Here is my ansible playbook. I'm inputting a file to my playbook and if it finds keywords like "open" or "allowed" in the file, I'm asking it to increment the variable dbsuccesscount by 1.
- name: testing
set_fact: dbsuccescount={{ dbsuccescount | int + 1 }}
when: item | regex_search('OPEN') and item | regex_search('ALLOWED')
with_items: "{{ file_check.stdout_lines }}"
tags: dbstatus_success
- debug:
var: dbsuccescount
Increment works successfully like below (last success number is 107).
snippet of the output
ok: [localhost] => (item=OPEN,ALLOWED) => {
"ansible_facts": {
"dbsuccescount": "107"
},
"ansible_loop_var": "item",
"changed": false,
"item": "OPEN,ALLOWED"
However I would like to print this last value which is 107 from dbsuccesscount. How can we print/read it?
I tried running the below which doesn't work
debug: msg="{{ dbsuccescount }} | last "
expected result:
I want my output to look like below
the dbsucesscount is 107 --> which is the last incremented value

I think your code is correct as written. Here's a complete example:
- hosts: localhost
gather_facts: false
vars:
file_check:
stdout_lines:
- OPEN ALLOWED
- junk
- junk
- OPEN ALLOWED
- junk
- OPEN ALLOWED
tasks:
- name: testing
set_fact:
dbsuccesscount: "{{ dbsuccesscount | default(0) | int + 1 }}"
when: item | regex_search('OPEN') and item | regex_search('ALLOWED')
with_items: "{{ file_check.stdout_lines }}"
tags: dbstatus_success
- debug:
var: dbsuccesscount
Running this produces:
PLAY [localhost] ***************************************************************
TASK [testing] *****************************************************************
ok: [localhost] => (item=OPEN ALLOWED)
skipping: [localhost] => (item=junk)
skipping: [localhost] => (item=junk)
ok: [localhost] => (item=OPEN ALLOWED)
skipping: [localhost] => (item=junk)
ok: [localhost] => (item=OPEN ALLOWED)
TASK [debug] *******************************************************************
ok: [localhost] => {
"dbsuccesscount": "3"
}
PLAY RECAP *********************************************************************
localhost : ok=2 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
There are three matching lines, so the debug task is printing exactly what we expect.
Of course, you don't need a with_items loop to count the number of matching lines; you can use a filter instead:
- name: testing
set_fact:
dbsuccescount: "{{ file_check.stdout_lines | select('match', 'OPEN|ALLOWED') | length }}"
- debug:
var: dbsuccescount
This produces the same output.
