  • Aqsa and Saba are working together. Their goal is focusing on visualization of PingER historical data using warehouse.  The idea is to develop a warehouse in UAF university and make it publicly available. They are 50-60% done with setting up a Hadoop cluster with 3 nodes, 1 master, 2 slaves. She is currently working on importing the PingER data into hdfs on the  cluster. they have run some Impala queries on the data and are working on visualization
    • Topic: visualization on pingER data (email from Aqsa and Response from Renan)
      I have studied the google charts as visualization tools but here are some points need to be discussed.
      1. The idea of applying visualization on Data warehouse (Impala query results) does not seem to be so useful because Data warehouse contains static data and visualization charts will also remains static and need to be updated with the time.

      Yes, it needs to be updated with the time. My suggestion is to transform PingER data into data to be inserted into the data warehouse. Myself and some other Brazilian students have developed codes to do this. Such process should occur at least once a day to keep the data warehouse updated daily. This has never been done by any of us.

      2. Google charts API cannot integrate with Impala As Impala is hadoop distributed Big Data supported database Google can only integrate with flat files or flat databases like Mysql. 

      If Google charts API can only read flat files (e.g., CSV files), it is trivial to save a database query result as a CSV flat file that would be consumed by Google charts.  Can Google charts generate a plot dynamically after reading a just-created CSV file? 
      Is using a different data visualization library (e.g., D3 https://d3js.org/ ) an option?

    • Aqsa and  team members are working on

    Handling Missing Data in PingER by using Artificial Intelligence. He has executed some Java queries and looking at parallel scientific workflow management using SciCumulus.
  • Sara Masood is working on a PingER Internet Performance Monitoring Agent On Android Device. There has been a discussion to pin down more closely what is needed, i.e. a PingER Measurement Agent running on an Android making measurements to the Beacons, and the ability to upload the data nightly. We held a  skype group meeting with Topher, Sara, Saqib, Bebo and Les to move forward. See 20160331 Meeting on PingER/Android, also see Discussion on porting PingER to Android. She has what she needs for now.

Project on Internet performance has been accepted, but no funding yet.

UTM 

Saqib's old supervisor  agreed to appoint a master student to take of PingER in UTM. Saqib has emailed  3/9/2016, no progress 4/6/2016, no progress 5/18/2016. Any progress 6/22/2016.

Muhammad Anas Abrar provided an update 6/19/2016: 
pingerqta.pern.edu.pk (DNS resolves to 121.52.157.157) are asking to change the IP to 121.52.157.148, 
  • Currently it does not respond to ping pingerqta.pern.edu.pk 
  • Ping 121.52.157.148, responds
  • http://121.52.157.148/ Apache responds. http://121.52.157.148//cgi-bin/ping_data.pl? responds (albeit very slowly) with Get Ping Data from sharedw228.b2bhosting.net  
    • This is a funny hostname. It comes from the system response to the perl commands:

      • use Net::Domain qw(hostname hostfqdn hostdomain);
        my $hostname = hostfqdn();

  • Also there is data. 
  • The following needs to reflect the new IP address at 121.52.157.148
    • Output from: /bin/cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1		localhost.localdomain localhost
121.52.157.157   pingerqta.pern.edu.pk
  • It is very easy to change the IP address once the Measurement Agent is up and running and responding, in fact the PingER meta data at SLAC was changed in February 2015. Howeer the DNS still points to:

    [cottrell@pinger ~]$ nslookup pingerqta.pern.edu.pk

    Server:  134.79.111.111

    Address: 134.79.111.111#53

Following hosts are down and not responsive. Nodes were contacted many times for identifying their issues. i.e turn on their pinGER Computers but never responded well.

Where as following is the list of Node that are now working:
The following are close to working:

    • creating Data warehouse and we are very close to complete this. Here are some updates.

      • Tehseen qureshi has transformed the pingER text files into binaries and soon he will be able to get CSV files.

      • Saba is working on defining a 4 node cluster.
      • Aqsa has uploaded some sample CSV files on HDFS and run Impala queries as i will get the actual CSV from tehseen these steps are also will be completed

    • Visualization Status 

    • Aqsa has 

      drawn a line chart and bar chart on the data of sample CSV file and i am exploring some more charts to be drawn by using Google API's.

  • Sara Masood:
    1. pingER  monitoring host on android . I am using perl-android-apk Interpreter to run pearl on android.. it include execution of  3 perl scripts

      1. getdata.pl

      2. ping_data.pl

      3. pinger2.pl

    2. Resources Required

      1. i need ping_data.pl script file and getdata.pl script file.

      2. Joao will provide them via anonymous ftp.

    3. Research Status

      • Perl-android-interpreter is not executing .pl file mainly because old Perl version (Perl 5.10) which is not comparable with android lollipop 5.0 version, i am compilingPerl .5.22.0 for android ,it may solve issue. 

Project on Internet performance has not received funding.

Saqib will proceed to install Pinger in UAF Pakistan

UTM 

Saqib's old supervisor  agreed to appoint a master student to take of PingER in UTM. Saqib has emailed  3/9/2016, no progress 4/6/2016, no progress 5/18/2016. 

1.     Currently, Pinger server is located in the faculty server room. Recently, faculty has closed the Server room. Now we have to move it to the University Central Server Room. For this we need support from Prof Johari and Prof Abdul Hanan.

2.     For the M.Sc. student in UTM we have to request again to Prof Hanan and Prof Asri and we need support from Prof Johari.

The following are close to working:

* This host was noted at the 3/9/2016 meeting as being down for the last 30 days.

+ Not seen in June 2016

Les proposes:

  • Give up (i.e. remove from Monitoring node table by setting Projecttype to D (for Disabled))  on non-responsive hosts not working since 3/9/2016.
  • I would not oppose extending thsi to all non-responsive, non-working hosts.
  • Focus on the close to working hosts

 

PingER at SLAC

Joao making the data on FTP to be up-to-dtaedate. 

Also has a 4 node cluster with Cloudera manager for Hadoop, Next step are to get impala working for queries.

 Working on the following hosts to be able to gather data
