Enabling ssl in tomcat JSSE / APR

2014-10-15 Thread Shashank
Hi all

I was trying to enable ssl in my tomcat server. I dont know whether my 
tomcat is using JSSE or APR. but as I created a keystore and imported a 
cert into it , can I use JSSE type irrespective of the connector?

My server.xml block 




Thanks

Re: Authentication without Authorization ( JNDI Realm )

2009-12-04 Thread Shashank Rachamalla
Hi

The following is the Realm configuration being used:

ldap://ldapprime.pesgrid.wipro.com:389";
userBase="dc=wipro,dc=com" 
userSubtree="true"  
userSearch="(mail={0})"
roleBase="dc=wipro,dc=com"
roleSubtree="true"
roleName="objectClass"
roleSearch="(mail={0})"/>

The following is the security constraint specified in web.xml



/*


*




BASIC



inetOrgPerson



The following is an entry added to LDAP for testing:

dn: uid=ccpadmin, dc=wipro,dc=com
mail: ccpad...@wipro.com
uid: ccpadmin
userPassword:: YWRtaW4xMjM=
objectClass: inetOrgPerson
givenName: Cloud
sn: Administrator
cid: cloud
cn: Cloud Administrator


I am able to authenticate but authorization seems to fail ( error 403
forbidden )

Regards
Shashank

Hi

had to use roleSearch="(mail={1})" instead of roleSearch="(mail={0})"

{0} takes the user dn where as {1} takes the username.

Automatic scaling decisions based on performance metrics

2010-02-08 Thread Shashank Rachamalla
Hi

I am currently involved in developing a module which performs automatic
scaling of application server instances based on their performance. I am
using JMX to pull data pertaining to server and underlying jvm on which
the applications are deployed. I can also collect performance data for
guest operating system.  We are using mod_jk as load balancer. The
challenging task here is to decide when to scale out and when to scale
in. Please suggest some strategies used to determine the load at a
cluster level based on which scaling decisions can be taken. Also can
any scaling decisions be taken by considering performance statistics of
a single instance in a cluster.

The following are parameters currently monitored for each server
instance.

Guest OS

1) CPU Usage
2) Swap Usage

JVM 

1) JVM Free Memory

App Server ( context is / )

1) Maximum Request Processing Time.
2) Number of errors processing requests.
3) Number of errors encountered while processing requests.

Regards,
Shashank

Not able to get threadcount and thread busy metrices in Tocat 7.0

2012-02-10 Thread Mendiratta, Shashank
Hi , 
I am facing a problem. We used to monitor tomcat JVM and used to monitor " 
current ThreadCount " and "current Threadbusy" 
Recently we upgraded from tomcat 6.0 to tomcat 7.0.16 and we are not able to 
get these metrices . 
On digging in we found that in tomcat6.0 the thread pool metrices were 
retrieved by class "org.apache.tomcat.util.threads.ThreadPool "
But in tomcat 7.0 there is no such class instead it is replace by 
org.apache.tomcat.util.threads.ThreadPoolExecutor which does not give the above 
parameters. 
So my question is tomcat 7.0 how can we get the above metrices 

P.S- > Am new to tomcat so please bear if it is a silly question

In my experience, the PID can still exist of tomcat but a Java heap
crash has stopped it responding.

Checking a PID will not check if the application is responding.

You're better to do some sort of end to end monitoring

HI Darryl ,

Thanx , about that here the outbound port 80 is blocked so we cannot
wget , moreover this wont solve the problem as to why the the services
are getting hung. 

Well I had an idea, please critic it. Why not monitor the server.log
file if we get some kind of error. We send an alert and then restart the
service . Befire that we have to make a repository of types of error
that can occur 

Please do comment

It depends on the application you are running, but a simple test would
be to access the webpage (ensuring part of it is served from Tomcat, not
apache) and check for an expected response.

For example, a simple jsp page that prints out "ok"
You can then do a wget, and check for that string.

Cheers.

RE: How ot monitor hung tomcat/apache processes?

2010-09-22 Thread Mendiratta, Shashank
I get you point . well we are using dynatrace to keep a track on how
slow the server is serving pages and for the entire system metrics
monitoring we are using monit and both are done externally .  The
firewall has closed all the outbound ports so wget is not possible.

Its just that we have to monitor the JVM so that it does not hang but
yes you are right with dynatrace just has a monitoring window and it
does not restart the service. So I have to come up with a cript also
which how the system is serving pages if its to slow . then to restart
the JVM .

Are you trying to monitor from the same computer that tomcat is running
on? That's not a good idea. What happens if the entire system
crashes...you won't get any data/alerts. End to end uses another machine
to monitor the first.
You could monitor catalina.out for errors, but I don't think you'll
capture every possibility.
What would happen if the system stops serving pages (or serves them
slow)? That won't show in the logs.

What port is your application running on? You can use (from another
machine) wget {servername}:8080.

Yes This is the same problem I am facing. Sorry  I am kind of new to it
but can you tell me what kind of end to end monitoring should I do ?

In my experience, the PID can still exist of tomcat but a Java heap
crash has stopped it responding.

Checking a PID will not check if the application is responding.

You're better to do some sort of end to end monitoring

Hi ,

I am working on a monitoring system to find out hung tomcat/apache
processes .

By this I mean if the PID exists and still the apache / tomcat is not
responding that due to memory leak or variety of other reasons . Is
their a tool to find this .

Really?  That sounds, well, a little drastic...

Regd: Logging issue in apache tomcat 7.0.42

2013-11-12 Thread Shashank Gvs
Hi,

I wanted to have logging in tomcat, but currently using
juli/java.util.logging i am having a file with date in it (for example
catalina.11.12.2013.log) , i am unable to remove date as my additional
requirement is that i have to include daily rollover of the file.

Alternatively i have tried this using log4j by following the documentation.
I was able to get the log working properly if i start my tomcat using
startup,sh. But i am starting tomcat from an ant script in the following
way which is not at all forming the log. Can i be helped on this.

 









 
 

















Any help is appreciated.

Thanks & Regards,
Shashank
