Telnet response is received from Linux within the timeout time, APM considers that the
interaction has failed.
SNMP parameters
− Edit SNMP Parameters—Select this option if you want to manually configure SNMP
parameters for APM. Make sure the SNMP settings are the same as those on Linux.
− Select an Existing Template—Select this option if you want to select an existing SNMP
template for APM. For information about setting SNMP parameter templates, see H3C IMC
Base Platform Administrator Guide.
− Parameter Type—Select the SNMP parameter type. Options include SNMPv1, SNMPv2c,
and SNMPv3 Template. The SNMPv3 Template option is available only when Select an
Existing Template is selected.
− Read-Only Community String—Enter the SNMP read-only community string, with which
APM can read MIB variables from the Linux host.
− Read-Write Community String—Enter the read-write SNMP community string, with which
APM can read MIB variables from or write MIB variables to the Linux host.
− Timeout (1-60 seconds)—Enter the maximum time period that APM waits for an SNMP
response from Linux. The value range is 1 to 60 seconds and the default is 4 seconds. If no
SNMP response is received from Linux within the timeout time, APM considers that the
interaction has failed.
− Retries (1-20)—Enter how many times APM retries to send SNMP packets to the Linux host.
{
Contact—Enter the contact information, such as name, email address, and telephone number.
The default is the username of the operator who created the application monitor.
{
Related Applications—Add the application that Linux depends on. Enter the complete or part of
the application monitor name in the Search field at the top of the window, and click Search.
Select the applications that Linux depends on, and then click OK.
Operating system applications, such as Windows, AIX, SCO UNIX, FreeBSD, OpenBSD,
HP-UX, Solaris, Mac OS, and Linux, cannot be selected. Operators can view all dependencies
of the application in the dependency topology.
{
Detect Application—Select this parameter if you want to enable application detection.
Application detection enables APM to verify connection to the application by using the previous
parameter settings, and to determine whether to add the application monitor based on the
verification result. APM adds the application monitor only when it can connect to the
application. When this parameter is not selected, APM adds the application monitor without
verifying the connection.
5. Click OK.
Modifying a Linux application monitor
Authorized users can modify all parameters except the IP address of a Linux application monitor. When
the IP address of a monitored Linux host changes, operators must add a new application monitor for the
host. However, the new application monitor cannot inherit the history data from the previous application
monitor.
To modify a Linux application monitor:
1. Click the Resource tab.
2. Select Application Manager > Application Monitor from the navigation tree.
