It walks through how a developer solved this by exporting Crashlytics data to BigQuery and using a Google Data Studio template to filter crashes by custom log messages, without needing to learn SQL. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I search Crashlytics custom logs without writing SQL? Export Crashlytics crash data to BigQuery, then connect it to a Google Data Studio report using Firebase's provided template. Add an Advanced Filter to a report page, then set its control field to logs.message to search custom log events within crash data. The same approach works for other fields like analytics breadcrumbs by changing the control field. _Developers wiring up crash analytics workflows follow tool comparisons and guides like this on daily.dev._ --- Tags: [#mobile](https://daily.dev/tags/mobile), [#firebase](https://daily.dev/tags/firebase), [#google-bigquery](https://daily.dev/tags/google-bigquery) [View this post on daily.dev](https://daily.dev/posts/crashlytics-and-the-great-crash-detective-comic-avzyygwco) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Crashlytics and the Great Crash Detective Comic","url":"https://daily.dev/posts/crashlytics-and-the-great-crash-detective-comic-avzyygwco","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/crashlytics-and-the-great-crash-detective-comic-avzyygwco"},"datePublished":"2026-08-23T12:19:40.975Z","dateModified":"2026-08-23T12:28:21.131Z","description":"A lighthearted post introduces Firebase's first comic, 'The Great Crash Detective,' inspired by a real customer interview about searching custom logs in crash...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7ed721de96163685d26ab7e314be3ebc?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Firebase","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Firebase","logo":"https://media.daily.dev/image/upload/s--i395oqZH--/f_auto,q_auto/v1787487448/logos/firebase-blog?_a=BAMAMicg0","url":"https://daily.dev/sources/firebase-blog"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/crashlytics-and-the-great-crash-detective-comic-avzyygwco","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"mobile,firebase,google-bigquery","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Firebase","item":"https://daily.dev/sources/firebase-blog"},{"@type":"ListItem","position":3,"name":"Crashlytics and the Great Crash Detective Comic"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/crashlytics-and-the-great-crash-detective-comic-avzyygwco#faq","mainEntity":[{"@type":"Question","name":"How can I search Crashlytics custom logs without writing SQL?","acceptedAnswer":{"@type":"Answer","text":"Export Crashlytics crash data to BigQuery, then connect it to a Google Data Studio report using Firebase's provided template.
