scqcv

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. Figure 5‑19 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 stream information. Positioning the mouse over the parameter cell a ToolTip indicates more detailed information for the selected parameter. Typing a regular expression in the “StreamIDFilter” text entry field will result 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.

Figure 5-20 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 will result in a stream code filter, only displaying the matching stream codes.

The compact status overview allows a quick impression of the present status of all received streams (Fig. 5-21). Functionality is equal to the status overview grouped by network. You can switch between compact view and network seperated view by clicking the checkbox in the bottom line.

Options

scqcv supports commandline options as well as configuration files (scqcv.cfg).

Commandline

Only the default application class options are available (see chapter 5.2.2 for details).

Configuration

Users configuration file: $HOME/.seiscomp3/scqcv.cfg

plugins = <list>
List of plug-ins to load. Each plug-in enables a certain QC parameters to be displayed.
plugins.default.expire = <double>
Default time in seconds, how long a value is displayed in scqcv if no update is received. Setting to 0 means, show value until updated.
plugins.default.goodInterval = <double, double>
Default thresholds in between that a QC parameter value is defined as “good”. Each QC plug-in should define its own threshold.
plugins.default.useAbs4good = <flag>
Default sorting behavior. Setting to 1 (“True”) means handle positive and negative values equally while sorting, i.e. use absolute values for sorting but display real values (e.g.: -1, 1, 2, 3, -4, 5, -8, 8, 9, 10, ...).
plugins.qcplugin_spike.expire = <integer>
Time in seconds, how long a spike is displayed in scqcv if no update is recieved. Setting to 0 means, show spike until updated.
plugins.qcplugin_spike.goodInterval = <double, double>
Thresholds for amplitude anomalies in between that it is no ‘spike’.
plugins.qcplugin_gap.expire = <integer>
Time in seconds, how long a gap is displayed in scqcv if no update is recieved. Setting to 0 means, show gap until updated.
plugins.qcplugin_gap.goodInterval = <double, double>
Thresholds for time interval in seconds in between that it is no ‘gap’.
plugins.qcplugin_offset.useAbs4good = <flag>
Sorting behavior for offset validation. Setting to 1 (“True”) means handle positive and negative values equally while sorting, i.e. use absolute values for sorting but display real values. (default is 1)
plugins.qcplugin_offset.goodInterval = <double, double>
Thresholds for offset in between that it is “good”.
plugins.qcplugin_delay.goodInterval = <double, double>
Thresholds for delay in seconds in between that it is “good”.
plugins.qcplugin_latency.goodInterval = <double, double>
Thresholds for latency in seconds in between that it is “good”.
plugins.qcplugin_timing.goodInterval = <integer, integer>
Interval for the miniseed timing quality parameter to have “good” timing quality.
plugins.qcplugin_rms.goodInterval = <double, double>
Thresholds for the RMS value in between that the data quality is “good”.

Example of scqcv.cfg: 

 connection.subscription = QC
 plugins = qcplugin_delay, qcplugin_latency, qcplugin_timing, qcplugin_rms, qcplugin_offset, qcplugin_gap, qcplugin_spike
 plugins.default.expire = 0
 plugins.default.goodInterval = 0.0, 99E99
 plugins.default.useAbs4good = 0
 plugins.qcplugin_spike.expire = 600
 plugins.qcplugin_spike.goodInterval = 0.0, 0.0
 plugins.qcplugin_gap.expire = 600
 plugins.qcplugin_gap.goodInterval = 0.0, 0.0
 plugins.qcplugin_offset.useAbs4good = 1
 plugins.qcplugin_offset.goodInterval = 0.0, 550E3
 plugins.qcplugin_delay.goodInterval = 0.0, 60.0
 plugins.qcplugin_latency.goodInterval = 0.0, 300.0
 plugins.qcplugin_timing.goodInterval = 50, 100
 plugins.qcplugin_rms.goodInterval = 10.0, 10E6
