Database.Sybase.Sysmon.Log

The module provides the generic api to parse the logs, to store the parsed data in the IntervalMap and to query data from the IntervalMap based on the given time interval.

Documentation

data Interval v

A closed interval. The lower bound should be less than or equal to the higher bound.

Instances

Averageable LogInterval

Eq v => Eq (Interval v)

Ord v => Ord (Interval v)

Show v => Show (Interval v)

type LogRequest = Maybe LogInterval

The request time interval to query sysmon reports. If the value of the request interval is Nothing the default max time interval request will be used. See function maxInterval below.

merge :: LogEntry a => LogTree a -> LogTree a -> LogTree a

Merge two log trees

parse :: LogEntry a => FilePath -> IO (LogTree a)

Generic parse the log files and store the data in the log tree. To parse sysmon logs use parseSysmon from SysmonLog package. This package implements Sysmon instance of LogEntry class (see Sample.hs)

hints :: (Averageable a, LogEntry a) => LogRequest -> ConfigParser -> LogTree a -> [Hint]

Max interval to cover all intervals in the log tree

Get hints for the average sysmon report corresponding to the request time interval. To override the default hints parameters use ConfigFile api. See HConfig data type in SysmonTypes package for the list of the configuartion parameters.

fmtHints :: [Hint] -> Doc

Pretty print the hints

average :: (Averageable a, LogEntry a) => LogRequest -> LogTree a -> a

Average sysmon report corresponding to the requested time interval

list :: LogEntry a => LogRequest -> LogTree a -> [a]

Get log reports which intersecs with the requested time interval

intervals :: LogEntry a => LogRequest -> LogTree a -> [LogInterval]

Get intervals which intersect with the requested interval

hasInterval :: LogEntry a => LogRequest -> LogTree a -> Bool

Check if the log tree contains an interval corresponding to the requested time interval

mkInterval :: UTCTime -> UTCTime -> LogInterval

Create log time interval
