Summary
As a Confluence administrator, you may need to know what users were mentioned in a specific page or space, and how many times.
There currently isn't a way to export this information directly from the Confluence via the UI.
Solution
The queries below use wildcard searching in order to locate page content that matches a specific pattern for macros. Due to the nature of wildcard searching, these queries may take a long time to execute, and it is recommended to carry these out in a clone of the production database rather than on the production environment itself to avoid any impact to the production environment.
Number of Mentioned Users in a Space per Page
This SQL statement should provide you a list of all the users mentioned on a specific page, with a counter of how many times that user was mentioned:
PostgreSQL
create or replace function regexp_count(text, text)
returns integer language sql as $$
select count(m)::int
from regexp_matches($1, $2, 'g') m
$$;
SELECT s.spacekey, c.title, um.user_key, um.lower_username, regexp_count(bc.body, CONCAT('<ac:link><ri:user ri:userkey="',um.user_key))
FROM user_mapping um
LEFT JOIN bodycontent bc ON bc.body LIKE CONCAT('%<ac:link><ri:user ri:userkey="',um.user_key,'%')
JOIN content c ON c.contentid=bc.contentid
JOIN spaces s ON c.spaceid=s.spaceid
WHERE c.contenttype ='PAGE'
AND c.prevver IS null
AND s.spacekey='<SPACEKEY>'Oracle
SELECT s.spacekey, c.title, um.user_key, um.lower_username, REGEXP_COUNT(bc.body, CONCAT('<ac:link><ri:user ri:userkey="',um.user_key))
FROM user_mapping um
LEFT JOIN bodycontent bc ON bc.body LIKE CONCAT('%<ac:link><ri:user ri:userkey="',CONCAT(um.user_key,'%'))
JOIN content c ON c.contentid=bc.contentid
JOIN spaces s ON c.spaceid=s.spaceid
WHERE c.contenttype ='PAGE'
AND c.prevver IS null
Modify the variable <SPACEKEY> for the space key value you want to search for.
List of Mentioned Users in a Space
A simpler way of list the user without knowing how many times they were mentioned, it will be the following:
PostgreSQL
SELECT DISTINCT um.lower_username
FROM user_mapping um
LEFT JOIN bodycontent bc ON bc.body LIKE CONCAT('%<ac:link><ri:user ri:userkey="',um.user_key,'%')
JOIN content c ON c.contentid=bc.contentid
JOIN spaces s ON c.spaceid=s.spaceid
WHERE c.contenttype ='PAGE'
AND c.prevver IS null
AND s.spacekey='<SPACEKEY>'Oracle
SELECT DISTINCT um.lower_username
FROM user_mapping um
LEFT JOIN bodycontent bc ON bc.body LIKE CONCAT('%<ac:link><ri:user ri:userkey="',CONCAT(um.user_key,'%'))
JOIN content c ON c.contentid=bc.contentid
JOIN spaces s ON c.spaceid=s.spaceid
WHERE c.contenttype ='PAGE'
AND c.prevver IS null
AND s.spacekey='<SPACEKEY>' Modify the variable <SPACEKEY> for the space key value you want to search for.
