PERTAIN_TOProblem

Errors from an ASP.NET Core 7 app are not appearing in Sentry, and the console shows `CSRF Verification Failed A required security token was not found or was invalid`.

PERTAIN_TOProblem

I also do not want call external tools like sentry-cli from script for that purpouse — I need to run Python script without external dependencies so I can not use SDK for python. Tension: I can not google it or find in API reference(there only methods about listing\retrivieng issues/events but not sending them). Outcome: The same way any of the SDKs does: post the data to Sentry API for the given DSN.

PERTAIN_TOSolution

Add the Sentry tracing integration by including `new BrowserTracing()` (along with existing integrations like `CaptureConsole`) in the `Sentry.init({ integrations: [...] })` configuration.

PERTAIN_TOProblem

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.

PERTAIN_TOSolution

Now sentry is also providing decorator out of the box which you directly use like this. — custom script that are lunching by crone and do set of similar tasks. Tension: I want to incorporated sentry_sdk into my script to get performance tracing of my tasks. Outcome: @sentry_sdk.trace.

PERTAIN_TOProblem

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.

PERTAIN_TOSolution

if url.startswith('/ht/'): return 0 # Don't trace any of these transactions — sentry_sdk.init( # ... traces_sampler=traces_sampler, ). Tension: the health check is filling all the Sentry transaction limits. Outcome: return 0.1 # Trace 10% of other transactions.

PERTAIN_TOSolution

Use `sentry_sdk.start_transaction` instead

PERTAIN_TOSolution

Update Sentry initialization to include o.AddAspNet(); and in Application_Error call SentrySdk.CaptureException(Server.CaptureLastError());. For performance monitoring, also set TracesSampleRate and wrap request handling with Context.StartSentryTransaction() / Context.FinishSentryTransaction().

PERTAIN_TOProblem

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

PERTAIN_TOSolution

Disable tracing to reduce payload volume (e.g., set `tracesSampleRate: 0`) until a proper fix is implemented.

PERTAIN_TOProblem

does not produce such a `query_profile.json` file — If you run an `EXPLAIN` or `EXPLAIN ANALYZE` query. Tension: profiling/timing stats to a `query_profile.json`, which I should be able to use to generate an html file. Outcome: the profiling information will not be written to the desired file, but will rather show up in the result.

PERTAIN_TOSolution

If you run a straight `SELECT/UPDATE/DELETE` query, then the profiling information is written to the file. Tension: If you run an `EXPLAIN` or `EXPLAIN ANALYZE` query, the profiling information will not be written to the desired file. Outcome: and the result is the result of the query.

PERTAIN_TOProblem

Querying `pg_stat_user_indexes` gives a long list of results with 0 scans — Primary Instance being used for the (transactional) application and a Read Replica being used for analytical purposes. Tension: we are not sure how to interpret those stats regarding the replicas with enough confidence to drop some of the indexes. Outcome: Can they be different in the primary and replica?

PERTAIN_TOSolution

To determine if an index is unused or not — query the view on the primary and all standby servers. Tension: the transactional and analytical queries are very different. Outcome: query the view on the primary and all standby servers.

PERTAIN_TOProblem

jfrconv with multiple JFR inputs only produces output from the last file

PERTAIN_TOSolution

Use cat to combine the JFR files into one profile.jfr before running jfrconv

PERTAIN_TOProblem

this does not happen — whenever the tracee creates a new thread. Tension: I must also follow all threads created by the traced program.

PERTAIN_TOSolution

To get the effect you want. Tension: you're not resuming the parent before you wait for the child!

PERTAIN_TOReport

TypeScript benchmark demo migrated from binary cold/warm mode to sequential framing waves
