Which of the following are ways to reduce flapping of a detector? (Select all that apply)

Show Suggested Answer Hide Answer
Suggested Answer: D, A

According to the Splunk Lantern articleResolving flapping detectors in Splunk Infrastructure Monitoring, flapping is a phenomenon where alerts fire and clear repeatedly in a short period of time, due to the signal fluctuating around the threshold value. To reduce flapping, the article suggests the following ways:

Configure a duration or percent of duration for the alert: This means that you require the signal to stay above or below the threshold for a certain amount of time or percentage of time before triggering an alert. This can help filter out noise and focus on more persistent issues.

Apply a smoothing transformation (like a rolling mean) to the input data for the detector: This means that you replace the original signal with the average of its last several values, where you can specify the window length. This can reduce the impact of a single extreme observation and make the signal less fluctuating.

Adjusting the gain helps too!

Use a low-pass filter.

Hysteresis, filtering, and dampening. Anything to avoid that disco ball effect on my detectors.

Hysteresis, filtering, and dampening. Gotta love a good detector that doesn't have a mind of its own.

Hysteresis, filtering, and dampening. Flapping detectors are the worst, amirite?

The answer is definitely using hysteresis and dampening. Gotta love those stable detectors!

I think using averaging techniques could help, but I’m not confident if that directly applies to flapping reduction.

I feel like there was something about damping techniques in our study materials, but I can't recall the specifics right now.

I remember practicing a question like this where we discussed using filters to stabilize readings. That might be relevant here too.

I think one way to reduce flapping is by adjusting the threshold levels, but I'm not entirely sure if that's the only method.

Ah yes, I remember now! Adjusting the detector's threshold, incorporating positive feedback, and using a Schmitt trigger - those are all effective ways to minimize flapping. I feel good about this question.

Ugh, I'm drawing a blank on this one. Reducing flapping is an important concept, but I can't recall the specific techniques off the top of my head. Guess I need to review that material again.

Okay, let's see. Reducing noise, adding hysteresis, and using a low-pass filter - those all seem like good strategies to try. I feel pretty confident about those.

Hmm, I remember something about using a damping mechanism or filtering the input signal. I'll have to think that through more carefully.

I think reducing the detector's sensitivity could help reduce flapping. But I'm not totally sure about the other options.
