Hi, I have been trying to understand the working of resource tracker. I understand that it is responsible to retrieve the data from the host and save it to the database. What I am not able to figure out is how exactly the compute node table is populated for the first time? Because after that resource tracker compare the data and update the changes. Again, does resource tracker work periodically? or is it triggered when an instance is spawned or deleted? Thanks. ~Peeyush Gupta -------------- next part -------------- An HTML attachment was scrubbed...
