Quality control view.


scqcv provides both, a brief overview of the seismometer network status and a detailed view of specific stream parameters. Quality Control (QC) parameters, determined by scqc and sent via messaging system, are received and displayed.

scqcv allows to interactively disable or to enable streams for automatic data processing based on the observed QC reports.

Detailed QC reports per station

Tabulator view of scqcv shows the tabular view of the QC report messages. Each QC parameter is shown in a column. The default sorting by stream code can be changed by pressing a header field of a parameter. A widget displaying the currently received waveform data is shown by pressing the cell with the streamID. Positioning the mouse over the parameter cell a ToolTip indicates more detailed information on the selected parameter. Typing a regular expression in the “StreamIDFilter” text entry field results in a stream code filter, only displaying the matching stream codes with QC parameter. Green colored fields indicate that the QC parameter values lie within the configured “good” interval. Red colors indicate that the QC parameters lie outside the tolerated value interval – this stream might have an issue. Click on the table header to sort by the selected value or drag the columns to another position. The order of the columns is controlled by parameter. By clicking on a streamID, the past waveforms are displayed at length configured by streamWidget.length.

To disable / enable a station click on the respective station field in the enabled column.

Station overview

Status overview of scqcv with a stream widget shows the status overview grouped by network code. The more the color varies to dark red, the worse the waveform data might be. A dark red color indicates a stream with high latency. Light to darker red represents a badness sum of related QC parameters. Colors are subject to be changed in near future. Pressing a stream code item opens a single line table with detailed information of the selected stream. Again it is possible to open a real time waveform widget by pressing the leading header field indicating the stream code.

Typing a regular expression in the bottom text entry field results in a stream code filter, only displaying the matching stream codes. Disabled stations are crossed out. Click on a stream field to view the detailed QC parameters where stations can also be enabled / disabled.

The compact status overview allows a quick impression of the present status of all received streams (Compact status overview of scqcv). Functionality is equal to the status overview grouped by network.

Switch between compact view and network seperated view by clicking the checkbox in the bottom line.


Compact status overview of scqcv


While some important parameters can be configured using scconfig the configuration of others is available by examples in the extensive default configuration of scqcv in @DEFAULTCONFIGDIR/scqcv.cfg@

Apply your setup to scqcv.cfg in @SYSTEMCONFIGDIR@ or in @CONFIGDIR@. If the parameters are not configured, the defaults configuration will be considered.

Message groups and QC parameters

Select the desired parameters from the list below. “#” disables a parameter.

connection.primaryGroup = QC
connection.subscription = QC, CONFIG

parameter =  "latency           : latency",\
                             "delay             : delay",\
                             "timing quality    : timing",\
                             "offset            : offset",\
                             "rms               : rms",\
                             "gaps count        : gap",\
                             "overlaps count    : overlap",\
                             "availability      : availability",\
                             "spikes count      : spike"
#                            "gaps interval     : gap",\
#                            "gaps length       : gap",\
#                            "spikes interval   : spike",\
#                            "spikes amplitude  : spike"
#                            "overlaps interval : overlap",\
                             "overlaps length   : overlap"

Stream selection

By default all streams configured by the global bindings will be displayed. To limit the streams or to use a specific list configure and streams.cumulative.

Example configuration or the AM network:

# List of channels to display. By default the global configuration is used
# which can be overwritten with this parameter. = AM.*.*.*

# Add new streams from WfQ automatically to the list of stream configured in
streams.cumulative = false

QC parameters configuration

Configure intervals, values and format and background colors for displayed QC parameters.

Example for the QC parameter timing quality referred to as timing:

timing.ranges = bad, inter, sane
timing.range.inter = 50.0, 90.0
timing.range.inter.count = -1
timing.range.inter.color = yellow
timing.range.sane = 90.0, 100.0
timing.format = int
timing.expire = 600
timing.useAbsoluteValue = false



scqcv inherits global options.


Type: list:string

List of QC paramters to be displayed in the details table. Read the scqc documentation for a list of available QC parameters and the default configuration of scqcv $SEISCOMP_ROOT/etc/defaults/scqcv.cfg for more examples.

Format: "Parameter name : Config name"

Example: "delay : delay","spikes count : spike","spikes amplitude : spike"

Type: list:string

List of channels to display. By default the global binding configuration is used which can be overwritten with this parameter.

Add new streams automatically to the streams configured in when waveform QC parameters are provided for these streams. Default is false.


streamWidget.* Control the stream widget which opens when clicking on a stream name in the detailed table.


Type: double

Unit: s
