Agent name identification
WhaTap basically uses the data collected from application servers to identify each server while collecting monitoring data. Basic information uses the application server as a unique identifier by a combination of application server's type, IP address, and such. If necessary, use the name set by the user or change the pattern to a unique value. The agent name must be unique.
The reason why the data extracted from the application server is used, is like the following. When a communication loss caused by the stop of the application server, network disconnection, or agent problem between the collection server and the agent, is restored, the continuity of the data from the reconnected agent is maintained.
Agent naming method
The default patterns used to identify the application server are as follows:
{type}-{ip2}-{ip3}-{process}
To change the default pattern value, modify whatap.conf as follows:
object_name={type}-{ip2}-{ip3}-{process}
- The agent name takes effect after the Whatap .NET service has been restarted.
Variable of the agent name
Variable | Description |
---|---|
{type} | Name of the application server |
{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) |
{process} | Process name of the application server |
{hostname} | Host name |
Setting the agent name
- The agent name takes effect after the Whatap .NET service has been restarted.
-
object_name String
Default
{type}-{ip2}-{ip3}-{process}
It is an agent naming (ONAME) scheme to identify applications. An OID is created based on the ONAME.
-
app_name String
It is a component used in the agent naming (ONAME) scheme to identify applications. It corresponds to the
{type}
among theobject_name
options. -
app_process_name String
It is a component used in the agent naming scheme to identify applications. It sets the target process to collect data of the application server such as CPU and heap memory by using application process names. The value corresponds to the
{process}
of theobject_name
.
-
whatap.okind String
You can configure monitoring units by grouping multiple agents into "type-based" groups. This option allows you to monitor and manage multiple agents in groups, analyze performance metrics, and set the alerts.
NoteYou can check it as a group option classified as By kind in the Dashboard and Analysis, Statistics menus.
-
whatap.onode String
You can configure monitoring units by grouping multiple agents into "node-based" groups. This option allows you to monitor and manage multiple agents in groups, analyze performance metrics, and set the alerts.
NoteYou can check it as a group option classified for nodes in the Dashboard and Analysis, Statistics menus.
