  1. MSNet MSNet is an easy to install,use, maintain and modify open source written in Perl. It polls remote stations, declares events based on time, makes s-files, retrieves and stores waveforms into Seisan databases. Written by Angel “all automatic” Rodriguez

  2. Why Perl language? “To make easy jobs easy and hard ones possible” • It's strengths are: • free and available on all platforms • Powerful file and string manipulation • Powerful use of regular expressions in pattern matching

  3. Why did I write MSNet? • Because I am lazy. • In the begging it was all manual. • Then I wrote some batch files that got all events, manual processing. It consumed lot of bandwidth. • Jens suggested and outlined the program • Now it is all automatic, EEV ready with almost no bandwidth use.

  4. Does it work?You bet! • Has been running on my system for 3 month. • In February it made about 300 s-files • Has not yet crashed or stopped working • Consumes very little processor resources • Consumes very little bandwidth • Very easy to modify stations • Very easy to modify the program itself

  5. MSNet does it's job in five main steps • It first build a list of stations real or virtual. • It connects to each station on the list and gets the waveform file names, not the files. • It declares events and makes S-files based on the time extracted from the file name. • It then reconnects only the stations and gets only the waveforms that were used in the making of the S-files • It then deletes waveform files at reconnected stations based on user defined variables.

  6. Each remote station needs a setup file • If you have a network with 20 station then you would need 20 “.station” files. • To not visit a station you just remove the station file from the folder. • You can make virtual stations to get just some files from a database.

  7. Setting up MSNetMSNet needs an MSNet.ini file • STATION_HOME = c:\seismo\MSNet\ • STATION_EXTENSION = .station • LOG_PATH = c:\seismo\MSNet\ • REA_BASE = C:\seismo\REA\demo_\ • EVENT_STORE = C:\seismo\WAV\ • TIMEOUT = 0 • VERBOSE = yes • LOG = MSnet.log • PROCESSING_DAYS = 1 • ARRAY_PROP_TIME = 30 • DECLARE_EVENT = 3

  8. BRU2.station • IP = 64.116.183.137 # this is a comment • LOGIN = demo # user name • PASSWORD = demo1 • REMOTE_WAVE_FORM_DIR = /Seislog/ • STATION_TYPE = seisan • DELETE_FILES = 99 • MTTNE = 170 • # this is also a comment

  9. MSNet does it's job in five main steps • It first build a list of stations real or virtual. • It connects to each station on the list and gets the waveform file names, not the files. • It declares events and makes S-files based on the time extracted from the file name. • It then reconnects only the stations and gets only the waveforms that were used in the making of the S-files • It then deletes waveform files at reconnected stations based on user defined variables.

  10. Seaian::Tools • Converts Seisan to Nordic and vis-a-versa. • Converts Seisan or Nordic into Unix epoch time reference. • Converts Seisan and Nordic into DateTime::Precise format. • Given a list of waveform files, returns an s-file. • Given a waveform file and the name of an s-file. add to the s-file. • Sorts an array of waveform files by Unix epoch time.

  11. Future Enhancements and Know issues • Automatic location and notification • Get and convert different file formats on the fly. • Implement more SeisNet features • Question and Answers?
