Component configuration recommendations for horizontal scaling

Based on the recommended hardware sizes, you might need to change the configurations of various product components to make optimum use of available resources.

The following table provides a list of the configuration properties, their locations, and the recommended values for the properties for each setup.

Use the following table in conjunction with the recommendations provided in the horizontal sizing recommendations.

In the table, the configuration location paths must be preceded by one of the following environment variables:

Windows: %BMC_ITDA_HOME%
Linux: $BMC_ITDA_HOME

Note

When you change any of the following properties, ensure that you re-start the corresponding service for the particular component and any dependent services. For example, the wrapper.java.initmemory property defines the initial memory required for the Indexer, so when you change this property value, ensure that you re-start the Indexer.

For more information about starting or stopping services and service dependencies, see Starting or stopping product services.

Ensure that you make the same configuration changes for components of the same type. For example, if you change certain configurations for the Indexer, and you have multiple instances of Indexers deployed, ensure that you make the change for all Indexers in your environment.

Oops, it seems that you need to place a table or a macro generating a table within the Table Filter macro.

Indexer	Number of shards per index
Indexer	index.number_of_shards Read more... These changes are required only for the master Indexer installed on the primary node. Tip: A shard is a way of splitting a large amount of data into multiple portions, where each portion is called a shard. Shards also provide a way of evenly balancing data indexed across multiple Indexer instances. Notes: Any changes regarding the number of shards are applied only to the newly created indices. Modifying the value in the dynamic_template_1.json file will work only when you start the Indexer for the first time. After the first startup, this value can be changed by using the indexertemplates CLI command.	With one Indexer instance: 4 With two Indexer instances: 8 With three Indexer instances: 12	With one Indexer instance: 4 With two Indexer instances: 8 With three Indexer instances: 12 With four Indexer instances: 16 With five Indexer instances: 20 With six Indexer instances: 24 With seven Indexer instances: 28
Indexer	\conf\indexer\dynamic_template_1.json
Indexer	Indexing request timeout (in milliseconds)
Indexer	indexing.request.timeoutmillis Read more... At the time of adding multiple Indexers in your environment, this property must be adjusted to a lower value. Doing this can enable quicker recovery if any of the Indexer nodes go down.	30,000	5,000
Indexer	\station\collection\custom\conf\agent.properties	30,000	5,000
