### Web Container Statistics

The web container fits into the tree of objects as shown in The Applications Tree. Web container statistics are displayed for each individual web application. Statistics available for the web container for Servlets are shown in Web Container Statistics and statistics available for web modules are shown in Web Container Statistics.

Table 16–7 Web Container (Servlet) Statistics

Statistic | Units | Data Type | Comments
--- | --- | --- | ---
`errorcount` | Number | CountStatistic | Cumulative number of cases where the response code is greater than or equal to 400.
`maxtime` | Milliseconds | CountStatistic | The maximum amount of time the web container waits for requests.
`processingtime` | Milliseconds | CountStatistic | Cumulative value of the amount of time required to process each request. The processing time is the average of request processing times divided by the request count.
`requestcount` | Number | CountStatistic | The total number of requests processed so far.

Statistics available for web modules are shown in Web Container Statistics.
