Constants

const DefaultMaxConcurrentRequests = 2

DefaultMaxConcurrentRequests determines the maximum number of requests in-flight for a given handler We choose 2 because one is for regular agent checks and another one is for manual troubleshooting

Functions

func WithConcurrencyLimit

func WithConcurrencyLimit(limit int, original func(http.ResponseWriter, *http.Request)) func(http.ResponseWriter, *http.Request)

WithConcurrencyLimit enforces a maximum number of concurrent requests over a certain HTTP handler function

func WriteAsJSON

func WriteAsJSON(w http.ResponseWriter, data interface{})

WriteAsJSON marshals the give data argument into JSON and writes it to the `http.ResponseWriter`

Types

type MemoryMonitor

type MemoryMonitor = cgroups.MemoryController

MemoryMonitor monitors cgroups' memory usage

func NewMemoryMonitor

func NewMemoryMonitor(kind string, containerized bool, pressureLevels map[string]string, thresholds map[string]string) (*MemoryMonitor, error)

NewMemoryMonitor instantiates a new memory monitor
