Currently (As of this writing, July 2021) there is no method or built-in report for all alarm policies; this would be considered an enhancement request.
It is possible to individually export alarm policies into JSON/XML format using the API, and this could be leveraged for some customized reporting but this would be outside the scope of support. The intention of this is to export policies from a pre-production environment and import them to production, so other uses would be considered unsupported (but it might be possible to do.)
The following SQL query might also be a good starting point - this is unsupported and provided *AS-IS* as an example only:
select PolicyMetric.name as "Policy Name", PolicyMetric.probeName as "Probe", PolicyMetric.qos, PolicyTarget.name AS "Group Name", PolicyThreshold.type as "Alarm Type", PolicyThreshold.operator, PolicyThreshold.value,
FROM Policy INNER JOIN
PolicyCondition ON Policy.id = PolicyCondition.policy_id INNER JOIN
PolicyMetric ON PolicyCondition.policyMetric_id = PolicyMetric.id INNER JOIN
PolicyTarget ON PolicyCondition.policyTarget_id = PolicyTarget.id INNER JOIN
PolicyThreshold ON PolicyCondition.id = PolicyThreshold.condition_id
Otherwise there is no single report for this.
