About SentryUptimeMonitoring

Sentry Uptime Monitoring is a feature of the Sentry platform that checks customer websites and APIs for availability.

Monitoring bots check uptime, performance and page changes on behalf of a site owner or a third party. Allow the services you run yourself and exclude them from analytics so they do not inflate page views.

SentryUptimeMonitoring user agent

SentryUptimeMonitoring identifies itself with this user agent string:

  • SentryUptimeBot/1.0 (+http://docs.sentry.io/product/alerts/uptime-monitoring/)

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block SentryUptimeMonitoring in robots.txt

We have not confirmed whether SentryUptimeMonitoring follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Block SentryUptimeMonitoring from the whole site

User-agent: SentryUptimeBot
Disallow: /

Block SentryUptimeMonitoring from some folders

User-agent: SentryUptimeBot
Disallow: /private/
Disallow: /search

Allow SentryUptimeMonitoring only on some folders

User-agent: SentryUptimeBot
Allow: /blog/
Disallow: /

Allow SentryUptimeMonitoring and block other crawlers

User-agent: SentryUptimeBot
Allow: /

User-agent: *
Disallow: /

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: SentryUptimeBot group, SentryUptimeMonitoring ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take SentryUptimeBot from SentryUptimeMonitoring's user agent; check Sentry Uptime Bot's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. SentryUptimeMonitoring may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that SentryUptimeMonitoring follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send SentryUptimeMonitoring's user agent, and a scraper using it is not bound by Sentry Uptime Bot's robots.txt policy. Only checking the source network tells a real SentryUptimeMonitoring from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.

How do I block SentryUptimeMonitoring?

Is robots.txt enough to block SentryUptimeMonitoring?

No. robots.txt is voluntary, so SentryUptimeMonitoring may not follow it, and anyone can send SentryUptimeMonitoring's user agent, so a fake SentryUptimeMonitoring ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
