exceededforasustainedperiod,AppSpeedgeneratesanevent.
YoucanmanuallymonitoreventsoryoucanconfigureAppSpeedtosendemail

SLA States
AppSpeedusesstatechangestogenerateevents.Thestateofatransactionisbasedonitscompliancetothe
definedlatencyanderrorthresholds.
Thestateofanapplicationreflectstheworststateofanyofitstransactions.Forexample,ifthestateofallthe
transactionsisOK,thestate
oftheapplicationisOK.IfthestateofanytransactionisNotAvailable,the
applicationstateisNotAvailable.
Youcanviewthereal‐timestatesforallapplicationsorforthetransactionsofaselectedapplication.See“View
States”onpage 13
Configuring SLA Thresholds
Youcandefinethelevelsatwhichstatechangesoccurinresponsetounsatisfactoryperformanceasmeasured
bylatencyandthepercentageoferrors.Youconfigurethresholdsforeachtransaction.
Whenaperformancelevelexceedsadefinedthresholdforasustainedperiod,achangeinstateoccurs.Specific
thresholdsaredefined
foreachstatebasedonthedegreeofanapplication’scompliancewithordeviationfrom
targetSLAlevels.Thetransitionbetweenstatesoccursaccordingtodeviationfromthethresholdsdefinedfor
warning,SLAviolation,andunavailablestatesforthegiventransaction.
Youcanenableordisableperformancemonitoringforeachapplication
orforeachtransaction.See“Enableor
DisableSLAMonitoringofTransactions”onpage 35.
