Thresholds
| Anchor | ||||
|---|---|---|---|---|

The following table lists performance threshold rules that have default thresholds that might require additional tuning to suit your environment. Evaluate these rules to determine whether the default thresholds are appropriate for your environment. If a default threshold is not appropriate for your environment, you should obtain a baseline for the relevant performance counters, and then adjust the thresholds by applying an override to them.
