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,  
Harry

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 }}"

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

&nbsp;&nbsp;- name: Get healing total  
&nbsp;&nbsp;&nbsp;&nbsp;set\_fact:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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!
