  • "Since we're still waiting on an account, at SLAC, I asked the student to explore another idea (which is quite relevant) proposed by Prof. Bebo “Creative visualization of PingER data, including rich interaction;”. He has already started looking at the possible attractive/interactive design, at the same time he is working to improve his programming skills."

  • "On the other hand, I am in the final stage of writing a case study on the Internet performance in ASEAN countries and its implication on the Socio-Economic Indexes. Will try to share with Dr.Les and Prof. Bebo soon to comment and get your advice on the publication possibility of the paper."

  • 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? 
    Tahseen is

    • 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.

Visualization ideas for PingER moved here 5/20/2016

 

  • One way of drilling down is via a map of all sites. Faisal Zahid put something together a couple of years ago. It is at http://www.slac.stanford.edu/comp/net/wan-mon/viper/pinger-coverage-gmap.html. It uses Google maps, allows pan and zoom, plus selection of type (measurement agent, beacon, target) of host to display. It also allows one to select a host (Search location),  mouse click on the balloon to find out more about the host, from there click on the sites web site, click on the country or region to get the relevant pingtable.pl information. The Visualize allows one to choose a measurement agent and a country and it draws coloured lines between the sites  to represent the metric choosen. This was very useful but parts of it are broken.  It would be great to fix or replace. It has some documentation.
  •  For plotting time series, Grafana looks very promising
  •  Updating the motion charts, adding newer data etc. would be most useful.  See http://www-iepm.slac.stanford.edu/pinger/pinger-metrics-motion-chart.html and http://www-iepm.slac.stanford.edu/pinger/explorer.html
  •  Enhance the selection Metrics, Ticks (see pingtable.pl)  to allow multiple metrics (min, avg, max RTT, loss, thrpughput, , MOS ..) to be plotted as a time series. 
  •  Enhanced selection remote hosts for selected tick, selected metric selected mutiple targets (pingtable.pl currently only allows one target), e.g. Once you have plot enable fitting the data to timelines (linear, exponential, power series)
  •  Map pf countries the world colored by metric allow selection of metric and for a particular year. with chosen MA,

    • Sara Massoud came up with ideas to improve the info put together by Amity

    • Sabah Massoumil working on Linked Open Data (please excuse spelling)

    • Aqsa Hameed working on big data/analysis of PingER data. The initial idea was to set up a big data/big analysis 

    • Aqsa Hameed has been working with Anjum to look at a project to create a Hadoop/Cloudera PingER warehouse to enable easier, more powerful access to PingER historical data. 

      • Thinking a bit on Aqsa her work appears to be related to the work done by Thiago on PingER warehouse using a cluster/Cloudera/HDFS/Impala earlier this year. In particular see the presentation at NETAPPS2015 (see https://confluence.slac.stanford.edu/download/attachments/123309267/NETAPPS_PRESENTATIONrevLuiza.pptx. Once the paper is published we can also provide her with that (Adib will let us know when this is OK). 

      •  Les emailed the relevant people to put them in contact with one another. It appears there is a lot of overlap between what Aqsa proposed as a Masters project and what Thiago has already done. However Thiago's system was mainly a proof of concept and not in production. We need to look at the next steps: Internet access, auto-updating of information in near realtime, production service, maintainable etc. With this in place one could really mine the data looking for all kinds of interesting correlations, clustering, event impacts, comparisons etc.

        • Given that such a warehouse is available, then the next step would be to automatically create queries that would produce in near real-time the plots we produce manually for the PingER annual reports.

        • Following this publish the data in RDF to tie in with the Southampton RDF web observatory repository (similar to what Renan did as a proof of concept).

        • Since Thiago's warehouse is only available at SLAC,  it may assist to get Aqsa an account at SLAC, alternatively Aqsa will need to set up a repository at here home base.

Ibrahim has setup distributed hadoop clusters. He has 2TB of disk space. Les has provided information on getting a subset of PingER data by anonymous ftp via ftp://ftp.slac.stanford.edu/users/cottrell.  It was put there last September. Information on how the data was put together is at https://confluence.slac.stanford.edu/display/IEPM/Archiving+PingER+data+by+tar+for+retrieval+by+anonymous+ftp. There is information on formatting etc at http://www-iepm.slac.stanford.edu/pinger/tools/retrievedata.html and some on the dataflows at https://confluence.slac.stanford.edu/display/IEPM/PingER+data+flow+at+SLAC. Renan at UFRJ has successfully used this data, he has also characterized the data in terms of bytes/metric per year etc.

Ibrahim has started downloading all zip files in the local machines. 6 weeks ago he downloaded 2 GB of Weather data to test his nodes cluster, he  wrote a simple Java program (Map, Reduce) to find the Average and it was working fine. 

Anjum reported that UM had experienced a TCP syn DOS attack prior to Mar 12th (when an IDS was put in place). It occurred mainly for several days before between the hours on noon- 2pm and 7-7 in the evening (Malaysia time). He suggested looking to see if PingER could spit the effect.  Ibrahim, Les and Anjum will look at. Les analyzed the data and sent it to Anjum

  • Hossein Javedani of UTM is interested in anomalous event detection with PingER data. Information on this is available at https://confluence.slac.stanford.edu/display/IEPM/Event+Detection. We have sent him a couple of papers and how to access the PingER data. Hossein and Badrul have been put in contact. Is there an update Badrul?

The Next step in funding is to go for bigger research funding, such as LRGS or eScience. Such proposals must lead to publications in high quality journals. They will need an infrastructure such as the one we are building. We can use the upcoming workshop (1 specific session) to brainstorm and come up with such proposal. We need to do some groundwork before that as well. Johari will take the lead in putting together 1/2 page descriptions of the potential research projects. 

...

  1. Need to identify a few key areas of research related to PingER Malaysia Initiative and this can be shared/publicized through the website. These might include using the infrastructure and data for: anomaly detection; correlation of performance across multiple routes; and for GeoLocation. Future projects as Les listed in Confluence here

  1. Future+Projects can also be a good start and also Bebo's suggestion. 
  2. Need to synchronize and share research proposals so as not to duplicate research works. how to share? Maybe not through the website, or maybe can create a member only section of the website to share sensitive data such as research proposal?

Anjum suggested Saqib,  Badrul and Johari put together a paper on user experiences with using the Internet in Malaysia as seen from Malaysian universities. In particular round trip time, losses, jitter, reliability, routing/peering, in particular anomalies, and the impact on VoIP, throughput etc.  It would be good to engage someone from MYREN.

17162/leveraging+pingER+big+data+with+a+modified+pingtable+for+event-correlation+and+clustering.docx. Ibrahim reports 7/15/2014 "I have spent the last few months trying to understand the concept of big data storage and its retrieval as well as the traditional approach of storing RDF data. I have integrated a single hadoop cluster in our cloud. but for this project we need multiple clusters, which I have already discussed with Dr. Badrul and he will provide me with big storage for the experiment." No Update 8/20/2014.

"I have come up with initial proposed solution model. This model consists of several parts. The upper parts of the Figure below shows the data source, in which PingER data will be convert into RDF format. Then the data pre-processor will take care of converting RDF/XML into N-triples serialization formats using N-triples convertor module. This N-triple file of an RDF graph will be as an input and stores the triples in storage as a key value pair using MapReduce jobs"

   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 compiling  Perl .5.22.0 for android ,it may solve issue.

Anjum suggested Saqib,  Badrul and Johari put together a paper on user experiences with using the Internet in Malaysia as seen from Malaysian universities. In particular round trip time, losses, jitter, reliability, routing/peering, in particular anomalies, and the impact on VoIP, throughput etc.  It would be good to engage someone from MYREN.

Ibrahim

Ibrahim Abaker  is planning to work on a topic initially entitled " leveraging pingER big data with a modified pingtable for event-correlation and clustering".  Ibrahim has a proposal, see https://confluence.slac.stanford.edu/download/attachments/17162/leveraging+pingER+big+data+with+a+modified+pingtable+for+event-correlation+and+clustering.docx. Ibrahim reports 7/15/2014 "I have spent the last few months trying to understand the concept of big data storage and its retrieval as well as the traditional approach of storing RDF data. I have integrated a single hadoop cluster in our cloud. but for this project we need multiple clusters, which I have already discussed with Dr. Badrul and he will provide me with big storage for the experiment." No Update 8/20/2014.

"I have come up with initial proposed solution model. This model consists of several parts. The upper parts of the Figure below shows the data source, in which PingER data will be convert into RDF format. Then the data pre-processor will take care of converting RDF/XML into N-triples serialization formats using N-triples convertor module. This N-triple file of an RDF graph will be as an input and stores the triples in storage as a key value pair using MapReduce jobs"
