Getting sum of gathered facts

A few weeks ago, you guys helped me get the sum of gluster healings occurring on our gluster volumes. So now I have 3 facts that have sums of each of our 3 volumes. I’d like to sum those now as its own fact, but its giving me the output as a string. How can I actually sum the 3 values?

  • name: Set volume healing facts
    set_fact:
    home_sum: “{{ home_heal_status|json_query(‘glusterfs.heal_info.no_of_entries’)|map(‘int’)|sum }}”
    nas_sum: “{{ nas_heal_status|json_query(‘glusterfs.heal_info.no_of_entries’)|map(‘int’)|sum }}”
    projects_sum: “{{ projects_heal_status|json_query(‘glusterfs.heal_info.no_of_entries’)|map(‘int’)|sum }}”

  • name: Get healing total
    set_fact:
    total: “{{ home_sum|int }} + {{ nas_sum|int }} + {{ projects_sum|int }}”

home_sum is 2, nas_sum is 0, and projects_sum is 0. So I’d assume that the sum would be 2, however what is being calculated for the fact “total” is “2+0+0”. I need the actual sum.

Thanks,

  - name: Get healing total
    set_fact:
      total: "{{ home_sum|int }} + {{ nas_sum|int }} + {{ projects_sum|int }}"

You go in and out of jinja templating, but the entire expression is
still a string.

home_sum is 2, nas_sum is 0, and projects_sum is 0. So I'd assume that the sum would be 2, however what is being calculated for the fact "total" is "2+0+0". I need the actual sum.

Doing the calculation entirely in jinja should work, i.e.:

total: "{{ home_sum|int + nas_sum|int + projects_sum|int }}"

- name: Set volume healing facts
set_fact:

nas_sum: "{{ nas_heal_status|json_query('glusterfs.heal_info.no_of_entries')|map('int')|sum }}"
projects_sum: "{{ projects_heal_status|json_query('glusterfs.heal_info.no_of_entries')|map('int')|sum }}"

- name: Get healing total
set_fact:
total: "{{ home_sum|int }} + {{ nas_sum|int }} + {{ projects_sum|int }}"

home_sum is 2, nas_sum is 0, and projects_sum is 0. So I'd assume that the sum would be 2, however what is being
calculated for the fact "total" is "2+0+0". I need the actual sum.

You are asking for separate calculations by using curly braces for each sum.

So please try something like: "{{ home_sum|int + nas_sum|int + projects_sum|int }}"

Try this

  - name: Get healing total
    set_fact:
      total: "{{ home_sum|int + nas_sum|int + projects_sum|int }}"

Thanks! That worked. I thought I had done that but I guess my syntax was just a little off. Works now.

I appreciate the quick responses!
