The moment it happens

Get Slack alerts for full volumes and high CPU or memory

When Railway flags a volume near capacity or a CPU or memory alert, the details are posted to your ops channel.

Send this to your assistant

Create a ClickRuntime automation: give me a webhook link for Railway and post any volume usage or CPU and RAM alert to #infra in Slack, with the project and service.

Paste it into your assistant. It tells you what it will send or change before it runs live.

Why use it

Why teams use this automation

A Railway volume that fills up silently takes a database down, and an application that creeps up in memory eventually gets killed. Both situations give hours or days of warning in the metrics, but metrics are only useful if someone is looking at the graph before it reaches the limit. Most people see it for the first time after the outage.

When Railway's usage alert fires, such as a volume nearing capacity or CPU and memory staying high, ClickRuntime receives it, formats the details with the service, the resource and the level, and posts it to your channel. You hear about the pressure while there is still headroom to resize a volume or look into a leak.

It is especially useful for stateful services like Postgres, Redis or file uploads that live on a volume.

What you get out of it

Disks are resized before they fill
A volume at 85 percent can be expanded in minutes. A volume at 100 percent often means a crashed database, corrupted writes and a long recovery, so the early warning avoids all of that.
Memory leaks are found by symptoms
Slowly rising memory is the classic sign of a leak. The alert gives you the trend early, so you can restart or fix the leak on your schedule instead of during a customer-facing outage.
Scaling decisions become informed
Repeated CPU alerts on one service show where you need more resources or better code. You spend on capacity for the service that needs it, not on a blanket upgrade.
Database health is protected
Stateful services are the most costly to lose. Hearing about storage pressure on Postgres or Redis protects data you cannot easily recreate, and spares you from restoring from backups. That makes a warning cheap insurance.
A shared view for the whole team
Posting in a channel means anyone on call can see the pressure and respond. It is no longer a graph that only one person checks, and handover between teammates is simpler.

How it works

What happens, step by step

When Railway raises an alert for your project, such as a volume nearly full or high CPU or memory, it tells ClickRuntime straight away.
The automation turns the alert into a short, readable message with the project, service and what's wrong.
It's posted to #infra, like "Railway volume alert in Northwind shop / postgres: volume is 85% full".

Build your own

Need it to work differently?

This template is a starting point. Copy the prompt and change it, or describe a different automation from scratch, with your own conditions, more apps or an AI step. Your assistant writes it, tests it and runs it on ClickRuntime.

Your own rules
Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.
Any number of apps
One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.
AI where it helps
Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.
On a schedule or on each event
Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

Changes you can ask for

Act only on the items that match your own rules, and skip the rest
Add an AI step, for example to summarize, sort or draft a reply
Add another app, for example also send it to Slack
Combine it with other Railway steps into one automation

Under the hood

The code that runs this automation

This is the Python script that runs each time the automation starts. Your AI assistant writes it for you when you send the prompt, and you allow each step in your assistant. To change how the automation works, describe the change to your assistant and it updates the script for you. For every function it can use, see the script reference.

FAQ

Common questions

Which thresholds does Railway alert on?

Railway lets you set usage alerts for resources like CPU, memory and volume storage in the project settings. The alert fires when your chosen threshold is crossed. ClickRuntime handles the message that arrives, so the thresholds themselves are configured in Railway.

Will I get repeated alerts while usage stays high?

That depends on how Railway sends them, since it controls when an alert fires. If it repeats, the messages can be limited to one per service per hour in ClickRuntime so a persistently high service does not flood the channel.

Does it work for services on the Hobby plan?

Webhooks and usage alerts are available according to your Railway plan. If your plan lets you create webhooks on a project, the alert can be delivered here. Check Railway's current plan features for what is available on yours.

What permissions does it need?

webhook setup. Nothing else in your accounts is used.

Does it need AI?

No. It runs without AI, so it doesn't use your plan's AI allowance.

How many runs does it use?

One run for each event the app sends.

Can I change how it works?

Yes. Describe the change to your AI assistant, for example a different schedule, channel or filter. It updates the automation, tests it and tells you what changed.
