The SightLine™ Performance Power Agent for Unisys ClearPath MCP Systems collects and reports on performance data from both the ClearPath MCP system and all applications running on the system. This data is then analyzed by SightLine Expert Advisor/Vision™ to provide a comprehensive view of ClearPath MCP system behavior and performance. Some of the key collected metrics are described below, divided into the following categories:
- Baseline Metrics
- On-Line Transaction Metrics
- Database Metrics
- Billing Accounts and Event Reporting
- BNAv2 Metrics
- TCP/IP Metrics
- Disk Space Metrics.
Processor – Processor utilization is an important measure of system capacity. SightLine monitors processor resources based on user and MCP utilization, activation rates and queuing delays. Each processor-related category contains data that enables a more in-depth analysis of how your processor resources are being used across all system users.
Application – SightLine collects application metrics such as Order Counts, Dollar Volumes, and Accounts Processed, and then correlates this data with system performance and capacity usage measures.
Memory – SightLine reports on the amount of available and in-use memory, the overlay activity of in-use memory, and the users of memory resources. Memory-related statistics help you to detect memory constraints that can lead to performance bottlenecks.
I/O – SightLine reports on key I/O performance metrics (Percent Busy, I/Os per Second, Seconds per I/O, etc.) in four categories: I/O Processor (IOP), Subsystem, Unit, and Family. This data helps to minimize I/O bottlenecks and to optimize I/O activity allocation in order to improve system throughput.
Network – For each Network Processor (NP or ICP), SightLine reports I/O traffic rates for Reads, Writes, Average I/O Times, Queue Depth and other key metrics. For Network Support Processor (NSP), SightLine reports on I/O’s and Kbytes Transferred per second, divided into reads and writes. This network-related data is crucial to improving the efficiency of your communications line and system-to-LAN/WAN interface.
Workload – SightLine performs workload analysis at two levels: Individual Transaction Type and Workload Class. Each transaction type can be measured by Rate per Second, CPU Time, Response Time, Queue Time and other transaction-related metrics. Each user-defined workload class can be measured by Mix Count, CPU, I/O and Memory utilization and ReadyQ Percent, and can include its own unique performance objective.
Worst Offenders – SightLine EA/V’s EventList window displays real-time and historical data for the programs and tasks that consume the most processor, I/O and memory resources. Data can be sorted by user-selected resource criteria, busiest BNA lines or TCP connections, or busiest DMSII data sets and access structures. Event data enables you to diagnose application issues at the program and database structure level, in order to identify which communications facilities are experiencing the highest volume of activity.
COMS response time is a critical measure of end-user performance. The COMS Interface Agent provides transaction data for each COMS program, program group, user, trancode (LINC ISPEC), window and station. Available metrics include: Transactions per Second, Average Response Time, Average Queue Depth, ReadyQ Time, and a Response Time/Transaction Count Histogram. COMS statistics can be used to analyze online transaction issues and to project transactional growth for capacity planning purposes.
The DMSII Database Interface Agent provides data for each active DMSII database in your system. This includes utilization and performance metrics (Transactions per Second, I/Os per Second, Buffer Counts, etc.) on four successive levels of monitoring: Global Statistics Only, Global plus a Summary of All Structures, Individual Structure Statistics, and Audit Statistics. SightLine also displays the busiest structures in the SightLine EA/V EventList window.
The Billing Accounts and Event Reporting Interface Agent reads the system SUMLOG to provide resource statistics for each job, task, and MCS session run on the system. Custom categories can then be defined and used as for chargeback purposes. Billing-related data helps summarize resource consumption based on billing account or workload, which can supplement workloads data used for capacity planning purposes.
The Accounting Interface Module can also be used to track system outage events and any user-entered events. This is useful for monitoring system and application service availability, or any data center or user-defined events.
The BNAv2 Interface Agent provides automated access to network statistics on the ClearPath MCP host for the NP’s or ICP’s, as well as the CP2000 and CP2000 line modules. This includes detailed statistics at the line and station level, and an available display of the busiest lines in the SightLine EA/V EventList window.
The TCP/IP Interface Agent provides automated access to network statistics for every TCP/IP LAN connection on the ClearPath MCP host. This includes TCP-specific metrics that enable you to monitor individual LAN throughput and error rates, and a display of the busiest TCP connections in the SightLine EA/V EventList window.
The Disk Accounting Interface Agent helps you to define and automatically maintain disk-related accounts based on individual users, groups of users, or application. Accounts can be categorized by Usercode, File Name, Days since Last Access or other available keys. Disk accounts are useful for space usage chargeback, as well as helping you efficiently allocate current space resource and proactively plan for future needs.
The SightLine Capacity Power Agent can also be used to analyze space usage trends, which helps in reallocating existing pack units and proposing additional pack storage.
