scevtstreams

Extracts stream information and time windows from an event.

Description

scevtstreams reads all picks of an event and determines the time window between the first pick and the last pick. In addition a time margin is added to this time window. It writes the streams that are picked including the determined time window for the event to stdout. This tool gives appropriate input information for scart to archive event based data.

Examples

Create a playback of an event with a time window of 5 minutes data and sort the records by end time:

scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp3 -L 0 -m 300 |
scart -dsvE --list - ~/seiscomp3/acquisition/archive > gfz2012abcd-sorted.mseed

Download waveforms from Arclink and import into local archive:

scevtstreams -E gfz2012abcd -d mysql://sysop:sysop@localhost/seiscomp3 -L 0 -m 300 -R |
scart --list - ./my-archive

Command-line

Generic

-h, --help

show help message.

-V, --version

show version information

--config-file arg

Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it, eg scautopick -> scautopick2.

--plugins arg

Load given plugins.

-D, --daemon

Run as daemon. This means the application will fork itself and doesn't need to be started with &.

--auto-shutdown arg

Enable/disable self-shutdown because a master module shutdown. This only works when messaging is enabled and the master module sends a shutdown message (enabled with --start-stop-msg for the master module).

--shutdown-master-module arg

Sets the name of the master-module used for auto-shutdown. This is the application name of the module actually started. If symlinks are used then it is the name of the symlinked application.

--shutdown-master-username arg

Sets the name of the master-username of the messaging used for auto-shutdown. If "shutdown-master-module" is given as well this parameter is ignored.

Verbosity

--verbosity arg

Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug

-v, --v

Increase verbosity level (may be repeated, eg. -vv)

-q, --quiet

Quiet mode: no logging output

--component arg

Limits the logging to a certain component. This option can be given more than once.

-s, --syslog

Use syslog logging back end. The output usually goes to /var/lib/messages.

-l, --lockfile arg

Path to lock file.

--console arg

Send log output to stdout.

--debug

Debug mode: --verbosity=4 --console=1

--log-file arg

Use alternative log file.

Database

--db-driver-list

List all supported database drivers.

-d, --database arg

The database connection string, format: service://user:pwd@host/database. "service" is the name of the database driver which can be queried with "--db-driver-list".

--config-module arg

The configmodule to use.

--inventory-db arg

Load the inventory from the given database or file, format: [service://]location

--db-disable

Do not use the database at all

Dump

-E, --event arg

Specifies the event id.

-m, --margin arg

Time margin in seconds added to the final stream time window, default 300.

-S, --streams arg

Comma separated list of streams per station to add, e.g. BH,SH,HH.

-C, --all-components flag

Specifies whether to use all components (0) or just the picked one (1), default 1.

-L, --all-locations flag
