Also need to set memory.totalbytes
as node attributes when its configured via MemoryMB, and it should be converted to bytes

Replace comment with MemoryMB is the default node total memory in megabytes if it..
, would rather make the documentation explicit though the variable name is a clue.

Rename the config var memory_total_mb
here for the property to make it really explicit what the unit is, and to match cpu_total_compute

Instead of modifying the base test fixture, add a new hcl test case file that has this property set. This is so that we can exercise the default(total_memory not set) in the basic tests.

This is only a parsing test. It checks that the hlc file is properly converted to the data structure. This is never going to run the detection of memory on the platform.
If the memory_total_mb
is not set however, we should see a value set to 0
here instead.

yes that's what I mean - let it assert 0 when total_memory is not set for basic.hcl.

This checks merging two configuration data structure works. Here we check that the values (thaty are arbitrary) are overriden by the other values (those below at line 231 probably)

@mildred thanks for the PR. I added some review comments

Thank you for the quick review. Here is the pull request updated. Changes:
The test case in command/agent/config_test.go is modified because this test checks that two configuration structure can be merged together and that one set of value will replace the other set of values. Here the MemoryMB key was added so it is checked as well and the values are arbitrary for that test. |
Allow to set the total memory of an agent in its configuration file. This can be used in case the automatic detection doesn't work or in specific environments when memory overcommit (using swap for example) can be desirable.

Closing this in favor of PR #4052 which addresses the merge conflict |
thank you |
