SeedLink monitor creating web pages
slmon collects waveform QC parameters from a configured seedlink Server and creates static HTML websites for their visualization. Station summeries and per-station channels views are available.
Adjust the module configuration parameters of slmon to set the seedlink Server, the output directory for the created webpages and other parameters.
Create and adjust binding profiles and station bindings for slmon to activate the monitoring of the desired networks and stations.
Update the configuration of slmon
Start slmon. This step reads the QC parameters and creates the static webpage. The webpage is not automatically updated.
seiscomp update-config
seiscomp start slmon
Restart slmon in order to upate the webpage. The restart can be performed by a the regular system check scheduled by a crontab entry.
The example below shows a crontab entry to update the the webpage generated by slmon every 3 minutes:
*/3 * * * * /home/sysop/seiscomp3/bin/seiscomp check slmon >/dev/null 2>&1
A comprehensive example for monitoring many stations of a large number of networks is provided by GEOFON at GFZ Potsdam, Germany. A simple example of a website create by slmon is given in the figures below.
