Configuring the ICMP service for monitoring

Foglight Net Monitor uses the ICMP (Internet Control Message Protocol) service to communicate with network devices. There are two versions of this service that are available for use:

Foglight Agent Manager ICMP service uses the udp2icmp application, that is installed with the Agent Manager, and can be used to issue ICMP messages to target devices.
OS-specific ICMP services use the following OS-level commands to issue ICMP messages to target devices:
tracert (Microsoft Windows only) or traceroute (Linux only)

Both types of ICMP services are started through an executable application and require proper permissions to execute. For more information, see Configuring the Agent Manager ICMP service and Configuring OS-Level ICMP services.

By default, Foglight Net Monitor uses the Agent Manager ICMP service for monitoring. OS-level ICMP services can be configured, if needed, using the following option

There are two ways to specify this option:

As a JVM system property, in the <fglam_home>/state/default/config/baseline.jvmargs.config file. For example:

Other options are available. For more information, see ICMP service command-line options.

The following table describes the Foglight Net Monitor parameters that can be used to configure the ICMP service. You can specify these options on the command line, or in an Agent Manager configuration file. For more information, see Configuring the Agent Manager ICMP service.

All agent instances managed by this Agent Manager uses the OS-level ICMP service. This type of ICMP service uses ping and traceroute/tracert commands. The login user must have proper permissions to execute these commands, without providing a password.

Unix/Linux only. If the login user does not have the permissions to execute the ping command, use this option to specify the command path.

Unix/Linux only. If the login user does not have the permissions to execute the traceroute command, use this option to specify the command path.

Unix/Linux only. Sets the thread pool size. You should specify at least 10.

Configuring the Agent Manager ICMP service

Configuring OS-Level ICMP services

Ensure that the ping and tracert commands are available.
Ensure that the ping and traceroute commands are available.
For Suse Linux with the apparmor module, enable traceroute to execute with the -I option. For example:

Managing monitored network devices

The Devices Management dashboard displays a list of the monitored network devices. It allows you to add or remove network devices from the collection, and to edit their data collection parameters.

You can add one or more network devices using the Devices Management dashboard, and select desired agents (monitoring locations). Use this dashboard to gain an understanding of the complexity of your monitored environment and to review any alarms associated with the monitored devices.

For complete details about the views appearing on this dashboard, see Net Monitor Devices Management views.
