Here is Sudama looking into the area of Server Performance Monitoring.
Do you keep a check on your Server Performance Parameters : App Server Monitoring?
What is Server Configuration? Is there any way to know your Configuration in depth!
Does your Organisation employ some technique so that
1. You bring all Server info at one place
2. You have a tabbed view of the Configuration details.
3. All your users can view and search all server config details and make right decisions based on the server status without any delay.
4. You can get quick details on Server, Machine, Ports, Cluster Config, Web applications, EJB apps, Connection Pools, JMS queues, JMS topics
What is the meaning of Server Config and what are the important parameters your Admin should know?
Know the type and version of the installed server, supported Java platform and its version, server directory, and other directories associated with the servers. It also displays start date of the server
Get the Remote machine details where your server is running. Retrieves info about OS of the machine, available processor count in the machine, host name and host address of the machine
Monitor the available services in a server and the port numbers associated with each service. Ports serve as communication endpoints. Each port is associated with a unique IP address of the host, as well as the type of protocol used for communication.
Provides necessary information on cluster configuration and it Helps the user to check if a server is participating in the cluster or not.
Provides information on web applications running currently. It helps the user to see available web applications in a particular server.
The EJB Applications tab displays available EJB (Enterprise JavaBean) applications in a particular server.
The connection pool acts as a reservoir for database connections. They are stored to be reused when future requests to the database are required. The Connection Pool tab displays the list of connection pools available in the server and its status.
The JMS (Java Message Service) Queue is a pipeline that contains messages that have been sent and are waiting to be read. JMS Queues tab displays available JMS queues in a particular server.
The JMS (Java Message Service) Topic is a distribution mechanism for publishing messages that are delivered to multiple subscribes. JMS Topics displays available JMS topics in a particular server.
Can your application get the Thread Dumps the Easier way!
By the way what the heck is Thread Dump ? You should have a simplified method for taking Thread Dumps.
Imagine this situation.
Ever caught up in a situation where the usual means for generating a thread dump does not work, making it difficult to track down irritating deadlock issues.
What to do to get out of the Deadlock ?
Does your application helps you by making Thread Dumps available in a centralized console.
Ask yourselves these questions
a) Does your application provides “Thread Dumps” feature
b) Does it make it easier to take Thread Dumps, bringing the Thread Dump at your disposal without hassle.
c) Does it enables you to save and maintain Thread Dumps for future reference
Get to the Root Cause: Thread Dumps helps user analyze Server Hang Situations and the Root Cause of it.
Why we need a Thread Dump?
When the application server freezes or hangs or becomes sluggish for no apparent reason, Thread dumps will reveal the exact state of your App server.
Server Performance and JNDI Tree Utility!
Your Ideal Server Performance Application shall empower you with details. JNDI feature strengthens the administrators to confirm the deployment (EJB) status, validate JDBC data source, JMS queries, JMS Topics and JMS connection factories.
JNDI provides a common interface to existing naming services, such as LDAP (Lightweight Directory Access Protocol) and DNS (Domain Name System).
Finding resources is of particular importance in medium to large-scale enterprise environments, where one application built may depend on services provided by applications written by other groups.
A well-designed naming infrastructure makes such projects possible by locating resources.
JNDI allows the components in distributed applications to locate each other.
Clients use the naming service to locate objects by name.
Is viewing the JNDI tree in the servers associated with it possible?
Do you get convenient JNDI view as part of your application’s admin console.?
