Description

CA eHealth helps you take corrective action before business processes are negatively impacted by collecting and analyzing key performance information across the IT infrastructure, providing both real-time and predictive performance analysis.

 

 

How CA eHealth works

CA eHealth helps you take corrective action before business processes are negatively impacted by collecting and analyzing key performance information across the IT infrastructure, providing both real-time and predictive performance analysis.

 

Collect

The CA eHealth poller collects performance and availability statistics from a wide variety of vendor devices, including network, system (physical and virtual), and database devices. The polling interval can be set at various rates, including a fast rate of 30 seconds, a normal rate of 5 min, and a slow rate of 15 min. An import poller is also available that bulk transfers information into the eHealth database.

 

Analyze & detect

Dynamic real-time monitoring intelligence is based on patented technology that is used to understand threshold violations within a historical context and help assure that only persistent degradation problems are reported.

  • The Time Over Threshold (TOT) algorithm compares the value of each KPI at each poll to a predefined threshold and reports if the value has been “too wrong for too long.” Instead of generating a trap each time the threshold is crossed, the algorithm determines the aggregate duration of violations within a monitoring window to filter out spikes and determine real, persistent problems.
  • The Deviation from Normal (DFN) algorithm uses historical data to establish a baseline for what is normal behavior for your business. DFN monitors infrastructure component behavior (i.e., KPI values) within each monitoring window (e.g., hour of each day, day of week, etc.) and then assesses whether the current behavior deviates from that norm. The algorithm gradually adjusts normal thresholds, based on the rolling average over the previous six weeks, to reflect the dynamic, changing state of your business.

Diagnose

Sophisticated performance reporting is at the heart of CA eHealth, which combines historical and real-time metrics with intelligent analysis to generate out-of-the-box, role-based views that are used to understand when, where, and how to avoid developing performance degradations before service quality is jeopardized. These reports provide a wide range of perspectives for triage and remediation:

  • At-a-Glance reports At-a-Glance reports provide a comprehensive view of the availability and performance of a particular IT resource, displaying the key statistics over a specified time interval. By automatically capturing performance data and presenting it uniformly, these reports can help significantly reduce the time spent troubleshooting.
  • Health reports These reports evaluate the health of a group of IT components by comparing current performance to historical performance over the course of a day, week, or month. The report provides a list of situations to watch and identifies errors, unusual utilization rates, or volume shifts that warrant investigation. You can easily spot the overall status of a component by its health index, a value that CA eHealth bases on multiple variables.
  • Trend reports CA eHealth generates Trend reports that track the value of one or more performance variables over a period of time. Because of its flexibility, you can use a Trend Report to reveal traffic patterns over time, and relationships between IT components and between variables. Components that you can track this way include CPUs, disks, LANs, WANs, databases, processes and process sets, user or system partitions, and more.
  • MyHealth reports Displayed in the CA eHealth Web interface, MyHealth reports are easily tailored to meet the unique needs of any individual user. They can include any collection of trend charts from the wide range of CA eHealth reports that are critical to a particular user’s job function (for example, database, server, WAN, and application availability performance, all related to a specific IT service).
  • Service Availability reports By performing regularly scheduled tests on IT services, you can watch over your critical business applications—from email to SAP to ecommerce. Common examples are: ping testing for connectivity across sites, measuring time to load a URL to test Web page performance and availability, and measuring specific SQL calls across a network to a server.
  • Service Level reports These reports demonstrate overall QoS across different classes of service and document compliance with internal and external SLAs. You can adapt them to your specific business by defining service level goals, core thresholds, and other performance metrics. There are views tailored for business executives, IT managers, and service customers.
  • Application Response reports These reports help you troubleshoot performance problems quickly to help minimize their impact and examine long-term trends for application tuning and capacity planning. To identify bottlenecks, these reports illustrate network transmission, client processing, and server processing times as percentages of the total response time.
  • Top N reports A tabular Top N report sorts the elements that meet some user-defined criteria. For example, you can use it to find the best, worst, fastest, slowest, or least-utilized circuits, servers, databases, and more. Top N reports can be scheduled to run automatically at specified intervals, and they also make a useful on-demand tool.
  • Traffic Analysis reports Traffic analysis capabilities let you monitor traffic across Cisco NetFlow routers and standard RMON2 probes. These reports show you who is saturating a particular link and what protocols and applications she/he is using. You can view network resource consumption by users, business units, regions, or applications, and use this mechanism to allocate costs back to individual departments.
  • Voice Quality reports In addition to the voice, data, and QoS monitoring for converged network performance management found in CA eHealth Live Health, CA eHealth provides additional IP telephony management services. These include the Voice Quality Monitor for ongoing quality assurance and the integration of the Cisco IP SLA Jitter MOS test into CA eHealth with reporting.

In addition to providing these out-of-the-box, role-based reports, you can customize your reports using templates or can create completely from scratch.

 

Display & Alert

The CA eHealth Live Health Application provides four related real-time displays for monitoring and visualizing the performance of your infrastructure, its components, and the services it supports: Live Trend, Live Exceptions, Live Status, and Live Reporting. Notification levels include normal, warning, minor, major, and critical.
