Get metrics from the Stardog service in real time to:
The Stardog check is not included in the Datadog Agent package, so you need to install it.
For Agent v7.21+ / v6.21+, follow the instructions below to install the Stardog check on your host. See Use Community Integrations to install with the Docker Agent or earlier versions of the Agent.
Run the following command to install the Agent integration:
datadog-agent integration install -t datadog-stardog==<INTEGRATION_VERSION>
Configure your integration similar to core integrations.
Edit the stardog.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your Stardog metrics. See the sample stardog.d/conf.yaml for all available configuration options.
Run the Agent’s status subcommand and look for stardog under the Checks section.

| stardog.dbms.memory.native.max (gauge) | The maximum amount of native memory that the process is allowed to use outside of the JVM. This includes any buffers that are natively created by populated inside the JVM, as well as any memory which is natively allocated (like rocksdb) Shown as byte |

| stardog.dbms.memory.system.pinnedSize (gauge) | the current amount of memory which is 'pinned' by the operating system, and cannot be swapped out by the process. Note that only some operating systems support this; Operating systems which do not support the metric will report -1 for this value always Shown as byte |
| stardog.dbms.memory.system.regioncount (gauge) | The current OS-reported number of regions in use by this process. This number only applies to Operating systems which have a region-based memory system, like OS X (but not Linux or Windows). For operating systems which does not use regional memory, this number will be set to 1 Shown as unit |
| stardog.dbms.memory.system.rss (gauge) | The current OS-reported RSS(Resident Set Size) for this process. For more information on RSS, see this article Shown as unit |
| stardog.dbms.memory.system.rss.peak (gauge) | The OS-reported maximum RSS achevied by this process since it started. Shown as unit |
| stardog.dbms.memory.system.usageRatio (gauge) | The ratio of currently used memory to the total amount available to the process. Shown as fraction |
| stardog.dbms.memory.system.virtual (gauge) | The current OS-reported Virtual memory size for this process. Note that a large virtual size does not automatically equate to a large actual memory usage. For more information see this stackoverflow description. Shown as byte |
| stardog.kga.UriScheme.VirtualGraphName.triples (gauge) | Number of triples in the given virtual graph. Shown as unit |
| stardog.kga.dbname.ce.classname (gauge) | The number of entities of a particular class. Shown as unit |
