func CreateTcpdumpHookIfEnabled ¶

func CreateTcpdumpHookIfEnabled() *backenddisruption.TcpdumpSamplerHook

CreateTcpdumpHookIfEnabled creates a tcpdump hook if DEBUG_ENABLE_TCPDUMP is enabled.

func FindOverlap ¶

func FindOverlap(intervals monitorapi.Intervals, overlapsWith monitorapi.Interval) monitorapi.Intervals

FindOverlap finds any intervals that overlap with the given interval.

func IntervalsOverlap ¶

func IntervalsOverlap(interval1, interval2 monitorapi.Interval) bool

IntervalsOverlap checks if two intervals overlap in time

func IsTransientAPIError ¶ added in v1.6.0

func IsTransientAPIError(err error) bool

func MoveTcpdumpToStorage ¶

func MoveTcpdumpToStorage(tcpdumpHook *backenddisruption.TcpdumpSamplerHook, storageDir string)

MoveTcpdumpToStorage moves tcpdump pcap files to the storage directory if the hook is not nil. This should be called in the WriteContentToStorage method of monitor tests. It logs any errors but doesn't fail the entire storage operation.

func RetryWithExponentialBackoff ¶ added in v1.6.0

func RetryWithExponentialBackoff(ctx context.Context, fn func() error) error

func StopTcpdumpCollection ¶

func StopTcpdumpCollection(tcpdumpHook *backenddisruption.TcpdumpSamplerHook)

StopTcpdumpCollection stops tcpdump collection if the hook is not nil. This should be called in the CollectData method of monitor tests.

func SystemdJournalLogTime ¶

func SystemdJournalLogTime(logLine string, year int) time.Time

SystemdJournalLogTime returns Now if there is trouble reading the time. This will stack the event intervals without parsable times at the end of the run, which will be more clearly visible as a problem than not reporting them.
