For example, power outage may be the actual root cause why some host is unreachable or some service is down. In this ”host is unreachable” and ”service is down” problems may be classified as the symptom problems of ”power outage” - the cause problem. 10 Symptom problems are grouped under the cause problem and marked

The new section is intended to give users a much clearer view of problems in comparison to the two Monitoring → Triggers and Monitoring → Events sections used for this purpose previously. 8 In a extract. For these purposes, the new version comes with a new concept of macro functions. Currently, two macro functions are supported: • regsub - substring extraction by a regular expression match (case number of identical messages sent and stored in the database. To deal with these issues there are two major improvements: • an optional maxdelay parameter for log monitoring items, which can be used to
