Tech Tips
Check Your Logs When Encountering Issues
If you are having performance issues or are getting errors, you can save a lot of time and hassle by first checking your logs. Logs are a stream of time-ordered events aggregated from the output streams of all your app’s running processes, system components, and backing services. Heroku’s Logplex routes log streams from all of these diverse sources into a single channel, providing the foundation for truly comprehensive logging.
You can check your logs by typing the following command into the CLI:
$ heroku logs
Tailing your live logs while you are using your app can be a very powerful troubleshooting technique:
$ heroku logs --tail
You can even filter down to a specify type of process:
$ heroku logs --tail --process app
For more information about logging, please visit the Heroku Dev Center.
Add-On Tech Tips
Understanding the Capabilities of Neo4j
Neo4j is a powerful open source graph database,  storing data in the nodes and relationships of a graph. Currently, it is available in beta through our add-ons catalog. Neo4j provides accessibility to NoSQL with the addition of a new query language code-named “Cypher". Since Cypher's constructs are based on English prose and neat iconography, it is rather self-explanatory to anyone from the most advanced developers to business professionals.
In this video tutorial, Neo4j Founder and VP of Product Peter Neubauer shows you how Neo4j and Heroku make querying big data simple. Learn how to set up an app using Neo4j on Heroku, write a complex Cypher query to the database, and then plug returns into Google Spreadsheet graphs, all within ten minutes.
