Graph/health-check-noise-sampling

Pattern

Health Check Noise Sampling

health-check-noise-sampling

A recurring logging/tracing noise shape where health-check endpoints consume Sentry transaction limits, so filtering or URL-based sampling is applied before events are sent (often by returning null or adjusting trace sampling).

we don't have Sentry logging anymore — since we picked Temporal to run our background tasks (workflows and activities). Tension: Is it possible to configure our worker to setup Sentry SDK and forward errors in workflows and activities to Sentry? Outcome: You can configure your worker with a Workflow interceptor.

This is treated by Sentry as an error and being logged into Sentry. — I have some cases in which I am cancelling the token for certain API requests. Tension: I would like cancel token errors to not be logged. Outcome: This has not worked.

Sentry Logger [warn]: Discarded session because of missing or non-string release — Sentry.init({. Tension: but still keep getting.

Sentry sends non-crash log events instead of only fatal crash events

What's the difference between OpenTelemetry and Sentry? — At first glance they look similar with regarding to tracing, logs etc. Tension: However, there should difference between them. Outcome: Sentry is a product, with proprietary SDKs you can use in your application to generate telemetry.

"android::Looper::pollInner" — we are using Sentry as crash reporting tool. Tension: it just shows a bunch of stacktrace lines that cannot help me to find the cause. Outcome: high number of crashes.

Unable to identify whether Sentry event data is APM/transaction data in BeforeSend/BeforeSendTransaction

If the connection is slow or if, for some reason, the Sentry Server is unreachable, it significantly impacts the overall performance of the application. — We are currently experiencing a performance issue with Sentry in PHP, which sends events in real-time through an API call. Tension: the Sentry Server is unreachable. Outcome: Our preference is to log events locally and subsequently send them to Sentry using Fluentbit.

java.lang.NoSuchMethodError: org.springframework.http.server.reactive.ServerHttpResponse.getRawStatusCode()Ljava/lang/Integer;. Outcome: at io.sentry.spring.webflux.SentryWebFilter.finishTransaction(SentryWebFilter.java:149).

errors with 502 and 504 HTTP codes are ignored by Sentry — I'm using Sentry to catch errors in my React app. Tension: some React errors are ignored too. Outcome: I'd like to override this behavior.

I set the traces sample rate to 0.0 so as to stop the transactions being published to sentry — in the spring boot application. Tension: We would be using sentry for error reporting but not for performance monitoring.

Sentry alerts are not appearing in the Sentry panel for a Clojure backend running in a pod, despite manually sending a test event that returns an event ID. Pod logs show transport/network-related debug output including errors like queue overflow or network error.

I want to disable EB health check entries. — I've set up entry in a django project. Tension: I tried to do it with middleware like this. Outcome: It can be done by `traces_sampler`.

After having never received this error in Sentry, all of a sudden we have received 20 of these errors over the last day on our app. — Large Render Blocking Asset / New Issue /static/js/main.779fa2a0.js. Tension: Our website https://cbbanalytics.com/ doesn't have the fastest loading home-page, but we haven't changed anything major in the last day that would lead to this issue. Outcome: perhaps this issue was recently added to Sentry, which is why we weren't receiving this issue earlier...

Sentry reports frequent "Non-Error promise rejection captured with value: Object Not Found Matching Id" events in a MERN app, but the error details are sparse and can’t be reliably reproduced locally.

I would like the ability to see these rules — Sentry has the ability to setup a rule to ignore errors for a certain duration (1 day) or occurrence (< 10 times). Tension: is there a UI or programmatic way to access these? Outcome: Not sure there's a specific API to get this.

custom script that are lunching by crone and do set of similar tasks — Sentry can track performance for celery tasks and API endpoints. Tension: I want to incorporated sentry_sdk into my script to get performance tracing of my tasks.

the health check is filling all the Sentry transaction limits — I have a Django application with a health check endpoint that's using django-health-check. Tension: How can I exclude the health check endpoint in Sentry? Outcome: use a sampling function to control the sample rate according to the URL or other parameters.

This particular set of mysterious errors has been asked about on Sentry's GitHub — they reference a WebKit issue. Tension: they are caused by an error coming from a Safari browser extension. Outcome: can safely be ignored, or filtered.

However the `BeforeSend` is a — I'm trying to use Sentry.AspNetCore (3.22.0) in a AspNetCore Api, but need to filter certain endpoints and events. Tension: I understand the way to do this is to return a null in BeforeSend, however I cannot get this to trigger at all. Outcome: Both the calls to `.AddSentry` are being hit.

How can I log all 4xx and 5xx requests to Sentry? — I added sentry.io integration to a Laravel application. Tension: By default Laravel doesn't report there exceptions. Outcome: you need an override in Hander.php.

Failed to report an error on a session because there is none active. — on the Application Output. Tension: I see the manually captured error on my Sentry Dashboard. However I'm concerned about these warning messages.

The Sentry Performance tab shows no data for a NestJS application even though Sentry is initialized with tracing handlers.

all errors are tracked successfully, but I still haven't found a way to identify if the error reported by Sentry is a common error or is crashing the app — I'm tracking all my app crashes with Sentry. Tension: I still haven't found a way to identify if the error reported by Sentry is a common error or is crashing the app. Outcome: have someone found a way to do it?

Every curl error is sent to Sentry. — There is a Job that works just fine 99% of time. It retries N times. Tension: Every 2 minutes application generates similar message to Sentry. Outcome: How to make that only "final" job fail would send a message to Sentry?

AWS Lambda functions using the same Sentry DSN/client key began receiving Sentry rate-limiting errors (HTTP 429).

there are two non-obvious failure modes that catch you on the second/third table after the first one ships — instrumenting a previously un-scanned table for the privacy pipeline (sanitizeContent + recordPrivacyEvent + enqueuePrivacySweep + privacy_review_status).

the health-checks that freak out because of the larger number of functions — We are running 12 rather small Azure Function on the Flexible Premium Function service plan. Tension: Everything works as expected, it is only the health-checks that freak out. Outcome: we will be implementing our own health-check routine instead.

The Heroku-hosted MERN app receives many automated-looking requests from the same forwarded IP in the same second, with suspicious query/path content (e.g., unexpected “if”/“php” strings). This behavior appears to be scanning or an attack proxy and raises concerns about security and abuse.

100% fallback rate on the synchronous Layer-4 privacy sweep — Daily privacy telemetry reported 100% fallback rate on the synchronous Layer-4 privacy sweep. Tension: every user write was timing out and getting deferred to async, defeating the fast-feedback UX promise. Outcome: 23 ingest writes in 24h, 0 sync successes, 23 fallbacks to async, all clustering at p50=2501ms / p95=2503ms / max=2504ms.
