.. highlight:: rst .. _fdsnws: ###### fdsnws ###### **Provide FDSN Web Services.** Description =========== fdsnws is a server that provides event and station information by FDSN Web Services (:cite:t:`fdsn`) from a SeisComP database and waveforms from a :ref:`global_recordstream` source. Also it may be configured to serve data availability information as described in the IRIS DMC FDSNWS availability Web Service Documentation (:cite:t:`iris-dmc`). .. caution:: If you expose the FDSN Web Service as a public service, make sure that the database connection is read-only. fdsnws will never attempt to write into the database. Service Overview ================ The following services are available: .. csv-table:: :header: "Service", "Provides", "Provided format" ":ref:`fdsnws-dataselect `", "time series data", "`miniSEED `_" ":ref:`fdsnws-station `", "network, station, channel, response metadata", "`FDSN Station XML `_, `StationXML `_, :term:`SCML`" ":ref:`fdsnws-event `", "earthquake origin and magnitude estimates", "`QuakeML `_, :term:`SCML`" ":ref:`ext-availability `", "waveform data availability information", "text, geocsv, json, sync, request (`fdsnws-dataselect `_)" The available services can be reached from the fdsnws start page. The services also provide an interactive URL builder constructing the request URL based on user inputs. The FDSN specifications can be found on :cite:t:`fdsn`. **URL** * http://localhost:8080/fdsnws If ``fdsnws`` is started, it accepts connections by default on port 8080 which can be changed in the configuration. Also please read :ref:`sec-port` for running the services on a privileged port, e.g. port 80 as requested by the FDSNWS specification. .. note:: If you decide to run the service on a different URL than ``localhost:8080`` you have to change the URL string in the ``*.wadl`` documents located under ``$DATADIR/fdsnws``. .. _sec-dataSelect: DataSelect ---------- * Provides time series data in miniSEED format * Request type: HTTP-GET, HTTP-POST URL ~~~ * http://localhost:8080/fdsnws/dataselect/1/builder * http://localhost:8080/fdsnws/dataselect/1/query * http://localhost:8080/fdsnws/dataselect/1/queryauth * http://localhost:8080/fdsnws/dataselect/1/version * http://localhost:8080/fdsnws/dataselect/1/application.wadl Example ~~~~~~~ * Request URL for querying waveform data from the GE station BKNI, all BH channels on 11 April 2013 between 00:00:00 and 12:00:00: ``http://localhost:8080/fdsnws/dataselect/1/query?net=GE&sta=BKNI&cha=BH?&start=2013-04-11T00:00:00&end=2013-04-11T12:00:00`` To submit HTTP-POST requests the command line tool ``curl`` may be used: .. code-block:: sh sysop@host:~$ curl -X POST --data-binary @request.txt "http://localhost:8080/fdsnws/dataselect/1/query" where *request.txt* contains the POST message body. For details read the FDSN specifications. Feature Notes ~~~~~~~~~~~~~ * ``quality`` parameter not implemented (information not available in SeisComP) * ``minimumlength`` parameter is not implemented * ``longestonly`` parameter is not implemented * Access to restricted networks and stations is only granted through the ``queryauth`` method * The data channels exposed by this service may be restricted by defining an inventory filter, see section :ref:`sec-inv-filter`. * **No** trimming of miniSEED records to requested time window -- This FDSNWS implementation returns the records as available in its data source, e.g., SDS archive. It is guaranteed that the requested time range is within the returned data (if available in the archive) but not that it is exactly the requested time range. FDSNWS does not trim and therefore re-encode miniSEED records. The rationale for that is that miniSEED records are probably further distributed and stored in other archives and we do not see the point in modifying them. Furthermore we do not want to increase the load on the web server with that extra processing step. Service Configuration ~~~~~~~~~~~~~~~~~~~~~ * Activate :confval:`serveDataSelect` in the module configuration * Configure the :ref:`global_recordstream` in the module's global configuration. If the data is stored in a local waveform archive the :ref:`rs-sdsarchive` provides fast access to the data. For archives on remote hosts use :ref:`rs-arclink` or :ref:`rs-fdsnws` instead. .. warning:: Requesting future or delayed data may block the :ref:`sec-dataSelect` service. Therefore, real-time :ref:`global_recordstream` requests such as :ref:`rs-slink` should be avoided. If :ref:`rs-slink` is inevitable make use of the ``timeout`` and ``retries`` parameters. E.g. set the :confval:`recordstream` to ``slink://localhost:18000?timeout=1&retries=0`` or in case of the :ref:`rs-combined` service to ``combined://slink/localhost:18000?timeout=1&retries=0;sdsarchive//home/sysop/seiscomp/var/lib/archive``. .. _sec-station: Station ------- * Provides network, station, channel, response metadata * Request type: HTTP-GET, HTTP-POST * Stations may be filtered e.g. by geographic region and time, also the information depth level is selectable * Optionally handles time-based conditional HTTP-GET requests as specified by `RFC 7232 `_. URL ~~~ * http://localhost:8080/fdsnws/station/1/builder * http://localhost:8080/fdsnws/station/1/query * http://localhost:8080/fdsnws/station/1/version * http://localhost:8080/fdsnws/station/1/application.wadl Example ~~~~~~~ * Request URL for querying the information for the GE network on response level: http://localhost:8080/fdsnws/station/1/query?net=GE&cha=BH%3F&level=response&nodata=404 Feature Notes ~~~~~~~~~~~~~ * To enable FDSNXML or StationXML support load the plugin ``fdsnxml``. The plugin is loaded by default configuration. * ``updatedafter`` request parameter not implemented: The last modification time in |scname| is tracked on the object level. If a child of an object is updated the update time is not propagated to all parents. In order to check if a station was updated all children must be evaluated recursively. This operation would be much too expensive. * ``formatted``: boolean, default: ``false`` * Additional values of request parameters: * format: * standard: ``[xml, text]`` * additional: ``[fdsnxml (=xml), stationxml, sc3ml]`` * default: ``xml`` The inventory exposed by this service may be restricted, see section :ref:`sec-inv-filter`. .. _sec-event: Event ----- * Provides earthquake origin and magnitude estimates * Request type: HTTP-GET * Events may be filtered e.g. by hypocenter, time and magnitude URL ~~~ * http://localhost:8080/fdsnws/event/1/builder * http://localhost:8080/fdsnws/event/1/query * http://localhost:8080/fdsnws/event/1/catalogs * http://localhost:8080/fdsnws/event/1/contributors * http://localhost:8080/fdsnws/event/1/version * http://localhost:8080/fdsnws/event/1/application.wadl Example ~~~~~~~ * Request URL for fetching the event parameters within 10 degrees around 50°N/11°E starting on 18 April 2013: http://localhost:8080/fdsnws/event/1/query?start=2018-06-01&lat=50&lon=11&maxradius=10&nodata=404 Feature Notes ~~~~~~~~~~~~~ * |scname| does not distinguish between catalogs and contributors, but supports agencyIDs. Hence, if specified, the value of the ``contributor`` parameter is mapped to the agencyID. The file ``@DATADIR@/share/fdsn/contributors.xml`` has to be filled manually with all available agency ids * Origin and magnitude filter parameters are always applied to preferred origin resp. preferred magnitude * ``updatedafter`` request parameter not implemented: The last modification time in |scname| is tracked on the object level. If a child of an object is updated the update time is not propagated to all parents. In order to check if a station was updated all children must be evaluated recursively. This operation would be much too expensive. * Additional request parameters: * ``includepicks``: boolean, default: ``false``, works only in combination with ``includearrivals`` set to ``true`` * ``includecomments``: boolean, default: ``true`` * ``formatted``: boolean, default: ``false`` * Additional values of request parameters: * format: * standard: ``[xml, text]`` * additional: ``[qml (=xml), qml-rt, sc3ml, csv]`` * default: ``xml`` .. _sec-avail: Data Availability ----------------- The data availability web service returns detailed time span information of what time series data is available at the DMC archive. The availability information can be created by :ref:`scardac` in the |scname| database from where it is fetched by fdsnws. The availability service is no official standard yet. This implementation aims to be compatible with the IRIS DMC availability FDSN Web Service (:cite:t:`iris-dmc`) implementation. * request type: HTTP-GET, HTTP-POST * results may be filtered e.g. by channel code, time and quality URL ~~~ * http://localhost:8080/ext/availability/1/extent - Produces list of available time extents (earliest to latest) for selected channels (network, station, location and quality) and time ranges. * http://localhost:8080/ext/availability/1/builder-extent - URL builder helping you to form your data extent requests * http://localhost:8080/ext/availability/1/query - Produces list of contiguous time spans for selected channels (network, station, location, channel and quality) and time ranges. * http://localhost:8080/ext/availability/1/builder - URL builder helping you to form your data time span requests * http://localhost:8080/ext/availability/1/version Examples ~~~~~~~~ * Request URL for data extents of seismic network ``IU``: http://localhost:8080/fdsnws/ext/availability/1/extent?net=IU * Further limit the extents to those providing data for August 1st 2018: http://localhost:8080/fdsnws/ext/availability/1/extent?net=IU&start=2018-08-01 * Request URL for continues time spans of station ``ANMO`` in July 2018: http://localhost:8080/fdsnws/ext/availability/1/query?sta=ANMO&start=2018-07-01&end=2018-08-01 .. note:: Use :ref:`scardac` for creating the availability information. Feature Notes ~~~~~~~~~~~~~ * The IRISWS availability implementation truncates the time spans of the returned data extents and segments to the requested start and end times (if any). This implementation truncates the start and end time only for the formats: ``sync`` and ``request``. The ``text``, ``geocsv`` and ``json`` format will return the exact time windows extracted from the waveform archive. The reasons for this derivation are: * performance: With the ``/extent`` query the ``text``, ``geocsv`` and ``json`` offer the display of the number of included time spans (``show=timespancount``). The data model offers no efficient way to recalculate the number of time spans represented by an extent if the extents time window is altered by the requested start and end times. The ``sync`` and ``request`` formats do not provided this counter and it is convenient to use their outputs for subsequent data requests. * by truncating the time windows information is lost. There would be no efficient way for a client to retrieve the exact time windows falling into a specific time span. * network and station epochs returned by the :ref:`sec-station` service are also not truncated to the requested start and end times. * truncation can easily be done on client side. No additional network traffic is generated. .. _sec-inv-filter: Filtering Inventories ===================== The channels served by the :ref:`sec-station` and :ref:`sec-dataSelect` services may be filtered by specified an INI file in the ``stationFilter`` and ``dataSelectFilter`` configuration parameter. You may use the same file for both services or define a separate configuration set. **Note:** If distinct file names are specified and both services are activated, the inventory is loaded twice which will increase the memory consumption of this module. .. code-block:: ini [Chile] code = CX.*.*.* [!Exclude station APE] code = GE.APE.*.* [German (not restricted)] code = GE.*.*.* restricted = false shared = true archive = GFZ The listing above shows a configuration example which includes all Chile stations. Also all not restricted German stations, with exception of the station GE.APE, are included. The configuration is divided into several rules. The rule name is given in square brackets. A name starting with an exclamation mark defines an exclude rule, else the rule is an include. The rule name is not evaluated by the application but is plotted when debugging the rule set, see configuration parameter ``debugFilter``. Each rule consists of a set of attributes. The first and mandatory attribute is ``code`` which defines a regular expression for the channel code (network, station, location, channel). In addition the following optional attributes exist: .. csv-table:: :header: "Attribute", "Type", "Network", "Station", "Location", "Channel" "**restricted**", "Boolean", "X", "X", "", "X" "**shared**", "Boolean", "X", "X", "", "X" "**netClass**", "String", "X", "", "", "" "**archive**", "String", "X", "X", "", "" A rule matches if all of its attributes match. The optional attributes are evaluated bottom-up where ever they are applicable. E.g. if a rule defines ``restricted = false`` but the restricted flag is not present on channel level then it is searched on station and then on network level. If no ``restricted`` attribute is found in the hierarchy, the rule will not match even if the value was set to ``false``. The individual rules are evaluated in order of their definition. The processing stops once a matching rule is found and the channel is included or excluded immediately. So the order of the rules is important. One may decided to specify a pure whitelist, a pure blacklist, or to mix include and exclude rules. If neither a matching include nor exclude rule is found, then channel is only added if no other include rule exists in the entire rule set. .. _sec-port: Changing the Service Port ========================= The FDSN Web service specification defines that the Service SHOULD be available under port 80. Typically |scname| runs under a user without root permissions and therefore is not allowed to bind to privileged ports (<1024). To serve on port 80 you may for instance * Run |scname| with root privileged (not recommended) * Use a proxy Webserver, e.g. Apache with `mod-proxy `_ module * Configure and use :ref:`sec-authbind` * Setup :ref:`sec-firewall` redirect rules .. _sec-authbind: Authbind ======== ``authbind`` allows a program which does not or should not run as root to bind to low-numbered ports in a controlled way. Please refer to ``man authbind`` for program descriptions. The following lines show how to install and setup authbind for the user ``sysop`` under the Ubuntu OS. .. code-block:: sh sysop@host:~$ sudo apt-get install authbind sysop@host:~$ sudo touch /etc/authbind/byport/80 sysop@host:~$ sudo chown sysop /etc/authbind/byport/80 sysop@host:~$ sudo chmod 500 /etc/authbind/byport/80 Once ``authbind`` is configured correctly the FDSN Web services may be started as follows: .. code-block:: sh sysop@host:~$ authbind --deep seiscomp exec fdsnws In order use ``authbind`` when starting ``fdsnws`` as |scname| service the last line in the ``~/seiscomp/etc/init/fdsnws.py`` have to be commented in. .. _sec-firewall: Firewall ======== All major Linux distributions ship with their own firewall implementations which are front-ends for the ``iptables`` kernel functions. The following line temporary adds a firewall rule which redirects all incoming traffic on port 8080 to port 80. .. code-block:: sh sysop@host:~$ sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to 8080 Please refer to the documentation of your particular firewall solution on how to set up this rule permanently. Authentication Extension ======================== The FDSNWS standard requires HTTP digest authentication as the authentication mechanism. The "htpasswd" configuration option is used to define the location of the file storing usernames and passwords of users who are allowed to get restricted data. Any user with valid credentials would have access to all restricted data. An extension to the FDSNWS protocol has been developed in order to use email-pattern-based access control lists, which is an established authorization mechanism in SeisComP3 (used by Arclink). It works as follows: * The user contacts an authentication service (based on eduGAIN AAI, e-mail, etc.) and receives a list of attributes (a token), signed by the authentication service. The validity of the token is typically 30 days. * The user presents the token to /auth method (HTTPS) of the dataselect service. This method is the only extension to standard FDSNWS that is required. * If the digital signature is valid, a temporary account for /queryauth is created. The /auth method returns username and password of this account, separated by ':'. The account is typically valid for 24 hours. * The username and password are to be used with /queryauth as usual. * Authorization is based on user's e-mail address in the token and arclink-access bindings. Configuration ------------- The authentication extension is enabled by setting the "auth.enable" configuration option to "true" and pointing "auth.gnupgHome" to a directory where GPG stores its files. Let's use the directory ~/seiscomp/var/lib/gpg, which is the default. * First create the direcory and your own signing key: .. code-block:: sh sysop@host:~$ mkdir -m 700 ~/seiscomp/var/lib/gpg sysop@host:~$ gpg --homedir ~/seiscomp/var/lib/gpg --gen-key * Now import GPG keys of all authentication services you trust: .. code-block:: sh sysop@host:~$ gpg --homedir ~/seiscomp/var/lib/gpg --import > ~/seiscomp/etc/fdsnws.cfg Usage Example ------------- A client like :ref:`fdsnws_fetch ` is recommended, but also tools like wget and curl can be used. As an example, let's request data from the restricted station AAI (assuming that we are authorized to get data of this station). * The first step is to obtain the token from an authentication service. Assuming that the token is saved in "token.asc", credentials of the temporary account can be requested using one of the following commands: .. code-block:: sh sysop@host:~$ wget --post-file token.asc https://geofon.gfz-potsdam.de/fdsnws/dataselect/1/auth -O cred.txt sysop@host:~$ curl --data-binary @token.asc https://geofon.gfz-potsdam.de/fdsnws/dataselect/1/auth -o cred.txt * The resulting file "cred.txt" contains username and password separated by a colon, so one can conveniently use a shell expansion: .. code-block:: sh sysop@host:~$ wget "http://`cat cred.txt`@geofon.gfz-potsdam.de/fdsnws/dataselect/1/queryauth?starttime=2015-12-15T16:00:00Z&endtime=2015-12-15T16:10:00Z&network=IA&station=AAI" -O data.mseed sysop@host:~$ curl --digest "http://`cat cred.txt`@geofon.gfz-potsdam.de/fdsnws/dataselect/1/queryauth?starttime=2015-12-15T16:00:00Z&endtime=2015-12-15T16:10:00Z&network=IA&station=AAI" -o data.mseed * Using the :ref:`fdsnws_fetch ` utility, the two steps above can be combined into one: .. code-block:: sh sysop@host:~$ fdsnws_fetch -a token.asc -s 2015-12-15T16:00:00Z -e 2015-12-15T16:10:00Z -N IA -S AAI -o data.mseed Logging ======= In addition to normal |scname| logs, fdsnws can create a simple HTTP access log and/or a detailed request log. The locations of log files are specified by "accessLog" and "requestLog" in fdsnws.cfg. Both logs are text-based and line-oriented. Each line of *access* log contains the following fields, separated by '|' (some fields can be empty): * service name; * hostname of service; * access time; * hostname of user; * IP address of user (proxy); * length of data in bytes; * processing time in milliseconds; * error message; * agent string; * HTTP response code; * username (if authenticated); * network code of GET request; * station code of GET request; * location code of GET request; * channel code of GET request; Each line of *request* log contains a JSON object, which has the following attributes: service service name userID anonymized (numeric) user ID for statistic purposes clientID agent string userEmail e-mail address of authenticated user if using restricted data auth True if user is authenticated (not anonymous) userLocation JSON object containing rough user location (eg., country) for statistic purposes created time of request creation status "OK", "NODATA", "ERROR" or "DENIED" bytes length of data in bytes finished time of request completion trace request content after wildcard expansion (array of JSON objects) Each trace object has the following attributes: net network code sta station code loc location code cha channel code start start time end end time restricted True if the data requires authorization status "OK", "NODATA", "ERROR" or "DENIED" bytes length of trace in bytes Both logs are rotated daily. In case of access log, one week of data is kept. Request logs are compressed using bzip2 and not removed. If trackdb.enable=true in fdsnws.cfg, then requests are additionally logged into SeisComP database using the ArcLink request log schema. Be aware that the number of requests in a production system can be rather large. For example, the GEOFON datacentre is currently serving between 0.5..1 million FDSNWS requests per day. .. _sec-fdsnws-related: Related Modules =============== :term:`GEOFON` maintains scripts for FDSNWS :cite:p:`fdsnws_scripts`: * The :program:`fdsnws_fetch` client is a convenient tool for requesting waveforms from a FDSN web service hosted by :term:`EIDA` nodes. * The :program:`fdsnws2sds` client is a tool for requesting waveforms from a FDSN web service hosted by :term:`EIDA` nodes and to store them into an :term:`SDS` archive.
