Did Your Customer Tell You First the Last Time You Had an Outage?

If they did, you have a monitoring problem.

How do you know if the SaaS product you are delivering to customers is broken when the whole thing lives in the cloud? In the physical world, broken things announce themselves. Take a car. It does not start, it runs rough, it smells funny, or something is leaking. There are a dozen ways a car tells you something is wrong before it leaves you stranded on the side of the road.

Software does not work that way. There is no warning light, no strange noise, no puddle on the garage floor. Your workload can be spread across dozens of services and containers, and a failure in one of them might not surface for hours. Or it surfaces immediately for your customers while your team is still in the dark. Worse, you may have built redundancies that are doing exactly what they were designed to do, keeping the service running while quietly masking the fact that something already failed. Your product looks fine from the outside. Inside it is running on one engine instead of two.

This is why you cannot run a SaaS business without monitoring. Problems need to surface so they can be fixed before a customer notices. But effective monitoring is harder than it sounds. To do it right, three things need to be true: you are watching the right metrics, alerts are going to someone who can act on them, and every alert that fires is actually actionable.

Finding the Right Metrics

Figuring out what to monitor is often called the hardest part, but it is really just the part that never stops changing. Start with the basics. Is the service responding, is disk space healthy, are the critical processes running? That gets you off the ground.

Where it gets interesting is everything nobody thought to monitor until something broke.

The best monitors usually come out of outages. When something goes down, a postmortem should always follow. Not to assign blame, but to answer three questions: what was the root cause, can it be fixed permanently, and what would have told us this was coming before it became an outage? That last question is where monitoring pays off. Sometimes the monitor is temporary while a fix is being built. Sometimes it becomes a permanent early warning system for a known weak point. Either way, if you walk out of a postmortem without adding or adjusting a monitor, you missed the most valuable part of the exercise.

Your monitoring setup should never be considered finished. It should grow every time something fails and your team learns something new.

Alerts Need to Go to the Right Person

Once you have thresholds in place, the next question is who receives the alert. For early stage SaaS companies where one or two engineers wear every hat, this is straightforward. But as you scale, it matters more.

The person receiving an alert should be the one with both the access and the context to do something about it. A low disk space alert on a database server is a good example. The person managing the server infrastructure can make the disk bigger or delete files, but they may not know which files are safe to remove without taking down the service. That requires someone who understands what lives in that database. Resolving it cleanly means both people are involved, which means the alert needs to reach both of them, or there needs to be a clear escalation path between them.

In a small SaaS team with no dedicated infrastructure person, this is often where things fall apart. Alerts go to one developer's inbox, that developer is heads down on a feature, and the alert sits unread for three hours while customers are filing support tickets.

Every Alert Must Be Actionable

This is where most monitoring setups quietly fail.

An alert is only useful if there is something concrete to do when it arrives. I have seen too many setups where someone configured a CPU alert at 75% for five minutes and applied it to every server without thinking through what normal looks like for each one. An ETL process that runs for an hour every morning and pegs the CPU at 90% the entire time is not a problem. It is doing its job. But if that same server fires a CPU alert every single morning, the engineer starts to ignore it. They learn that server always does that. And then one day the CPU spikes because something is actually wrong, the alert fires the same as always, and nobody looks at it until a customer calls.

Alert fatigue is real and it kills the value of your entire monitoring setup. If an alert does not require an action, it should not exist. Every threshold should be reviewed regularly to make sure it still reflects what actually matters, not what someone set up two years ago and forgot about.

Monitoring Is Never Done

The best thing about a monitoring setup is that nothing is permanent. Thresholds can be adjusted, monitors can be added or retired, and alert routing can be changed as your team grows. It should be a living system that gets smarter every time something breaks.

For a SaaS business without a dedicated infrastructure team, that evolution does not happen on its own. It requires someone who treats monitoring as a discipline, not a checkbox. If your current setup is a handful of uptime checks and a Slack channel that nobody watches after 6pm, you are one bad deployment away from finding out about your outage from a customer review.

If you want to know what your monitoring setup should actually look like for where your business is today, Nixpar offers a free cloud infrastructure assessment. We will look at what you have, identify the gaps, and tell you what it would take to get ahead of the next outage instead of reacting to it. Schedule yours here: https://www.nixpar.com/contact
