HI @anchen,

Thanks for joining the community forum. What agent did you install on the LInux host, NCPA? If so, make sure you have the correct token in your check command.

Here's the NCPA setup doc:

Hi benjaminsmith,

I use deploy agent to install NCPA agent.
Don't use manual install agent.
So I don't know root cause in where.


Thanks!
Andy
