Measures reported by SaaSTcpCnctvtyTest
If your Microsoft Yammer users complain of inaccessibility, you may want to check the quality of the network link (TCP connection) to the Microsoft Yammer. A flaky or latent TCP network connection to the Microsoft Yammer can sometimes deny access to the users, thus, adversely impacting their overall experience with Microsoft Yammer. To avoid this, periodically run the SaaSTcpCnctvtyTest test, and check the health of the TCP connections to the Microsoft Yammer.
This is an external test that emulates a TCP connection to the Microsoft Yammer and reports the count of connections that were successful and the count of connections that failed. In addition, this test also throws light on how responsive the Microsoft Yammer is to TCP connection requests. In the process, the test reveals any break or slowness in the network connection to the Microsoft Yammer service.
Outputs of the test : One set of results for each SITE URL:Port monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| tcp_psent |
Indicates the number of TCP connections that were successful for this site. |
Number |
|
| tcp_plost |
Indicates the number of TCP connections that failed for this site. |
Number |
A high value for this measure indicates a flaky/latent network connection. |
| tcp_plost_p |
Indicates the percentage of connections that failed for this site. |
Percent |
Ideally, the value of this measure should be close to 0%. |
| tcp_tmax |
Indicates the maximum time taken by this site to respond to TCP connection requests that it receives. |
Milliseconds |
Latency being high denotes a problem. Poor latencies may be due to the site being overloaded or misconfigured. If the URL accessed involves the generation of dynamic content, backend problems (e.g., an overload at the application server or a database failure) can also result in an increase in latency. |
| tcp_tmin |
Indicates the minimum time taken by this site to respond to TCP connection requests that it receives. |
Milliseconds |
A significant increase in the minimum latency is often a sure sign of network congestion. |
| tcp_tavg |
Indicates the average time taken by this site to respond to TCP connection requests that it receives. |
Milliseconds |
