I am struggling a bit here and hoping for some guidance. I am using Discovery 18.104.22.168
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:
I would like to be able to read the contents of that file and place new attributes to the host.
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.
