DBX Agent Setting

Write the settings for the DBX agent in the whatap.conf file. For the options that can be set, see the following.

Default options

• license String

  To install the agent, set the project access key granted from the server. The project access key includes the agent's project and the encryption key for secured communication.

• whatap.server.host String

  Default 127.0.0.1,127.0.0.1

  Specify the IP address of the collection server to transfer the data collected by the agent. If there are multiple IP addresses for collection server redundancy, use comma (,) as the delimiter. The collection server proxy daemon must be serviced in the listening state for the set IP address.

• whatap.server.port String

  Default 6600

  Set the port of the collection server. Because only one port can be set, use the same port set in the "whatap_server_host" option.

• dbms String

  altibase

  Caution

  If other option values are entered, data collection for monitoring may not work.

• db_ip String

  Set the IP address of the database server to be monitored.

• db_port String

  Set the port used for DB communication.

Collecting data

• db_param_enabled Boolean

  Default true

  It sets whether or not to collect the DB parameters.

• conn_fail_count Int

  Default 15

  It sends a notification when the connection error occurs consecutively 15 times. You can adjust the notification trigger criteria by entering the desired number.

• long_run_session_sec Second

  Default 10 (unit: second)

  A session that has been running longer than the set time is treated as a long run session.

• skip_whatap_session Int

  Default 0

  If you set 1, the session in which the query to collect from WhaTap operates, does not appear in the active session list. (Default value: 0)

• tablespace_lock Boolean

  Default false

  To monitor tablespace locks that occur when adding data files or changing tablespaces, change the option value to true.

• xview_min_sec Int

  Default 0

  When collecting xview, collection is performed only when the query execution time is longer than the set time. The default setting is to collect all queries whose execution time is longer than 0 seconds.

Applying the AES 256 encryption

The WhaTap DBX agent transfers the collected data to the server after encryption. You can change this depending on the importance of the data or setting. Basically, the XOR operation and encryption through the AES algorithm are used, and encryption and decryption are performed by dividing the plain text into 128-bit units. It can be expanded up to 256 bits depending on the setting.

Add the following options to the whatap.conf file in the path where the WhaTap DBX agent has been installed.

whatap.conf

cypher_level=256

Add the settings and then restart the agent.

Agent name setting

Automatic configuration

If you do not set the agent name in the agent configuration (whatap.conf), the agent name is automatically determined by combining the IP address and the port number. For example, if the IP address is 10.11.12.13 and the port number is 3000, the agent name is set to DBX-12-13-3000.

The key variables that determine the agent name are as follows:

Configuration	Description
{type}	The DBX value is used.
{ip0}	The first byte of the IPv4 address is used. (e.g. 10 in 10.11.12.13)
{ip1}	The second byte of the IPv4 address is used. (e.g. 11 in 10.11.12.13)
{ip2}	The third byte of the IPv4 address is used. (e.g. 12 in 10.11.12.13)
{ip3}	The fourth byte of the IPv4 address is used. (e.g. 13 in 10.11.12.13)
{port}	Database server port

Note

If the IP address is not numeric like RDS, the name is set in the following format: DBX-{ip0}-{hash}-{port}, where the {hash} value is the IP address that has been converted to 4-digit hexadecimal number.

Manual configuration

To set the agent name manually, enter a desired name for the whatap.name or object_name option in the whatap.conf file. The entered name is assigned to the agent name.

whatap.conf

whatap.name=agent-1234
# or
object_name=agent-1234
