# km3mon
Monitoring facility for the KM3NeT neutrino detector.
## Requirements
- Python 3.5+
Every other dependency will be installed or updated during the `make` procedure
via the Python package manager `pip`.
## Usage
First, install (or update) the requirements by typing
make
Next, create a ``setenv.sh`` script according to the ``setenv_template.sh``
script and apply the detector settings. Here is an example configuration
```shell
#!/bin/bash
export DETECTOR_ID=43
export DAQ_LIGIER_IP=192.168.0.110
export DAQ_LIGIER_PORT=5553
export DETECTOR_MANAGER_IP=192.168.0.120
export MONITORING_LIGIER_PORT=55530
export WEBSERVER_PORT=8081
export LOGGING_PORT=8082
export DETX="KM3NeT_00000043_03062019_t0set-A02087174.detx"
export ROYFIT_TIMERES="data/time_residuals.csv"
export LIGIER_CMD="singularity exec /home/off1user/Software/Jpp_svn2git-rc9.sif JLigier"
export TAGS_TO_MIRROR="IO_EVT, IO_SUM, IO_TSSN, MSG, IO_MONIT"
Notice the `LIGIER_CMD` which in this case uses a Singularity image of Jpp.
The `DETX` needs to point to a recently calibrated DETX file otherwise the
live reconstruction will not work correctly.
For the weblog you need to download the latest version of `frontail`:
https://github.com/mthenw/frontail/releases
After that, use the following command to start the ``supervisor``, which
you only need to do once:
From now on ``supervisorctl`` is the tool to communicate with the monitoring
system. To see the status of the processes, use ``supervisorctl status``,
which will show each process one by one (make sure you call it in the
folder where you launched it):
```
$ supervisorctl status
ligiers:ligiermirror RUNNING pid 611, uptime 1 day, 7:55:09
ligiers:monitoring_ligier RUNNING pid 610, uptime 1 day, 7:55:09
logging:msg_dumper RUNNING pid 7466, uptime 1 day, 7:28:00
logging:weblog RUNNING pid 7465, uptime 1 day, 7:28:00
monitoring_process:ahrs_calibration RUNNING pid 19612, uptime 1 day, 1:20:32
monitoring_process:dom_activity RUNNING pid 626, uptime 1 day, 7:55:09
monitoring_process:dom_rates RUNNING pid 631, uptime 1 day, 7:55:09
monitoring_process:pmt_hrv RUNNING pid 633, uptime 1 day, 7:55:09
monitoring_process:pmt_rates RUNNING pid 632, uptime 1 day, 7:55:09
monitoring_process:rttc RUNNING pid 9717, uptime 10:55:53
monitoring_process:trigger_rates RUNNING pid 637, uptime 1 day, 7:55:09
monitoring_process:triggermap RUNNING pid 638, uptime 1 day, 7:55:09
monitoring_process:ztplot RUNNING pid 7802, uptime 1 day, 7:26:13
webserver RUNNING pid 29494, uptime 1 day, 0:34:23
```
The processes are grouped accordingly (ligier, monitoring_process etc.) and
automaticallly started in the right order.
You can stop and start individual services using ``supervisorctl stop
group:process_name`` and ``supervisorctl start group:process_name``
Since the system knows the order, you can safely ``restart all`` or just
a group of processes. Use the ``supervisorctl help`` to find out more and
``supervisorctl help COMMAND`` to get a detailed description of the
corresponding command.
To shut down the monitoring service completely, use ``make stop``.
## Configuration file
A file called `pipeline.toml` can be placed into the root folder of the
monitoring software (usually `~/monitoring`) which can be used to set
different kind of parameters, like plot attributes or ranges.
Here is an example `pipeline.toml`:
[WebServer]
username = "km3net"
password = "swordfish"
[DOMRates]
lowest_rate = 150 # [kHz]
highest_rate = 350 # [kHz]
[PMTRates]
lowest_rate = 1000 # [Hz]
highest_rate = 20000 # [Hz]
[TriggerRate]
interval = 300 # time inverval to integrate [s]
with_minor_ticks = true # minor tickmarks on the plot
[TriggerMap]
max_events = 5000 # the number of events to log
[ZTPlot]
min_dus = 1
ytick_distance = 25 # [m]
```
