Functions ¶
func AddCommand ¶
func AddCommand(cmd string, format int, post PostProcessor, desc, usage string)
AddCommand adds an additional command to the set of commands accepted by pprof. This enables extensions to add new commands for specialized visualization formats. If the command specified already exists, it is overwritten.
func CleanupTempFiles ¶
func CleanupTempFiles() error
cleanupTempFiles removes any temporary files selected for deferred cleaning.
func CurrentConfig ¶
func CurrentConfig() config
func FetchProfiles ¶
FetchProfiles fetches and symbolizes the profiles specified by s. It will merge all the profiles it is able to retrieve, even if there are some failures. It will return an error if it is unable to fetch any profiles.
func GenerateRawReport ¶
func GenerateReport ¶
func PProf ¶
PProf acquires a profile, and symbolizes it using a profile manager. Then it generates a report formatted according to the options selected through the flags package.
func SetDefaults ¶
SetDefaults returns a new plugin.Options with zero fields sets to sensible defaults.
func SetVariableDefault ¶
func SetVariableDefault(variable, value string)
SetVariableDefault sets the default value for a pprof variable. This enables extensions to set their own defaults.
Types ¶
type GoFlags ¶
type GoFlags struct {
UsageMsgs []string
}
GoFlags implements the plugin.FlagSet interface.
func (*GoFlags) AddExtraUsage ¶
AddExtraUsage implements the plugin.FlagSet interface.
func (*GoFlags) ExtraUsage ¶
ExtraUsage implements the plugin.FlagSet interface.
func (*GoFlags) StringList ¶
StringList implements the plugin.FlagSet interface.
type PostProcessor ¶
PostProcessor is a function that applies post-processing to the report output
