Success during an outage depends on more than an engineer's skill—it requires a powerful, integrated toolkit. A single tool isn't enough to manage today's complex systems. Modern reliability is built on a stack of specialized site reliability engineering tools that work together, covering everything from the first alert to the final retrospective.
An effective DevOps incident management strategy needs tools for alerting, observability, collaboration, and automation. This guide covers the seven best tools for on-call engineers and shows how they form a cohesive stack to improve reliability.
The Pillars of Effective Incident Response
A modern on-call workflow is built on five key pillars that create a complete DevOps incident management lifecycle.
- Alerting & Scheduling: Getting the right notification to the right person, quickly and reliably.
- Observability: Providing the deep, contextual data needed to understand what's happening within a system.
- Coordination & Collaboration: Creating a central command center for responders to communicate and execute tasks.
- Automation & Remediation: Automating repetitive tasks to reduce manual work and accelerate resolution.
- Learning & Improvement: Analyzing incident data to document lessons and implement changes that prevent future failures.
7 Best Tools for Your On-Call Stack
The best tools for on-call engineers excel in one of these areas while integrating smoothly with the others. Here are seven essential tools that form a robust on-call stack.
1. Rootly (For End-to-End Incident Management)
Rootly acts as the central command platform for your entire incident response process. It automates the incident lifecycle directly within collaboration hubs like Slack or Microsoft Teams. When an incident is declared, Rootly automatically creates dedicated channels, pulls in the correct responders, assigns roles, and starts building a real-time timeline.
As a leading incident management software [3], its greatest strength is acting as an integration hub. It connects with other tools on this list—triggering from PagerDuty alerts, pulling in dashboards from Datadog, and creating tickets in Jira—to establish a single source of truth. Rootly also automates tasks like status page updates and generates retrospectives, turning a chaotic process into a structured workflow.
Tradeoff: A comprehensive platform like Rootly requires initial configuration to fit into your existing workflows. However, this upfront effort standardizes processes and automates work for every future incident.
2. PagerDuty (For On-Call Scheduling and Alerting)
PagerDuty is an industry standard for on-call scheduling and alert management [5]. Its primary function is to collect alerts from all your monitoring sources and ensure they reach the correct on-call engineer.
Features like customizable escalation policies and multi-channel notifications make it essential for teams that need a guaranteed fast response [2]. In an integrated stack, PagerDuty provides the critical "wake-up call," while a platform like Rootly takes over to manage the coordinated response.
Tradeoff: PagerDuty is a premium tool, and its cost can be a factor for some teams. If alert rules aren't carefully configured at the source, it can also lead to alert fatigue.
3. Datadog (For Comprehensive Observability)
Once alerted, an engineer's first question is, "What's happening?" Datadog helps answer that. It's an observability platform that unifies metrics, traces, and logs into a single view. This is where engineers diagnose problems, using dashboards to correlate events and pinpoint the root cause.
For teams managing complex microservices or containerized environments, Datadog is a cornerstone of an effective sre observability stack for kubernetes. The signals it generates are what feed into alerting tools like PagerDuty, kicking off the incident response process.
Tradeoff: Datadog's all-in-one nature comes at a premium price, and costs can grow quickly with data volume. The sheer amount of data can also be overwhelming without disciplined dashboarding and alert configuration.
4. Grafana (For Flexible Data Visualization)
While platforms like Datadog offer powerful all-in-one solutions, many teams prefer the flexibility of Grafana for data visualization. Grafana's key advantage is its ability to create dashboards from dozens of data sources, including Prometheus, Loki, and InfluxDB.
On-call engineers rely on pre-built Grafana dashboards to get a quick, consistent view of service health. Its flexibility makes it one of the most popular site reliability engineering tools for cutting MTTR (Mean Time to Resolution).
Tradeoff: Grafana is only a visualization layer. Your team is responsible for setting up and managing the underlying data sources and alerting logic (for example, with Prometheus and Alertmanager), which adds complexity.
5. Slack (For Real-Time Collaboration)
During an incident, clear, centralized communication is critical. Slack has become the default digital "war room" for incident response [1], providing a real-time space for responders and stakeholders to collaborate.
However, a plain Slack channel can quickly become chaotic. This is where integrations shine. Platforms like Rootly supercharge Slack with bot commands (like /rootly) that let teams run the entire incident—from declaring severity to assigning tasks—without leaving the chat interface.
Tradeoff: Without a structured tool operating within it, Slack can become disorganized. Important decisions get lost in conversation threads, and there is no clear audit trail of actions, making post-incident analysis difficult.
6. Opsgenie (For Integrated Atlassian On-Call Management)
Opsgenie is a strong alternative to PagerDuty, offering similar features for on-call scheduling, alerting, and escalations [4]. Its main differentiator is its deep, native integration with the Atlassian ecosystem.
For teams already using Jira for project tracking and Confluence for documentation, Opsgenie creates a more seamless workflow. This makes it a preferred on-call software for teams heavily invested in Atlassian's toolchain.
Tradeoff: Opsgenie's primary benefit can also be its biggest risk: vendor lock-in. If your organization isn't committed to the Atlassian suite, a more ecosystem-agnostic tool may offer greater flexibility.
7. Jira (For Post-Incident Action Items)
An incident isn't truly resolved until you've taken steps to prevent it from happening again. The output of every effective retrospective is a set of action items. Jira is the standard tool for turning those learnings into trackable engineering tickets.
This practice closes the loop on the incident lifecycle, ensuring that insights lead to concrete system improvements. By integrating directly with Jira, incident management platforms like Rootly can automatically create these follow-up tickets, driving accountability and improving long-term reliability.
Tradeoff: Jira can feel cumbersome, and manually creating tickets after a stressful incident leads to "process fatigue." The key is to reduce this friction by automating ticket creation directly from the incident.
Conclusion: Unify Your Tools for Better Reliability
The best tools for on-call engineers don't work in isolation; they form an integrated stack where each component has a critical role. From observability in Datadog and alerting with PagerDuty to collaboration in Slack and follow-up tracking in Jira, a cohesive toolkit is essential for modern reliability.
An integrated toolkit needs a central hub. Rootly unifies your favorite on-call tools into a single, automated workflow, cutting down on manual work and speeding up resolution.
