General Configure the system nickname, TDPID, login names, passwords
(hidden), and account strings (optional). Test the connection to Teradata
Database, and add or delete login names.
Canary Queries Configure canary queries used to test Teradata Database system response times. The SYSTEM HEARTBEAT canary query cannot be removed.
System Health Enable metrics for the SYSTEM HEALTH portlet. Configure degraded and critical thresholds for each metric.
Alerts Add, delete, copy, and configure alerts, or migrate existing Terdata
Manager alerts.
Data Collectors Enable, disable, and configure data collectors to capture and retain portlet, disk usage, and resource data.
Monitor Rates Set Teradata Database internal sample rates for sessions, node logging, and vproc logging.
You can view the amount of disk space used:
Disk usage View the percentage of total disk space being consumed by collected data on the managed server.
Twelve hour change
View the percentage of disk space used or has become available over the past twelve hours. Positive indicates the amount of space used has increased. Negative indicates the amount of space used has decreased.
Adding a Teradata Database System
This task describes how to add a Teradata Database System to Teradata Viewpoint. The system must be added before you can configure the data collectors to monitor the database.

CHARACTER
SET Fields
Session
Standard Character Set Configurations
When you configure a Teradata Database system, the CHARACTER SET section of the
GENERAL setup allows you define the charset that the system uses to communicate with
Teradata Viewpoint. The character set definitions are optional. If you do not define them,
Teradata Viewpoint uses the Teradata Database system settings.
Character Set Definition Suggestions
Monitor
JDBC Flag
The UTF8 session character set is strongly recommended for the Teradata Viewpoint session to ensure end-to-end fidelity of character data by avoiding conversion between character sets. However, the UTF8 session character set does not support the KANJI1 server character sets, which are used for storing data dictionary data in Teradata V2R6.x Japanese systems. For these systems, Japanese users must specify the
Kanji session character set.
The UNICODE session character set is not currently supported for the Teradata Performance Monitor and Console Partition. To create Teradata Viewpoint object names that connect Monitor and Console
Partitions, use Non-Unicode session character sets such as LATIN1252_0A, KANJISJIS_OS, and
KANJIEUC_OU.
To set the JDBC Flag, you must set the session character set and the monitor character set to ASCII. The
JDBC Flag setting is a legacy-support feature to assist the transition away from the unsupported use of the Teradata Database to store non-Latin characters in a Latin column, and the unsupported access of non-ASCII in an ASCII session character set. The JDBC Flag option specifies the CLIENT_CHARSET connection parameter, which can be used to override the Teradata JDBC Driver fixed-mapping of the
Teradata session character set to the Java character set. The valid values are the actual Java character set names. Here are two examples of valid JDBC Flag settings:
• Windows-936 from Chinese (PRC)
• Windows-950 for Chinese (Taiwan)

Data Collector Rates
Teradata Viewpoint uses a sample rate to collect data from the Teradata Database system and uses a default retention rate to keep the collected data for a time period or up to a certain size. The sample rate and retention rate vary for each data collector and can be adjusted as needed.
Alert Request has no retention rate because this data collector does not store data.

About Alerts
Alerts monitor the performance on a Teradata Database system and automatically take action when events occur. You can add, copy, and configure alerts, as well as migrate
Teradata Manager alerts.
You can activate alert actions that send a notification, or take some other type of action, when a metric exceeds a threshold.
After you add alert action sets in the ALERT SETUP portlet, they appear in the
TERADATA SYSTEMS portlet.
The types of alert actions you can choose are:
Send an Email Choose a defined email address and text message. Event information, such as date, time, event name, threshold, and actual value, is automatically added to the body of the email message.
Run a Program Choose a program to execute (.exe).
Run a BTEQ Script Choose a BTEQ script.
Notify SNMP System Choose an SNMP trap.
You can also choose alert actions for sessions including:
<Abort

Monitor Rates
After a Teradata System has been configured in Viewpoint, you can set Teradata Database internal sample rates for sessions, node/vproc, node logging, and vproc logging. These rates determine how often PM/API data are refreshed. The sample rates for node/vproc, node logging, and vproc logging must be an integer divisor of 3600.
