It usually occurs after the implementation of a Cos Policy (Classes of Service) on the Wan, conveniently controlled by Alaloop portal.

 

The portal can also summarize the necessary information for managing a WaaS architecture :

1 / Mapping to optimize traffic (Data Source Netflow)

2 / Response time analysis (Data Source : WaE through NAM);

3/ Monitoring & alarms

4/ SLA reporting and planning

 

 

• New QUERIES for the CISCO switches
  
  

• Stacked COS graphs automatically available in the Custom graph tab

 

(*) Network Analysis Module

(**) Wide Area Application Services

3 / Monitoring

• Dynamic display of alarms in a cycle log entries display mode

  • Central zone of the Home Page ;

  • Optional display
    (can replace the homepage logo) ;

  • Designed for a control screen ;

  • Data displayed refreshed every min ;

  • Direct access to measurements by simple click on the bar chart.

 

4 / Dashboards

Dashboards menu gives access to 4 types of dashboards accessible by tabs. It is dynamically generated over any period preset or personalized by interactive calendars.

 

• Scoring : measurement score over the period based on thresholds (OK, Warning, Critical)

  

• Values : Max/Min/Avg values over the period;

• Graphs : measurement graph dashboards

  

• Custom graphs : graphs with multi measures analysis and multi scales
  

Remind: information provided in dashboards may vary depending on selected display mode (Technical / Executive)

 

Scoring dashboard (Scoring or SLA)

• Display of scores (OK, Warning , Critical) in % or time (radio button selection)

• Takes into account the maintenance periods

 

Values dashboard

• Min/Max/Avg values for measurement parameters over the period;

• Displayed measurement parameters are default ones ;

• This tool displays all measurement
  parameters over the period.

 

 

Graph dashboard

New options to sort graphs based on :

• • graph title,

  • measurement name,

  • target,

  • Operation/Query ( in technical display mode).

 

 

Custom graphs : check the improvements described page 3

• analysis graphs generally build through multiple measurements

  • graphs sorted by name

  • tool to design your own graph on line (*)

 

(*) accessible only in "technical" display mode.

 

Advanced Search : custom dashboards generation by multi-criteria research

 

1 / Tool accessible in the navigation tree by simple click (expandable area)

2 / Multi-criteria selection based on :

- current view within the tree (AlaloopNet_Without_COS)

- key fields to identify a measurement
(Measurement / Target / Details / Agent)

- state scores of measurement over the period
(ex : measures in Warning state > 20%)

- values for the result types of a measurement (example: network response time higher than 1 second)

Important notices :

• the search criteria may vary according to the active dashboard (scoring, values, graphs, custom graphs) and the dashboards display mode (Executive or Technical).

• All text fields provide autocompletion.

 

5 / Investigation tools

Portals have 5 investigation tools (the references indicate the new features)

• Measurement Graph : graph of the values (parameters) of a measurement (1)

• State Graph : graph of the states of a measurement (2)

• Values : values Min/Max/Avg of a measurement

• Measurement details : dashboards of the measurement values (3)

• State Logs : dashboards of the measurement states (3)

 

(1) Management of multiple scales in Y : allows to manage measurements with different units.

(2) Unknown state (measure not realized) in white in the legend.

(3) In the heading of the summaries, display of the maintenance periods if applicable.

 

6 / Custom Graph improvements

4 steps (the references indicate the new features)

1. selection of measurements/result types to be graphed ;

2. edition of the components of the graph (1) ;

3. name of the graph ;

4. generation of the graph (2).

 

(1) edition of the components of the graph

(2) Graph : multi-measurements / multi-scales

7 / Maps : investigation tools access

• 
  Investigation tools available by click upon the measurement point : the tools inherit the 24 hours period defined in the title of the graph (see example below)
  
  

• "Pop-up Graph" options
  (overflight of the measurement point)

  • Custom Graph Support

  • Selection of the result-type to graph.
    
    

• Management of the maps

  • Confirmation of deletion

  • Map background deletion : warning message if associated to a map.

 

 

 

 

 

 

8 / Reporting

• Maintenance Periods :

• Taking into account in all computations

• Optional appendix detailing the maintenance periods (SLA, States logs)

 

• • Running reports

• possible even if the data base is locked

• correct management of the dates displayed in the run, and the dates taken into account for the generation

• Empty dashboards : SLA or State empty logs are replaced by a message "no data to display"

 

• Edition :

• homogeneous management of the dates with the execution

• simplification of the report edition screen

• simple reorganization of the edition screens of the SLA/State logs (options of sorting/ layout )

• RTF export : cleaning of SLO appendices

 

 

 

9 / Netflow

Cross-analysis between aggregate data and raw data

 

• Analysis

1. 
   Investigate button : "Drill down" feature for the analysis of the traffic peaks.

2. drilling area is grayed out (data available) ;

3. slider to select traffic peak (period limited to one hour) ;

4. View Flows : detailed flows dashboard over the selected period ;

5. View Tops : selection of the Top report over the selected period (example : Top pairs who generated the peak)

 

 

• Flow search

1. slider to select traffic peak

2. button TOP REPORTS : generation of reports on the results of a "Flow Search"

3. Top Pairs generation : the IP address (x.y.z.211) is mainly behind the pic.

 

Measurement details resulting from NAM

 

Performance	Result_Type	Display
NAM_ART_SUMMARY (Server)
Response Time is the amount of time it takes a server to send the initial response to a client request as seen by the NAM.	Response Time avg Response Time min Response Time max	NAM_ART_AVG_RT NAM_ART_MIN_RT NAM_ART_MAX_RT
Number of TCP bytes sent from a server	Server Bytes	NAM_ART_SERVER_BYTES
AD is the time it takes a server application (for example, a web server application) to respond to a request. AD is the time between the client request arriving at the server application and the first response being returned by the application.	Application Delay avg Application Delay min Application Delay max	NAM_ART_AVG_AD NAM_ART_MIN_AD NAM_ART_MAX_AD
The network round trip (flight time) between a client and a server through the NAM switch or router. ND is equal to the sum of CND and SND. The network round trip (flight time) between a client and a server through the NAM switch or router. ND is equal to the sum of CND and SND. NAM measures the ND using TCP 3-way handshakes. If there are no new TCP connections made during the monitoring interval, this metric is not reported.	Network Delay avg Network Delay min Network Delay max	NAM_ART_AVG_ND NAM_ART_MIN_ND NAM_ART_MAX_ND
SND is the network round-trip time between a server and the NAM switch or router. In WAAS monitoring, CND from a Server data source represents the network RTT between the server and its core WAE.	Server Network Delay avg Server Network Delay min Server Network Delay max	NAM_ART_AVG_SND NAM_ART_MIN_SND NAM_ART_MAX_SND
TD is the total amount of time from the first packet of a client request until the client receives the first response packet from the application server. Total Delay (TD) is the sum of the Network Delay (ND) and the Application Delay (AD). Use TD with care because it is not measured directly and mixes the response time metric (SRT) with the connection metric (CND).	Total Delay avg Total Delay min Total Delay max	NAM_ART_AVG_TD NAM_ART_MIN_TD NAM_ART_MAX_TD
Total amount of time from the first packet of a client request until the client receives the final response packet from the server. TTT is a key indicator for detecting application performance anomalies.	Total Transaction Time avg Total Transaction Time min Total Transaction Time max	NAM_ART_AVG_TTT NAM_ART_MIN_TTT NAM_ART_MAX_TTT
NAM_ART (Server - Client)
Number of TCP bytes sent from a client during the monitoring interval.	Client Bytes	NAM_ART_CLIENT_BYTES
CND is the network round trip time (or flight time) between a client and the NAM switch or router.   In WAAS monitoring, CND from a WAE client data source represents the network RTT between the client and its edge WAE, while CND from the WAE server data source represents the WAN RTT (between the edge and core WAEs).	Client Network Delay avg Client Network Delay min Client Network Delay max	NAM_ART_AVG_CND NAM_ART_MIN_CND NAM_ART_MAX_CND
