Neat idea. I'm not sure how much impact it will have on the backend, but it will be good to have customers be aware when policies are misconfigured.
The flapTracker is another cache that can grow unbounded as new policies are created. Do you think we should clear the entry when a policy is deleted? I guess it depends if there are types of flapping where resources are continually created and deleted.

Hey @jeswanke this is getting closer, but I have some concerns and I've converted the Jira Bug to be a Story, because I think we'll need QE validation on this.
- I don't think the alerts look good in the current placement with their rounded corners right up against square borders.
- If there are multiple resources flapping, which is quite likely...
- The alerts could fill the screen
- The user has to dismiss each of them individually
- The exact same message except for resource name is repeated over and over
- There are plural issues in the string. Would need to use nested strings like the hostCount/infraEnvCount to have multiple plurals.
- Alert dismissal should probably be stored in local storage
So I think the alerts need some desigin work. Might need a consultation with @imjoyjean to assess whether there is a good way to display alerts like this within ACM pages, or if the console backend should just generate an OCP alert. Or maybe it would make more sense to only do this for policies and mark the policies themselves?

@jeswanke I think this is a better design.
We might need a bit of tuning though:
- New policies are immediately detected as flapping. Probably because the status gets computed. We don't want this warning to show up under the normal course of events.
- I created 2 conflicting policies,
kevin-barandkevin-bazthat fight over a ConfigMap. (See sample YAML below.) These are not consistently shown as flapping. Might need a bit more research into how often these would be checked and whether that is adjustable. But I think we should at least work well with the defaults.

I think we can work on the microcopy content to make it shorter and more direct here. I do like it as a icon + tooltip. Question - what does it mean really for the user to check this configuration? Is it to review it to resolve some sort of loop update states, or are they doing this manually? I want to make sure we give them more direction to resolve the situation. @KevinFCormier @jeswanke |
This might need some more input from the GRC team. I know one thing that can be wrong is you could have policies with enforce enabled that directly conflict with each other, alternately changing the state of resources each time they are reconciled. I assume there might be other types of issues that could cause this. CC @JustinKuli |
Ok, I just wanted to make sure the text covers that generally. Is it always 1 per minute? What do you think about something like "Check for policy configuration conflicts. Due to high activity, updates are limited to 1 per minute." |

A debug settling value is active and the production value is commented out. Line 78 sets FLAP_SETTLING_MS to 3 minutes. The documented value in the header comment at line 72 is 15 minutes, which matches the commented-out line 77. Remove the dead line and set the intended value before merge.

The spec-change reset is not durable, and the test does not detect it. refreshThrottleStatus deletes polling and throttled on a spec change, but keeps the accumulated timestamps. The next update with the same spec pushes one timestamp, the window count is still above FLAP_THRESHOLD, and polling returns immediately.

Count-based deduplication misses membership changes. The guard compares only throttledResources.length with lastFlappingResourceCount. If one Policy stops being throttled and another starts within the same refresh, the length is unchanged and no THROTTLED event is pushed. Clients then show the previous policy as throttled indefinitely.
Compare the resource identities instead of the count.
🔧 Proposed fix
- if (throttledResources.length !== lastFlappingResourceCount) {
- lastFlappingResourceCount = throttledResources.length
+ const signature = throttledResources
+ .map((r) => `${r.kind}/${r.namespace}/${r.name}`)
+ .sort()
+ .join(',')
+ if (signature !== lastFlappingSignature) {
+ lastFlappingSignature = signatureReplace lastFlappingResourceCount with lastFlappingSignature: string | undefined at line 92 and in resetFlapTracker.

Update policiesState from THROTTLED resources and remove the log. The handler only logs data.resources; it does not update policiesState. Because PolicyTableCell renders the indicator from item.policy.throttled, resources reported only by this event cannot display the indicator.

This is a nice idea and overall I think it's looking pretty good!
There are a few situations where this kind of thing will occur: as mentioned, if two Policies incompatibly manage the same resource, they will fight with each other; or similarly if another controller on the cluster manages the same object as a policy, they may conflict and both repeatedly update it. There used to be cases where this would just happen with one Policy - for example if some default fields were dropped by the API server, the Policy would keep noticing them as missing and say it was updating them - but I think/hope we've fixed all of those bugs by now. Just FYI.

I have a nitpick with the wording here: "Updates are being limited" might make users think the evaluationInterval (or something similar) has been automatically set on these Policies in order to slow them down - but really it's just that updates in the UI are being limited, right?
Maybe something like The state of the ${kind} will only be visually updated here ${timesPerMinute} times per minute would be more clear?

Exercise a populated-to-populated specification change.
throttlePolicyAt passes policies without spec to every shouldThrottleResource call. Therefore, resourceSpecKey stores {} in lastSpec, and the final assertion tests a transition from {} to {"disabled":true}. It does not test a transition from {"disabled":false} to {"disabled":true}. Pass the baseline spec through throttlePolicyAt and use it for each throttling call.

Preserve root Policy throttle state.
usePolicies returns root Policies, while useAddRemediationPolicies matches propagated Policies separately. The backend can set throttled: true on a root Policy before caching it. When no propagated Policy is throttled, getPolicyRemediation deletes that root flag. PolicyTableCell then omits the warning icon because it requires item.policy.throttled === true.
Preserve either source of throttle state.

📝 Summary
A policy resource is prevented from flapping and this alert is shown in console:
thresh hold parameter
export const FLAP_THRESHOLD = 5 // N: modifications that trigger flapping detection
export const FLAP_WINDOW_MS = 5 * 1000 // M: sliding window for counting modifications
export const FLAP_COOLDOWN_MS = 60 * 1000 // P: min interval between browser updates while flapping
export const FLAP_THROTTLE_KINDS = ['Policy'] // kinds subject to flapping detection
where:
If the same resource kind/name/namespace is modified more then N times in M seconds, only one event is sent per P minutes
to test:
TEST_THROTTLING=true npm run plugins
