This chapter details metric information collected for your TimesTen database to assist you in determining the efficiency and performance of your database.
Topics include:
Make sure you are on the TimesTen target page. For more information on navigating to the TimesTen target page, see "Navigating to the TimesTen target page".
There are 12 groups of metrics:
Some metrics have predefined warning and critical thresholds. You can modify and add new thresholds. The Oracle Enterprise Manager Cloud Control issues alerts and warnings when the values collected for the metrics surpass the set threshold.
Table 6-1 lists each metric and provides a description of the metric.
