Hi,
possibly one of approaches would be to create user-defined metric that checks alerts and their acknowledgement
periodically (let's say every 2,4 hours). You might use the following SQL:
with sql_targets as (
  select * from (
    select target_type, target_name, metric_name, column_label, key_value, current_value, collection_timestamp,
    row_number() over(partition by target_name, metric_name, column_label order by collection_timestamp) rn,
    count(1) over(partition by target_name, metric_name, column_label) cnt,
    round((sysdate - collection_timestamp), 0) days
    from mgmt$alert_current c
    where 1=1
    and alert_state in('Critical')
  ) where rn = cnt
sql_notes as (
  select n.target_type, n.target_name, n.metric_name, n.column_label, n.key_value, annotation_message msg, annotation_type typ,
  decode(annotation_type, 'ACKNOWLEDGED', 1, 0) acked,
  row_number() over(partition by n.target_type, n.target_name, n.metric_name, n.column_label order by annotation_timestamp) rn,
  count(1) over(partition by n.target_type, n.target_name, n.metric_name, n.column_label) cnt, t.collection_timestamp, annotation_timestamp
  from mgmt$alert_annotations n, sql_targets t
  where 1=1
  and t.target_type = n.target_type
  and t.target_name = n.target_name
  and t.metric_name = n.metric_name
  and t.column_label = n.column_label
  and t.key_value = n.key_value
  and n.annotation_timestamp >= t.collection_timestamp
select target_type, target_name, metric_name, column_label, key_value, count(*), max(acked), min(acked), min(annotation_timestamp),
max(annotation_timestamp) from sql_notes
group by target_type, target_name, metric_name, column_label, key_value
having max(acked) = 0;
HTH,
