MedNet - nmxptool: software for Nanometrics seismic data acquisition

 Rischio Sismico, Rischio Vulcanico, Rischio di Non Sapere.

Le informazioni contenute in queste pagine sono state sinora garantite dal lavoro del personale, precari e non, dell'Istituto Nazionale di Geofisica e Vulcanologia.

Il personale dell'INGV ha decretato lo stato di agitazione contro l'emendamento 37bis alla proposta di legge 1441 quater, che provocherebbe il licenziamento del personale precario portando ad uno stato di crisi le attività istituzionale svolte dall'Ente. Di conseguenza si procederà alla sospensione dell'informazione telematica e telefonica non istituzionale, relativa ai terremoti che avvengono sul territorio nazionale.

 Seismic Risk, Volcanic Risk, Information Risk.

The information on these pages have been so far provided by the staff of INGV, which includes a large number of temporary workers.

The government now proposes to dismiss all the temporary workers (amendment 37 bis to the 1441 quater bill) thus bringing about a serious crisis in the institutional activity of INGV. Against this decision the staff as a whole will stop the release of all non-institutional information relating to national earthquakes.

nmxptool

NEW!!! Current version of nmxptool is 1.2.3 (2009/01/15) NEW!!!

Open-Source and Cross-Platform software for Nanometrics seismic data acquisition

The Nanometrics servers NaqsServer and DataServer can provide on-line access to seismic data and state-of-health information accepting TCP/IP connections and forwarding the requested data to each client program. NaqsServer collates and stores in near-real-time incoming data in ringbuffers whereas DataServer provides data of the past stored in NaqsServer ringbuffers. In order to implement the Nanometrics subscription protocols, the author developed a software consisting of a library called libnmxp and a tool called nmxptool. The library exposes a set of documented APIs which allow to communicate with the Nanometrics servers. The tool, based on libnmxp, allows to retrieve or monitor real-time data and data of the past.

nmxptool can be used in three different ways: (see also the diagram)

The main contribute, as regards other similar software, is the capability to manage Raw Stream connections by buffering and sorting all received packets, included the retransmitted ones, guaranteeing a good compromise between data continuity and low latency. Besides, nmxptool allows to retrieve Data-On-Demand with minimum delay after request. Software is open-source and released under GNU Library General Public License. It has been written in C language using the GNU Build Tools (automake, autoconf and configure script) and taking in account the cross-platform compilation aspects, in fact, it can run on almost all the Unix-like operating systems, Mac OS X, Windows and either 32-bit or 64-bit architectures.
