The Sun Java Enterprise System Suite

The Sun Java Enterprise System Suite offers a comprehensive list of products for Internet infrastructures, i.e., web server, middleware application server, LDAP server, messaging server, and identity server, that are used in many domains such as banking, trading, healthcare, and logistics to support mission-critical services. IT infrastructures based on the Sun Java Enterprise System Suite follow the popular multi-tier architecture wherein the web server functions as the front-end receiving client requests, the application server hosts the business logic components, the identity server manages user policies, the directory server handles access rights and other user information lookups, and the database server stores and retrieves application data.

Routine monitoring of the infrastructure including the network, system, and application is imperative to ensure that the infrastructure functions at peak performance at all times. Since each Sun Java Enterprise application performs a different, specialized function, the monitoring has to be specific to each application – e.g., is the mail server delivering emails? is the application server’s heap effectively sized?. More importantly, since the different Sun Java Enterprise applications inter-operate to support the end-user service, it is critical that the monitoring system track the inter-dependencies between applications in order to pin-point the exact source of a performance bottleneck in the infrastructure.

The eG Sun Java Enterprise System Monitor

The layer model of a Sun Java System web server

The eG Sun Java Enterprise System monitor offers extensive infrastructure monitoring capabilities for the Sun Java Enterprise System suite. Pre-built models for Sun Java System web, application, directory, and messaging servers dictate what metrics are to be collected by eG agents, what thresholds are to be applied to the metrics, and how the metrics are to be correlated in order to assist with problem diagnosis. eG’s single agent is capable of monitoring all the Sun Java Enterprise System applications running on a server and reporting metrics to a central manager over HTTP/HTTPS. The 100% web-based communication architecture enables IT infrastructure operators to remotely monitor and administer their servers, within and across demilitarized zones. eG’s intelligent thresholding and alarm management capability automatically sets both fixed and multiple thresholds corresponding to different alert levels – critical, major, or minor, thereby assisting the administrator to prioritize and initiate corrective actions.

What the eG Sun Java Enterprise System Monitor Reveals

Sun Java Enterprise System Infrastructure Component	eG Monitoring Capability
Web Server	External monitoring of server availability and responsiveness Internal monitoring of a server’s request processing rate, percentage errors and aborts TRUE web transaction monitoring using the eG web adapter - request rates for each monitored transaction, average processing time at the server and percentage errors, aborts Correlation of server response time with network response times
Web Application Server	Server up/down time monitoring Server throughput tracking in terms of requests and data traffic JDBC connection pool usage levels and connection failure reports Thread pool execution status levels Transaction-related measures including the number of transactions that are completed, rolled back and in-progress EJB caching efficiency, bean pool-related metrics
Directory Server	External monitoring of the directory service health including server availability and response time for a typical request Server usage metrics such as connection rate, data transfer rate, operations backlog, current connections to the server, etc
Messaging Server	External measure of SMTP availability to accept messages, measure of POP3/IMAP availability, number of outstanding e-mails, and round trip time for mail delivery Monitoring of user activity, failed logins, internal message queue lengths, request processing and failure rates, messaging store database activity monitoring including transactions, deadlocks, etc
Sun Solaris Operating System	Monitoring of critical OS resources including disk space usage and I/O rates, swap memory, CPU utilization TCP/IP connection statistics Network interface usage reports, network connectivity and latency monitoring
