting on again, type:

# lom -E on

Upgrading the Firmware (lom -G filename)

Linux Wait I/O what process is causing it ?

How to analyze Wait I/O problem ?

the first thing is to control what kernel version you have.

> 2.6.20 ?

You can use the IOTOP or LATENCYTOP utility that uses the IO_ACCOUNT capability of new kernel

< 2.6.20 ?

block_dump
block_dump enables block I/O debugging when set to a nonzero value.
When this flag is set, Linux reports all disk read and write operations that take place, and all block dirtyings done to files. The output of block_dump is written to the kernel output, and it can be retrieved using "dmesg".
When you use block_dump and your kernel logging level also includes kernel debugging messages, you probably want to turn off klogd, otherwise the output of block_dump will be logged, causing disk activity that is not normally there.

- First you must clear all log in "dmesg"

#dmesg -c 

- Stop any syslog you have for loggin only disk activity

 #/etc/init.d/syslog stop 

- Enable Block_Dump

# echo 1 > /proc/sys/vm/block_dump 

( also sysctl vm.block_dump for read the value and sysctl vm.block_dump=1 to enable the feature)

- Start the reporting: 

#while true; do sleep 1; dmesg -c; done | perl iodump (download iodump script )

- CTRL-C Stop the system from dumping these messages

- Disable Block_Dump after the analisys

#echo 0 > /proc/sys/vm/block_dump 

(also sysctl vm.block_dump for read the value and sysctl vm.block_dump=0 to disable the feature)

- Re-Start any syslog

# /etc/init.d/syslog start

If you prefer, you can save all the block_dump in a log file and then re-elaborate the data.

dmesg -c

/etc/init.d/syslog stop 

echo 1 > /proc/sys/vm/block_dump 

touch /tmp/disklog 

watch "dmesg -c >> /tmp/disklog" 

CTRL-C when you're done collecting data 

echo 0 > /proc/sys/vm/block_dump 

/etc/init.d/syslog start

cat /tmp/disklog | awk -F"[() \t]" '/(READ|WRITE|dirtied)/ {activity[$1]++} END {for (x in activity) print x, activity[x]}'| sort -nr -k2
