Description

rs2caps uses the recordstream to feed data into caps.

Examples

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

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.

-l, --lockfile arg

Path to lock file.

--console arg

Send log output to stdout.

--debug

Execute in debug mode. Equivalent to --verbosity=4 --console=1 .

--trace

Execute in trace mode. Equivalent to --verbosity=4 --console=1 --print-component=1 --print-context=1 .

--log-file arg

Use alternative log file.

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

-a, --addr arg

Data output host in format host:port.

--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 exceeded a sync of the journal is forced.

--backfilling arg

Default: 0

Buffer size in seconds for backfilling gaps.

--mseed

Enable on-the-fly MiniSeed encoding. If the encoder does not support the inputtype of a packet, it will be forwarded. Re-encoding ofMiniSEED packets is not supported.

--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.

--max-future-endtime arg

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.

--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

-j, --journal arg

File to store stream states. Use an empty string to log to standard out.

-f, --flush arg

Flush stream states to disk every n seconds

--wait-for-ack arg arg

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

-w, --wait-for-last-ack arg

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

Status

--status-log

Log information status information, e.g., max bytes buffered.

--status-flush arg

Flush status every n seconds to disk.

Streams

-A, --add-stream arg

StreamID [net.sta.loc.cha] to add.

--id-file arg

File to read stream IDs from.

--passthrough

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

--begin arg

Start time of data time window.

--end arg

End time of data time window.

Polling

--poll

For non-streaming inputs polling can be used to simulate real-time streaming.

--poll-window arg

Time window in seconds to be used with polling.

--poll-interval arg

Time interval in seconds used for polling.

--poll-serial

Will request each channel seperately rather all channels in one request.
