On startup, nq2audio reads the configuration file named on the command line. As always, the configuraton file contains comments:
Command names must be typed in the control file exactly as shown in this document (upper/lower case matters!). nq2audio supports one diagnostic command line option, -v is for verbose mode so that you can see packets coming in.# marks the line as a comment (example: # This is a comment).
Below are the configure commands recognized by nq2audio, grouped by the function
they influence. Most of the commands are required.
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.
Here is a copy of the nq2audio.desc file as implemented. Note that all causes of
death for nq2audio feed through the function q2ew_die() which logs all causes of
death using logit() and sends a message to the statmgr utility.
1. EXAMPLE CONFIGURATION FILE
#
# nq2audio configuration file
#
# This code receives MiniSEED records as files, converts them into
# audio files in .au format.
#
#
ModuleId MOD_NQ2AUDIO # module id for this import,
InRingName HYPO_RING # shared memory ring for input
HeartbeatInt 10 # Heartbeat interval in seconds
# this should match the nq2audio.desc heartbeat!
LogFile 1 # If 0, don't write logfile;; if 1, do
# if 2, log to module log but not stderr/stdout
# Directory where we should look for the NetQuakes miniSEED files
NQFilesInDir /home/luetgert/getfiles/netquakes
# Directory where the successfully processed files are put
NQFilesOutDir /home/luetgert/getfiles/netquakes/save
# Directory where the problem files are put
NQFilesErrorDir /home/luetgert/getfiles/netquakes/trouble
# Directory where the audio files are put
NQFilesAudioDir /home/luetgert/getfiles/netquakes/audio
# Debug switch: the token "Debug" (without the quotes) can be stated.
# If it is, lots of weird debug messages will be produced
# Debug
2. FUNCTIONAL COMMAND LISTING
Earthworm system setup:
MyModuleId required
RingName required
HeartbeatInt required
Output Control:
LogFile required
3. ALPHABETIC COMMAND LISTING & DESCRIPTION
command arg1 processed by function
HeartbeatInt beat HeartBeat Earthworm setup
Beat the nq2audio heart every beat seconds.
Default: 0 - do not use logit() for LOG channels
LogFile switch GetConfig 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, nq2audio
will write a daily log file(s) called q2ewxx.log_yymmdd
where xx is nq2audio'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).
Default: none
MyModuleId mod_id GetConfig Earthworm setup
Sets the module id for labeling all outgoing messages. mod_id is
a character string (valid strings are listed in earthworm.d) that
relates (in earthworm.d) to a unique single-byte number.
Default: none
Calnet: MyModuleId MOD_NQ2AUDIO
RingName ring GetConfig Earthworm setup
This is the ring into which the messages are sent.
Default: none, required option
ATWC: RingName HYPO_RING
