Jay Buffington created AURORA-1320:
--------------------------------------
Summary: when instance is running in docker container, thermos
observer reports 0 resources
Key: AURORA-1320
URL: https://issues.apache.org/jira/browse/AURORA-1320
Project: Aurora
Issue Type: Bug
Components: Docker, Thermos
Reporter: Jay Buffington
To see the problem start a job inside a docker container and view the
task/instance page. You'll cpu/ram/disk all at zero regardless of their actual
usage.
I see errors like this in the thermos observer log:
{noformat}
W0513 18:41:39.415406 3564 process_collector_psutil.py:42] Error during
process sampling [pid=112]: process no longer exists (pid=112)
W0513 18:41:39.415612 3564 process_collector_psutil.py:76] Error during
process sampling: process no longer exists (pid=112)
W0513 18:41:39.513972 3564 process_collector_psutil.py:76] Error during
process sampling: no process found with pid 122
{noformat}
This is likely because observer is running in a different pid namespace than
the process. One solution would be for the runner to write out the pid
namespace it is running in to the checkpoint and then have observer enter that
namespace while sampling.
Or we can just get rid of the observer?
