status worker
Hello,
I am new to tomcat in general and I am trying to setup jk_mod (using 1.2.25) and I have already successfully installed it and put workers serving dynamic content from the tomcat server with load balancing.
Now I wanted to setup the status worker to get some statistics. I am using the default configuration for it but probably something basic is missing:
worker.properties file:
worker.list=lb1 , lb2 , jkstatus
[...]
jkstatus.host=rh02
jkstatus.port=10001
jkstatus.username=manager
jkstatus.password=tomcat
jkstatus.url=http://${jkstatus.host}:${jkstatus.port}/jkstatus
jkstatus.testlb=lb1
jkstatus.testworker=worker42
uriworkermap.properties file:
/jkmanager=jkstatus
Apache httpd.conf file:
JkWorkersFile /usr/local/apache2/conf/workers.properties
JkMountFile /usr/local/apache2/conf/uriworkermap.properties
Include /usr/local/apache2/conf/tomcat-55.conf
Include /usr/local/apache2/conf/tomcat-50.conf
Apache httpd is on host rh01 and Tomcat server is on host rh02. When I try to access http://rh01/jkmanager it just says it can't find the document... can someone say what am I missing? The documentation doesn't provide much troubleshoot :(
Regards,
Nuno

Thanks. I did not find the bug listed when I searched.

It's a known bug, which has beend discussed on the developers list only
very recently. See
http://marc.info/?t=120667098200003&r=1&w=2
Your workaround (using ant 1.5) seems fine. The final solution is still
pending, but it's quite possible, that Mark does a fix for the future
4.1.38. This still needs some clarification though.

Thank you.
It was related with the virtual hosts and it Works now.

Sure it has. It asks mod_jk and mod_jk knows all about worker statistics

Do you have any virtual hosts? If so, you need to put the JkMountFile
into the virtual host, which handles your /jkmanager request.
If it doesn't work at all, set JkLogLevel to debug, restart httpd and
send a single request for /jkmanager. After that, post the contents of
the JkLogFile.

Hi,
I tried before to do as you said and it did not work. I guess this is because when I make the request the one answering is Apache httpd and not Tomcat, and I don't think httpd has any clue of what a status worker is.
I tried to simplify it with just these 3 lines:
worker.jkstatus.type=status
worker.jkstatus.host=rh02
worker.jkstatus.port=10002
So that it knows where to find Tomcat but still the same problem as with the other 2 previous configurations:
The requested URL /jkmanager was not found on this server.

Correct your workers.properties
Remove all of the above lines of the form
jkstatus.attribute=value
because none of the attributes you are using makes much sense.
Add:
worker.jkstatus.type=status
to let mod_jk know, when it tries to send a request to the worker with
name jkstatus, that there is not host/port/Tomcat behind it, but instead
it should generate its own status page.
If it works, then you should add an authentication/authorization
mechanism inside httpd to the URL /jkmanager (e.g. a Location directive
and inside a required user/password; this can be done with usual httpd
procedures, nothing mod_jk specific).

Rainer

Remove all of the above lines of the form
jkstatus.attribute=value
because none of the attributes you are using makes much sense.
Add:
worker.jkstatus.type=status
to let mod_jk know, when it tries to send a request to the worker with
name jkstatus, that there is not host/port/Tomcat behind it, but instead
it should generate its own status page.
If it works, then you should add an authentication/authorization
mechanism inside httpd to the URL /jkmanager (e.g. a Location directive
and inside a required user/password; this can be done with usual httpd
procedures, nothing mod_jk specific).
