func IsBlacklisted ¶
IsBlacklisted returns a boolean indicating if the given command is blacklisted by our config.
func NewDefaultTransport ¶
NewDefaultTransport provides a http transport configuration with sane default timeouts
func SysProbeConfigFromConfig ¶
func SysProbeConfigFromConfig(cfg *AgentConfig) *ebpf.Config
SysProbeConfigFromConfig returns a valid tracer-bpf config sourced from our agent config

}
AgentConfig is the global config for the process-agent. This information is sourced from config files and the environment variables.
func NewAgentConfig ¶
func NewAgentConfig(loggerName config.LoggerName, yamlPath, netYamlPath string) (*AgentConfig, error)
NewAgentConfig returns an AgentConfig using a configuration file. It can be nil if there is no file available. In this case we'll configure only via environment.
func NewDefaultAgentConfig ¶
func NewDefaultAgentConfig(canAccessContainers bool) *AgentConfig
NewDefaultAgentConfig returns an AgentConfig with defaults initialized
func NewSystemProbeConfig ¶
func NewSystemProbeConfig(loggerName config.LoggerName, yamlPath string) (*AgentConfig, error)
NewSystemProbeConfig returns a system-probe specific AgentConfig using a configuration file. It can be nil if there is no file available. In this case we'll configure only via environment.
func (AgentConfig) CheckInterval ¶
func (a AgentConfig) CheckInterval(checkName string) time.Duration
CheckInterval returns the interval for the given check name, defaulting to 10s if not found.
func (AgentConfig) CheckIsEnabled ¶
func (a AgentConfig) CheckIsEnabled(checkName string) bool
CheckIsEnabled returns a bool indicating if the given check name is enabled.
func (*AgentConfig) LoadProcessYamlConfig ¶
func (a *AgentConfig) LoadProcessYamlConfig(path string) error
LoadProcessYamlConfig load Process-specific configuration
type DataScrubber ¶
type DataScrubber struct {
Enabled bool
StripAllArguments bool
SensitivePatterns []*regexp.Regexp
// contains filtered or unexported fields
}
DataScrubber allows the agent to blacklist cmdline arguments that match a list of predefined and custom words
func NewDefaultDataScrubber ¶
func NewDefaultDataScrubber() *DataScrubber
NewDefaultDataScrubber creates a DataScrubber with the default behavior: enabled and matching the default sensitive words
func (*DataScrubber) AddCustomSensitiveWords ¶
func (ds *DataScrubber) AddCustomSensitiveWords(words []string)
AddCustomSensitiveWords adds custom sensitive words on the DataScrubber object
func (*DataScrubber) IncrementCacheAge ¶
func (ds *DataScrubber) IncrementCacheAge()
IncrementCacheAge increments one cycle of cache memory age. If it reaches cacheMaxCycles, the cache is restarted
func (*DataScrubber) ScrubCommand ¶
func (ds *DataScrubber) ScrubCommand(cmdline []string) ([]string, bool)
ScrubCommand hides the argument value for any key which matches a "sensitive word" pattern. It returns the updated cmdline, as well as a boolean representing whether it was scrubbed
func (*DataScrubber) ScrubProcessCommand ¶
func (ds *DataScrubber) ScrubProcessCommand(p *process.FilledProcess) []string
ScrubProcessCommand uses a cache memory to avoid scrubbing already known process' cmdlines
type WindowsConfig ¶
type WindowsConfig struct {
// Number of checks runs between refreshes of command-line arguments
ArgsRefreshInterval int
// Controls getting process arguments immediately when a new process is discovered
AddNewArgs bool
}
WindowsConfig stores all windows-specific configuration for the process-agent.
