Topher is here for a few days. He and Bebo discussed whether it would be better to use native Android tools rather than loading the perl interpreter and using it.
- Pro: easier for user, no need to load perl interpreter which may require missing skills, especially for a non technical user
- Con: the android version has to mimic pinger2.pl with all its logs, careful checking and specific format
To a large extent it depend on how we plan to use this. If the phones are just MAs in a fixed location then 1 is easier and probably sufficient. If this is intended to grow into a mobile application for general use then it needs to be 2.
We agreed that Sara Masood at UUM should continue pursuing using the standard pinger2.pl version running under the perl interpreter while Amity will try and put together a native android version.
We also briefly discussed how to get the data from the phone MA to the archive. The current method ping_data.pl requires a public IP address for the phone which mnay not exist if its is mobile. Getting the MA to put the data to the archive may raise some security issue for the archiver. We did ot come to a conclusion
UUM
From Adib:
Adib asked a student (Jaafrau) to explore “Creative visualization of PingER data, including rich interaction;”. He has come up with a good design, yet the development part needs a lot of work. Adib will ask him to upload his interface and share the link.
Adib has a student from

Bebo has set up a Github codebase as a new project. It contains the PingER MA (pinger2.pl and the traceroute/ping server). Anyone needs to sign up for a Github account (if you don't already have one), so you can be added as a project member.
- slac-pinger/pinger created by topherwhite. PingER project https://github.com/slac-pinger/pinger
- Now we have it we can share with Amity to check it works.
- Bebo reports that someone from Amity requested to be a member of the Android group.
UUM
From Adib:
"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."
- There is another student, (Jaafrau) has a design. Looking at visualization.
Adib has a student from Thailand who is working with Adib at UUM who may be interested in installaing a PIngER MA in Thailand. Adib will talk next week after exams to see if can get permissions. 8/3/2016: No update yet, as they have a long holiday in Thailand. Will try to contact him.
Adib has written a case study on the Internet performance in ASEAN countries and its implication on the Socio-Economic Indexes. It has been shared with Dr.Les and Prof. Bebo who have commented. We are looking for where to publish.

pinger.unimas.my is working again as of ~ June 18th,
No update 5/18/2016
also the traceroute server is working.
UAF (Saqib)
There are 4 students: Aqsa Hameed, Saba Muzamil, Tahseen and Sara Masood. T
Aqsa has completed her research work on "visualization on pingER data" and now working on to publish a conference paper. Here are few details of the research work.
The query results can be exported as CSV file. I use the CSV file of Query results from Impala to draw Line and Bar charts by using Google API.
She has created a Data warehouse on pingER data. First we transform the pingER text files into CSV files. Then i upload these CSV files on HDFS and populate Impala Tables and queries.
- Line and Bar charts are created on a webpage running or executed by localhost server. it can be updated as the query results varies.
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.
Aqsa has put together an abstract of a conference paper and has put together an abstract of a conference paper and submitted to "The 3rd IEEE/ACM International Conference on Big Data Science, Engineering and Applications (BDSEA 2016)" (http://computing.derby.ac.uk/bdcat2016/). "Applying Big Data Warehousing and Visualization Techniques on pingER Data", Aqsa Hameed, Dr. Saqib Ali, Dr. Les Cottrell and Bebo White, submitted to BDSEA 2016
- 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
Aqsa and team members are working on 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.
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?
- Sara Masood - pingER monitoring host on android .
- She is using perl-android-apk Interpreter to run perl on android. It includes execution of 3 perl scripts:
- getdata.pl, ping_data.pl, pinger2.pl
First step is to install pre-requisite i.e. lynx, perl, XML::Simple, make etc. However, she is having permission denied issue when she executes "make install” command at path usr/local/bin because it’s a read only file system. She is searching for the solution but maybe needs to change the path to /data/local/tmp.
Step 2 Is to execute ping _data and cgi-bin, traceroute.pl <http://traceroute.pl/>
Step 3: To execute pinger2.pl <http://pinger2.pl/> that will start gathering data
- She is using perl-android-apk Interpreter to run perl on android. It includes execution of 3 perl scripts:

Perl-android-interpreter application was depreciated so install perl package using GNURoot Debian Application
"Make install" issue is resolved too it create directorys and files required by pinger2 in usr/local/share/pinger
But now when i execute pinger2.pl <http://pinger2.pl/> (that will ping host and start getting data) using IP address its generating two errors image is attached. IP address is also updated in pinger.xml
First error is," cannot exec DnsV4Cmd.pl, file not found", but DnsV4Cmd.pl is in PingER directory with execute permission.
- Second error, "SrcIP could not be determined for DNS 203.124.57.137. Without the results produced by PINGER2 is not usable.".
- Les suspects the second error is result of the 1st error. maybe using the perl -d debugger would assist.

As of 7/30/2016 the following hosts are down and not responsive for >= 1 month. Anas Abrar reports the nodes were contacted many times for identifying their issues. i.e turn on their pinGER Computers but never responded well. Some have already been Disabled, (striketroughs strikethroughs as proposed at the 6/22/2016 meeting and hearing nothing from Pakistan following the meeting), I will disable the others if I hear nothing.

^ Not seen in July 2016
Les proposes 7/30/2016):
- Give up (i.e. remove from Monitoring node table by setting Projecttype to D (for Disabled)) on non-responsive hosts not working for a month.
- 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-date. has provided a cronjob to automatically update the PingER hourly data on. He has also provided for a client to get new data via the web. Needs documenting.
Also has a 4 node cluster with Cloudera manager for Hadoop, Next step are to get impala working for queries.

"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.
