1.1.1

This release just updates some third-party dependencies.

1.1.0

This release includes the following changes:

• The query for the standard metric wait_class has been updated so that it will work in both container databases and pluggable databases, including in Oracle Autonomous Database instances. Note that this query will not return any data unless the database instance is under load.
• Support for reading the database password from OCI Vault has been added (see details)
• Log messages have been improved
• Some dependencies have been updated

1.0.0

The first production release, v1.0, includes the following features:

• A number of standard metrics are exposed,
• Users can define custom metrics,
• Oracle regularly reviews third-party licenses and scans the code and images, including transitive/recursive dependencies for issues,
• Connection to Oracle can be a basic connection or use an Oracle Wallet and TLS - connection to Oracle Autonomous Database is supported,
• Metrics for Oracle Transactional Event Queues are also supported,
• A Grafana dashboard is provided for Transacational Event Queues, and
• A pre-built container image is provided, based on Oracle Linux, and optimized for size and security.

Note that this exporter uses a different Oracle Database driver which in turn uses code directly written by Oracle to access the database. This driver does require an Oracle client. In this initial release, the client is bundled into the container image, however we intend to make that optional in order to minimize the image size.

The interfaces for this version have been kept as close as possible to those of earlier alpha releases in this repository to assist with migration. However, it should be expected that there may be breaking changes in future releases.
