Hi All ,
I have to search for a pattern string in the various log files located in
some directory on the host. how we can use regex kind of a thing with
command module or may be some other useful ansible way i am not aware about.
here is my code which complains about vm*.log.
- name: Check whether vmware log file contains TDR
command: grep 'TDR_DUMP' '{{guest_vm_path}}/{{item}}/vm*.log'
with_items:
- '{{guest_list}}'
- '{{guest_name_poweredon}}'
ignore_errors: True
register: output
- debug:
var: output
- debug: msg="No TDR signature found"
when: output["results"][0].rc == 1 and
output["results"][1].rc == 1 and
output["results"][2].rc == 1
- debug: msg="Found the TDR signature"
when: output["results"][0].rc == 0 or
output["results"][1].rc == 0 or
output["results"][2].rc == 0
- debug:
var: output.stdout_lines
when: output["results"][0].rc == 0 or
output["results"][1].rc == 0 or
output["results"][2].rc == 0
