Saving Online Monitoring Data
The procedure for writing the data out is given in, e.g., Raid-to-Silo Transfer Strategy.
Once the DAQ writes out the data to the raid disk, cron jobs will copy the file to tape, and within ~20 min., we will have access to the file on tape at /mss/halld/$RUN_PERIOD/rawdata/RunXXXXXX.
All online monitoring plugins will be run as data is taken. They will be accessible within the counting house via RootSpy, and for each run and file, a ROOT file containing the histograms will be saved within a subdirectory for each run.
For immediate access to these files, the raid disk files may be accessed directly from the counting house, or the tape files will be available within ~20 min. of the file being written out.
Offline: Setup for a new run period
- Download the "monitoring" scripts directory from svn. For the gxprojN accounts, use the directory ~/monitoring/:
cd ~/ svn co https://halldsvn.jlab.org/repos/trunk/scripts/monitoring/cd monitoring/incoming
- Edit the job config file, ~/monitoring/incoming/input.config, which is used to register jobs in hdswif. A typical config file will look this:
PROJECT gluex TRACK reconstruction OS centos65 NCORES 24 # 24 = Entire node DISK 40 RAM 32 # 32 GB per node TIMELIMIT 8 JOBNAMEBASE offmon RUNPERIOD 2016-02 VERSION 01 OUTPUT_TOPDIR /cache/halld/offline_monitoring/RunPeriod-[RUNPERIOD]/ver[VERSION] # Example of other variables included in variable SCRIPTFILE /home/gxproj1/monitoring/incoming/script.sh # Must specify full path ENVFILE /home/gxproj1/env_monitoring_incoming # Must specify full path
- Create a new swif workflow:
~/monitoring/hdswif/hdswif.py create [workflow] -c ~/monitoring/incoming/input.config
- If not already running, the cron job can be launched by running:
crontab cron_incoming
