Waveform archive data availability collector. The URL to the waveform archive where all data is stored. Format: [service://]location[#type] "service": The type of the archive. If not given, "sds://" is implied assuming an SDS archive. The SDS archive structure is defined as YEAR/NET/STA/CHA/NET.STA.LOC.CHA.YEAR.DAYFYEAR, e.g. 2018/GE/APE/BHZ.D/GE.APE..BHZ.D.2018.125 Other archive types may be considered by plugins. Number of threads scanning the archive in parallel. Acceptable derivation of end time and start time of successive records in multiples of sample time. Maximum number of segments per stream. If the limit is reached no more segments are added to the database and the corresponding extent is flagged as too fragmented. Set this parameter to 0 to disable any limits. Line-based text file of form NET.STA.LOC.CHA defining available stream IDs. Depending on the archive type, size and storage media used this file may offer a significant performance improvement compared to collecting the available streams on each startup. Filters defined under `filter.nslc` still apply. Parameters of this section limit the data processing to either reduce the scan time of larger archives or to prevent deletion of availability information even though parts of the archive have been deleted or moved to a different location. Limit the processing by record time. Start of data availability check given as date string or as number of days before now. End of data availability check given as date string or as number of days before now. Limit the processing by stream IDs. Comma-separated list of stream IDs to process. If empty all streams are accepted unless an exclude filter is defined. The following wildcards are supported: '*' and '?'. Comma-separated list of stream IDs to exclude from processing. Excludes take precedence over includes. The following wildcards are supported: '*' and '?'. Parameters of this section control the rescan of data chunks. By default the last update time of the extent is compared with the record file modification time to read only files modified since the list run. If set to true all data chunks are read independent of their mtime. Only read chunks modified after specific date given as date string or as number of days before now. Only read chunks modified before specific date given as date string or as number of days before now. scardac [OPTION]... generic#help generic#version generic#config-file generic#plugins verbosity#verbosity verbosity#v verbosity#quiet verbosity#print-component verbosity#print-context verbosity#component verbosity#syslog verbosity#lockfile verbosity#console verbosity#debug verbosity#trace verbosity#log-file Do not scan the archive but generate test data for each stream in the inventory. Format: days,gaps,gapslen,overlaps,overlaplen. E.g., the following parameter list would generate test data for 100 days (starting from now()-100) which includes 150 gaps with a length of 2.5s followed by 50 overlaps with an overlap of 5s: --generate-test-data=100,150,2.5,50,5
