Description
|
||
|
|
===========
|
||
|
|
|
||
|
|
*slmon* collects waveform QC parameters from a configured :ref:`seedlink` Server
|
||
|
|
and creates static HTML websites for their visualization. :ref:`Station summeries<fig-slmon>` and
|
||
|
|
:ref:`per-station channels views<fig-slmon-stat>` are available.
|
||
|
|
|
||
|
|
Setup
|
||
|
|
=====
|
||
|
|
|
||
|
|
1. 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.
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
|
||
|
|
*/3 * * * * /home/sysop/seiscomp/bin/seiscomp check slmon >/dev/null 2>&1
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
The crontab entry can be generated and added automatically
|
||
|
|
using the seiscomp script:
|
||
|
|
|
||
|
|
.. code-block:: sh
|
||
|
|
|
||
|
|
seiscomp print crontab | crontab -
