rs2caps¶

Recordstream data acquisition plugin

Description¶

rs2caps uses the SeisComP RecordStream [4] to feed data into caps of to stdout.

Examples¶

Inject data into the CAPS server:
```
seiscomp start caps
rs2caps -I data.mseed --passthrough
```
Read the examples section to learn how to use rs2caps to input data into the CAPS server.

Read data from the file data.mseed resample to 10 Hz sample rate by the RecordStream and write the resulting data to stdout:

rs2caps -I resample://file?rate=10/data.mseed --passthrough --dump-packets --mseed > test.mseed

You may join the command with capstool [8] and scmssort [14]:

echo "2024,01,01,00,00,00 2024,01,01,00,10,00 * * * *" | capstool -H localhost |\
rs2caps -I resample://file?rate=10/- --passthrough --dump-packets --mseed |\
scmssort -E > test.mseed

Note

A similar action with additional data processing may be executed using sproc2caps.

Module Configuration¶

etc/defaults/global.cfg
etc/defaults/rs2caps.cfg
etc/global.cfg
etc/rs2caps.cfg
~/.seiscomp/global.cfg
~/.seiscomp/rs2caps.cfg

rs2caps inherits global options.

Note

Modules/plugins may require a license file. The default path to license files is @DATADIR@/licenses/ which can be overridden by global configuration of the parameter gempa.licensePath. Example:

gempa.licensePath = @CONFIGDIR@/licenses

output.address¶

Default: localhost:18003

Type: string

Data output URL [[caps|capss]://][user:pass@]host[:port]. This parameter superseds the host and port parameter of previous versions and takes precedence.

output.host¶

Default: localhost

Type: string

Data output host. Deprecated: Use output.address instead.

output.port¶

Default: 18003

Type: int

Data output port. Deprecated: Use output.address instead.

output.timeout¶

Default: 60

Unit: s

Type: int

Timeout when sending a packet. If the timeout expires the connection will be closed and re-established.

output.maxFutureEndTime¶

Default: 120

Unit: s

Type: int

Maximum allowed relative end time for packets. If the packet end time is greater than the current time plus this value, the packet will be discarded. By default this value is set to 120 seconds.

output.bufferSize¶

Default: 1048576

Unit: bytes

Type: uint

Size (bytes) of the packet buffer.

output.backFillingBufferSize¶

Default: 0

Unit: s

Type: int

Length of backfilling buffer. Whenever a gap is detected, records will be held in a buffer and not sent out. Records are flushed from front to back if the buffer size is exceeded.

output.mseed.enable¶

Default: false

Type: boolean

Enable on-the-fly miniSEED encoding. If the encoder does not support the input type of a packet it will be forwarded. Re-encoding of miniSEED packets is not supported.

output.mseed.encoding¶

Default: Steim2

Type: string

miniSEED encoding to use. (Uncompressed, Steim1 or Steim2)

streams.begin¶

Type: string

Start time of data time window, default ‘GMT’

streams.end¶

Type: string

End time of data time window

streams.days¶

Default: -1

Unit: day

Type: int

Use to set the start time of data time window n days before the current time.

streams.daysBefore¶

Default: -1

Unit: day

Type: int

Use to set the end time of data time window n days before the current time.

streams.passthrough¶

Default: false

Type: boolean

Do not subscribe to any stream and accept everything a record source is passing. This is useful in combination with files.

journal.file¶

Default: @ROOTDIR@/var/run/rs2caps/journal

Type: string

File to store stream states

journal.flush¶

Default: 10

Unit: s

Type: uint

Flush stream states to disk every n seconds

journal.waitForAck¶

Default: 60

Unit: s

Type: uint

Wait when a sync has been forced, up to n seconds

journal.waitForLastAck¶

Default: 5

Unit: s

Type: uint

Wait on shutdown to receive acknownledgement messages, up to n seconds

journal.syncWithBindings¶

Default: false

Type: boolean

Whether to synchronize the journal file with bindings. If enabled then each time update-config is called, the bound stations will be synchronized with the current journal file. Unbound stations will be removed from the journal. Synchronizing with bindings will disable reading the inventory.

statusLog.enable¶

Default: false

Type: boolean

Log information status information e.g. max bytes buffered

statusLog.flush¶

Default: 10

Type: uint

Flush status every n seconds to disk

Bindings Parameters¶

selectors¶

Type: list:string

List of stream selectors in format LOC.CHA. If left empty all available streams will be requested.

Command-Line Options¶

Generic¶

-h, --help¶: Show help message.

-V, --version¶: Show version information.

-D, --daemon¶: Run as daemon. This means the application will fork itself and doesn’t need to be started with &.

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.

-s, --syslog¶: Use syslog logging backend. The output usually goes to /var/lib/messages.

Records¶

--record-driver-list¶: List all supported record stream drivers.

-I, --record-url arg¶: The recordstream source URL, format: [service://]location[#type]. "service" is the name of the recordstream driver which can be queried with "--record-driver-list". If "service" is not given, "file://" is used.

--record-file arg¶: Specify a file as record source.

--record-type arg¶: Specify a type for the records being read.

Output¶

-O, --output arg¶

Overrides configuration parameter output.address.

This is the CAPS server which shall receive the data.

--agent arg¶: Sets the agent string. Allows the server to identify the application that sends data.

-b, --buffer-size arg¶: Size (bytes) of the journal buffer. If the value ist exceeded, a synchronization of the journal is forced.

--backfilling arg¶

Default: 0

--encoding arg¶: miniSEED encoding to use: Uncompressed, Steim1 or Steim2.

--rec-len arg¶: miniSEED record length expressed as a power of 2. A 512 byte record would be 9.

--dump-packets¶: Dump packets to stdout.

--test¶: Disable socket communication.

--dump¶: Dump all received data to stdout and don’t use the input port.

Journal¶
