Introduction​

There are different ways you can use to deploy the Prometheus monitoring tool in your environment. One of the fastest ways to get started is to deploy it as a Docker container. This guide shows you how to quickly set up a minimal Prometheus on your laptop. You can then extend that setup to add a monitoring dashboard, alerting, and authentication.

Deploying Prometheus in a Docker Container​

Basic Setup​

Running Prometheus in Docker is very simple using this command

docker run -p 9000:9090 prometheus prom/prometheus:v3.0.0

This will pull and run the latest version (as of this writing) of Prometheus. You can access the Prometheus UI at localhost:9000. Note that the container port 9090 is forwarded to the localhost port 9000.

Introduction​

The Prometheus monitoring tool can store its metrics either locally or remotely. You can configure a remote data store using the remote_write configuration. This article describes the various data store options available as well as how to set up a remote store.

Overview of Remote Storage​

By default, Prometheus stores data locally wherever it is installed. The data directory can be configured by using the --storage.tsdb.path command line option when starting Prometheus. In practice you can use a separate disk for higher performance attached to the machine where Prometheus is running.

However, this may not be possible or optimal in all situations as you might want a data store that is more suited for time series data, and has larger storage capabilities for higher data retention. Prometheus would usually run in a standalone VM or a Kubernetes pod or a Docker container, and it would not have access to such data stores by default.

A remote store can add these capabilities to Prometheus. The remote storage option can be set by using the remote_write key in the Prometheus configuration YAML file.

Introduction​

Service discovery (SD) is a mechanism by which the Prometheus monitoring tool can discover monitorable targets automatically. Instead of listing down each and every target to be scraped in the Prometheus configuration, service discovery acts as a source of targets that Prometheus can query at runtime.

Service discovery becomes crucial when there are dynamically changing hosts, especially in microservices architectures and environments like Kubernetes. In Prometheus parlance, service discovery is a way of discovering "scrape targets".

For example, pods are created dynamically in Kubernetes as a result of new services being deployed and undeployed, autoscaling events, and errors causing pods to crash and go away. If you are using Prometheus for scraping pods in such an environment, Prometheus has to know which pods are running and scrapable at any given point in time. The Kubernetes service discovery pluging enables this. Similarly, there are SD plugins for other common environments.

You can use service discovery in Prometheus with the predefined plugins, or write your own custom ones using file or HTTP, depending on the situation.

Introduction​

Runbooks are a key part of incident management and preserve institutional knowledge. They can be used for both incident response as well as routine tasks like db maintenance and generating a complex report. We are mostly focused on incident response runbooks here.

Best Practices​

1. Runbook Structure​

• Establish a standard format that will be used across your organization. This will ensure consistency and help on-call folks to quickly figure out the steps even for runbooks they may not have seen before. It will also help in editing and maintaining the runbooks.
• Get buy-in from your team on the decided format. If you don't have buy-in people might not want to maintain or use them.
• Create the runbooks as decision trees. You don't need a visual guide here but include it if it's easy to create. Don't have too many branches in the tree - that will cause confusion. If you find yourself adding

Introduction​

Incident management tools are important for organizations to effectively handle service outages.

Why is Slack becoming so popular in incident management?

Slack is one of the most popular communication tools used in companies. If you're part of a remote team, your team is probably on Slack or something similar like MS Teams. Although IM tools lack the communication nuances that are taken for granted in face to face interactions, they provide many other advantages:

• Access to historical data
• Asynchronous communication
• The ability to share links and documents easily
• Adding anybody in the organization to a conversation

Slack in Incident Management​

One of the trends I've noticed in incident management is the growing rise of Slack in incident response and management tools. I think this is tied to the increase in remote work after COVID-19.

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.

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​

Staying on top of your third-party Cloud and SaaS service outages is crucial to maintain the reliability of your own applications. Like many modern teams, Slack might be your communication tool of choice. You can keep up with such incidents by pushing these events to a Slack channel.

There are different ways of pushing incident events to Slack. In this article we will explore how to integrate IncidentHub incident lifecycle events using an incoming webhook. An incoming webhook can be used to send incident trigger, update, and resolve events to a specific Slack channel.

Note that IncidentHub also has an option to integrate with custom webhooks, which is different from Slack's webhooks. If you are using Slack, choose the Slack option. For a custom webhook server, choose the Webhook option. The format of the Slack webhook payload is different from that of the Slack webhook.

Slack Incoming Webhook Configuration​

You must have the correct permissions on your Slack workspace to be able to do this.

Follow these steps to configure an incoming webhook in your Slack workspace.
