Documentation

options :: [OptType] Source

Options list and functions.

data Phase Source

The allocation phase we're in (initial, after tiered allocs, or after regular allocation). Constructors PInitial PFinal PTiered

data SpecType Source

The kind of instance spec we print. Constructors SpecNormal SpecTiered

specPrefix :: SpecType -> String Source

What we prefix a spec with.

specDescription :: SpecType -> String Source

The description of a spec.

effFn :: (CStats -> Integer) -> (CStats -> Double) -> CStats -> Double Source

Efficiency generic function.

memEff :: CStats -> Double Source

Memory efficiency.

dskEff :: CStats -> Double Source

Disk efficiency.

cpuEff :: CStats -> Double Source

Cpu efficiency.

statsData :: [(String, CStats -> String)] Source

Holds data for converting a CStats structure into detailed statictics.

specData :: [(String, RSpec -> String)] Source

List holding RSpec formatting information.

clusterData :: [(String, CStats -> String)] Source

List holding CStats formatting information.

printStats :: Phase -> CStats -> [(String, String)] Source

Function to print stats for a given phase.

printResults :: Bool -> List -> List -> Int -> Int -> [(FailMode, Int)] -> IO () Source

Print final stats and related metrics.

printFinal :: Bool -> IO () Source

Prints the final OK marker in machine readable output.

tieredSpecMap :: [Instance] -> [(RSpec, Int)] Source

Compute the tiered spec counts from a list of allocated instances.

formatSpecMap :: [(RSpec, Int)] -> [String] Source

Formats a spec map to strings.

formatRSpec :: Double -> String -> RSpec -> [(String, String)] Source

Formats "key-metrics" values.

printAllocationStats :: Double -> List -> List -> IO () Source

Shows allocations stats.

ensureQuoted :: String -> String Source

Ensure a value is quoted if needed.

printKeys :: [(String, String)] -> IO () Source

Format a list of key/values as a shell fragment.

printInstance :: List -> Instance -> [String] Source

Converts instance data to a list of strings.

printAllocationMap :: Int -> String -> List -> [Instance] -> IO () Source

Optionally print the allocation map.

formatResources :: a -> [(String, a -> String)] -> String Source

Formats nicely a list of resources.

printCluster :: Bool -> CStats -> Int -> IO () Source

Print the cluster resources.

printISpec :: Bool -> RSpec -> SpecType -> DiskTemplate -> IO () Source

Prints the normal instance spec.

printTiered :: Bool -> [(RSpec, Int)] -> Double -> List -> List -> [(FailMode, Int)] -> IO () Source

Prints the tiered results.

printClusterScores :: List -> List -> IO () Source

Displays the initial/final cluster scores.

printClusterEff :: CStats -> IO () Source

Displays the cluster efficiency.

failureReason :: [(FailMode, Int)] -> String Source

Computes the most likely failure reason.

sortReasons :: [(FailMode, Int)] -> [(FailMode, Int)] Source

Sorts the failure reasons.

main :: IO () Source

Main function.
