Get started

Overview

Oracle Exadata extension connects to your Exadata devices and collects Exadata characteristics published by the Oracle Prometheus exporter. Metrics collected are continuously analyzed on Dynatrace platform, leveraging topological Exadata model that the extension maintains. Unified analysis screens offer insight into health and performance of the Exadata platform, including storage server and its components, such as flash cache, cell disks, and grid disks. Out of the box alerts notify on critical issues with the Exadata resources, including memory, CPU and I/O latency.

This extension is intended for users, who

Look to reliably monitor Exadata components and resource utilization with comprehensive dashboards and screens
Want to take pre-emptive measures to avoid service degradations rooting down to the Exadata resources oversubscription
Want to leverage rich observability signals provided out-of-the-box by the Exadata Prometheus exporters
Use Dynatrace for infrastructure monitoring and look to extend Dynatrace insights into the Exadata tier of their end-to-end infrastructure

Use cases

Integrated operational monitoring of the infrastructure, including Exadata
Early alerting on anomalies mounting in Exadata resource usage patterns
Root cause analysis of the Exadata bottlenecks, in the light of the entire application and infrastructure landscape observed by Dynatrace

Requirements

Follow the instructions for Using Real-Time Insight in the Oracle Exadata System Software User's Guide to configure metric stream for each type of server you want to monitor. Use the following script in DBMCLI on Database Servers (including VMs) and CELLCLI on Storage Servers to create a user with the appropriate privileges to consume the metrics. You need to perform this operation on every server you want to monitor.

CREATE ROLE realtime_collector
GRANT PRIVILEGE LIST ON METRICSTREAM ALL ATTRIBUTES WITH ALL OPTIONS TO ROLE realtime_collector
CREATE USER realtime_collector PASSWORD="password" ### Don't forget to change this password
GRANT ROLE realtime_collector to user realtime_collector

Compatibility information

Network access from a Dynatrace ActiveGate to the Exadata endpoints specified in the Get started section
Oracle Exadata System Software 22.1.0+
- This Extension uses API introduced in Exadata System Software 22.1.0
- Your Exadata Database Machine and Exadata Storage Server would carry the same version number as the Exadata System Software indicates
Note that this extension does not support ExaCC

Activation and setup

Activate the extension in your Dynatrace environment web UI using the in-product Hub and choose Monitor remotely.
Provide the required Prometheus exporter endpoint configuration:
Endpoint for storage servers: https://server-name/metricstream/list?stream=true
Endpoint for database servers using port 7879: https://server-name:7879/metricstream/list?stream=true
Use Basic authentication with the user realtime_collector and the password set in DBMCLI and CELLCLI.
For one Exadata system, create one extension configuration and configure Exadata endpoints for individual servers and cells within it. If you have multiple Exadata systems, create a configuration for each Exadata system and differentiate the Exadata system via the "Fleet" field.

Licensing and cost

There is no charge for obtaining the extension, only for the data that the extension ingests. The details of license consumption will depend on which licensing model you are using. This will either be Dynatrace classic licensing or the Dynatrace Platform Subscription (DPS) model.

Metrics

License consumption is based on the number of metric data points ingested. The following formula will provide approximate annual data points ingested assuming all feature sets are enabled.

(
    ( 19 * the number of servers )
  + ( 10 * the number of servers * the number of disks on the server )
  + ( 6  * the number of servers * the number of network interfaces on the server )
  + ( 12 * the number of database servers )
  + ( 1  * the number of database servers * the number of file systems on the DB server )
  + ( 1  * the number of cell servers * the number of file systems on the cell server )
  + ( 25 * the number of cell servers * the number of disks on the cell server )
  + ( 99 * the number of cell servers )
  + ( 16 * the number of cell servers * the number of databases on the cell server )
  + ( 16 * the number of cell servers * the number of pluggable databases on the cell server )
  + ( 5 * the number of cell servers * the number of DB/PDB * the number of consumer groups on the DB/PDB )
  + ( 2 * the number of category plans * the number of cell servers )
  + ( 2 * the number of IP addresses in queue )
  + ( 7 * the number of servers * (4 * the number of ROCE interfaces on the server) )
  + ( 6 * the number of cell servers * (2 * the number of cell disks on the cell server) )
) * 60 minutes * 24 hours * 365 days data points per year

Classic licensing

In the classic licensing model, metric ingestion will consume Davis Data Units (DDUs) at the rate of .001 DDUs per metric data point. Multiply the above formula for annual data points by .001 to estimate annual DDU usage.

Feature sets

When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly the extension has to collect at least one metric after the activation.

In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.

All metrics that aren't categorized into any feature set are considered to be the default and are always reported.

A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.

FAQ

This extension does not support monitoring ExaCC (Exadata Cloud at Customer).

For more information and potential alternatives, see OCI monitoring services by Oracle. Oracle says that Metrics for Exadata database service can be emitted to the OCI monitoring services. Dynatrace's Oracle Connector Hub Signals Ingest can consume metrics from the Connector Hub. Note: this answer is a digest of the publicly available documentation; this route hasn't been tested and verified by Dynatrace.

Exadata metric keys have a self-explanatory structure. Knowing it, you will always be able to understand what specific metric represents, exactly, even if its name or description looks similar to other available metrics.

Key to deciphering Exadata metric names:

The value of the name attribute is a composite of abbreviations. The attribute value starts with an abbreviation of the object type on which the metric is defined:

CD_ (cell disk)
CG_ (IORM consumer group, database-qualified)
CL_ (cell)
CT_ (IORM category)
DB_ (IORM database-level)
FC_ (flash cache)
FL_ (flash log)
GD_ (grid disk)
IORM (Input Output Resource Management)
N_ (network, IBPORT, HOST_INTERCONNECT)
PDB_ (IORM pluggable database)
SIO_ (Smart IO)

After the abbreviation of the object type, most of the name attributes contain one of the following combinations to identify the operation:

IO_BY (I/O amount)
IO_RQ (number of I/O requests)
IO_TM (I/O latency)
IO_WT (I/O wait time)
FC_IO_BY (Flash cache I/O amount)
FC_IO_RQ (Flash cache I/O requests)
FD_IO_BY (Flash disk I/O amount)
FD_IO_RQ (Flash disk I/O requests)
FD_IO_TM (Flash disk latency)
FD_IO_UTIL (Flash disk utilization percentage)

Next, in the name could be

_R (for read) or
_W (for write).

Following that in the name attribute value there might be

_SM or _LG to identify small or
_LG to identify large blocks, respectively.

At the end of the name, there could be

_SEC to signify per seconds or
_RQ to signify per request.

For consumer group and category metrics, read or write details are omitted.

For example: CD_IO_RQ_R_SM is the number of requests to read small blocks on a cell disk. GD_IO_TM_W_LG is the microseconds of I/O latency writing large blocks on a grid disk.

Source: Exadata Database Machine User's Guide section DESCRIBE METRICDEFINITION.

You need to configure metric streams on each Exadata server you intend to monitor. Use DBMCLI utility on DB servers. Use CELLCLI utility on cell servers. Or use utilities designed to run administration commands across a number of servers (dcli, exadcli) - see Exadata Software Overview.

Metrics must be enabled for Real-Time Insight on the Exadata side. Most likely, metrics are enabled by default on your Exadata system. If they are not, enable metrics for Real-Time Insight with the command:

alter metricdefinition finegrained=enabled where finegrained=disable

You can check what metrics are enabled using command:

list metricdefinition where finegrained=enabled detail

The command returns a detailed list of metrics that are enabled for Real-Time Insight.
