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.

IBM
Tivoli
Monitoring
for
Network
Performance:
Operator
Guide
Chapter
1.
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.
The
environment
in
which
this
product
operates

IBM
Tivoli
Monitoring
for
Network
Performance:
Operator
Guide
As
shown
in
Figure
1
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
for
Network
Performance
Administrator
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
to
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
15
Chapter
1.
Introduction
3
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.

Setting
user
preferences
Tivoli
Monitoring
for
Network
Performance
provides
a
set
of
user
preferences
that
are
associated
with
each
user
name.
User
preferences
are
global
default
values
that
apply
to
the
data
displayed
on
all
views.
When
you
open
the
User
Preferences
for
the
first
time,
you
see
IBM-supplied
values
provided
for
each
of
the
user
preferences.
As
you
become
more
familiar
with
the
product,
you
can
modify
the
user
preferences
to
better
suit
your
needs.
You
can
view
or
modify
the
following
user
preferences
from

portfolio
by

In
some
cases,
the
global
default
values
might
not
be
sufficient
for
a
particular
task.
For
example,
it
might
be
sufficient
to
specify
a
global
default
value
of
100
for
the
maximum
number
of
rows
of
data
that
are
displayed
in
a
table.
However,
this
global
default
value
might
not
be
sufficient
when
displaying
data
on
the
Connection
Availability
and
Response
Time
view.
It
might
be
more
useful
to
display
a
maximum
of
200
rows
of
data
when
displaying
connection
data.
This
is
a
case
where
you
would
want
to
override
the
global
value
in
User
Preferences
with
a
value
specific
to
the
Connection
Availability
and
Response

view.
You
can
override
Auto

vary
significantly,
it
might
be
desirable
to
graph
the
metric
values
on
the

axis
using
a
logarithmic
scale.
A
logarithmic
scale
supports
only
metric
values
that
are
greater
than
zero
because
the
logarithmic
value
of
a
number
less
than
or

zero
is
undefined.
If
you
specify
a
logarithmic
scale,
any
metric
values
that
are
less
than
or
equal
to
zero
are
not
graphed.
Any
metric

that
approach
zero
may
not
be
graphed
depending
on
the
type
of

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.

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
Monitoring
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

that
task
is
displayed
in
the
work

are
displayed
in
table
format
where
each
row
in
the
table
represents
a
unique
resource,
connection,
or
session
being

on
page
35
explains
the
Select,
Thresholds
Crossed,
and
Collection

fields
which
are
common
to
all
views.
In
addition
to
these
common
fields,
each
view
contains
one
or
more
fields
that
uniquely
identify
the
resource,
connection
or
session
being
monitored.
For
example,
in
Figure
14
on
page
28,
the
resource
being
monitored
is
a
z/OS
TCP/IP
protocol
stack.
A
TCP/IP

stack
is
uniquely
defined
within
a

by
the
TCP/IP
job
name
and
the
fully

The
remaining
fields
in
the

for
each
TCP/IP
protocol
stack
being
monitored.

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

have
been
crossed
for
each

The

field
indicates
that
the
threshold

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

provides
a
quick
glance
at
the
three
most
recent
performance
values
that
a

has
collected
from
a

or
session
being
monitored.
You
can
display
the

they
are
displayed
here
along
with
the

Monitoring
network
performance
using
events
Events
generated
by
the
Tivoli
Monitoring
for
Network
Performance
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.
