Fusion Middleware Monitoring Metrics ( weblogic)

Today Iam gonna talk about Fusion Middleware Monitoring specifically on the weblogic which is the core component of the Oracle Fusion Middleware Stack.

First question which arises when we are building the middleware infrastructure is what to monitor which is the key component of the High Availability and Providing Reliable service to the customers by identifying the bottlenecks and effected areas using standard weblogic metrics.

In my view I would divide them into 10 subcategories 

1.  Availability/Capacity: Broadly check port is up or not , verify response times, Capturing different state of servers etc. Server Utilization metrics.

2.  JVM Heap Metrics:  Java heap size in use vs total allocated heap size for a application server/instance etc.

3.  WorkManagers: No. of active threads(threads in use) vs threads allocated. Stuck threads notification basically Thread usage.

4.  JMS : JMS server availability and JMS destination metrics (number of messages waiting in queue). Current number of destinations vs total instantiated for JMS server.

5.  JDBC : JDBC Connection Pool metrics.

6.  Session Data: Number of active/open sessions and current session invocation time.

7.  JTA metrics: Active transactions and total transaction count.

8.  EJB metrics: Number of beans in pool (current vs total), EJB transactions metrics.

9.  Servlet/JSP : Servlet/JSP Response times.

10. WebServices: Webservice metrics including service hit count and response time.  

Again If you fee this is too much for setup , then I would  go with category 1-5 as mandatory monitoring metrics and from 5-10 will be optional based on application requirement.
