Instructions how to use data monitoring SW in the counting root.

Tool choice

There are several software tools you can use.

1. Monitor. This is the old good Monitor that has been used since long. It has been designed to be lightweight and fast. Because of that, reconstruction algorithms are simplified (compared to the OfflineSW) or completely missing. Hence reconstruction results (track fits for instance) may not be reliable. The Monitor is a good choice for low level (VFAT) investigations, but it is not recommended for real data quality monitoring (use DQM instead).

2. Automatic monitoring. This is just a script that runs the Monitor in background whenever a new raw-data file appears. Thus it can display a set of standard plots for the latest file without human intervention.

3. TotemDQM. This is the real data quality monitor. It is based on the OfflineSW, hence all results will be consistent with subsequent analyses. It might be a bit slower than the Monitor. It is a good choice if you wish to check the quality of your data. It has an improved GUI, therefore work with TotemDQM should be more comfortable than with Monitor (it can open several windows on several screens, for example).

Instructions for Monitor

Type these commands:

  1. ssh rp@TOTEM-CR-08
  2. cd Monitor/
  3. bash --rcfile environment_CR
  4. monitor/bin/monitor

For help on usage see Monitor user's manual.

Instructions for Automatic monitoring

Type these commands:

  1. ssh rp@TOTEM-CR-08
  2. cd Monitor/
  3. bash --rcfile environment_CR
  4. gv actual_snapshot.eps &
  5. ./periodicMonitor

Make sure that gv will watch the file - click on State in the menu and check the Watch file option.

The set of plots is shared with Monitor. To change it, open the Monitor and change the layout.

Instructions for TotemDQM

Type these commands:

  1. ssh rp@TOTEM-CR-08
  2. ce 311 (this loads the right environment settings)
  3. runTotemDQM

Then start with File/Open. For usage instructions see TotemDQM user's manual. Note that there is a number of standard plots sets prepared for you. To use the click on View/New tab from... and select the set you wish.
