Method Detail

addIndicesToAttributes

public static void addIndicesToAttributes(ResourcePath path,
                                          Map<String,String> attributes)

Extends the attribute map with indices used by the TimeseriesResourceStorageDao. A resource path of the form [a, b, c, d] will be indexed with:

• _idx1: (a, 4)
• _idx2: (a:b, 4)
• _idx3: (a:b:c, 4)

findResourcesWithMetricsAtDepth

public static org.opennms.newts.api.search.Query findResourcesWithMetricsAtDepth(ResourcePath path,
                                                                                 int depth)

Constructs a query used to find all of the resources that have one or more metrics at the given depth bellow the path. Requires resources to have been indexed using addIndicesToAttributes(org.opennms.netmgt.model.ResourcePath, java.util.Map<java.lang.String, java.lang.String>).

toResourceId

public static String toResourceId(ResourcePath path)

Converts a ResourcePath to a Newts resource id.

Parameters:

path - path to convert

Returns:

Newts resource id

toResourcePath

public static ResourcePath toResourcePath(String resourceId)

Converts a Newts resource id to a ResourcePath.

Parameters:

resourceId - Newts resource id

Returns:

path

toMetricName

public static String toMetricName(String resourceId)

Extracts the metric name from the resource id.

Parameters:

resourceId - Newts resource id

Returns:

metric name

createSampleForIndexingStrings

public static org.opennms.newts.api.Sample createSampleForIndexingStrings(org.opennms.newts.api.Context context,
                                                                          org.opennms.newts.api.Resource resource)

Creates a sample used to index string attributes. These should only be index and not be persisted.
