SaaS Network Connectivity Test

If your Office 365 users complain that they are unable to access the cloud services, you may want to check the quality of the network link to the Office 365 portal. A flaky or latent network connection can sometimes deny users access to their critical Office 365 services, adversely impacting their overall cloud experience. To avoid this, periodically run the SaaS Network Connectivity test, and check the health of the network connection to the Office 365 portal.

This is an external test that emulates a network-level ping to the portal and reports whether/not network connectivity to the portal is available, and if so, how responsive the portal is to network requests. In the process, the test reveals any break or slowness in network connection to the portal.

Target of the test : Office 365

Agent deploying the test : An external agent

Outputs of the test : One set of results for the Office 365 portal being monitored

Configurable parameters for the test

Parameters Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured. By default, this is portal.office.com

Packet Size

The size of packets used for the test (in bytes)

Packet Count

The number of packets to be transmitted during the test

Timeout

How long after transmission should a packet be deemed lost (in seconds)

Packet Interval

Represents the interval (in milliseconds) between successive packet transmissions during the execution of the network test for a specific target.

Targets

By default, this is set to portal.office.com. This test will emulate a network-level ping to this target only.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time the test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD Frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enabled/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Avg network delay

Indicates the average delay between transmission of packet to the portal and receipt of the response to the packet at the source.

Seconds

An increase in network latency could result from misconfiguration of the router(s) along the path, network congestion, retransmissions at the network, etc.

Min network delay

The minimum time between transmission of a packet and receipt of the response back from the portal.

Seconds

A significant increase in the minimum round-trip time is often a sure sign of network congestion.

Packet loss

Indicates the percentage of packets lost during transmission from source to portal and back.

Percent

Packet loss is often caused by network buffer overflows at a network router or by packet corruptions over the network. The detailed diagnosis for this measure provides a listing of routers that are on the path from the external agent to target portal, and the delays on each hop. This information can be used to diagnose the hop(s) that could be causing excessive packet loss/delays.

Network availability

Indicates whether the network connection to the portal is available or not

Percent

A value of 100 indicates that the portal is connected over the network. The value 0 indicates that the portal is not connected.

Typically, the value 100 corresponds to a Packet loss of 0.
