Operating

system-dependent

variables

and

paths

This

guide

uses

the

UNIX

convention

for

specifying

environment

variables

and

for

directory

notation.

When

using

the

Windows®

command

line,

replace

$variable

with

%variable%

for

environment

variables

and

replace

each

forward

slash

(/)

with

a

backslash

(\)

in

directory

paths.

The

names

of

environment

variables

are

not

always

the

same

in

Windows

and

UNIX.

For

example,

%TEMP%

in

Windows

is

equivalent

to

$tmp

in

UNIX.

Note:

If

you

are

using

the

bash

shell

on

a

Windows

system,

you

can

use

the

UNIX

conventions.

Introduction

IBM

Tivoli

Monitoring

for

Network

Performance

monitors

the

performance

of

networks

and

systems

in

your

enterprise.

Performance

data

from

all

monitored

systems

is

stored

in

a

central

database.

This

data

is

displayed

by

the

Tivoli

Monitoring

for

Network

Performance

Web

application

and

is

also

used

as

input

for

report

generation

using

Tivoli

Data

Warehouse.

Tivoli

Monitoring

for

Network

Performance

meets

your

daily

tactical

needs

as

well

as

your

long-term

strategic

systems

management

goals,

providing

an

effective

way

to

gain

control

of

mission-critical

network

resources,

performance

issues,

and

workload

distributions.

Tivoli

Monitoring

for

Network

Performance

provides

for

the

timely

analysis

of

performance

related

metrics

such

as

response

time,

traffic

flow,

and

system

workload.

Using

the

Tivoli

Monitoring

for

Network

Performance

Web

application,

operators

can

monitor

the

performance

of

the

network

in

an

effort

to

anticipate

problems

and

resolve

them

before

they

occur.

The

performance

data

can

be

used

to

detect

bottlenecks

and

other

potential

problems,

which

eliminates

the

need

for

network

systems

programmers

to

manually

scan

through

extensive

amounts

of

performance

data.

As

shown

in

Figure

on

page

2,

there

are

three

users

of

Tivoli

Monitoring

for

Network

Performance:

Network

systems

programmer

The

network

systems

programmer

is

the

overall

administrator

for

Tivoli

Monitoring

for

Network

Performance

and

is

thus

responsible

for

configuring

and

deploying

the

product.

This

user

is

the

primary

focus

of

the

IBM

Tivoli

Monitoring

for

Network

Performance

Administrator

Guide.

Capacity

planner

The

planner

is

responsible

for

understanding

the

extent

to

which

network

resources

are

being

used,

with

the

goal

of

anticipating

the

need

to

allocate

resources

and

distribute

workload.

Capacity

planners

prepare

reports

containing

resource

usage

and

trends

using

the

Crystal

Reporting

product.

How

to

view

reports

is

documented

in

the

Tivoli

Data

Warehouse

documentation.

Reports

available

with

Tivoli

Monitoring

for

Network

Performance

are

documented

in

the

IBM

Tivoli

Monitoring

Guide.

Network

operator

The

operator

is

responsible

for

the

daily

operations

of

the

network.

This

user

is

mainly

concerned

with

the

health

of

the

network

resources

being

monitored.

This

user

is

the

primary

focus

of

this

manual.

If

you

need

additional

information

about

the

components

of

this

product,

refer

the

IBM

Tivoli

Monitoring

for

Network

Performance:

Planning,

Installation,

and

Configuration.

Overview

of

operator

responsibilities

As

an

operator,

your

responsibilities

include:

v

Monitoring

the

network

for

possible

performance

problems

v

Collecting

data

that

can

be

used

by

the

network

systems

programmer

to

diagnose

and

resolve

performance

problems

Data

collection

Tivoli

Monitoring

for

Network

Performance

collects

performance

data

and

stores

it

in

a

central

database

for

display

by

the

Tivoli

Monitoring

for

Network

Performance

Web

application.

The

network

systems

programmer

specifies

the

categories

of

performance

data

to

be

collected

(such

as

FTP,

IP,

or

TCP)

when

defining

the

monitoring

characteristics

for

each

of

the

monitors.

The

user

interface

is

organized

to

reflect

the

different

categories

of

performance

data

that

you

can

view.

The

monitor

collects

many

different

pieces

of

data

(metrics)

for

each

category.

For

example,

the

monitor

collects

more

than

a

dozen

performance

metrics

for

each

z/OS

TCP/IP

stack

being

monitored.

Each

row

of

data

that

is

displayed

in

the

user

interface

tables

represents

a

resource,

connection,

or

session

that

is

being

monitored.

Some

of

the

fields

are

used

to

uniquely

identify

the

entity

that

is

being

monitored.

For

example,

the

IP

address,

system

name,

and

sysplex

name

are

used

to

uniquely

identify

a

z/OS

TCP/IP

stack.

The

remaining

data

directly

relate

to

the

health

and

performance

of

the

resources,

connections,

or

sessions

being

monitored.

For

example,

if

the

network

systems

programmer

is

collecting

TCP

performance

data,

the

monitor

collects

up

to

metrics

related

to

the

performance

of

the

TCP

layer

for

each

IP

stack

being

monitored.

For

each

of

these

metrics,

the

network

systems

programmer

can

optionally

provide

a

threshold

value.

When

the

monitor

collects

performance

data,

each

metric

is

compared

to

the

threshold

value

if

one

was

specified.

If

the

value

of

a

metric

crosses

its

associated

threshold,

a

red

error

indicator

is

displayed

next

to

that

value

when

the

Tivoli

Monitoring

for

Network

Performance

user

interface

displays

the

performance

data.

The

network

systems

programmer

also

specifies

when

and

how

often

data

are

collected.

For

example,

the

monitoring

characteristics

might

be

specified

to

collect

performance

data

every

15

minutes,

from

8:00

a.m.

to

5:00

p.m.,

Monday

through

Friday.

For

most

categories

of

data,

the

monitor

initiates

data

collection

according

to

a

specified

schedule

as

described

above.

However,

for

FTP

and

TN3270

Server

Sessions

data,

the

data

are

provided

to

the

monitor

as

events

occur.

As

a

result,

FTP

and

TN3270

Server

Sessions

performance

metrics

are

updated

as

the

monitor

receives

notification

of

the

changes.

Each

monitor

can

collect

performance

data

from

the

system

where

it

is

installed.

In

addition,

monitors

can

be

configured

to

collect

performance

data

from

other

resources

with

IP

addresses

in

your

enterprise.

All

of

this

data

is

stored

in

the

central

database,

making

it

accessible

from

the

Tivoli

Monitoring

for

Network

Performance

user

interface.

To

summarize,

the

network

systems

programmer

determines:

v

Which

resources

to

monitor

v

What

types

of

data

to

collect

v

How

often

to

collect

the

data

This

directly

affects

the

data

that

is

available

to

the

network

operator

when

viewing

the

Tivoli

Monitoring

for

Network

Performance

user

interface.

In

some

cases,

the

might

not

be

sufficient

for

a

particular

task.

For

example,

it

might

be

sufficient

to

specify

a

value

of

100

for

the

maximum

number

of

rows

of

that

are

displayed

in

a

However,

this

global

default

value

might

not

be

sufficient

when

displaying

data

on

the

view.

It

might

be

more

useful

to

display

a

maximum

200

rows

This

is

a

case

where

you

would

want

Working

with

performance

data

Tivoli

Monitoring

for

Network

Performance

enables

you

to

monitor

network

performance

by

providing

access

to

performance

data

which

is

collected

by

the

monitors

in

your

environment.

The

network

systems

programmer

determines

which

resources

to

monitor,

what

types

of

data

to

collect,

and

how

often

to

collect

the

data.

Operator

interaction

with

the

performance

data

occurs

in

the

work

area.

The

format

and

layout

presented

in

the

work

area

is

common

across

all

views

that

contain

data,

except

for

Run

Diagnostics

(see

“Running

diagnostics”

on

page

47),

View

Favorite

Graphs

(see

Figure

27

on

page

47),

and

Set

User

Preferences

(see

Chapter

4,

“Setting

user

preferences,”

on

page

19).

When

you

select

a

task

from

the

portfolio,

the

data

are

displayed

in

the

work

area.

The

first

view

that

is

displayed

is

a

high-level

view

that

contains

several

performance

metrics.

The

performance

metrics

are

displayed

in

table

format

where

each

row

in

the

table

represents

a

unique

resource,

connection

or

session

being

monitored.

The

data

displayed

on

the

high-level

views

represent

the

most

recent

data

collected.

Each

view

contains

data

for

each

of

the

systems

being

monitored.

Because

the

collection

criteria

could

be

different

on

each

of

the

monitored

systems,

the

time

stamps

and

frequency

of

data

collection

for

each

row

in

the

table

will

most

likely

differ.

When

performing

problem

determination,

it

is

often

necessary

to

examine

performance

data

from

previous

collection

periods.

You

can

access

data

from

previous

collection

periods

using

the

Details

and

Graphing

functions.

These

functions

are

described

in

Chapter

6,

“Problem

determination

tools,”

on

page

37.

The

remainder

of

this

chapter

describes

the

common

components

of

the

high-level

views

and

how

you

can

manipulate

the

data

tables.

Figure

Thresholds

Crossed

The

monitor

collects

a

number

of

performance

metrics

for

each

resource,

connection

or

session

being

monitored.

The

network

systems

programmer

can

optionally

assign

a

threshold

value

to

one

or

more

of

these

metrics.

Specifying

a

threshold

value

instructs

Tivoli

for

Network

Performance

to

alert

the

operator

of

a

possible

performance

problem

when

the

value

of

a

metric

crosses

its

threshold

value.

The

Thresholds

Crossed

column

contains

the

number

of

metrics

whose

thresholds

have

been

crossed

for

each

resource,

connection

or

session

being

monitored.

The

Thresholds

Crossed

column

is

provided

on

all

views

that

contain

one

or

more

metrics

that

can

have

associated

threshold

values.

If

a

nonzero

value

is

displayed

in

this

column,

a

red

icon

is

to

these

common

fields,

each

more

fields

that

uniquely

identify

the

resource,

For

example,

in

Problem

determination

tools

When

configuring

the

monitors,

the

network

systems

programmer

determines

which

resources

to

monitor,

what

types

of

data

to

collect,

and

how

often

to

collect

it.

The

network

systems

programmer

can

optionally

assign

a

threshold

value

to

one

or

more

performance

metrics.

The

monitor

compares

each

piece

of

data

that

it

collects

to

its

associated

threshold

value

to

determine

if

the

threshold

has

been

crossed.

If

the

threshold

has

been

crossed,

the

data

are

flagged

in

the

database.

When

the

data

are

displayed

on

the

Tivoli

Monitoring

for

Network

Performance

user

interface,

a

red

error

indicator

is

displayed

next

to

the

value

of

each

metric

whose

threshold

has

been

crossed.

The

Thresholds

Crossed

column

contains

the

number

of

metrics

whose

thresholds

have

been

crossed

for

each

resource,

connection

or

session

being

monitored.

As

and

the

red

indicators.

The

red

indicator

placed

in

the

Output

field

indicates

that

the

threshold

value

for

this

metric

has

been

How

you

proceed

from

here

depends

on

the

operational

protocol

that

is

provided

by

your

network

systems

programmer

and

network

administrator.

Depending

on

the

nature

of

the

problem,

you

might

resolve

the

problem

by

completing

a

predefined

set

of

instructions

that

relate

to

a

set

of

specific

network

problems.

Other

situations

can

require

that

you

gather

more

data

related

to

the

problem.

In

this

case,

you

might

have

to

gather

associated

data

from

previous

collection

periods

or

from

other

resources,

connections

or

sessions

being

monitored

on

this

system.

In

other

cases,

it

is

sometimes

useful

to

compare

the

performance

metrics

from

this

system

to

performance

metrics

from

similar

systems

that

are

being

monitored

by

Tivoli

Monitoring

for

Network

Performance.

Regardless

of

the

situation,

Tivoli

Monitoring

for

Network

Performance

provides

a

set

of

problem

determination

and

data

gathering

tools

that

help

you

resolve

performance

problems

before

they

become

critical.

You

can

use

these

tools

to

gather

data

and

analyze

the

health

of

your

system

at

any

time.

The

ability

to

display

performance

data

from

previous

time

intervals

(collection

periods)

can

help

you

determine

when

and

how

a

performance

problem

began

to

surface.

This

information

can

be

very

helpful

when

trying

to

resolve

performance

problems

and

more

importantly,

avoid

them

in

the

future.

Displaying

more

detail

The

Details

view

provides

a

quick

glance

at

the

three

most

recent

performance

values

that

a

monitor

has

collected

from

a

resource,

connection,

or

session

being

monitored.

You

can

display

the

Details

view

by

selecting

a

row

in

the

table

and

clicking

Details.

The

Details

button

is

available

when

one

and

only

one

row

in

the

table

is

selected.

In

the

case

where

red

error

indicators

are

displayed,

you

can

click

the

number

displayed

in

the

Thresholds

Crossed

column

or

the

value

of

the

metric

whose

threshold

has

been

crossed

to

go

directly

to

the

Details

view.

Assume

for

this

example

that

you

have

clicked

on

the

in

the

is

represented

as

a

values

were

specified

by

the

network

programmer,

they

are

displayed

here

along

with

the

monitors

can

be

received

by

the

IBM

Tivoli

Enterprise

Console

server,

IBM

Tivoli

NetView

for

z/OS,

and

any

application

that

can

receive

Event

Integration

Facility

(EIF)

events.

The

networks

systems

programmer

determines

the

threshold

and

rearm

values

for

each

metric

being

monitored

and

whether

events

are

generated

when

thresholds

are

crossed.

Products

such

as

the

IBM

Tivoli

Enterprise

Console

are

an

effective

means

for

monitoring

the

performance

of

your

network.

As

described

in

Chapter

6,

“Problem

determination

tools,”

on

page

37,

the

procedure

you

will

follow

when

you

receive

events

depends

on

the

operational

protocol

defined

by

your

network

systems

programmer

and

network

administrator.

For

example,

you

might

be

provided

with

a

set

of

instructions

to

follow

that

explain

how

to

resolve

a

problem

when

a

specific

event

is

generated.

Or,

when

you

receive

a

particular

event,

you

might

be

required

to

gather

additional

data

for

the

network

systems

programmer.

Regardless

of

the

operational

protocol,

events

are

a

useful

source

of

information

for

problem

determination.

There

are

two

classes

for

the

events

that

Tivoli

Monitoring

for

Network

Performance

generates:

v

ITMNP_ThresholdExceeded

(used

when

an

event

is

generated

because

a

threshold

has

been

crossed)

v

ITMNP_ThresholdRearmed

(used

when

an

event

is

generated

because

a

rearm

value

has

been

crossed)

Table

2

on

page

124

contains

the

field

descriptions

of

the

events

that

are

generated

by

Tivoli

Monitoring

for

Network

Performance.

Both

event

classes

contain

the

same

fields

(slots).

The

values

in

these

fields

are

displayed

in

English

only.

Field

Descriptions

for

Events

Field

(slot)

Type

Description

adapter_host

STRING

The

host

name

of

the

monitor

that

sent

the

event.

adapter_ip

STRING

The

IP

address

of

the

monitor

that

sent

the

event.

field_name

STRING

The

name

of

the

field

within

a

measurement

that

exceeded

a

set

threshold.

field_value

STRING

The

value

of

the

field

that

exceeded

a

threshold.

hostname

STRING

The

host

name

of

the

target

system

(the

system

to

which

this

event

applies.)

Usually,

this

is

one

of

the

IP

stacks

on

the

system

on

which

the

monitor

is

running

but

it

can

also

refer

to

a

remote

host

in

the

case

of

availability

and

response

time

or

SNMP

Monitor

data.

monitor_host

STRING

The

value

of

monitor_host

name

from

itmnp.properties.

This

may

differ

from

adapter_host

in

a

NAT

environment

(that

is,

the

WAS

system

may

recognize

the

monitor

by

a

host

name

that

is

different

than

the

one

by

which

the

monitor

recognizes

itself.)

msg

STRING

This

is

a

textual

description

of

the

event

and

is

displayed

on

the

event

summary

screens

in

both

TEC

and

NPDA’s

event

viewer.

It

states

the

name

of

the

target

system,

whether

this

is

a

threshold

trip

or

a

threshold

rearm

event,

the

name

of

the

offending

field

within

the

measurement,

the

value

of

that

field,

and

the

threshold

type

and

value.

msmt_details

STRING

The

entire

contents

of

the

measurement

that

triggered

this

event.

The

system

networks

programmer

can

set

a

threshold

for

each

of

the

measurements

written

to

the

database.

Typically,

the

user

needs

the

values

contained

in

the

measurement

to

correlate

the

red

error

indicator

(x)

that

is

displayed

on

the

Tivoli

Monitoring

for

Network

Performance

console

with

an

event.

As

an

example,

an

event

could

be

sent

because

bandwidth

use

was

greater

than

50

percent,

but

without

the

z/OS

interface

name,

the

user

would

not

know

which

z/OS

interface

this

event

pertains

to.

msmt_id

STRING

Measurement

ID

of

the

measurement

that

triggered

this

event.

All

of

the

measurements

written

to

the

database

have

a

corresponding

measurement

ID.

This

value

can

be

used

to

find

the

corresponding

measurement

in

the

database.

origin

STRING

IP

address

of

the

target

system.

severity

WARNING

or

HARMLESS

The

severity

of

the

event.

Threshold-exceed

events

have

a

severity

of

WARNING,

while

rearm

events

are

HARMLESS.

source

STRING

The

product

that

generated

the

event.

Always

ITMNP

for

these

events.

sub_source

STRING

The

subsystem

within

the

product

that

generated

the

event.

Always

NET

for

these

events.

thold_id

STRING

Threshold

ID

for

the

threshold

descriptor

in

the

database.

This

can

be

used

to

find

the

threshold

definition

in

the

database

and

also

to

correlate

threshold

tripped

events

with

corresponding

threshold

rearm

events.

timestamp

STRING

The

time

stamp

of

the

measurement

that

triggered

this

event.
