Dynatrace infrastructure monitoring is based on numerous built-in, predefined static thresholds. These thresholds relate to resource contentions like CPU spikes, memory, and disk usage. You can change these default thresholds by going to Settings > Anomaly Detection > Infrastructure in the Dynatrace menu.
For applications and services, you can disable automated baselining-based reference-value detection anytime and switch to user-defined static thresholds. If you set a static threshold for response time and error rate on an application or service level, events will be raised if the static threshold is breached. A slowdown event is raised if the static thresholds for either the median or the 90th percentile response times are breached.
Predefined static thresholds for hosts
|Hosts||Default static threshold|
|Memory event usage|
|Java out of memory|
Predefined static thresholds for networks
|Network||Default static threshold|
|Number of dropped packets|
|TCP connectivity for process|
Predefined static thresholds for disks
|Disk||Default static threshold|
|Low disk space|
|Slow running disks|
|Inodes number available|
As static thresholds don't adapt to changing environments and require too much manual effort, Dynatrace also offers intelligent, automated multi-dimensional baselining, which works out of the box, without manual configuration of thresholds. Most importantly, it adapts automatically to changes in traffic patterns.
