An implementation group is a group of Zabbix hosts that assemble hosts according to a certain gathering criterion (administrative region, group of schools, type of educational application). Zone indicators are “calculated and aggregated” across all the platforms recorded in the area, and are based on the individual indicators of each participating platform.

• Type: Aggregated measurement.
• Definition: Counts the average number of course modules per site.
• Examination range: Sample.

• Examination range: Sample.
• Key: moodle.area.percentofinstancesused
• Formula: 100*sum(last_foreach(/*/moodle.general.started?[ group=“{ZONE.HOSTGROUP}”))/sum(last_foreach(/*/moodle.general.instance?[ group=“{ZONE.HOSTGROUP}”])

• Formula: grpsum[“{ZONE.CURRENT}”, “moodle.courses.all”, last]

• Type: Calculated measurement
• Definition: Counts the total number of administrator connections and particular power roles (separate users) of the zone. The definition of users with special power depends on the choice of model for the detection of roles.

• Formula: grpsum[“{ZONE.CURRENT}”, “moodle.users.dailydistinctstudentlogins”, last]

• Type: Calculated measurement
• Definition: Counts the total number of connections of the teacher staff (separate users) of the area. The definition of teaching staff depends on the choice of model for role detection.

• Type: Calculated measurement
• Definition: Counts the total number of connections (non-unique users, all roles combined).
• Sampling frequency: Daily.
• Examination range: 1 day.
• Formula: grpsum[“{ZONE.CURRENT}”, “moodle.users.dailyogins”, last]
