Chapter 5 106 Sniffer Portable Professional The Rsp Time value specifies at what point a response using the specified protocol is considered “slow.” For example, if Rsp Time were set to 5000 milliseconds for HTTP, any response to an HTTP request that took longer than 5000 milliseconds would be considered “slow.” When the percentage of “slow” responses on a given Server-Client connection exceeds the % Applied threshold (see below), the Monitor generates an alarm on the connection. The % Applied value specifies the maximum acceptable percentage of responses exceeding the Rsp Time threshold on a given connection using the specified protocol. When the percentage of connections exceeding the Rsp Time threshold on a given Server-Client connection exceeds the % Applied threshold, the Monitor generates an alarm on the connection. Generated alarms are written to the alarm log. Actions take place as a result of generated alarms according to the options you have set on the Alarms tab of the Options dialog box. See Managing Alarms on page 257 for details. The following example shows the ART application window in the tabular view along with descriptions of its toolbar items.
