Tool for monitoring Tomcat from the client side
Hi.
I'm searching a tool similar to nagios wich allows me do "client-side
real testing" of my Tomcat webapps. Something that lets me do a HTTP
request say every minute and store the result (OK or FAILED) of each
request.
Nagios seems to be a good choice, but it requires C programming for the plugins.
Any alternatives for java (or groovy)?
Thanks.

you'd need APR or NIO to be able to sustain a large number of keep
alives. If you don't use keep alives, then it wont matter
Tomcat Native -> APR lib -> C is no difference than NIO -> VM -> C,
hence the performance shouldn't be very different.

Very interesting.
So if you have a typical large-app production environment with a
hardware ssl (for example by the load balancer) you don't need the
APR?
Hence another evidence that java's performance are equal or better than c?

thats correct, it will be included in 6.0, in terms of performance it
ranks like this
HTTP Nr Of Connections < maxThreads
1. Blocking IO Connector
2. Java NIO connector and APR connector are fairly similar
HTTP Nr Of Connections > maxThreads
1. Java NIO connector and APR connector are fairly similar
2. Blocking IO Connector
HTTPS
1. The APR connector due to built in with native OpenSSL
2. NIO connector
3. Blocking IO connector

I thought Filip coded something similar, a pooling NIO connector in java.

From http://tomcat.apache.org/tomcat-5.5-doc/apr.html
When APR is enabled, the HTTP connector will use sendfile for hadling
large static files (all such files will be sent ansychronously using
high performance kernel level calls), and will use a socket poller for
keepalive, increasing scalability of the server.
On Linux, epoll is used if available.

Good question, and I don't know the answer. It would be interesting to
see if there's any performance difference by recoding the pure Java
request handler in Tomcat to use NIO and its polling capability. Any
volunteers?

This slightly besser performance, is it achieved by C or by using epoll?

Not true - the Tomcat code is pure Java. You can optionally replace
some of the comm code with the Apache Portable Runtime (APR), which is
written in C. This provides slightly better performance.

Hello Andrew-
Just as a FYI-
The majority of the tomcat catalina engine is written in C and C++ for performance reasons
Thus far I have not seen the fast performance of C/C++ with perl or php or CF (without some sort of translator to native code)
Has anyone seen or heard benchmarks to prove this wrong?

Why do you need c?
Works with perl and shell scripts...
You could even use java if you wanted....

I would second the use of JMeter. I have used it pretty extensively and it
is reasonably good. I wish I could record using it as a proxy and play back
the recording. Anyone know if this is possible? How about with another
tool?

Tomcat monitoring
Posted by Ra...@stj.gov.br.
Hi;
I attended to an Oracle IAS event and they presented their Enterprise
Manager 10g, and they showed some great monitoring capabilities. Here I
quote some of them from their document
"http://www.oracle.com/technology/products/oem/pdf/wp_aslm_10g.pdf":
"The tracing functionality provides an on-demand tool that lets
administrators examine in detail all invocation paths of a transaction,
and isolate the exact tier and location of a problem. All invocation paths
of a transaction are traced and hierarchically broken down by servlet/JSP,
EJB, JDBC/SQL times. Further drill-downs into each component identify
response time breakouts by invocation path. Click-to-SQL drill-downs allow
administrators to navigate down from a transaction view and examine the
underlying SQL statements." (Page 6)
"URL processing time and load activity graphs provide administrators with
information on the impact of server activity on response times." (Page 7)
"Enterprise Manager provides correlation of CPU utilization, memory, and
I/O usage of all Web application components to help administrators
determine where resources are constrained." (Page 8)
Well, my question is if there is any way to do such (or any) monitoring
with Tomcat 5.5.17. If not, is there any monitoring tool that you guys use
to monitor and troubleshoot Tomcat? Maybe just tomcat/java commands that
shows status/monitoring info. Actually we only graph URL response times
and load keep an eye on the logs.
Any info is welcome.
Thanks a lot.
