Subject tomcat "manager" servlet stats sometimes off by one?
Date Mon, 27 Dec 2004 20:25:05 GMT
hi,

regarding http://<host>:8080/manager/status/all

i am only using connector http8080. i was wondering if
"Request count" and "Error count" for http8080 should
be the sum of "Request count" and "Error count" of all
web applications using port 8080?

for example, in the below, http8080 shows 15 requests.
but the sum of all web application requests is 16:

http8080:
Max processing time: 3765 ms Processing time: 7 s
Request count: 15 Error count: 5 Bytes received: 0.00
MB Bytes sent: 0.44 MB

web applications:
Processing time: 2 s Max time: 2293 ms Request count:
1 Error count: 0 Load time: 463 ms Classloading time:
454 ms
Processing time: 0 s Max time: 44 ms Request count: 6
Error count: 0 Load time: 1 ms Classloading time: 0 ms
Processing time: 4 s Max time: 3473 ms Request count:
4 Error count: 0 Load time: 35 ms Classloading time:
32 ms
Processing time: 0 s Max time: 7 ms Request count: 5
Error count: 5 Load time: 42 ms Classloading time: 41
ms

i've also see the case where error count is off by
one. for example, http8080 shows 4 errors, but the sum
of all web application errors is 3.

http8080:
Max processing time: 1178 ms Processing time: 2 s
Request count: 9 Error count: 4 Bytes received: 0.00
MB Bytes sent: 0.03 MB

web applications:
Processing time: 0 s Max time: 306 ms Request count: 1
Error count: 0 Load time: 184 ms Classloading time: 5
ms
Processing time: 0 s Max time: 717 ms Request count: 1
Error count: 0 Load time: 625 ms Classloading time:
595 ms
Processing time: 0 s Max time: 12 ms Request count: 2
Error count: 0 Load time: 0 ms Classloading time: 0 ms
Processing time: 0 s Max time: 160 ms Request count: 2
Error count: 0 Load time: 119 ms Classloading time: 18
ms
Processing time: 0 s Max time: 14 ms Request count: 3
Error count: 3 Load time: 44 ms Classloading time: 43
ms

any ideas? not sure if this is a known issue or a
problem with my setup..

thanks!
