Tomcat6 Manager App HOW-TO
I would appreciate some clarifications/advice on this How-To..
It appears that the instruction to add (paths corrected)
<Context path="/manager" privileged="true"
docBase="/usr/local/tomcat/webapps/manager">
</Context>
is wrong (based on message from Charles Caldarale on 5/16/2007)
So.. in reading the rest of the instructions I'm finding things are not
quite working as documented.
Searched this list and google and so far have not come up with any answers:
Specifically..
1) Is the instruction that you add a manager.xml to each
$CATALINA_HOME/conf/[enginename]/[hostname]
..folder required? (I assume the path should be corrected since there
is no longer any "server" directory structure.)
.. at this point it does not seem to matter.. but I would like access to
virtual hosts..
2) So I can access the localhost manager at:
http://localhost:8080/manager/html
but can not access the host-manager at:
http://localhost:8080/host-manager/html
..I get a 403 (I did try adding a host-manager role to the
tomcat-user.xml , but no joy)
Is there something that has not been documented as yet to configure
this..???
3) I can not access a virtual host Manager at
http://www.domainhere.com:8080/manager/html
Thank you for any hints or advice..
John..

What are you using to monitor the performance of Tomcat?
Posted by Simon Kok <Si...@rewardstream.com>.
Hi there.
We're currently looking at a third-party product from Adventnet called Application Manager to monitor our Tomcat 5.x servers.
Are there other third-party solutions out there that can provide performance and usage statistics? We would like to monitor the performance if the servlets at a url level.

Ah yes, thanks, that makes sense now...
I think for production I'm going to need to fall back to 5.5.23 for now,
too many issues to resolve and test. I'll setup a test machine for
Tomcat6 and keep working on it..
I appreciate your assistance..

Not required, but it's an alternative to creating manager.xml files
under each conf/Catalina/[host] directory that all have a docBase
attribute pointing to the single copy of the webapp.

I guess I understood from an earlier post from you that it was a rather
"strong" no-no.. Which made it's presence in the HOW-TO rather odd..
I also gather that you should copy the manager directory into each
webapp..???
Thank you for clarifying these issues..

This is now clarified for TC4, 5 & 6.

The only part that I find somewhat misleading is the following:
"There are two ways to configure the Manager web application Context:
" * Install the manager.xml context configuration file in the
" $CATALINA_HOME/conf/[enginename]/[hostname] folder.
" * Configure the Manager Context within the Host configuration
" in your Tomcat server.xml configuration. Here is an example:
" <Context path="/manager" privileged="true"
"
docBase="/usr/local/kinetic/tomcat6/server/webapps/manager">
" </Context>"
The first bullet is really only needed when additional <Host> elements
have been configured, and you want a manager webapp for each. It fails
to mention that the manager webapp is automatically set up for the
default <Host> in the standard Tomcat 6 download.
The second bullet should probably be eliminated, since it's no longer in
keeping with the philosophy of avoiding placing webapp configurations
inside the server.xml file. It may be there simply for completeness,
but ideally it should at least include a caveat.

You are basically saying, as I understand it, that it is either wrong
or incomplete.
(It may, of course, just be that my ignorance is so bad that I can make
sense of it all..<G>)

Great thanks.. That is the missing piece(s) in the docs... Ditto for

The path attribute is only valid when the <Context> element is in
server.xml, which is strongly discouraged. For other <Context> uses,
the path is derived from the name of war file (or directory) or the name
of the .xml file in conf/Catalina/[host].

Please point out where in the Tomcat 6 doc you're finding discrepancies.

Not for Tomcat 6, since the directory structure has changed. In TC 5.5
and older, the various management applications were located outside of
the normal <Host> appBase (in server/webapps), and therefore required
[appname].xml files in conf/Catalina/[host]. For TC 6, the management
applications are located under the configured appBase directory, so
their <Context> elements can be found in their respective META-INF
directories.
If you configure multiple <Host> elements with differing appBase
attributes, you have two choices. Either copy the management
applications to each appBase, or keep them in one spot and create
[appname].xml files with appropriate docBase attributes in each
conf/[engine]/[host], similar to TC 5.5.

Look in the WEB-INF/web.xml file for host-manager; you'll see that the
required role name is admin, not manager or host-manager.

What appBase did you configure for the www.domainhere.com <Host>? If
you don't have a manager webapp deployed there, you'll need to create a
conf/Catalina/www.domainhere.com/manager.xml file that contains a
<Context> element with a docBase attribute that points to the location
of the manager webapp.
