The information disposed by qmgr -c "p s " , pbsnodes -av , qstat -fx , qstat -anws1 are in the memory. Any other attributes you change on any object is stored in database immediately - like form qmgr Node states are not updated in the database, since they are transient in nature, it is not stored in the database. 1. you can get the real time job information by running qstat -fx , tracejob , pbs\_dtj 2. You can use the PBS Libraries and develop code which suits your requirement , plese follow the guide [High-performance Computing (HPC) and Cloud Solutions | Altair](https://www.pbsworks.com/pdfs/PBSProgramGuide18.2.pdf) > [@smilezy](#): > > I want to develop a cluster management system, including job management, resource management, etc.How do I get the job information in real time during the development process? Most of the Cluster management system have PBS Pro OSS integrated. Could you please explain what you would like to achieve, so that other experienced community members might contribute their suggestions. --- _[View the full topic](https://community.openpbs.org/t/how-to-aggregate-heterogeneous-entire-clusters-into-one-big-cluster-for-cross-cluster-job-submission/1217)._
