Optimizing your website's health: A comprehensive guide to monitoring alerts

Optimizing your website's health: A comprehensive guide to monitoring alerts

January 3, 2024

Website downtime can significantly negatively impact businesses that rely on their online presence and connectivity. Without a website, companies can lose sales, damage their reputation, and frustrate customers trying to access information or services. That's why having an effective alert system for website and application monitoring is critical.

Types of alerts

There are two main types of alerts for monitoring website downtime:

Real-time alerts

Real-time alerts are triggered immediately when an issue is detected with your website. These allow you to get notified right away if your site goes down or becomes unresponsive. Real-time alerts are critical for quick incident response.

With real-time alerting, you'll get notifications pushed to you instantly via text, email, phone calls, Slack, etc. This enables your team to investigate and fix the problem ASAP before significantly impacting users. Speed is essential for minimizing downtime.

Real-time alerts are ideal for monitoring critical website infrastructure and performance metrics. For example, you'd want real-time alerts for your server status, website response time, error rates, and more. Any vital components that require immediate attention if they fail or degrade.

Scheduled alerts

Scheduled alerts are sent on a recurring timeframe that you specify, such as daily or weekly reports. These allow you to get summaries of your website metrics and uptime during that period.

Scheduled alerts are useful for spotting longer-term trends and getting extensive picture views of your site's health and traffic. You can configure what metrics and data to include in the scheduled email or report.

While scheduled alerts won't notify you immediately if your site goes down, they are valuable for ongoing monitoring and analytics. They help you spot inconsistencies, identify recurring issues, improve processes, and optimize website performance.

Combining real-time and scheduled alerts provides comprehensive monitoring coverage for your website's critical incident response and long-term trend analysis. Configure each to fit your use cases and needs best.

Monitoring tools

Monitoring tools are vital in website downtime alert systems by providing the core metrics that trigger alerts. There are three main types of monitoring tools:

Web monitoring services

Web monitoring services simulate visitors accessing a website from locations around the world. They check that web pages load properly and measure page load times. Popular options include Pingdom, Datadog Synthetics, and Uptime Robot.

Web monitoring helps catch common issues like server downtime, slow page loads, missing resources, and errors preventing access. It provides insight into real user experiences. Monitoring from global regions can detect localized outages. Frequent checks from multiple locations identify problems quickly.

Server monitoring

Server monitoring software tracks backend metrics like CPU usage, available memory and disk space, database connections, etc. Leading tools like Datadog, New Relic, and SolarWinds Server & Application Monitor provide deeper insight into application and infrastructure performance.

Server monitoring helps identify capacity limitations and bottlenecks that degrade site performance. Tracking usage over time facilitates planning for traffic growth. Performance metrics reveal problems that impact site availability and speed.

Synthetic monitoring

Synthetic monitoring simulates user transactions through automation scripts that interact with sites. It measures the availability, performance, and correctness of processes. Popular synthetic tools include Catchpoint, ThousandEyes, and Loader.io.

Synthetic monitoring verifies that end-to-end business processes work properly. Automated scripts can log in, search, and complete e-commerce purchases. Monitoring critical user journeys ensures customers can complete tasks on the website successfully.

Metrics to monitor

When setting up monitoring and alerts for website downtime, there are a few key metrics you'll want to keep an eye on:


Uptime refers to the percentage of time that a website is available and accessible to users. This is one of the most critical metrics, as any downtime will directly impact revenue and customer experience. Most alert systems will continuously check uptime and send notifications if the website becomes unreachable.

Response time

Response time is the time it takes for a webpage to load fully. Slow response times frustrate users and lead to bounces. Monitoring response time will let you know if pages are loading slowly. Alerts can be triggered if response times cross a certain threshold.


Sudden drops or spikes in website traffic can indicate technical issues. Monitoring traffic levels will allow you to correlate problems to changes in visitor volume. Alerts for abnormal traffic patterns can notify you of potential problems.


Tracking website errors like 404 pages and 500 errors lets you know when visitors encounter issues. Increases, especially 5xx server errors, point to backend technical problems. Alerts for error rate spikes can inform you of any emerging issues.

Setting up monitoring and alerts for these key metrics will notify you as soon as potential website downtime occurs or is imminent. This allows you to investigate and resolve the problems before significant impact quickly.

Alert triggers

Effective alert systems allow you to set customized triggers to fire alerts when certain thresholds are crossed, or events occur. Some of the most crucial website monitoring triggers to set up include:

Response time thresholds

Slow website response times are among the most common indicators of downtime or other issues. Set alerts to go off when response times cross set thresholds, such as when the average response time goes over 400ms or a certain percentile response time over 1s. Being notified quickly of rising response times allows you to troubleshoot and address problems before they lead to more serious outages.

Traffic drops

Sudden drops in traffic can signify a website outage or other significant issues preventing users from accessing the site. Configure alerts for percentage drops in traffic over specific timeframes, like a 50% traffic drop over 10 minutes. Traffic alerts should also have customized baselines set during normal usage hours for your site so legitimate traffic fluctuations don't trigger false alerts.

Error spikes

Spikes in website errors like 400-level client or 500-level server issues often precede more serious downtime. Set alerts to go off when key error metrics exceed their normal baselines by set percentages, like a 400% increase in 500 errors over 5 minutes. For the fastest response time, errors should be monitored across services like web servers, databases, networks, and APIs.

Setting the right triggers will enable your alert system to automatically detect downtime and performance issues so your team can respond rapidly and limit disruption. Adjust triggers as traffic patterns change to maintain an optimal balance of notification speed and false alerts.

Alert delivery methods

When your website or application experiences downtime or issues, having alerts delivered through multiple channels can ensure the right people are notified as quickly as possible. Here are some of the most common delivery methods for alerts:

Email alerts

Email is one of the most ubiquitous alert delivery methods. Email alerts can notify both individuals and groups about website downtime events. Most alerting systems allow you to customize who receives email alerts based on the severity of the issue. For example, you may want to send critical alerts to a comprehensive distribution list while only sending routine alerts to the dev ops team.

The benefit of email alerts is they don't require the recipient to have a specific application installed. The downside is that email can get buried or be slower than other delivery channels.

SMS alerts

SMS or text message alerts provide a fast way to notify individuals about website downtime, especially useful for those not sitting at a computer. SMS allows alerts to reach people wherever they are, and messages rarely go unnoticed, like email.

Most IT and web teams rely on SMS alerts for critical issues that require immediate attention. SMS alerts can be sent to a single user distribution group or via an automated calling tree to escalate notifications.

Push notifications

For users of mobile apps and browser extensions, push notifications provide real-time alert delivery. Push notifications pop up on a user's device without any action needed on their part.

Push notifications are great for teams monitoring websites remotely and wanting to get alerts even when they aren't logged into a dashboard. This could include developers, IT staff, and "on-call" incident responders.

Phone calls

An automated phone call is the most direct way to notify someone about an issue. Some monitoring tools will call designated people and send a pre-recorded message about the website problem detected.

Phone calls are handy for major outages where SMS or push notifications might be insufficient. They ensure that the alert recipients are aware of the issue. However, too many automated calls could be considered disruptive by the recipients.

Alert customization

One of the key benefits of a robust alert system is the ability to customize alerts based on your specific needs. Here are some of the ways alert customization can be leveraged:

Priority levels

Most systems allow you to set different priority levels for alerts. For example, you may want to classify an alert as a low, medium, or high priority. High-priority alerts may relate to the entire website being down, while low-priority alerts could be for minor issues that don't impact site performance. This lets your team quickly identify and respond to the most critical alerts.

Time of day

You can configure alerts to only be triggered during specific periods. For instance, you may not want to be woken up at 3 am for low-priority alerts. You can set alerts during sleeping hours to only be triggered if they are high priority.


Alerts can be customized only to reach the relevant recipients. High-priority alerts may go to the entire team, while lower-priority technical issues can be routed to just engineering leads. You can also configure rotations based on the time of day so that alerts are sent to the appropriate on-call engineer.

Re-Alert frequency

If an issue isn't resolved quickly, you can have the system continue sending alert notifications at customized intervals to ensure the problem gets attention. For instance, you may want to re-alert every 15 minutes for high-priority issues until they are resolved.

Delivery methods

Customize how alerts are delivered based on priority, recipient, or time of day. High-priority alerts may require a phone call or SMS, while lower-priority alerts can be sent via email or chatbot.

Integration with ticketing systems

Many alert systems can automatically open tickets in services like Jira or ZenDesk based on alert triggers. Custom workflows can be created to assign and prioritize these tickets appropriately.

By customizing your alerting to your specific environment and needs, you can optimize your team's response and avoid unnecessary notifications. The key is setting up the right configurations for different scenarios.


Integrating your monitoring and alerting system with other tools in your technology stack can enhance functionality and streamline workflows. Here are some common integrations to consider:

Incident management tools

Integrating your monitoring system with incident management software like PagerDuty, OpsGenie, or VictorOps allows for smooth hand-off of issues. Alerts can automatically create and escalate incidents based on severity. Teams can also leverage bidirectional integrations to acknowledge and resolve alerts directly from the incident record.

Chat platforms

Chat apps like Slack or Microsoft Teams enable alerts to be delivered via chatbot. This allows fast, streamlined team communication without getting lost in email inboxes. Chatbot alerts can be interactive, allowing engineers to acknowledge or comment right in chat.

Ticketing systems

Connecting monitoring tools to ticketing platforms such as Jira Service Desk, Zendesk, or Freshdesk enables automatic alerts to generate support tickets. Ticket priority and assignment can be customized based on alert attributes. This integration is helpful for customer-impacting incidents.

ITSM tools

IT service management tools like ServiceNow contain dedicated event management and incident response modules. Integrating monitoring systems allows events and alerts to generate ITSM records automatically. This provides a single system of record for efficient incident resolution.


Visualizing monitoring data on dashboards is useful for at-a-glance observability. Many monitoring tools have built-in dashboarding capabilities. They can also integrate with dedicated dashboarding tools like Datadog, Grafana, or Kibana for additional customization options. Alerts can be displayed directly on dashboards for easy visibility.

Notifications platforms

Dedicated notification channels like PagerTree allow grouping IT teams into schedules and escalation policies. Integrating monitoring systems with these platforms enables alerts to reach the right person at the right time based on customizable rules. This is helpful for after-hours coverage.

Workflow automation

Some monitoring tools integrate with workflow automation platforms like Rundeck or StackStorm. This automatically kicks workflows or playbooks off automatically based on alert triggers. Automating repetitive responses to common alerts increases efficiency.

The right integrations can maximize the value of your monitoring and alerting system. Consider which tools your team already uses and how connecting them could optimize observability and incident response workflows. Leverage integrations to build a more effective alerting system.
