Apply the same restrictions like in monitoring module about icingaweb2-module-cube

[Thomas-Gelf]

This would require us to duplicate some logic from the monitoring module combined with reading/evaluating monitoring restrictions. The Cube has initially been designed as a drill-down tool for power users and not as a visualization tool for restricted users. I'm well aware of the fact that quite some installations use the cube for custom dashboards, so adding the possibility to grant restricted access would be a nice feature.

Played around a bit while figuring out how this entire ROLLUP works. An early prototype query looks like this:

SELECT rollup.env,
       rollup.location,
       rollup.department,
       rollup.hosts_cnt,
       rollup.hosts_nok,
       rollup.hosts_unhandled_nok
FROM (SELECT sub.env,
             sub.location,
             sub.department,
             SUM(hosts_cnt)           AS hosts_cnt,
             SUM(hosts_nok)           AS hosts_nok,
             SUM(hosts_unhandled_nok) AS hosts_unhandled_nok
      FROM (SELECT c_env.varvalue                                        AS env,
                   c_location.varvalue                                   AS location,
                   c_department.varvalue                                 AS department,
                   COUNT(*)                                              AS hosts_cnt,
                   SUM(CASE WHEN hs.current_state = 0 THEN 0 ELSE 1 END) AS hosts_nok,
                   SUM(CASE
                           WHEN hs.current_state != 0 AND hs.problem_has_been_acknowledged = 0 AND

                           ELSE 0 END)                                   AS hosts_unhandled_nok
            FROM icinga_objects AS o
                     INNER JOIN icinga_hosts AS h ON o.object_id = h.host_object_id AND o.is_active = 1
                     LEFT JOIN icinga_hoststatus AS hs ON hs.host_object_id = h.host_object_id
                     LEFT JOIN icinga_customvariablestatus AS c_env
                               ON c_env.varname = 'Env' AND c_env.object_id = o.object_id

                LIMIT 1
                )
            GROUP BY c_env.varvalue, c_location.varvalue, c_department.varvalue
          ) AS sub
      GROUP BY (env), (location), (department)

ORDER BY (rollup.env IS NOT NULL) ASC, rollup.env ASC, (rollup.location IS NOT NULL) ASC, rollup.location ASC,

Or with a CTE, though that's roughly 50% slower: (With a dataset of ~600 hosts and ~11k services)

    SELECT h.host_id
    FROM icinga_objects as so

             INNER JOIN icinga_hosts as h on h.host_object_id = s.host_object_id
    WHERE so.is_active = 1 and so.objecttype_id = 2 and ss.current_state != 0
    GROUP BY h.host_id
)
