Monitoring
We have developed a monitoring tool called Grid Load that allows to see the number of jobs in any given state. For more details please see the Readme.
Real Time Monitor
View the state of the grid !!! It's awesome ;-) Joking aside, this is a very useful tool to explain the grid to non-experts. Sometimes a picture does say more than 1000 words. Real Time monitor.

VO configuration
- The following LondonGrid-yaim-vo can be appended to the yaim configuration file in order to support the VOs recommended by GridPP. Beware that it assumes DPM_HOST to be your SE. The queue part also needs to be properly configured for your site. The contents of the vo.d directory is LondonGrid-vo.d.
- The LondonGrid-group.conf should also be correctly populated
