Diagnostics - Traffic Analyzer

Applications communicate with the database server by exchanging SQL queries and responses. The ScaleArc Traffic Analyzer tool helps you analyze the SQL traffic captured on the wire between your application and database server. It gives you a profile of the traffic pattern, which can then be used to fine-tune the ScaleArc appliance for optimum performance. 

The Traffic Analyzer feature is divided into two functional modules:

Traffic Capture 

Follow these steps to use the Traffic Capture utility for capturing network-level SQL traffic passing through the ScaleArc appliance for analysis. 

  1. On the ScaleArc dashboard click on LIVE MONITOR > Diagnostics > Traffic Analyzer


  2. Click TRAFFIC CAPTURE to select the parameters for capturing network traffic. 
  3. Configure General Options for capturing traffic, starting by choosing a Mode to capture the traffic.


    Configure parameters as follows:



    Default/user input

    Mode Mode to capture traffic. Select either Cluster or Host and Port. Choose Cluster or Host and Port. 
    Cluster The cluster name. Select a cluster.
    Host The hostname. Enter hostname.
    TCP port The TCP port. Enter the TCP port number for which you want to capture the data.
    Analyze after capture Enable/disable traffic analysis of the captured traffic data. Use the toggle to ENABLE/DISABLE traffic analysis on captured data traffic.
    Start Begin capturing the traffic data.  
  4. Click on Capture Scheduling Options to select the preferred scheduling method, which can either be by Duration in seconds or by Number of files.


    If you select Capture Duration then configure the following parameters:



    Capture Duration (sec) Define the maximum duration of the traffic capture to record data in seconds (1-86,400). The creation of the tcpdump file is stopped automatically once the maximum duration has been reached even if the size of the file specified has not been reached.
    Size of File (MB) Define the maximum size (MB) of the tcpdump file captured. Each file that is captured is limited to the size specified here.     

    If you select Number of Files then configure the following parameters:




    Number of Files Enter the number of files to be captured (1-100). The creation of the tcpdump files is stopped automatically once the maximum number of files has been reached.
    Size of File (MB) Define the maximum size (MB) of the tcpdump file captured. The creation of the tcpdump file is stopped automatically once the maximum file size has been reached.
  5. Click on Capture Advanced Options to configure additional parameters.




    Start Delay (Sec) Enter the duration in seconds (1-3600) before the traffic capturing utility begins recording data.
    Advanced traffic capture options Enter advanced options for the traffic utility to record data. Refer to the TCPDUMP man page for information on configuring advanced traffic capture options.
    SQL ports for analysis (1-65535) Enter additional comma-separated ports for analysis.


    Traffic Analysis 

    Use the TRAFFIC ANALYSIS option to analyze and generate reports from the captured data,


    Configure parameters as follows:



    Select PCAP file Upload PCAP (.pcap, .cap, etc) file for analysis.
    SQL Ports for Analysis
    Enter additional comma-separated ports (1-65535) for analysis.

    Analyzing Records  

    Once the file is analyzed a record is created.




    Default/user input

    System Storage The system storage used and available.  
    Refresh Refreshes the list of records. Click to refresh the record list.
    Delete ALL Deletes all the reports generated. Click to delete all the reports.
    ID The number associated with a report.  
    Date The date and time the report was created.  
    Status The status of the record.  
    Size The size of the record.  
    Mode Displays the mode used to capture the traffic, either cluster name or host IP and port number.  
    Action Icons provide options to analyze, download, delete and view the report. Click on an icon to perform the related action.

    View a Report  

    Click on the view icon (eye) then select a file to open from the drop-down list.


Click on Traffic Analyzer Report details for more information on the report generated by the traffic analyzer tool.

Traffic Analyzer Report details 

The Traffic Analyzer Report displays the statistical summary of SQL traffic such as read/write queries, queries in transactions, SQL version, etc. Additional information on SSL connections, MySQL traffic session count, traffic bifurcation in transactions can also be viewed.
