Yes; if totalMemory > 2G, report totalMemory - 1G; otherwise, report
totalMemory/2.

Mesos agent (aka slave) estimates the memory available and advertises
all of it minus 1GB. If there is less than 2GB available, only half is

My bad, Seeing the 1002mb(~1024) number made me think the agent
was not able to get the memory estimates from the OS and
defaulting to the constant values.
The slave executes a `sysinfo` system call and populates the
memory numbers based on it. If you want a more fine-grained
control, try to specify it directly using the —resources flag as I
had mentioned earlier.

There seems to be some dynamicness to it. I just bumped the
memory for each VM up to 2.5GB and now mesos is offering 1.5GB on
it's slave. Is there some percentage value that I can set so that
more memory is available to mesos?

In case you don’t specify the resources via “—resources” flag
when you start your agent, it picks up the default values.
(Example: --resources="cpus:4;mem:1024;disk:20000”)
The default value for memory is here:
