Add slow control monitoring script

[adambrown1]

This adds the script updateSlowControl.py which can be used to make plots of the slow control parameters. For example, this plot is created for the high voltage:

In addition it makes a PHP status table which allows a quick check of whether the parameters are OK:

We display these plots on a web page using PHP code like the following:

<?php shell_exec("cp [PLOT_DIRECTORY]/*.png data_include/modulation/"); ?>
<?php shell_exec("cp [PLOT_DIRECTORY]/datatable.php data_include/modulation/"); ?>
<?php shell_exec("cp [PLOT_DIRECTORY]/datastat.php data_include/modulation/"); ?>

<?php include('data_include/modulation/datatable.php'); ?>

<a href="data_include/modulation/pressure1.png"><img width="840px" align="middle" class="zoomable"  src="data_include/modulation/pressure1.png" border="0"></a>

Provided the environment variables have been set up according to the instructions in the wiki (modulation:daq:enviromentvariables), you should be able to run this using a bash script with something like the following (best is, to add to the crontab and run regularly).

cd $MODEXP_DAQANA_DIR
/daqprocessor_single_calibrate.py $MODEXP_RAW_DATA_DIR/ -s -l -t=1
cd $MODEXP_ANALYSIS_DIR
python updateSlowControl.py

Very nice, I assume you based this on Joran's code?

As the proof is in the pudding, Jasper can you try it out here, if it works lets merge it.

We have been using this for quite some time in Zurich in fact. It would be nice for Jasper to try it, maybe we need to fix a bug to make it truly portable. 2017-11-02 11:56 GMT+01:00 P.A. (Sander) Breur <notifications@github.com>:

@Jaspernobelen Are you able to test this at Nikhef?
It would be good to know what I need to change, if anything, to make it fully portable.
