Heroku provides many instrumentations for your app out of the box through our new Heroku developer experience.
We have open-sourced some of the tools used to instrument Heroku apps, but today’s focus will be on instruments, a Go library that allows you to collect metrics over discrete time intervals.

A quick glance at most any phone shows the importance and urgency – for businesses of all kinds – of creating mobile customer apps. Our everyday activities – finding a ride, ordering a meal or turning on a light are increasingly mobile experiences.
But delivering a great omnichannel experience to customers requires more than just the work of the application developer. The larger organization is involved in following up with prospects, fielding service inquiries, …

One of the challenges when starting a mobile app project is deciding what technology stack to use. Should the client app use iOS or Android native, mobile web, or a hybrid? Do the backend in Node, Ruby, or Java? Or skip the backend and use an Mobile Backend-as-a-Service?
To help avoid needing to answer all those on your own we are open sourcing the Heroku Mobile Template. This app provides a full-stack starting point for creating new hybrid mobile apps and deploying them to Heroku.

Celery is by far the most popular library in Python for distributing asynchronous work using a task queue. If you’re building a Python web app, chances are you already use it to send email, perform API integrations, etc. Many people choose Redis as their message broker of choice because it’s dead simple to set up: provision a Redis add-on, use its environment variable as your BROKER_URL, and you’re done. But the simplicity of Redis comes at a cost. Redis does not currently support SSL, and it doesn’t seem like that’s going to change any time soon. Because Heroku add-ons communicate over the public web, that means the contents of Celery jobs are traveling unencrypted between dynos and Redis.

Many of Heroku's internal components make heavy use of logfmt to log information about what's going on in production. The format is hugely valuable in that it allows us to retroactively analyze what happened during any arbitrary request to our components, query our log traces in very flexible ways, and combined with Splunk, easily generate arbitrary metrics on historical data. It's unquestionably been an invaluable tool for fixing countless bugs, tracking down the root cause of many production incidents, and assessing usage in ways that would have been difficult otherwise.

Retrospectives are a valuable tool for software engineering teams. Heroku consistently uses retrospectives to review operational incidents, root cause problems, and generate remediation tasks to improve our systems. Increasingly we use retrospectives for another purpose: to improve teamwork and interactions on projects. Here we intentionally avoid technical discussions and focus on the emotional and human aspects of work, with the goal of creating positive insights into how to improve as a team.

In May we released the first version of Heroku Connect, a service that makes it easy to build Heroku apps that share data with your Salesforce deployment.
Today we released our first major update to the service, bringing new speed and scale enhancements to all Heroku Connect users. Together, these enhancements lower latency on Heroku Connect synchronization, provide developers with more granular controls and improve insight into their Force.com API utilization.

Heroku Connect is a service offered by Heroku which performs 2-way data synchronization between Salesforce and a Heroku Postgres database.
When we first built Heroku Connect, we decided to use polling to determine when data had changed on either side. Polling isn’t pretty, but its simple and reliable, and those are “top line” features for Heroku Connect. But polling incurs two significant costs: high latency and wasted resources. The more you poll the more you waste API calls and database queries checking when there are no data changes. But if you lengthen your polling interval then you grow the latency for the data synchronization.
