SeedLink monitor creating web pages
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 webpage generated by slmon every 3 minutes:
*/3 * * * * /home/sysop/seiscomp/bin/seiscomp check slmon >/dev/null 2>&1
The crontab entry can be generated and added automatically using the seiscomp script:
seiscomp print crontab | crontab -
