Chrome extension which "sniffs" for monitoring SDKs (Sentry, NewRelic, Rollbar, Bugsnag)

detective-scentry's Issues

Add support for detecting Airbrake

Datadog logo to Datadog RUM logo

Can we add a DD_RUM logo? i.e. show that its the DD_RUM offering rather than just DD?

THis is just so folks start differentiating between DD rum and infra monitoring

Detect Sessionstack

Detect current Sentry SDK version being used as well as the latest version

• i.e. user may be using a version of the Javascript Sentry SDK that is really old, where performance doesn't even exist as an option
• Also include the latest version of the SDK, so that we know how big the gap is between the latest and what they're on
• credit to Simon for this idea

Instrument Sentry on sniffer to detect when sniffer errors

• We don't know how often the sniffer might be erroring, so instrument Sentry to give us an idea

Differentiate whether Sentry was detected for performance or not

Currently we just know whether Sentry was detected. Here we can detect whether it was used for errors only or both errors+perf.

@cstavitsky has been working on this: #8

Detect hostname + projId + sampleRate(s) when installed via CDN

#17 (comment)

Inconsistently detects Sentry on Unreal

Possible bug: flaky Sentry detection on https://unrealengine.com/id/login?response_type=code&redirect_uri=&client_id=3adb22b897e24666971f9a273b1c15e8, but two others do not.

__SENTRY__ is present on that page, so we should see it

However, we don't, sometimes?

But we also do sometimes:

• @ndmanvar was able to see it
• @cstavitsky was able to see it once, but not several other times upon reloading the page
• Richard was not able to see it

Goal would be to figure out why this is flaky.

[lower priority] __SENTRY__ detected, but details not detected

I don't know that this is possible: this is all we see when we check for SENTRY . There doesn’t seem to be any metadata that we can dig into to find out from the SDK perspective that I’m aware of. However, opening this issue in case it ends up being something we can figure out

[priority] Detect Sample Rates for errors and transactions

• requires performance to be detected

• i.e. detect super low sample rate, like 4

• applies only to hardcoded sample rate

capture AppDynamics - ADRUM

• Add AppDynamics to list of sniffed observability tools

Neil:

window.ADRUM for AppDynamics

Improve Sentry instrumentation

What we currently do, what I tried:

• installed Sentry using npm

• configured Sentry per normal JS instructions, initializing it in content.js

• received an error message: Uncaught SyntaxError: Cannot use import statement outside a module (at content.js:11:1)

• in package.json, added a top-level key "type": "module" (but this did not fix the issue as stackoverflow suggested). More stackoverflowing led to more dead ends 😕

• Another resource I looked into: adding sentry to chrome extension — this was not exactly needed since technically content.js does not run as a service worker — it gets appended to the DOM using injectScript

• I also tried injecting the sentry script itself, re-using the injectScript function but passing the src as the CDN sentry link. But when I do that, then try to Sentry.init I get: Uncaught ReferenceError: Sentry is not defined.

@ndmanvar 's idea for improvement:

random idea: if there is an error (with content.js), store the error in localstorage, and then have popup.js read off of that and send up (via Sentry.captureException / captureMessage) ? (edited)
^ i.e. wrap all of content.js essentialy in a try/catch, and then do the above in catch?

Increment release version (from .2 to .3)

[build/release]: Create release with dist artifact for download

Currently including dist as code in repo
Create script for creating release + attaching dist. Update readme accordingly as well

When DD: DD_RUM and/or DD_LOGS? (what datadog products are they using?)

• Currently we just detect the presence of DD.

Show 'Datadog RUM', rather than just 'datadog'

Detect sentry session replay, along with sample rates

Basically the same as we have for perf, but for session-replay

Detect tracesSampler

Rotate pictures of Santo

Neil to supply pictures, let add a few more and it randomly selects a picture. we can add pictures of other pets also (:

Detect SPLUNK RUM

I haven't figured out how to detect it. I don't see any populated variables re. splunk on the window/global

[low-priority]: Does not detect Raven installed via NPM

Detect FullStory

Sentry details (project Id, sdk) not showing for some websites even when data should be available

I.e. the project id data should be accessible

DD RUM not detected in at least one case where it is present

DD RUM is clearly present, but the sniffer does not detect it.

Example: https://www.warbyparker.com/asap-nast

Transaction sampling shows at impossible numbers

Transaction sampling shows at 1000%

[priority] Detect hostname of DSN

• If Sentry is used, detect the hostname of the DSN. Are they sending to sentry.io or some other domain? This can help distinguish self-serve vs. SaaS customers.
