obspy.clients.filesystem.sds.Client.get_all_nslc¶

Client.get_all_nslc(sds_type=None, datetime=None)[source]¶

Return information on what streams are included in archive.

Note that this can be very slow on network file systems because every single file has to be touched (because available location codes can not be discovered from folder structure alone).

Parameters:	sds_type (str) Override SDS data type identifier that was specified during client initialization. datetime (UTCDateTime) Only return all streams that have data at specified time (checks if file exists that should have the data, i.e. streams might be returned that have data on the same day but not at exactly this point in time).
Return type:	list
Returns:	List of (network, station, location, channel) 4-tuples of all available streams in archive.
