394 CHAPTER 9: PERFORMANCE REPORTING
Figure 197 Daily Graph of HTTP Response Time
In this example over the course of two days, demand on your Web server
is spiky, but most of the time it is within acceptable levels. You feel that at
its current levels, performance is acceptable, but any increase in traffic
would necessitate an upgrade.
To get an indication of whether the demand is likely to increase based on
past performance, scroll further down the report to the yearly graph of
HTTP response time.
Figure 198 Yearly Graph of HTTP Response Time
From this you can see that the demand on your Web server has been
steady over the past two years, and thus you may conclude the Web
server does not require upgrading at this point in time.
