A structure that holds the constructor parameters for the FrequencyStatus class.
Manages a list of diagnostic tasks, and calls them in a rate-limited manner.
A diagnostic task that monitors the frequency of an event.
Diagnostic task to monitor the interval between events.
DiagnosticTask is an abstract base class for collecting diagnostic data.
Wrapper for the diagnostic_msgs::DiagnosticStatus message that makes it easier to update...
