Slack

The Sumo Logic App for Slack provides monitoring and data analytics for Slack users, channels, access logs for workspaces with free, standard, plus, and enterprise plans. The app is focused on public channels only.

Slack is a cloud-based set of software tools and online services that provide for secure collaboration across teams, departments, offices, and countries.

Log Types

Slack logs are in JSON format. The Slack App utilizes the following log types:

User logs
Public channel logs
Public message logs
Access logs
Audit logs

Sumo Logic’s Slack collector enhances the logs by adding a few metadata fields so the raw logs from Slack APIs might differ in format. The availability of all types of logs is determined by the slack plans.

Log Type	Free plan	Standard plan	Plus plan	Enterprise plan
User logs	✓	✓	✓	✓
Public Channel logs	✓	✓	✓	✓
Public Message logs	✓	✓	✓	✓
Access logs		✓	✓	✓
Audit logs				✓

Collect logs for the Slack App

This legacy solution to pull logs from Slack to Sumo Logic has been replaced with a dedicated Cloud-to-Cloud Integration Framework. We recommend customers use the below Slack Cloud-to-Cloud source instead of the legacy Python collection method.

Setup and Configuration Overview

The Slack source can collect data from Slack's Web API and Audit API. The Web API is used to collect standard channel, user, and message information from a specific workspace. The Audit API is used to collect security audit events across the entire account including all workspaces, but it requires a Slack Enterprise Grid license. Each API collects different information; collect from both if you have a Slack Enterprise Grid license.

We recommend creating a Slack App for each Slack Workspace you want to monitor. This requires a Sumo Logic Slack C2C per Slack Workspace. If you have a Slack Enterprise Grid account, you can create an additional Slack app, install it on the Enterprise Grid instead of a Workspace and create another Sumo Logic C2C to monitor your Enterprise Grid audit logs from the Audit API.

Process overview

Create the Slack App with the correct permissions.
Install the Slack app on a specific workspace to monitor Web API logs or install the app on the Enterprise Grid to monitor Audit API logs.
Install the Sumo Logic Slack C2C using your credentials from the installed Slack App.

Create Slack App with Permissions

Navigate to the Slack Apps page.
Click Create New App.
Select From scratch if asked how you would like to configure your Slack app.
Provide a App Name for your Slack App and select the Workspace you want to monitor and install the Slack App in. The Sumo Logic collector will monitor logs from your workspace you select here. If you want to install the app on the Enterprise Grid instead of a workspace to monitor the Audit API logs, select a workspace for now, and you will see instructions later for migrating it.
Click Create App.
You are now presented with the basic information about your Slack app. Click Permissions in the Add features and functionality section.
Scroll down to the Scopes section add multiple User Token Scopes depending on your Slack account type.

Use the table below to reference the required scope permissions you need to add depending on the Slack API you want to collect along with your Slack account type:

Slack API	Slack Account Type	Required Scopes
Web API	Free Plan	admin, team:read, users:read, users:read.email, channels:read, channels:history
Web API	Pro	admin, team:read, users:read, users:read.email, channels:read, channels:history
Web API	Business+	admin, team:read, users:read, users:read.email, channels:read, channels:history
Web API	Enterprise Grid Plan	admin, team:read, users:read, users:read.email, channels:read, channels:history
Audit API	Enterprise Grid Plan	auditlogs:read

Install the Slack App on a Workspace for Web API Logs

Only follow these steps if you are installing a Slack App on a specific workspace to monitor Web API logs. Please ensure you have followed the prior steps for creating the Slack app with the appropriate permissions before continuing to this section.

On the app settings page, click Install App and the Install to Workspace button.
Allow your new Slack App to monitor your workspace.
Save the generated access token. This will be used by the Sumo Logic configuration for access.

Install the Slack App on the Enterprise Grid for Audit API Logs

Only follow these steps if you are installing a Slack App on the Enterprise to monitor Audit API logs. Make sure you have followed the prior steps for creating the Slack app with the appropriate permissions before continuing to this section. A Slack Enterprise Grid account is required.

On the app settings page, click OAuth & Permissions.
Scroll down to Redirect URLs. Add a new redirect URL as https://localhost and click Save URLs.
Go to Manage Distribution > Share Your App with Other Workspaces
Open the Remove Hard Coded Information section on the same page and check the I’ve reviewed and removed any hard-coded information checkbox. Click the Activate Public Distribution button.
Copy the shareable link and ensure the permissions are correct from the prior table.
Open a new tab in your browser, paste the URL and press Enter.
Select the dropdown menu in the upper right corner and choose the correct organization.
Click Allow.
Ignore the error message and copy the Code in the URL field, as shown in the following example.
Get the client ID and client secret from the Basic information of your Slack app. Replace the <CODE>, <CLIENT_ID> and <CLIENT_SECRET> variables in the following URL.
https://slack.com/api/oauth.v2.access?code=<CODE>&client_id=<CLIENT_ID>&client_secret=<CLIENT_SECRET>
Open a new browser tab and paste the URL from the previous step into the URL field, then press Enter.
From the response, save the token value from the field access_token as it will be used for the Sumo source.

{
  "ok": true,
  "access_token": "xoxp-1236544616-Example-Access-Token5bf71298dad60d941f2a44b371",
  "scope": "admin,identify,channels:history,groups:history,im:history,channels:read,team:read,users:read,users:read.email,auditlogs:read",
  "user_id": "WA7PQK3U5",
  "team_id": "EFSFVS",
  "enterprise_id": "EASFEF",
  "team_name": "Test Slack App"
}

Install and Configure the Sumo Logic Slack Cloud-to-Cloud

Add a new source on a Sumo Hosted Collector
Search for and select Slack for the source
Provide a name for the source
Select the Slack collection API you want to collect logs from (Web or Audit)
Paste your Slack App access token from the previous steps
