CNM Portal Management

• Portal management, including InfoVista access, is
  administered by the GTA Network Management Team.
• This includes
• Establishing new users
• Resolving user issues
• Changing user entitlements (these define
  permissions)
• For a new portal ID, email mplsportalsupport_at_gta.g
  a.gov
• To report trouble, call the Command Center at
  [phone].

5
System Requirements

• Some elements of the CNM Portal are more
  intensive and may overload your system depending
  on your processor, memory, operating system, and
  other software updates. A 1Ghz CPU with 512mb
  of RAM (or more) is preferable.
• If you experience significant lag or long wait
  times, try closing email and other applications.
• Ensure that you have the latest Java update
  updating Java can make a tremendous difference in
  using InfoVista, since all of the reports and
  functions are Java-based.

6
System Requirements

• Current Java files are crucial to the operation
  of InfoVista.
• New Java updates are released frequently.
• Use this website to check what version of Java
  you have

16
CPE tab Router Performance Report
The CPE tab page contains several types of
information. By breaking it into sections, we can
examine each part of it separately.
First, lets take a look at the Router
Performance Pane.
Youve already previewed each of the tabs with an
overview of their functionality. The time
navigator and the device navigator are used to
designate the time period and the target device
for a report. They will be covered in more detail
shortly. For now, lets remove all of those so
we can get a better look at each of the CPE panes
containing devices and metrics.
17
CPE tab Router Performance Report
The default Router Performance Report pane
displays the top 10 CPE devices measured by CPU
usage.
Click on any device name for more detailed
information on that CPE. Well select
GTAGDOC2005. The report is generated, and it
shows hourly CPU and memory usage over a 1 day
period. Well look more into understanding
reports later, but this covers the very basics of
generating a performance report on a CPE device.
Memory usage is also displayed. These two
metrics provide a snapshot of the daily system
load.
18
CPE tab WAN Interface Report
The WAN Interface Report lists metrics on each
interface, including
In Avg Traffic Average amount of incoming
traffic on the selected circuit
Out Avg Traffic Average amount of outgoing
traffic on the selected circuit
Out Peak Traffic Peak amount of outgoing traffic
on the selected circuit
In Peak Traffic Peak amount of incoming traffic
on the selected circuit
Speed The highest amount of traffic throughput
in megabytes per second
Availability The percentage of time that the WAN
interface is available
Saturation The percentage of maximum
traffic-handling capacity utilized.
Error Out Percentage of errors in outgoing
traffic for the day
Error In Percentage of errors in incoming
traffic for the day
Since the information is a bit crowded and could
be difficult to read, click the FULL SCREEN link
at the bottom.
IN PEAK is the highest amount of traffic on this
interface. This is important with congestion or
bogging down issues!
19
CPE tab WAN Interface Report
Time Navigator functionality is available to
easily change the date or duration of these
reports.
Report graphs are generated for each metric.
Each report displays time across the bottom and
performance on the left side.
To use, save, or email these reports, click the
Formats menu and select the desired output format
PDF, text , excel, or XML file.
Click on any device name to generate a report
page.
More on this in Use Your Report page later in
this presentation
20
CPE tab Frame Relay pane
The Frame Relay pane indicates a daily average
for inbound and outbound traffic, measured in
percent according to total capacity.
Click on the device name to generate a
report. GTADTAE4001 shows in inbound average of
41.3 percent for the day. The graph report
indicates much more detail, showing actual
inbound traffic volume from 10 to 90 for that
day.
21
CPE Top Bottom tab
The CPU devices are rated on a daily average of
CPU usage measured in percent.
The CPE Top Bottom tab displays a quick
reference listing of the top and bottom 10 CPE
devices rated by CPU and memory usage.
Daily CPU usage in percentage
Daily Memory usage in percentage
Top 10 devices by CPU usage
Bottom 10 devices by CPU usage
If you have fewer than 10 sites, all of them will
be displayed on the top bottom tabs
22
CPE Top Bottom tab
The reporting period may be modified as desired
using the time navigator along the top.
CPU usage in percent
This is an hourly graph, but it can be modified
to display daily or longer time periods.
Metrics are displayed for the device showing CPU
and memory utilization.
t i m e i n h o u r s
Similar to the CPE tab, select any device to see
more details on usage metrics for that device.
23
Access tab
The Access tab contains metrics displaying
latency, availability, jitter, and packet loss
for the access lines routes.

• CoS categories include
• BE Best Effort
• PB Priority Business
• IA Interactive
• RT Real Time

The BE annotation after the site name indicates
the Class of Service (CoS) level. BE is Best
Effort.
24
Access tab
As with the CPE tab, you can double-click any
level to update the right pane for that region,
agency or site. Select any line to generate
reports for that instance.
25
Access Top Bottom tab
The Access Top Bottom tab contains a listing of
the top 10 and bottom 10 access routes based on
Latency metrics.
If you have fewer than 10 sites, all of them will
be displayed on the top bottom tabs
26
Access Top Bottom tab
As with the Access tab, select the device name to
generate a graphic report.
This list displays the bottom 10 Access lines for
usage (average) in the time shown.
This list displays the top 10 Access lines for
usage during the time period shown.
This list displays the Packet Delivery percentage
during the same time period.
This list displays the Availability percentage
during the same time period.
This lists the Latency (average) for the same
time period shown above.
This list displays the Availability percentage
during the same time period.
This lists Packet Delivery (average) for the same
time period shown above.
This lists the Latency (average) for the same
time period shown above.
27
Class of Service (CoS)

• On both the Access tab and on the Access Top
  Bottom tab, you may have noticed the CoS
  abbreviations after the route identifier.
• The CoS abbreviations indicate
• BE Best effort
• PB Priority business
• IA Interactive
• RT Real time

28
Class of Service (CoS)

• Class of Service (CoS) describes 4 levels that
  indicate service priority. The customer
  subscribes to a CoS level depending on their
  business needs and requirements.
• Best effort
• Business priority
• Interactive
• Real time
• As long as traffic congestion is not a problem,
  all 4 levels will move data traffic freely along
  the network.

Lowest priority Highest priority
Whenever traffic slows due to increased demand or
a service degradation, traffic priority is given
to the higher CoS level.
Best Effort
Business Priority
Interactive
Real Time
29
Class of Service (CoS)

• So it works like this. Assuming no congestion or
  latency issues, all traffic will be transmitted
  over the network normally.
• Best effort
• Business priority
• Interactive
• Real time
• If something were to slow the network, traffic in
  the lowest priority level would wait while the
  higher priorities are transmitted.
• If traffic flow is still impeded, the next level
  would be delayed.
• If traffic flow is not improved, the next level
  would then be delayed. At this point, Real Time
  would be the only level being transmitted.
• As soon as all Real Time traffic is transmitted,
  the next lower priority (Interactive) would be
  sent, and then the next lower priority.
• Once the congestion issue is resolved, all
  traffic would begin flowing normally again.

30
Time Navigator
Youll need the Time Navigator and the Device
Navigator in order to locate the correct
information prior to generating a report.

• Both the CPE tab and the Access tab contain the
  Time Navigator.
• The final reports and graphs also contain Time
  Navigator functionality.

The Time Navigator designates the date for any
generated reports, and also specifies the time
period length for the report.
31
Time Navigator
The purpose of the Time Navigator is to specify
the date and time period prior to generating a
performance report. The report date and time may
be specified using these controls
1

• Navigation arrows
• Time period
• Calendar icon
• Time interval menu
• GO button

The navigation arrows will increase or decrease
the time by the amount displayed in the time
interval menu. If the time interval menu is set
to Daily, each arrow click will change the date
by one day. If the time interval menu is set to
Monthly, each arrow click will change that date
by one month. Each arrow click will ALSO refresh
the display if a graph has already been
generated, slowing the application considerably
while waiting to reload it.
The GO button is used to generate the report
after entering a date directly into the field via
keyboard. If the time period is altered using the
navigation arrows or the calendar function,
InfoVista will begin to create the report when
the new date is selected.
The calendar function is convenient for adjusting
the reporting period by larger amounts. Click
the calendar icon, use the left right arrows at
the top to display the desired month, and then
click on the desired date to generate the report.
The time period may be directly entered into this
field using the keyboard, or it may be changed
with the navigation arrows to move it forward or
back by the interval shown, or a new date may be
selected using the calendar function. Once set,
any generated report will contain data for this
time period until the time navigator is reset or
modified again.
The time interval menu selects the time period
for a report whether it will cover an hour, a
day, or a month time period. As the time
interval menu is selected, the time period on the
left will change to reflect the new time
increment.
32
Time Navigator
As the time period is selected on the right side,
the time period field on the left side will
change to match that time increment.

• By selecting Monthly, InfoVista will change the
  left field again to allow for monthly choices.
• InfoVista has 4 time periods
• Hourly
• Daily
• Weekly
• Monthly

Within the Time Navigator, some fields will
change as you make your selections.
Lets look through the time period options, and
watch the time/date field on the left side as it
changes.
Whether we want to look at performance metrics
for yesterday, last week, or last month, the Time
Navigator is the first stop to select the date
for reporting metrics.
The default time period is Daily. The date field
to the left displays the date, and allows the
date to be entered or altered. If we click the
time period menu and change it to Weekly, the
date field on the left will change to allow
selection by weeks.
33
Device Navigator

• Just as the Time Navigator selects the time
  period to examine metrics or create a report, the
  Device Navigator selects the target device or
  access route for any generated performance
  reports.

• Both the CPE tab and the Access tab contain the
  Device Navigator.

34
Device Navigator
If youre familiar with Windows Explorer, youll
notice that the Device Navigator is similar in
appearance and in function. Click on to view
additional detail within an agency, and click on
to close or hide it. Just like in Windows
Explorer, use the tree on the left pane to
navigate or drill down to the desired location or
device.
Select the symbol to view devices below.
Select the next symbol to view additional
devices.
and select the desired target device.
35
Device Navigator
Lets look closely at GTAGDOC1001 in the Device
Navigator. The target site location 001 shows a
(4) after it. This indicates that there are 4
devices or interfaces at that location. Click on
001 (4) and you can see a list showing those
device or interface names in the lower section.
The CPE router is always listed first, if there
is one. In this case, it is followed by an ATM
interface and 2 virtual access lines.
Double-click on any agency level or device name
and the metrics panes on the right side will be
updated for that selected agency level or device
36
Naming Convention
GTA
GDOC
1
003
The device name will start with GTA as the first
three letters
So it works like this
Each device requires a unique name to identify it
on the network
State Level (GTA)
GTA
We will examine GTAGDOC1003 and see how the name
is derived
The next four letters are derived from the Agency
name
Agency (GDOC)
GDOC
GTA Region (1)
1
The next single number indicates the GTA Region
Site (003)
003
The number after the site location 003, indicates
the number of routes or devices at that location.
That means that 003(2) has two managed routes
or devices at that location that we will be able
to monitor using the CNMP applications.
The last three numbers indicate the specific Site
location (003)
37
What Do All These Metrics Mean To Me?

• Latency The time delay for a packet of data to
  get from one point to another point.
• Packet Loss The percentage of packets sent that
  will be lost (out of 100) in transmission.
• Jitter The variation in the time between
  packets arriving critical in VoIP applications,
  but less important for email, data, etc.

Latency is typically expressed in milliseconds,
(ms) and measures the transmission time to travel
to the destination and return. Contributors to
latency include the transmission medium (wire,
fiber, etc.), packet size, hardware involved, and
other variables.
Packet loss may be an indication of network
congestion or other factors.
Jitter is frequently caused by packet
transmission delays.
P I N G
Latency shown here is 72 milliseconds
38
Understanding Metrics Indicators

• In InfoVista, colored indicators make it quick
  and easy to recognize problems, changes, or
  alerts at a glance.
• Green indicates that the system is functioning
  well and is within the expected parameters.
• Orange indicates a reading just out of range
  frequently a device or interface may be going
  down or coming back up.
• Red indicates a reading way out of range
  possibly a device or interface that is
  overloaded, non-functional or not responding.
• How quickly could you spot a problem area on
  this page?

39
Quick Report

• The right-click menu allows quick and easy access
  to regional or site reports, directly from the
  Device Manager
• Right-click to select any region, site, or
  device, and then select the Router Performance
  report to update the metrics in the right pane
  with current data.

The right pane is updated with metrics from DFCS
Region 1.
40
Performance Reports

• InfoVista reports are labeled with captions
  clearly stating what type of data is being
  displayed in each report.

Indication of Report Type
41
Performance Reports

• While each of these reports may appear different,
  they are all interpreted in much the same manner.
• Performance is measured up the left side of the
  graph,

while time (GMT) is indicated across the bottom.
To convert time from GMT to EST, subtract 5
hours. That means 1000 indicated was really 5
AM local time.
Subtract 4 hours for daylight savings time
42
Performance Reports

• This graph starts at 0000, or midnight (GMT),
  and the CPU usage is at 16.
• As time progresses, the CPU usage percentage
  drops, and then later begins to climb again.

Subtracting 5 hours from the GMT time shown (to
EST) shows an increase in activity from 5 am to 5
pm.
43
Time Conversion
Remember, all reports are displayed in Greenwich
Mean Time (GMT). This means you have to
subtract 5 hours for Eastern Standard Time (EST),
or 4 hours for Eastern Daylight Savings Time (EDT
is Spring Summer).
If you notice any spikes or unusual activity at
odd hours, this could indicate a network security
problem Time to notify someone!!
44
Time Conversion
This table displays GMT, EST, and EDT time
differences compared to normal clock time.
This line indicates 0900 on the report.
InfoVista reports are GMT, so start with the GMT
column.
0900 is 9 am, but thats still in GMT. Subtract
5 hours for EST (4 am), or Subtract 4 hours for
daylight savings time (EDT) making it 5 am.
45
Performance Reports

• This report looks different, but is interpreted
  exactly the same way
• The time progression is across the bottom (24
  hours on this report)
• and the performance data is displayed on the
  left side.

So the lowest performance for this time period is
at 1800 GMT (1 PM EST) with 86 of the packets
successfully delivered.
46
Performance Metrics in Reports

• At the top of the report, there is a modified
  version of the Time Navigator.
• Once a report has been generated, you can modify
  the time period or report date forward or back to
  view adjacent dates and view performance metrics
  without closing the window and then starting
  over.
• We have the same navigation arrows, calendar, and
  GO button as the Time Navigator. There is also
  an additional field that defines the time span of
  the report- whether it covers a day, week, or
  longer.
• The timeline on this report is set to begin at
  noon and display 1 day of data.
• You can set the start date and time, set the
  duration, and then view a report on any time
  period for which data is available.

InfoVista reports span a period of time that is
indicated across the bottom of the graph.
Whether it measures hours, days, or weeks, older
time is on the left side, with more recent events
on the right side.
InfoVista reports have other things in common as
well... such as scalability.
If we examine the router performance report to
the right, CPU usage is being measured. The
highest value on the scale displayed along the
left side is 36. That indicates 36, although
the highest CPU spike actually reached only 32.
InfoVista sized the scale to fit the data. If
the CPU were to suddenly spike again and rise to
65, the next time this data is polled, InfoVista
would resize the graph so the new spike would
fit. The left side would be renumbered so it
would range above 65 at the top, and all the
data would still fit within the graph. The graph
will auto-adjust to fit the lowest and highest
values.
32
65
47
Customizing Report Results

• As the time period and the duration are modified,
  any new reports that are generated will display
  performance metrics for that new timeline.
• Here we can see reports with the timelines set
  to
• Hourly, covering a 1 day period
• Daily, covering a 1 week period
• Weekly, covering a 2 month period

This allows report time periods to be customized,
showing hour-by-hour performance peaks, or weeks
and even months at a time to see larger trends
that would not be readily visible while viewing
hourly or daily metrics.
48
Use This Report
10
Once a report has been generated, the controls
across the top of the report include the Formats
menu, which allows the report to be saved in a
variety of file types, and Time Navigator

InfoVista Summary

• As a network performance monitoring tool,
  InfoVista can help to diagnose network traffic
  issues by displaying CPE router and traffic
  statistics in out of a site that may be
  experiencing lag or latency issues.
• Available information spans time periods from
  monthly for understanding larger trends, all the
  way down to hourly for examining data traffic in
  and out of a specific location or along a
  specific route.
• A quick glance at InfoVista may be all you need
  to verify the congestion or latency issues that
  are being experienced.
