System ConfigurationSystem Configuration
The System Configuration panel parameters for the Reporting Engine manage service configuration for a Reporting Engine service. When you add a Reporting Engine service, default values are in effect. The default values are designed to accommodate most environments and recommends that you do not edit these values because it may adversely affect performance.
The following figure displays the fields that can be configured in the System Configuration panel:
The following table describes the System Configuration panel features.
| Name | Config Value |
|---|---|
| Allow Administrators Full Access |
Select the checkbox if you want to access all the Reporting Engine objects (Reports, Rule, Charts, Schedule, and List) created by other users (non-admin). By default, this is not enabled. Note: If you enable the checkbox and then disable it, the access on all Reporting Engine objects that were enabled by selecting the checkbox will not be accessible. But, if you have defined the access on specific objects via Permissions window (Reports > Manage > RE Object > |
| Allow Reporting Engine Content Administrators Full Access | Select the checkbox if you want to access all the Reporting Engine objects (Reports, Rule, Charts, Schedule, and List) created by other users. By default, this is enabled. If disabled, you cannot access the Reporting Engine objects (Reports, Rule, Charts, Schedule, and List) created by other users. |
| Common thread pool count |
The number of thread pools assigned for executing common tasks on the Reporting Engine. A valid value is an integer (20 default). |
| Enable Output Actions for Completed Reports |
Select the checkbox to process the output actions only for reports with all rule executions successful. By default, this is enabled. If disabled, the output actions are processed for all scenarios (completed, partial, failure). |
| Forward Alerts to Respond |
Select the checkbox to forward all the alerts to Respond. By default, this is not enabled. |
| Max# of Concurrent Alerts |
The maximum number of alerts that can be run simultaneously. This has a direct impact on the NetWitness service against which the alerts are run, as each alert consumes a query thread on the NetWitness service. A valid value is an integer (10 default). |
| Max # of Concurrent Charts |
The maximum number of charts that can be run simultaneously. A valid value is an integer (10 default). |
| Max # of Concurrent LookupAndAdd Queries |
The maximum number of parallel LookupAndAdd Queries that can be run per NWDB rule. A valid value is an integer (2 default). When you increase this value, for better performance, you must ensure the NWDB data source is configured to handle the parallel queries. |
| Max # Concurrent List Value Reports |
The maximum number of list value reports per schedule that can be generated in parallel. A valid value is an integer (1 default). |
| Max # List Value Reports |
The maximum number of list value reports generated, irrespective of the number of values in the list. A valid value is an integer (10000 default). |
| Max rows stored per Rule (Billions) |
The maximum number of rows that a rule can fetch when queried. A valid value is an integer (100 default). |
| Maximum disk space threshold |
The maximum disk space threshold allotted (in GB) to execute reports, alerts and charts. The initial value is configured based on the available system space. |
| Minimum disk space threshold |
The minimum disk space threshold allotted (in percentage) required to execute reports, charts, and alerts. By default, this is value is set to 5. Note: If the minimum threshold is reached, then the execution of reports, charts and alerts will stop even if the service is running. |
| NWDB Info Queries Time Out |
The info queries time out in seconds for NWDB server. A valid value is an integer (1800 default). |
| NWDB Maximum aggregate Rows |
The maximum number of rows that is returned when an aggregation is used in the NWDB rule. A valid value is an integer (1000 default). |
| NWDB Query Time out |
The time out in seconds for NWDB server to time out the rule execution, if it cannot process the result in configured time. A valid value is an integer (259200000 default). |
| Process output actions for successful reports only |
Select this checkbox to process output actions only for reports whose all rule executions are successful. When you de-select this checkbox, output action will be triggered for partial, completed, and failed reports. Note: This is applicable for all output actions except for dynamic list output actions. |
| Retain Alert history for # days |
The maximum number of days to retain the alert history and alert status. A valid value is an integer (100 default). |
| Retain Chart history for # days |
The maximum number of days to retain the chart history and chart status. A valid value is an integer (30 default). |
| Retain Report history for # days |
The maximum number of days the system retains report history and report status. A valid value is an integer (100 default). |
| Schedule Thread pool count |
The number of thread pools assigned for scheduled tasks (for example, clearing history) on the Reporting Engine. A valid value is an integer (5 default). |
Logging ConfigurationLogging Configuration
The Logging Configuration panel parameters of the Reporting Engine manages the logging configuration for a Reporting Engine service. When you add a Reporting Engine service, default values are in effect. NetWitness designed the default values to accommodate most environments and recommends that you do not edit these values because it may adversely affect performance of the Reporting Engine.
The following figure displays the fields that can be configured in the Logging Configuration panel.
The following table describes the Logging Configuration panel features.
| Name | Config Value |
|---|---|
| Log Level |
The logging level that determines the scope of information included in log files. Possible values are:
|
| Maximum # Backup Files |
The maximum number of backup log files the system retains. A valid value is an integer (9 default). |
| Max Log Size |
The maximum size (in bytes) of the primary log file. A valid value is an integer (4194304 default). |

Warehouse Kerberos ConfigurationWarehouse Kerberos Configuration
The Warehouse Kerberos Configuration panel provides a way to specify the Kerberos Keytab file on this Reporting Engine.
The following figure displays the field that can be configured in the Warehouse Kerberos Configuration panel:
The following table describes the Kerberos Configuration panel features:
| Name | Config Value |
|---|---|
| Kerberos Keytab File |
The Kerberos keytab file location. For example: /var/netwitness/re-server/rsa/soc/reporting-engine/conf/hive.keytab |
The default Kerberos configuration file is located at, /etc/kbr5.conf in the Reporting Engine. You can modify the configuration file to provide details for Kerberos realms and other parameters related to Kerberos.
Added the host name (or FQDN) and IP address of the Horton Works nodes and Warehouse Connector to the DNS server. If the DNS server is not configured, add the host name (or FQDN) and IP address of the Horton Works nodes and Warehouse Connector to the /etc/hosts file in the host on which the Warehouse Connector service is installed.
