Minutes for SLAC SEECS Meeting March 6th, 2012
General
We may not be able to get the MATLAB Toolkit for Tulip. Dr. Anjum proposed that we can use Mathemetica instead of MATLAB. He also proposed that he will try to find out some MS students who might take this conversion as his MS thesis. Students have to finalize their thesis by 6th April. By the second week of April, we will get to know if we have any student doing this.
Bilal is on one week leave, he will not be joining us for this meeting.and Dr. Anjum were unavailable this week, pre-informed. Ghulam did not show up.
IPV6 - Anjum and Ghulam (this has been de-prioritized until new database PingER is working)
...
Next we need to make pingtable.pl and getdata.pl IPV6 capable, again this could use valid_ip.pl. Since Ghulam and Sadia are working on these it would be good for them to add this.
We were unable to log in to IPV6 machine at SEECS. Dr. Anjum told that: password for pinger machine has been changed because all these machines are virtual machines so we cant share them with everybody. Joun will share the passwords of pinger machine with Les. Kashif sattar sent an email to Les for sharing username and ?passwords for Maggie1 and Maggie2 on 29th Feb, but we haven't yet acted upon it.
pinger2.pl
Joun has installed the latest version pinger2.pl that is not supposed to lose <BeaconsList> at 3 sites (cae.seecs.edu.pk, maggie2.seecs.edu.pk, aup.seecs.edu.pk). We will have a better idea of whether it works at the end of the month when the sites get updated.
What are the updates on these 3 hosts, Joun? Amber send joun an email and ask.
We have defined how to force updates of the <BeaconList> fro SLAC. However, it is not implemented.
...
- Collection status webpage generates an email if a node does not work for more than 10 days. put it on web saying for first n days we do not get report.
- Connectivity.pl is fixed to display the latest data (of hours of day that have passed) results on the web.
- Harway Newman sent new measurement results of HDI for 2011. These new results have been added to both Motion charts and Pinger Data explorer. Both of them are working fine.
...
Imdadullah will be writing an executive summary of the report which needs to be submitted before the end of this month. Now the report goes to other universities as well as to the head of HEC. We now need to be very careful in writing the report.
The report is was supposed to be submitted todaylast monday. A few changes were made in the conclusions . An executive summary will also be sharedand an executive summary. We wait till next meeting for updates.
Pakistani Host
Joun and Ghulam have arranged to archive the statu sof Pakistani hosts in http://pinger.seecs.edu.pk/daily-report. It appears future copies be saved there*
...
SEECS have not heard about the IP change from HEC. Dr Anjum will remind HEC about the IP changes to be made by the end of this weeklast week. We wait till nest week for updates.
PingER Archive Site - Ghulam
...
Bilal is writing a report with stress testing results of all of the regions. He will be sharing it when it completes.
PerfSONAR (Pakistan)

Possible projects
- There can be a paper kind of talking on Pinger if we could just find the right conference. MCN, ICC and Globecomm do provide network monitoring topics. We can talk of GEO-Location experiences. For example within Pakistan it works fine, however as we go within regions or continents this gets worse. We can publish some stats on that for example. We are yet not ready for Tulip paper.
Wiki Markup See \[https://confluence.slac.stanford.edu/display/IEPM/Future+Projects\].
- Extend the NODEDETAILS data base to allow entry support for whether the host is currenty pingable.
Wiki Markup Extend Checkdata to provide emails automatically, see \[https://confluence.slac.stanford.edu/display/IEPM/Extend+checkdata+to+make+it+more+useful\]. Many of the ideas in the script node-contacts.pl are a step in this direction. *Amber is working on this*
- Improve the PingER2 installation procedures to make it more robust. This might be something for the person(s) in Pakistan who are responsible for installing PingER2 at the Pakistani monitoring sites. They probably have found where the failures occurs. Also look at the FAQ, and ping_data.pl which has been improved to assist in debugging, could it be further improved (e.g. provide access to the httpd.conf file so one can see if it properly configured)? There are 2 students working on the PingER archive. Is this something they could work on?
- [Fix PingER archiving/analysis package to be IPv6 conformant|IEPM:Make PingER IPV6 compliant]. Will build a proposal for an IPv6 testbed. They will try various transition techniques. A proposal has been prepared and that has been submitted to PTA. Adnan is a co PI. It is being evaluated today. A small testbed has been established in SEECS and the plan to shift some of the network to IPv6. Bilal is part of 3 students involved with PingER and they will be involved with IPv6. They are porting the PingER archive site site to using a database. They have redeveloped the archive site using Umar's documentation. They have set up a small test archive site. They have gathering, archiving, analysis. They will design a new database. They will also try a port of PingER to IPv6.
- Look at RRD event detection based on thresholds and how to extend, maybe adding plateau algorithm. Umar's algorithm did not work in a predictable manner.
- Provide near realtime plots of current pinger data using getdata_all.pl/wget. It will work as a CGI script with a form to select the host, the ping size, and the time frame to plot. It will use wget or getdata_all.pl to get the relevant data and possibly RRD/smokeping to display the data. Amber is looking at.
