In line with Slack’s documentation on message templates that can be sent to a webhook, I’ve created the following JSON template: Incoming webhooks are an easy way to simply send formatted messages to Slack channels in cases where you don’t need all the bells and whistles of the Slack API. To do something like this, you need to first go on Slack and create an app to get an Incoming Webhook. This way I can stay on top of stuff that may have failed or didn’t run on time, and mitigate issues before they blow up without my knowing for a few days. Enter Slack with their Messaging API, which I have used to set up a small reusable Python class that I can integrate in to all my apps to send messages on how scheduled runs went. Now, we have extensive logging going out from these applications to an ELK stack, but I like to have something I can look at on my phone to see whether a job ran on time or if it errored out. Most of these are Python applications are doing transformations on data, running machine learning models on batches of data as well as other activities that run on a schedule. I have a lot of automated jobs running as part of my day-to-day operational activities. The code for this article can be found here.
