Trace Route Investigation

A Trace Route investigation records the path and each hop between the management console and end points to detect latency and routing issues.

When scheduling this investigation, the time zone you specify for the notification is also used to schedule the investigation.

Specify the following settings to launch or schedule a Trace Route investigation:

Target of Investigation

Specifies the target you want to investigate, such as a server, based on its target type. To investigate a group of targets, choose Server Aggregation from the Target Type list.

Investigation Options

Specifies the following options:

Investigate from

Specifies the monitoring device from which you want to launch the investigation. Choose a monitoring device that can communicate with the server or device you want to investigate.

Protocol

Specifies the protocol, either ICMP or TCP, to use for the Trace Route investigation. The only time the traceroute performance between ICMP and a given TCP port should vary is if QoS is actively giving priority of one over the other. In this case, TCP (if it is also marked by a network router as would be the true application traffic) might be a preferred method. ICMP is commonly used and accepted provided it is allowed to pass within a given architecture as sometimes it is blocked for security reasons.

Packet Size

Specifies the size of the packet, 32 to 8192 bytes, to investigate.

Retries

Specifies the number of tries, from 1 to 4, to get a response.

Route Searches

Specifies the number of attempts, from zero to 20, to find additional routes for the selected target.

Timeout (seconds)

Specifies the number of seconds, from 1 to 10, that must elapse to consider a server timed out.

Investigate Routers via SNMP

Specifies whether to perform an SNMP query on each network device for its performance details. For information about adding a network device to the management console, see the Administrator Guide.

Notification Options

Notifies the specified email recipients about the results of the investigation. Note that the investigation is scheduled using the specified time zone for the email notification.

Schedule

The scheduling options only appear if you chose to schedule the investigation. Schedule the investigation to run at a particular time on a particular date or schedule the investigation on a weekly or monthly basis.
