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.
Earthworm system setup:
Nanometrics server and connection parameters:
ChannelFile required Xor Channel
Channel required Xor ChannelFile
In the following section, all configuration file commands are listed in alphabetical order. Listed along with the command (bold-type) are its arguments (in red), the name of the subroutine that processes the command, and the function within the module that the command influences. A detailed description of the command and is also given. Default values and example commands are listed after each command description.

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 between program restarts, within time defined by MaxDataToRetrieve and data buffered by the DataServer and NaqsServer. 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. 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. Range is [0..86400].
Example: MaxDataToRetrieve 3600
MaxTolerableLatency seconds ReadConfig nmxptool parameters
Specifies the max tolerable latency for raw stream connection. Range is [60..600].
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
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
TimeoutRecv seconds ReadConfig nmxptool parameters
Specifies time-out for flushing buffered packets for each channel. Useful for Data On Demand (i.e. channel HL). 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
# # Configuration File for nmxptool # MyModuleId MOD_NMXPTOOL RingName WAVE_RING # Transport ring to write data to. HeartBeatInterval 10 # Heartbeat interval, in seconds. LogFile 1 # 1 -> Keep log, 0 -> no log file # 2 -> write to module log but not stderr/stdout #ForceTraceBuf1 0 # On systems that support TRACEBUF2 # messages this flag will force the module # to create TRACEBUF messages instead. # Most people will never need this. Verbosity 16 # Set level of 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. # It is equivalent to the option -v. NmxpHost naqs1a.int.ingv.it # NaqsServer/DataServer hostname or IP address. # It is equivalent to the option -H. NmxpPortPDS 28000 # Port number of NaqsServer (Default 28000) # It is equivalent to the option -P. NmxpPortDAP 28002 # Port number of DataServer(Default 28002) # It is equivalent to the option -D. #UserDAP mtheo # DataServer user name. Commented if 'none'. # It is equivalent to the option -u. #PassDAP mypass # DataServer password. Commented if 'none'. # It is equivalent to the option -p. MaxTolerableLatency 120 # Max tolerable latency for each channel.

No time-out) [10..300]. # Useful for retrieving Data On Demand with minimum delay. # 'tsec' in nmxptool.desc should be greater than 'TimeoutRecv'. # It is equivalent to the option -T. DefaultNetworkCode IV # Default network code where in 'ChannelFile' or 'Channel' is not declared. # It is equivalent to the option -N. # N.B. nmxptool channel definition IS NOT equal to SCNL # It is NSC, that is NET.STA.CHAN # NET is optional and used only for output. # STA can be '*', stands for all stations. # CHAN can contain '?', stands for any character. # Localtion value is always equal to "--". # Related to the parameters 'ChannelFile' and 'Channel'. # Network code will be assigned from the first # pattern that includes station and channel. # Example: N1.AAA.HH?,N2.*.HH?,MMM.BH? # Second pattern includes the first. Unless AAA, all # stations with HH channels will have network to N2. # Station MMM will have default network defined by 'DefaultNetworkCode'. #MaxDataToRetrieve 3600 # Max amount of data of the past to retrieve from the # DataServer when program restarts (default 0) [0..86400]. # 0 to disable connection to DataServer. # It is equivalent to the option -A. Related to 'ChannelFile'. # If 'MaxDataToRetrieve' 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. # '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.
