The Metrics Supported by the TimesTen Exporter

The TimesTen exporter supports the following metrics:

• TimesTen version
• Contents of the SYS.SYSTEMSTATS system table
• Contents of the SYS.MONITOR system table
• Contents of the SYS.V$HEAP_INFO system view
• Contents of the SYS.V$GRIDSTATS system view (for TimesTen Scaleout)
• Contents of the SYS.V$BOOKMARK system view
• Contents of the SYS.V$CKPT_HISTORY system view
• Results from the ttLogHolds built-in procedure
• Results from the ttPLSQLMemoryStats built-in procedure
• Results from the ttLatchStatsGet built-in procedure
• Results from the ttStatus and the ttGridAdmin utilities
• Operating system thread statistics for the TimesTen main daemon and sub-daemon threads
• Total size and allocated size (in bytes) of the file system space for the checkpoint files and the transaction log directories
• Metrics about the TimesTen exporter itself, including
  • Current memory consumption
  • Time to service the current metric request
  • Number of metric requests
  • Number of disallowed requests
  • Total time to service metric requests
  • Version of the exporter

See Overview of System Tables and Views in the Oracle TimesTen In-Memory Database System Tables and Views Reference for information on the TimesTen system tables and system views. See Built-In Procedures and Utilities for information on the TimesTen built-in procedures and the TimesTen utilities.

Some of the metrics may not return any information, depending on the configuration. Some of the metrics pertain only to TimesTen Classic and some only to TimesTen Scaleout. Note that with few exceptions, the TimesTen exporter does not publish metrics for the underlying operating system. You can use the Node Exporter distributed with Prometheus to collect that information. For information on the Prometheus Node Exporter, see https://prometheus.io/docs/guides/node-exporter/.

The following tables show the metric name, the metric type, and the metric description for each TimesTen exporter metric. The metrics are arranged in alphabetical order and expand across multiple tables:
