tegrastats report issue

When we use tegrastats to monitor TX2 status, we found below wired things.

  1. Why sometimes, only show CPU 1, not CPU [%X@Y] style?
  2. What is the max cached value?
  3. Our cached value vary frequently, what is standard for?

Hi,
Do you run ‘sudo tegrastats’? Also the interval is 1000ms by default. We don’t observe the strange behavior with the setting. Do you set smaller interval?

For information, please share your release version( $ head -1 /etc/nv_tegra_release )

Danell,

As you can see we enable swap space and also RAM usage already up to the max level. Is this relate with current issue?

sudo tegrastats --interval 5000

Hi,
Your prints look not right. The log of r28.1/TX2 should be:

Please run the tegrastats binary in r28.1.

We use tegra-l4t-r28.2.1.

tegrastats command use follow style.

tegrastats --help

As for the swap cache. You could refer to
http://www.linux-tutorial.info/modules.php?name=MContent&pageid=314

Our cached value vary frequently, what is standard for
It looks normal since your memory usage almost meets the 8GB. System start to use swap so swap cache value goes up.

Hi,
It shows your system is r28.1:

~$ head -1 /etc/nv_tegra_release 
# R28 (release), REVISION: 1.0, GCID: 9379712, BOARD: t186ref, EABI: aarch64, DATE: Thu Jul 20 07:59:31 UTC 2017

Suggest you check if you have system in r28.1 and kernel in r28.2.1. Or do clean re-flash through Jetpack to have a clean system.

DaneLLL,

I get what you mean.

Here is our status. Rootfs may still use JetPacke3.1 version, but source code is already switched to tegra-l4t-r28.2.1 with “source_syn.sh -k tegra-l4t-r28.2.1”

You mean we should also switch rootfs to JetPacke3.2?

Hi,
Yes, please match release version of packages.
