Product features



Product features

UDoctorCS version 4.0 contains the following major features:

w Filters: Filtering reduces call home events and associated service requests. It also improves Mean Time to Relief (MTTR).

§ HIB filter filters events that exceed the threshold count within a specified time span.

§ Benign filter filters events by using the Allow through Error Table (ATET).

§ Stale event filter filters old events. § Group events filter filters events that belong to a single

configured group within a specified time span. § Time throttle events filter filters events with a specific

symptom code or severity within a specified time span. w Archive of events and logs: UDoctorCS archives events discarded

by the filtration engine. It archives this data for a configured time period and up to a configured size limit in order to monitor storage space.

w Test dial home: AHA sends out a test event and dials to the System Reporting (SYR) system on a weekly basis. This is to ensure that the connectivity mechanism is working properly and to prevent an influx to the Front End Processor (FEP) and SYR every week.

w TRiiAGE on Control Station (TOMS): TOMS helps automate the process of gathering SPCollects and triaging the logs.

w TRiiAGE Real Time (TRT): TRT provides real time analysis and solutions to array events, and thus reduces call home events.

New features

UDoctorCS version 4.0 contains the following additional new features:

w Support for gathering AHA statistics: AHA gathers counts of notifications that reach AHA and tracks how many of them are called home, archived, discarded, and filtered out by a particular filter. After gathering the statistics, AHA will generate the statistics report in the form of an XML file. This will be done on a periodic basis, as configured. The generated statistics file will be bundled with the monthly Control Station captured data (symptom code 5).

w New TRT script for the Power Supply events: Power supply events with the power supply in a faulted state report the “Power Supply Event” test as FAILED. They display the affected device, its EMC serial number, and its EMC part number. They also display the knowledge base article emc282984.

w Support for new Release 33 symptom codes: UDoctor supports the new Release 33 symptom codes.

w Support for Java 7: UDoctor supports Java 7 w TOMS 500MB Check: UDoctor now checks the size of compressed

SPCollects (SPA + SPB) before initiating TRiiAGE ensuring optimal space utilization. For this version the limit is set to 500MB in size.
