On startup, nmxptool reads the configuration file named on the command line. Commands in this file set all the parameters used for configuring the Earthworm Nanometrics client module nmxptool (Nanometrics). In the control file, lines may begin with a valid nmxptool command (listed below) or with one of 2 special characters:
Command names must be typed in the control file exactly as shown in this document (commands are case sensative). Blank lines are also permitted in the control file.# marks the line as a comment (example: # This is a comment).
@ allows control files to be nested; one control file can be
accessed from another with the command "@" followed by
a string representing the path name of the next control file
Below are the commands recognized by nmxptool, grouped by the function
they influence. Most of the commands are required; they may be
specified in any order in the control file.

Channel streamkey ReadConfig nmxptool parameters
Specifies one stream of data to be requested from the NmxpHost. The streamkey is not in SCNL format. It is composed of a network, station and channel code separated by period. network is optional and it is used only for output. Station code can be "*" that stands for all stations. Within channel code can appear character "?" that stands for any characters. Location value is always set to "--". DO NOT USE WITH ChannelFile!Default: none Example: Channel ES.BOB.HH? Channel MN.TIR.HH? Channel SALO.HH? Channel *.HHZ N.B. Network code will be assigned from the first pattern that includes station and channel. Unless HH channels of BOB and TIR, all other stations will have default network code from DefaultNetworkCode.
ChannelFile channel_state_file ReadConfig nmxptool parameters
Specifies one or more streams of data to be requested from the NmxpHost. The streamkey is the same for the Channel. Allow data continuity when short disconnections to NaqsServer occur requesting data buffered by NaqsServer (read Advanced Description for setting DataBufferLength) and, optionally, retrieving data from DataServer within seconds defined by MaxDataToRetrieve. This file is created by the user, nmxptool will update date and time of last sample received for each channel into the file "channel_state_file.nmxpstate". DO NOT USE WITH Channel!Default: none Example: ChannelFile /home/ew/list_channels_naqs1.txt Example of file created by the user: ES.BOB.HH? MN.TIR.HH? SALO.HH? *.HH? N.B. Network code will be assigned from the first pattern that includes station and channel. Unless HH channels of BOB and TIR, all other stations will have default network code from DefaultNetworkCode.

DefaultNetworkCode network_code ReadConfig nmxptool parameters
Specifies default network code for channels where is omitted.
Example: DefaultNetworkCode IV
ForceTraceBuf1 switch ReadConfig Earthworm setup
Sets the on-off switch to force the creation of TRACEBUF messages on systems that support TRACEBUF2 messages. By default, the module will create TRACEBUF2 messages on systems that support them otherwise it will create the older TRACEBUF messages. This switch has no effect on systems that do no support TRACEBUF2 messages. This switch could be useful in environments where a transition is occuring between TRACEBUF and TRACEBUF2 messages, otherwise most people will never use this.
Default: 0 (disabled)
Example: ForceTraceBuf1 1
HeartBeatInterval interval ReadConfig Earthworm setup
Defines the interval in seconds at which the module will issue TYPE_HEARTBEAT messages.
Example: HeartBeatInterval 30
LogFile switch ReadConfig Earthworm setup
Sets the on-off switch for writing a log file to disk. If switch is 0, no log file will be written. If switch is 1, nmxptool will write a daily log file(s) called nmxptool.log_yymmdd where xx is nmxptool's module id (set with MyModuleId command) and yymmdd is the current UTC date (ex: 960123) on the system clock. The file(s) will be written in the EW_LOG directory (environment variable). If switch is 2 the log file is written but output to stdout and stderr is suppressed.
Example: LogFile 1
MaxDataToRetrieve seconds ReadConfig nmxptool parameters
Max amount of data of the past to retrieve from the DataServer when program restarts. 0 to disable connection to DataServer. If this parameter is zero and ChannelFile is used, only data buffered by NaqsServer will be retrieved. Rather than using MaxDataToRetrieve, it is preferable, inside the section Datastream of the file Naqs.ini, setting DataBufferLength to a high value (read Advanced Description). MaxDataToRetrieve allows to retrieve much more data of the past when the program restarts but it considerably slows down the execution. It is extremely harmful when you have many channels, in this case you might consider to subdivide the channels into different nmxptool instances. Range is [0..86400].
Example: MaxDataToRetrieve 3600
MaxTolerableLatency seconds ReadConfig nmxptool parameters
Specifies the max tolerable latency for raw stream connection. For enabling NaqsServer to send out retransmission requests for missed packets set RetxRequest (read Advanced Description). If RetxRequest is not enabled then MaxTolerableLatency is ineffective. Range is [60..600]. NOT use with parameter ShortTermCompletion.
Example: MaxTolerableLatency 200
MyModuleId mod_id ReadConfig Earthworm setup
Sets the module id for labeling all outgoing trigger, heartbeat, and error messages. mod_id is a character string (valid strings are listed in earthworm.d) that relates to a unique single-byte number.
Example: MyModuleId MOD_NMXPTOOL
mschan mSECs/nC ReadConfig nmxptool parameters
mSECs are milliseconds to wait before the next request, nC is the number of channels to request at a time. Delaying and requesting few channels at a time make data buffering on NaqsServer side more efficient. Determined empiric values are default 280/9. 0/0 for disabling. Condition: TotalNumberOfChannels * (mSECs/nC) < 15 sec.
Example: mschan 350/12
NmxpHost address ReadConfig nmxptool parameters
Specify the address of the Nanometrics server. This can be either on IP address (four period-separated numbers) or the domain name of the server.
Example: NmxpHost naqs1a.int.ingv.it
NmxpPortDAP port ReadConfig nmxptool parameters
Specifies the IP port number for the DataServer (NmxpHost). This is commonly 28002.
Example: NmxpPortDAP 28002
NmxpPortPDS port ReadConfig nmxptool parameters
Specifies the IP port number for the NaqsServer (NmxpHost). This is commonly 28000.
Example: NmxpPortPDS 28000
PassDAP password ReadConfig nmxptool parameters
Specifies the password for the DataServer (NmxpHost). Leave commented if password in DataServer.ini is set to "none".
Example: PassDAP mypass
RingName ring ReadConfig Earthworm setup
Indicates which shared memory region to use for waveform output. ring is a character string (valid strings are listed in earthworm.d) that relates (in earthworm.d) to a unique number for the key to the shared memory region.
Example: RingName WAVE_RING
ShortTermCompletion seconds ReadConfig nmxptool parameters
Specifies the Short-Term-Completion for Buffered stream connection. Ranges:
NOT use with parameter MaxTolerableLatency.
0 decompressed packets are received in chronological order without waiting for missing packets. [1..300] decompressed packets are received in chronological order but waiting for missing packets at most SECs seconds.
Example: ShortTermCompletion 120
TimeoutRecv seconds ReadConfig nmxptool parameters
Specifies time-out for flushing buffered packets for each channel. Useful for Data On Demand (i.e. channel HN? or HL?). It sets mschan to 0/0. Range is [10..300].
Default: 0 (No Time-out)
Example: TimeoutRecv 15
UserDAP username ReadConfig nmxptool parameters
Specifies the username for the DataServer (NmxpHost). Leave commented if username in DataServer.ini is set to "none".
Example: UserDAP mtheo
Verbosity level ReadConfig Earthworm setup
Specifies the level of logging verbosity. Verbosity is a bitmap:
1 Channel State, 2 Channel, 4 Raw Stream, 8 CRC32, 16 Connection flow, 32 Packet Management, 64 Extra, 128 Date, 256 Gap, 512 DOD, 1023 All messages.
Example: Verbosity 80 # 16 Connection flow + 64 Extra
[ Datastream ] Port = 28000 // TCP port for control/data connections to Naqs Password = none // access password (not used in version 1.3) MaxConnections = 10 // maximum number of simultaneous connections SocketType = Direct // connection type (Direct or Callback) DataBufferLength = 100 // Buffer length for data channels (# packets)
[ NetworkInterface ] Port = 32000 // UDP port for incoming NMX data (usually 32000) SendDelay = 250 // milliseconds to delay after each send RetxRequest = Enabled MulticastGroup = 126.96.36.199
