Hi,

RTM has a number of daemons that run on the grid control server. These daemons collect data from the LSF operations (running jobs, machine status, performance metrics etc) but also read and write the LSF configuration files. A database receives all the collected data. An elaborate web interface allows you to view and change the configuration of your cluster and also shows the performance metrics collected in the database via RRDTool charts.

Although SAS is striving to surface all the functionality in the Environment Manager and Management Console (and will no doubt succeed in due time) I find RTM a valuable addition to the toolset of the grid administrator.

Beware if you want to install RTM on RHEL 7.2. The RTM distribution is not quite up to date to simple changes like MariaDB replacing MySQL. This throws off the installer big time.

Hi,

In any Grid Architechture, there is a master node which has all the master process. and Child Nodes which has all the child Process. Child process is always updating information to the master process which is then displayed as grid stats related to Nodes, jobs and their execution. In case any of these child process goes down, you would see these information displayed as UKNWN.

Then you would have to login to that node to troubleshoot further.

Hope this helps.

Thanks,

Anand!
