6 Configuration management
APM provides the following additional configuration management functions:
• Threshold Management —Sets threshold alarm conditions for the monitoring application indexes. If
the collected indexes meet the threshold alarm conditions, APM sends a corresponding alarm
through the alarm function of the IMC platform. If the alarm notification and forwarding
configuration is set correctly, operators can receive alarm information sent by APM through emails
or short messages.
• Baseline Configuration—Enables or disables the baseline function for application indexes. When
you enable the baseline function for an application index, APM performs the following operations:
{
Collects the index data.
{
Generates initial baseline data after seven days.
{
Generates stable baseline data after five weeks.
APM determines the index state according to the baseline data. Alarms are generated when the
baseline data is in abnormal state. If the alarm notification and forwarding configuration is set
correctly, operators can receive alarm information sent by APM through emails or short messages.
• Port Configuration —Sets default application monitor and traffic collection ports for applications.
Through ports, APM can identify different applications in Auto Discovery and traffic collection.
• Probe Configuration —Manages a list of probes. A probe is a server where the probe application
is installed. Operators can collect the network traffic of applications by mirroring network traffic to
the probe.
• Parameter Configuration —Sets APM system parameters, including the monitor data retention
periods and data background colors.
• Template Configuration—Provides application templates for application monitors and agent
templates for remotely installed agents. Using templates simplifies the configuration and reduces
the chances of making mistakes.
Threshold management
APM predefines multiple monitor indexes for each type of applications, and sets the threshold alarm
conditions for certain key monitor indexes. Operators can view application monitor indexes configured
with the threshold alarm function and their threshold configurations. To enable the threshold alarm
function for other application monitor indexes, use the monitor index adding function in threshold
configuration.
Application monitor thresholds can be global or custom, depending on the effective range. You can set
a global threshold for a monitor index only in threshold configuration. You can set a custom threshold in
the application monitor report or custom view report. By default, monitor indexes enabled with the
threshold alarm function use global thresholds.
• Global threshold—Applies to a specific widely-deployed application type. The same application
type has the same global threshold.
• Custom threshold—Used to monitor a single application. With custom thresholds, applications of
the same type can use different thresholds.
