Service availability monitoring limitations
•
Capabilities of third-party monitoring systems are limited
–
–
Can monitor availability and performance at a basic level. Example: response to a basic query to determine
up / down availability and response time (see sample screen shot below)
Cannot determine the availability or correctness of specific functionalities

Service functionality monitoring is effort intensive
•
•
Requires parsing of application logs and outputs
–
Immature code yields false positives and negatives and requires additional resources for interpretation and
remediation
–
Compiling monthly availability reports from incident logs takes significant effort (See Nodal EDS detailed
incident log below for month of July for just 3 applications: SE, LFC and SCED)
Application code that is not ready will lead to rework of monitoring systems and diverts key resources

EDS SLA – Availability Targets and Planned Outage Windows
•
Availability Targets
– 9/01/08 to (168 hour test – 31 days)
• EDS infrastructure and applications (except ICCP): 98%, ICCP: 100%
– (168 hour test – 30 days) onwards
• Production level availability targets
•
Planned Outage windows
– 9/01/08 to (168 hour test – 31 days)
• 8:00 AM – 10:00 AM CT Wednesdays, anytime Saturdays and holidays
• For critical bugs, as determined by EDS PM and Director of IT infrastructure &
Operations and communicated via Market Notices
– (168 hour test – 30 days) onwards
• Production level maintenance windows

EDS SLA - Availability Metrics collection and reporting
•
EDS SLA in review today (v5.3) supports monitoring at capability level
2 discussed in the introductory slide
•
Availability metrics will be collected per the following schedule
– For some EMS and MMS applications currently in EDS: 9/5/2008
– For all other applications currently in EDS: 10/1/2008
– For applications not in EDS: “Deployment in EDS + 1 Month”
•
Availability metrics will be reported monthly
– Report will include current month and YTD availabilities, Detailed Incident log
and Planned Outages log
