Introduction​

Maintaining transparent communication about service availability is crucial for businesses of all sizes. Status pages are an important part of your communication strategy during times of outages and maintenance events.

You can choose to go with a fully managed status page provider, or host an open-source one yourself.

Open source status page providers offer a cost-effective and customizable solution. However, then can come with their own drawbacks. This guide explores open source status page providers in 2024 to help you choose the right tool for your needs.

List of Open Source Status Page Providers​

1. Cachet​

Cachet is a popular open source status page system built with PHP and Laravel. It offers a clean, minimalist design and a robust feature set.

Introduction​

Downtime is inevitable but what sets successful businesses apart is how they handle it. A key part of incident management is incident communication with both internal and external stakeholders. A status page is a crucial tool for maintaining clear communication with users during outages or service interruptions. There are numerous status page providers available with different features. This article will guide you through best practices for selecting a provider that suits your needs.

The Importance of a Status Page​

An internal status page provider your colleagues and stakeholders in your organization to get a snapshot of of the current status. It can help reduce unnecessary back and forth between teams, and help people to prioritize their work better. It also creates internal transparency and trust between teams.

An external status page is crucial if you say you are committed to open communication with your end users or customers. Whether you are B2B or B2C, a public status page would be the first thing people would check if they face issues. Being open about incidents and your efforts to mitigate them build user trust. They can also decrease support ticket volume during incidents.

You can choose an open source status page provider, or one that is managed. This guide focuses on the factors to look at while evaluating managed providers.

Key Factors to Consider When Choosing a Status Page Provider​

1. Reliability​

Your status page needs to be accessible especially when your main services are down. Your provider should be able to guarantee a reasonable amount of

• Uptime SLA
• Globally distributed infrastructure for high availabilty
• Redundant systems to ensure failover and availability
• Scalability to handle increased traffic during major incidents

Introduction​

Incident updates on the public status pages of your cloud providers are often the first indication that they might have an outage. Providers also post updates about upcoming and ongoing maintenance on their status pages. Thus, monitoring your cloud status pages becomes crucial to your business operations. This article will guide you through the process of effectively monitoring such status pages.

Identify Your Cloud Providers​

Work with your Dev/Ops/SRE and IT teams to come up with a comprehensive list of your cloud providers. Any service that is not managed by your teams is by definition a cloud service. Although we focus on Cloud providers - i.e. providers that let you deploy your services on their infrastructure - this article is equally applicable to any of your external SaaS vendors.

Introduction​

Modern businesses depend heavily on Software as a Service (SaaS). Almost all aspects of business operations - accounting, HR, payroll, marketing, IT, sales, support - depend on one or more SaaS applications. SaaS is not limited to being used by software development teams. Given this dependency on SaaS applications, their uptime becomes tightly tied to a business's uptime. Any SaaS downtime can affect both a business's daily operations as well as the user experience.

How to check if a SaaS is experiencing downtime? Follow the steps below:

1. Visit the SaaS Provider's Status Page
2. Use External Monitoring Services
3. Check Social Media
4. Run Manual Tests
5. Incident Communication

8. Popular SaaS Service Statuses

Visit the SaaS Provider's Status Page​

The SaaS provider's status page will have first-hand information about ongoing issues.

Introduction​

A recent question in an SRE forum triggered this train of thought.

How do I deal with alerts that are triggered by internal patching/release activities but don't actually cause a downtime? If we react to these alerts we might not have time to react to actual alerts that are affecting customers.

I've paraphrased the question to reflect its essence. There is plenty to unravel here.

My first reaction to this question was that the SRE who posted this is in a difficult place with systemic issues.

Systemic Issues​

Without knowing more about the org and their alerting policies, let's look at what we can dig out based on this question alone

A few weeks ago we released a feature on IncidentHub which gives you a historical view of your monitored services' availability.

Why Was This Needed?​

On the dashboard where you can add services and channels, there is an overview panel that shows total incidents in the last 24 hours. You can get into a more detailed view by clicking on the button next to it. This opens up a popup where you can see active and resolved incidents - in the last 24 hours - and filter them by service.

This panel is good enough for a quick view on what's affecting your dependent services. However, sometimes there is a need to look back further. This is what the Availability page gives you - an overview of service health over the last 30 days.

Let's look at a few examples:

Chances are, most of your third-party cloud and SaaS dependencies are globally distributed and have many regions of operation. Chances are, your applications use a subset of a cloud or SaaS service. If you are monitoring such a service, why should you receive alerts for all regions or every single component in the service?

E.g. if you use Digital Ocean, you might be using Kubernetes in their US locations (NYC and SFO). You would want to know only when there is an outage in one of these locations. Digital Ocean's status page gives you the option to subscribe to outages across the board - it’s all or nothing. This is the case with most services with a few exceptions.

Choosing Specific Components to Monitor​

You can now choose which components/regions you wish to monitor in IncidentHub. Let us continue with our Digital Ocean example.

You can choose to monitor all components:

Introduction​

PagerDuty's Events API V2 lets you push events from your monitoring systems to PagerDuty. You can push such events when there is a triggered, updated, or resolved incident.

Incident Lifecycle​

The lifecycle of an incident will typically go through these states

You can either use any of the PagerDuty client SDKs to send events, or roll out your own.

Why should you monitor your third-party Cloud and SaaS vendors if you are in SRE/Ops?

As part of an SRE team, your primary responsibility is ensuring the reliability of your applications. What makes you responsible for monitoring services that you don't even manage? Third-party services are just like yours - with SLAs. And outages happen, affecting you as well as many others who depend on them.

It's a no-brainer that you should know when such outages happen to be on top of things if/when it affects your running applications.

Most of your third party dependencies will have a public status page or a Twitter account where they publish updates on their outages. Here are some seemingly easy ways to monitor these pages

• Subscribe to the RSS feed of these pages
• Follow the Twitter account
• Sign up for Slack, Email, SMS notifications on the status page itself if the page supports these

How many monitoring tools do you have?

Chances are at least 2-3. One tool usually does not cover all cases, and it’s usually a combination of self-managed and managed tools. Self-managed gives you more control over custom configurations and cost. Managed ones take away the headache of running it yourself.

Prometheus is the de-facto standard for monitoring these days if you have a modern application stack and you want to manage your own monitoring. It is metrics-based, i.e., it uses metrics as the source of data from all the monitored systems. There are ready-made exporters for almost all popular infrastructure components. You can send your application and business metrics to Prometheus too with OpenTelemetry exporters.

This model does not work for all aspects of your service. E.g. If you want to monitor external properties like your website, or use synthetic monitoring to check your customer-facing APIs from global locations, you could use something like Pingdom or UptimeRobot. This becomes another source of data about your service's uptime.
