Connect Chamber to your Slack workspace and never miss a beat — get real-time workload notifications, capacity alerts, AI-powered answers, and scheduled utilization reports delivered straight to the channels your team already uses.

​
Why Slack?

  • Instant awareness — Know the moment a workload fails, gets preempted, or completes without watching the dashboard
  • Smart channel routing — Route different notification types to different channels so the right people see the right alerts
  • Personal control — Every team member decides what they get and how (channel post or DM)
  • AI chatbot — Ask Chamber questions in plain English right from Slack and get answers about workloads, GPUs, capacity, and costs
  • Automated reports — Daily or weekly utilization digests posted to any channel, on your schedule

​
Connect Your Workspace

Connecting Slack requires Org Admin permissions.

Open Integrations

Navigate to Settings → Integrations in the Chamber dashboard.
2

Click Connect Slack

Click the Connect Slack button. You’ll be redirected to Slack’s authorization page.
3

Authorize Chamber

Review the requested permissions and click Allow. Chamber needs access to read channels, post messages, and look up users.
4

Pick a default channel for notifications. You can override this per notification category later.
5

Verify the Connection

Click Send Test Message to confirm everything works. You should see a test notification in your selected channel.

​
Notification Types

Org Admins control which notification types are active at the organization level. Here’s everything Chamber can alert you about.

Clawback OpportunitiesFlags reclaimable underutilized reserved capacityOff

​
Reports

Weekly Cost ReportWeekly cost breakdown with trendsOff

​
Channel Routing

By default, all notifications go to the channel you selected during setup. Override this per category to make sure alerts reach the right audience. Available categories:
  • Workload Notifications — Workload events (started, completed, failed, preempted, queue changes)
  • Capacity Alerts — Utilization warnings, reservation expirations, pool capacity, clawback
  • Reports — Daily and weekly scheduled digests
1

Go to Slack settings

Navigate to Settings → Integrations → Slack → Channel Overrides.
2

Set a channel override

Select a notification category and pick the target channel from the dropdown. Chamber lists all public and private channels it has access to.
3

Remove an override

Click the remove button next to any override to revert that category back to the default channel.
A common setup: route Capacity Alerts to #infra-alerts for platform engineers, and Workload Notifications to #ml-workloads for ML engineers.

​
User Linking

Chamber automatically maps your team members to Slack users by matching email addresses. This powers @mention notifications so individuals get pinged directly when their workloads complete or fail. To trigger a sync:
  1. Go to Settings → Integrations → Slack
  2. Click Sync Users
  3. Chamber matches emails between your Chamber organization and Slack workspace
After syncing, you’ll see a count of linked users. Anyone without a matching email can be linked manually by an admin.

​
Personal Notification Preferences

Every team member can customize their own Slack notifications without affecting anyone else. Navigate to Settings → Integrations → Slack → My Preferences to configure:
SettingOptionsDefault
EnabledOn / OffOn
Delivery MethodChannel post / Direct messageChannel
Mention MeInclude @mention in channel postsOn
Workload FailedNotify on failuresOn
Workload PreemptedNotify on preemptionsOn
Workload StartedNotify on startsOff
Workload CompletedNotify on completionsOff
Workload SubmittedNotify on submissionsOff
Workload QueuedNotify on queue entryOff
Queue Position ChangesNotify when position changesOff
Personal preferences only apply to your own workloads. Org-level notifications like capacity alerts and reports are controlled by admins.

​
AI Chatbot

The Chamber Slack chatbot lets your team talk to Chamber directly from Slack. Ask questions in natural language and get instant answers about workloads, utilization, capacity, costs, and more.
The AI chatbot must be enabled by an Org Admin. Go to Settings → Integrations → Slack and toggle AI Chat on.

​
How to Use

  • Mention the app in any channel: @Chamber what's the GPU utilization for the training team?
  • Send a DM to the Chamber app for private queries
  • Reply in threads to continue a conversation with full context

​
Example Queries

  • “What workloads are currently running?”
  • “Show me GPU utilization for the last 24 hours”
  • “Which team has the highest GPU spend this week?”
  • “What’s the queue depth for the research cluster?”
  • “Why did workload train-resnet-42 fail?”

​
What the Chatbot Can Do

  • Look up workload status, history, and failure details
  • Report on GPU utilization and capacity across clusters
  • Surface team and user activity
  • Provide cost and spend breakdowns
  • Draft and send emails on your behalf (with preview before sending)
  • Link you directly to the relevant dashboard page
Thread replies maintain full conversation context — ask follow-ups like “and what about last week?” without repeating yourself.
