Hello,

I'm trying to install an NCPA agent inside a docker container and getting the error below. Can you please tell me how to fix this and if you have any recommendations for using NCPA (or something else) to monitor within a docker container?

Code: Select all

stderr] Traceback (most recent call last):

[stderr] File "/usr/local/lib/python2.7/site-packages/cx_Freeze-4.3.4-py2.7-linux-x86_64.egg/cx_Freeze/initscripts/Console.py", line 27, in <module>

[stderr] File "ncpa_posix_listener.py", line 6, in <module>

[stderr] File "/usr/local/lib/python2.7/site-packages/psutil/_pslinux.py", line 620, in disk_partitions

[stderr] OSError: [Errno 2] No such file or directory: '/etc/mtab'

Thanks!

You could create an empty mtab:

Code: Select all

touch /etc/mtab

This might also work:

Code: Select all

ln -s /proc/mounts /etc/mtab
