Application Traffic
APM collects SNMP service traffic based on the IP address and port number of the SNMP host. The
Application Traffic area layout is shown in Figure 40.
Figure 363 Application Traffic area layout
Application Traffic area fields:
Application Traffic trend graph—Shows changes of inbound and outbound traffic over the last 1
hour. The green curve shows the inbound traffic and the orange curve shows the outbound traffic.
To change the report period, click the Last 1 Hour icon on the upper right of the graph, and then

DNS service
Domain Name System (DNS) is a core Internet service. With DNS, users can use easy-to-remember
domain names to access websites. The DNS service can automatically translate the domain names you
specified into IP addresses. The default DNS service ports are TCP 53 and UDP 53.
APM monitors the DNS service status by requesting the DNS service to translate a specified domain
name into an IP address. This section describes how to add and modify a DNS monitor, and helps view
the monitor report.
Adding a DNS service application monitor
APM monitors DNS status through DNS service ports TCP/UDP 53. Before adding the application
monitor for DNS service, complete the following tasks:
Add the target host to the IMC Platform. For information about adding a host to the IMC Platform,
see HP IMC Base Platform Administrator Guide.
To view traffic statistics in the monitor report of the DNS application, make sure at least one probe
is configured in APM. After a DNS service application monitor is added, APM sends the IP address
of the monitored DNS application to the probes for traffic collection.
