Hi folks,

I am struggling a bit here and hoping for some guidance.  I am using Discovery 11.2.0.1

We have a file we want to read.  It is at /etc/bb-imageinfo

The contents of this file adhere to a format as follows:

BUILDOS=centos

BUILDVERSION=7-master

BUILDDATE=2017_11_29

BUILDID=b374

I would like to be able to read the contents of that file and place new attributes to the host.

Example

Image Build OS = centos

Image Build Version = 7-master

Image Build Date = 2017_11_29

Image Build ID = b374

This would allow us to see what image as VM was spun up as.

Something is not working here. I have double checked permission of the file and the file is present.  I am testing this on one machine.  Can any point out where I am going wrong?  I think I have to be close but something is not working for me.

I was looking through the eca logs as well.  I didn't see anything in there.  I wonder if my logging setup in the pattern is working.  I also set reasoning logs to debug prior to the last scan as well.

Any help would be appreciated.

The content of my pattern is here:

tpl 1.12 module AltusImage_Info_UNIX;

pattern AltusImageInfo_Unix 1.0

"""

This pattern reads a text file to do some additional discovery about the image for a Unix VM.
