  1. PingER web services: ?
    1. PingER & AMP Integration (AMP/NLANR has run out of funding, AMP will shut down 8/31/06. Given the demise of AMP this may need to be changed to integration with PerfSONAR): Asif
      1. Document work with AMP integration (hope to complete 11/18/06): Abdullah
      2. Extend to provide perfSONAR data reading front end: Abdullah, Asif

        6. AMP and Pinger data comparison: Abdullah
    2. Smokeping & PingER Integration: Asma (Umar is trying to reach Asma 1/2/07), Asma, Shahryar
      1. Look at how to input PingER data to Smokeping display module (sounds like we have to convert from PingER to RRD format, can this be done in realtime or do we need an RRD database too): Asma
      2. Look at how to to take recent smokeping data and convert to PingER format (in progress 7/19/06, needs to get all 12 metrics)
      3. Install on (RRD problem fixed 11/30/06) - Asma
      4. Install at SLAC: Shahryar

      5. Change from 90 to 120 days - Asma
      6. Look at adding visualization of uptime: Asma
      7. Look at how to dynamically change the config file for Smokeping to accomodate the step interval (maybe time consuming, may affect all users and be cumbersome): Asma
      8. Look at using Smokeping to determine the quality of home links in Pakistan: Asma
      9. Will use as a top level access to PIngER and also as links from Pingtable to display last 45-90 days using smokeping: Asma, Yee
    3. Provide real-time display of PingER data:
      1. Export data to MonALISA from SLAC monitoring site:
      2. Figure how to deal with non regular (non exact 30 min data)
      3. Do for SLAC

      1. NTC hosts, they agreed to install PingER2 at their 3 backbone sites (NTC management has changed, NIIT shifted from NTC to PERN, does not look promising): Arshad, Azher
      2. Pakistan hosts
        1. NTC is down since Oct 17th (NTC management has changed, Arshad will contact upper management 12/4/06) [After talking to NTC does not sound likely this will be restored, 1/11/07]: Azher, Jerrod
        2. COMSATS do not ping (Azher reports that COMSATS is very unreliable operation of PingER host): Azher
        3. PERN does not ping and reverse traceroute server is down (need to decide whether to give up on this host and remove it from our list of hosts to use for PingER and TULIP): Azher
        4. PERN would like to provide own archive analysis host (Les has sent URL describing tools needed on archive/analysis host, it maybe that iepm-bw would be more useful to them):

Triangulate position of an unknown host (see,Faran Faran expects to be able to devote more effort to this following 25th Jan 2007): Faran, Les

  1. Deployment: Faran
    1. Provide a program API: Faran, Shahryar (dropped)
    2. Refine the list in Sites.txt by writing a script that will run TULIP HTTP requests to ping to see which landmarks are not responding (agreed 11/16/06, do we really need it, if so can we reduce its priority): Faran
    3. Provide opotion so that Sites.txt can be modified from TULIP. (agreed 11/16/06, currently the master is kept at SLAC and one has to logon to SLAC to modify it): Faran

    3. Provide tool to geolocate all PingER sites, analyze results to see what landmarks never respond; Faran
    4. Problem Landmarks:
      1. denies accesss (email to Azher & Faran 7/25/06, Azher responded that he is checking 7/27/06, email sent again 8/21/06, Azher knows about will send person to repair 8/22/06) see also above for the PingER node at this site: Faran/Azher
      2. Enable landmarks that only work for IP addresses: Faran
