Overview of LogMate Activity Analysis Tools
LogMateAMS is a complete solution for alarm
management, including alarm activity analysis,
configuration documentation and analysis, alarm
rationalization, and management of change. This
document explains in practical detail the major functions
and purposes of LogMate alarm activity analysis.
LogMateAMS activity analysis covers typical categories as
well as some highly advanced tools that are only available
to LogMateAMS users.
Alarm Activity Analysis Types
Flood
A flood analysis identifies the start and end of an alarm
flood and displays the total number of alarms activated as
well as the duration of the flood. The definition of "flood" is
configurable by the user in terms of alarms per period of
time. Results disclose the number, duration, and intensity
of floods for the time period in question.
Alarm State
The alarm state analysis relates alarm activity to alarm
clears and operator acknowledgements. The gap between
activations and acknowledgements indicates an alarm's
perceived value or the ability to fully assess the alarm's
meaning during runtime.
Nuisance
A nuisance analysis distinguishes chronically overactive
alarm behavior from short-term increases in activity. When
an alarm is returned in the top results of a frequency
analysis it is not This clarifies whether the activity is
spread over a long or short term, i.e is it a long-standing
nuisance or something that recently started?
Frequency
A frequency analysis performs basic alarm record counts.
Results are used to determine the most significant source
of alarm activity, based on the applied criteria. Typical
findings include the most active single alarm, the most
active shift or hour, or even the most active instrument.
Duration
A duration analysis calculates the time that passes
between each alarm activation, acknowledgement, and
return to normal. Results are used to investigate operator
behavior and alarm duration. Typical findings include
alarms that operators are slow to acknowledge or alarms
that remain active for an unusually long time.
Chattering
A chattering analysis highlights instruments that toggle
between normal and abnormal many times in a very short
period. Results typically indicate a failing or miscalibrated
instrument or an alarm trip point that is too close to normal
operating limits.
Related
A related analysis finds recurring sequences in alarm
activity. Results are used to evaluate alarm redundancy or
duplication. Typical findings include two or more alarms
reacting to the same condition or a chain of alarms that
can be traced to the same root.
Custom Analysis
SQL Server Reporting Services®
LogMate is an open architecture product that allows
integration of other reporting tools. SQL Server Reporting
Services (SSRS) is a report writing environment integrated
into SQL ServerŪ. SSRS allows any number of custom
alarm analysis reports to be written and integrated into the
LogMate interface.
TiPS gladly participates in coauthoring of custom reports
in the event that standard LogMate analysis reports do not
cover every need. With Reporting Services, report designs
are virtually unlimited, yet the thin-client architecture
remains intact.
We are happy to further discuss the benefits of all of the powerful analysis tools in LogMate.
