Synopsis

Documentation

data DCCategory Source

The possible classes a data collector can belong to.

Constructors

DCInstance
DCStorage
DCDaemon
DCHypervisor
DCNode

Instances

Bounded DCCategory
Enum DCCategory
Eq DCCategory
Read DCCategory
Show DCCategory
JSON DCCategory	The JSON instance for DCCategory.

getCategoryName :: DCCategory -> StringSource

Get the category name and return it as a string.

categoryNames :: Map String DCCategory Source

data DCStatusCode Source

The possible status codes of a data collector.

Constructors

DCSCOk	Everything is OK
DCSCTempBad	Bad, but being automatically fixed
DCSCUnknown	Unable to determine the status
DCSCBad	Bad. External intervention required

Instances

Eq DCStatusCode
Ord DCStatusCode
Show DCStatusCode
JSON DCStatusCode	The JSON instance for CollectorStatus.

data DCStatus Source

The status of a "status reporting data collector".

Constructors

DCStatus
Fields dcStatusCode :: DCStatusCode dcStatusMessage :: String

Instances

Eq DCStatus
Show DCStatus
JSON DCStatus
ArrayObject DCStatus
DictObject DCStatus

loadDCStatus :: JSValue -> Result DCStatus Source

saveDCStatus :: DCStatus -> JSValueSource

data DCKind Source

The type representing the kind of the collector.

Constructors

DCKPerf	Performance reporting collector
DCKStatus	Status reporting collector

Instances

Eq DCKind
Show DCKind
JSON DCKind	The JSON instance for CollectorKind.

data DCVersion Source

Type representing the version number of a data collector.

Constructors

DCVerBuiltin
DCVersion String

Instances

Eq DCVersion
Show DCVersion
JSON DCVersion	The JSON instance for DCVersion.

data CollectorData Source

Type for the value field of the CollectorMap below.

Constructors

CPULoadData (Seq (ClockTime, [Integer]))
InstanceCpuLoad (Map String (Seq (ClockTime, Double)))

Instances

NFData CollectorData

type CollectorMap = Map String CollectorData Source

Type for the map storing the data of the statefull DataCollectors.

data DCReport Source

This is the format of the report produced by each data collector.

Constructors

DCReport
Fields dcReportName :: String dcReportVersion :: DCVersion dcReportFormatVersion :: Int dcReportTimestamp :: Integer dcReportCategory :: Maybe DCCategory dcReportKind :: DCKind dcReportData :: JSValue

Instances

Eq DCReport
Show DCReport
JSON DCReport
ArrayObject DCReport
DictObject DCReport

loadDCReport :: JSValue -> Result DCReport Source

saveDCReport :: DCReport -> JSValueSource

addStatus :: DCStatus -> JSValue -> JSValueSource

Add the data collector status information to the JSON representation of the collector data.

mergeStatuses :: (DCStatusCode, String) -> (DCStatusCode, [String]) -> (DCStatusCode, [String])Source

Helper function for merging statuses.

buildReport :: String -> DCVersion -> Int -> Maybe DCCategory -> DCKind -> JSValue -> IO DCReport Source

Utility function for building a report automatically adding the current timestamp (rounded up to seconds). If the version is not specified, it will be set to the value indicating a builtin collector.

data ReportBuilder Source

A report of a data collector might be stateful or stateless.

Constructors

StatelessR (IO DCReport)
StatefulR (Maybe CollectorData -> IO DCReport)

type Name = StringSource

data DataCollector Source

Type describing a data collector basic information

Constructors

DataCollector

Fields

dName :: Name: Name of the data collector
dCategory :: Maybe DCCategory: Category (storage, instance, ecc) of the collector
dKind :: DCKind: Kind (performance or status reporting) of the data collector
dReport :: ReportBuilder: Report produced by the collector
dUpdate :: Maybe (Maybe CollectorData -> IO CollectorData): Update operation for stateful collectors.
dActive :: Name -> ConfigData -> Bool: Checks if the collector applies for the cluster.
dInterval :: Name -> ConfigData -> Integer: Interval between collection in microseconds
