Ping Response Time vs Packet Size Investigation

A Ping Response vs. Packet Size investigation measures the time it takes to receive a ping reply for TCP ping requests (data packets) of various sizes. Helps track excessive delays and lack of connectivity at various packet sizes.

A Ping Response Time vs. Packet Size Investigation produces a report about the minimum, maximum, and average packet round trip time. Unlike the other types of investigations, the management console does not automatically launch this investigation in response to an incident.

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 Ping Response vs. Packet Size 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.

Largest Packet Size

Select from 512 to 8192 bytes for the size of the largest packet to investigate.

Sampling Type

Specifies an option for checking packet size:

  • Linear. Checks each packet size up to the largest packet size specified. This option requires more samples.
  • Doubling. Covers the range with fewer samples and with less coverage of packet sizes.
Samples at each Size

Select from 1 to 10 for the number of samples at each size.

Timeout (seconds)

Select 1 to 10 for the number of seconds that must elapse for a server to be considered timed out.

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.
