Ibrahim Abaker is planning to work on a topic initially entitled " leveraging pingER big data with a modified pingtable for event-correlation and clustering", The purpose of this project is to make Pinger more efficient and more scalable to retrieve and analysis pingER raw data. Consequently it may improve pinger data store. He is planning to use key-value store model with high expandability and shorter query response time. The benefit of such project will help in the design of real time analysis and distributed pinger data across multiple servers for analysis. Les has sent him a pointer to documentation on the data flow at SLAC and also listings of pingtable.pl and associated script. He is currently writing a proposal, which will contain a problem statement, objectives, scope and the approach to tackle the problem. He asked: how much PingER data is captured and stored so far (~ 1TByte)? Is there a published paper (see http://www-iepm.slac.stanford.edu/paperwork/ieee/ieee.pdf)? Bebo & Les will set up a Skype meeting with Renan to get an update and see about setting up direct contact between Renan and Ibrahim. Ibrahim provided a copy of his proposal (see https://confluence.slac.stanford.edu/download/attachments/17162/leveraging%20pingER%20big%20data%20with%20a%20modified%20pingtable%20for%20event-correlation%20and%20clustering.docx).

No progress 2/19/2014. Johari was not on the call.

- Rebuild from scratch. in the initial case Umar took 2-3 weeks. he wrote documentation, so this will be a test of the documentation. This could be valuable should Malaysia or another site decide to set up an archive. kashif and Joun are ready to start on this.
- Dump and restore the database. This is much easier. However it requires the database password. Les will contact Umar to see if he can provide the password. Umar canot logon to maggie1 since it is blocked by the firewall.
The BeaconList BeaconLists at NUST and SLAC are out of sync. Raja will compare the two pinger.xml files. It turns out NUST was not using the HostList for the non Beacons and so had ane xpanded an expanded BeaconList which was updated from SEECS. Raja has explained this to NUST and believe it will be easy to synchronize.
Hassaan reports that they have established contact with people in Bahawalpur. The contact person forwarded the request to higher authorities for approval of PingER deployment. Same status 3/5/2014
The installation of PingER at Sahiwal is complete. It just needs the Beacon List.

Anjum pointed out that there are working PingER monitors that SLAC appears unable to gather data from. An example is the Comsats host. Les takes this to mean pinger.comsats.edu.pk and will investigate.
