Example 1 with DciDataRow

use of org.netxms.client.datacollection.DciDataRow in project netxms by netxms.

the class NXCSession method getCollectedDataInternal.

/**
 * Get collected DCI data from server. Please note that you should specify
 * either row count limit or time from/to limit.
 *
 * @param nodeId     Node ID
 * @param dciId      DCI ID
 * @param instance   instance value (for table DCI only)
 * @param dataColumn name of column to retrieve data from (for table DCI only)
 * @param from       Start of time range or null for no limit
 * @param to         End of time range or null for no limit
 * @param maxRows    Maximum number of rows to retrieve or 0 for no limit
 * @param includeRawValues if true raw DCI values will be included into set
 * @return DCI data set
 * @throws IOException  if socket I/O error occurs
 * @throws NXCException if NetXMS server returns an error or operation was timed out
