When teams manage a high volume of alerts, it’s easy for things to start blending together. A system outage, a temperature warning, a network slowdown – without a way to quickly identify what’s what, it takes longer to triage and prioritize. Especially on mobile, scrolling through a list of similar-looking alerts can slow your response and add confusion during incidents.
SIGNL4 Categories give you a simple but powerful way to visually and logically classify alerts – so teams can spot, sort, and act on them faster.
Why It Matters
Not all alerts are created equal. Some are high-impact and time-sensitive, while others are informational. Without clear identification, critical issues can get buried under lower-priority messages – or acknowledged by mistake.
With Categories, SIGNL4 helps you:
- Highlight alerts by type (e.g. network, application, facilities)
- Tag alerts by source system or customer site
- Color-code different event classes for fast recognition
- Reduce decision time during triage
The result is fewer missed alerts, faster reactions, and cleaner alert workflows – especially when you’re on the move or on-call.
Step-by-Step: How to Use Categories to Identify Alert Type
SIGNL4 includes built-in categories that help you immediately start classifying alerts. These categories aren’t just cosmetic – they let you sort, identify, and act on alerts faster by visually tagging them based on keyword matches in the alert content.
1. Explore and Customize the Built-In Categories
In the SIGNL4 web portal, navigate to Teams > Categories in the left-hand menu. Here you’ll see a list of preconfigured categories that come standard with every subscription.
Each category includes:
- A name
- An icon
- A color
- A list of trigger keywords
These categories are automatically applied to alerts that contain matching keywords – no additional configuration needed. However, you’re not locked into the defaults.
You can:
- Edit existing categories to better reflect your terminology, severity levels, or event types. This includes adjusting icons, colors, and keyword lists.
- Create new categories to represent specific systems, departments, environments, or alert types – giving you even more control over how alerts are classified.
2. Use Allow and Block Lists to Fine-Tune Category Assignment
Each category has two keyword “buckets” that determine how it gets applied:
- Allow List – These are the keywords that, when found in an alert, enable the category. You can include as many as you need. If multiple categories match, SIGNL4 applies the one with the most keyword matches.
Tip: Make sure your keywords are unique across categories to avoid overlap and ensure precise classification. - Block List – If any of these keywords are present in the alert, the category is explicitly excluded, even if allow list keywords match. This is helpful when certain phrases should never trigger a category – such as test alerts or known false positives.
This dual-list system gives you granular control, so you’re not stuck with vague matches or overly broad triggers.
3. Use Categories to Clean Up and Clarify Alert Content
Categories can do more than just tag alerts visually – they can also override the alert title and text, making messages easier to understand.
This is especially useful when alerts are generated by monitoring tools or IoT systems that produce raw, technical, or unclear messages. With a category, you can:
- Replace cryptic titles with clean, descriptive ones
- Add context for operators or on-call engineers
- Standardize formatting across different sources
Example:
A raw alert with a title like
ALR-2432: TMP_HV_89_1 exceeded threshold
can be transformed into:
Temperature Warning – Dallas Data Center
with just one category rule.
Pro Tip: Link to Playbooks or Docs for Faster Resolution
You can enrich category-based overrides with embedded links to relevant documentation, manuals, or response guides.
For example, your alert text might include:
Refer to [Cooling System Recovery Guide](https://kb.example.com/cooling-recovery) for resolution steps.
This turns each alert into a self-contained response unit – no more searching for runbooks or internal wikis when the clock is ticking.
Mobile App: See Categories at a Glance
Categories aren’t just useful in the web portal – they’re front and center in the SIGNL4 mobile app, where real-time alert clarity matters most.
Here’s what you’ll see:
- Each alert in your feed displays its color-coded category badge, making it easy to spot patterns.
- The category label also appears in the alert details view, helping on-call users instantly recognize what type of issue they’re dealing with – even before reading the full message.
For engineers in the field or on-call overnight, this reduces the mental overhead of parsing through raw alerts. No more guessing whether something’s a facility issue, a database failure, or a simple test ping – it’s immediately visible.
Pro Tip: Mute or Opt Out of Categories in the Mobile App
Not every alert is relevant to every team member – and SIGNL4 gives you options to filter the noise without breaking visibility for others.
From the Settings > Categories section in the mobile app, users can:
- Mute a category: Alerts will still appear in the feed, but won’t trigger push, SMS, voice, or email notifications. This is great for non-critical categories you still want to monitor passively.
- Opt out of a category entirely: If a user opts out, those alerts will not show up in their app at all. This is useful for teams that share a SIGNL4 group but divide responsibilities by role, system type, or geography.
These controls give users a personal way to manage alert relevance, without needing to restructure teams or routing logic. It’s a lightweight way to prevent alert fatigue while keeping critical alerts front and center.
What to Do Next
- Visit Categories in your SIGNL4 portal
- Create a few test categories based on keywords like “network” or “temp”
- Send a test alert and see how it looks in the mobile app
- Start structuring your alerts for faster, more confident responses
