Prometheus Recording Rules: Examples and Tips

Prometheus, the open-source monitoring and alerting toolkit, provides a powerful feature called Recording Rules. These rules allow users to create new time series based on existing metrics and apply various transformations and aggregations. In this article, we will explore some examples of Prometheus Recording Rules and provide useful tips to help you write effective rules.

Example 1: Calculating Request Latency Percentiles

Let’s say you have a metric called `http_request_duration_seconds` representing the duration of HTTP requests. You can create a recording rule to calculate the 95th percentile latency over a 5-minute window as follows:

“`

http_request_duration_seconds_quantile_95 = quantile_over_time(0.95, http_request_duration_seconds[5m])

“`

Example 2: Aggregating Metrics from Multiple Instances

If you have multiple instances of a service and want to aggregate their metrics, you can use recording rules. For instance, let’s assume you have a metric `cpu_usage` representing CPU usage on each instance. You can create a rule to calculate the average CPU usage across all instances:

“`

cpu_usage_average = avg(cpu_usage) without (instance)

“`

Example 3: Deriving Custom Metrics

Recording rules can also be used to derive custom metrics. For instance, let’s say you have a metric `http_requests_total` representing the total number of HTTP requests. You can create a rule to calculate the request rate per minute:

“`

http_requests_per_minute = rate(http_requests_total[1m])

“`

Tips for Writing Prometheus Recording Rules:

1. Keep rules simple and concise for better maintainability.

2. Use meaningful metric names to ensure clarity and ease of understanding.

3. Leverage functions and operators provided by Prometheus, such as `avg()`, `sum()`, `rate()`, etc., to perform calculations and transformations.

4. Test and validate your rules using Prometheus’s expression browser or the Alertmanager’s “Test Rule” feature.

5. Regularly review and update your recording rules as your monitoring needs evolve.

In conclusion, Prometheus Recording Rules offer a flexible way to create new time series and perform calculations on existing metrics. By following the examples and tips provided, you can effectively leverage this feature to gain deeper insights into your system’s performance. Remember to keep your rules concise, test them thoroughly, and adapt them as your monitoring requirements change.

prometheus recording rules naming

Prometheus is an open-source monitoring and alerting toolkit originally built at SoundCloud. It has gained immense popularity due to its powerful features and flexibility in monitoring various systems and applications. One of the key aspects of Prometheus is its recording rules, which allow users to define and create new time series based on existing ones.

Recording rules in Prometheus are used to precompute frequently needed or computationally expensive expressions. These rules help in reducing the load on the Prometheus server and allow for faster query evaluation. By defining recording rules, users can create new time series that are automatically generated and stored in the Prometheus database.

When naming recording rules, it is important to follow certain conventions to ensure clarity and consistency. Here are some recommended practices:

1. Use descriptive names: Choose names that accurately represent the purpose or behavior of the recording rule. This helps in understanding the rule’s functionality at a glance.

2. Be concise: Keep the names short and to the point. Long and complex names can make it difficult to read and comprehend the rules.

3. Use lowercase and underscores: Stick to lowercase letters and separate words with underscores. This convention enhances readability and makes it easier to differentiate between words.

4. Avoid special characters: Steer clear of special characters, symbols, or spaces in the names. Stick to alphanumeric characters and underscores to ensure compatibility and ease of use.

5. Be consistent: Maintain a consistent naming convention across all recording rules. This helps in organizing and managing rules effectively.

By following these guidelines, users can create a well-structured and easily understandable set of recording rules in Prometheus. This not only simplifies maintenance but also aids collaboration among team members.

In conclusion, recording rules in Prometheus play a crucial role in optimizing query performance and reducing server load. Naming these rules appropriately ensures clarity, consistency, and ease of understanding. With well-named recording rules, users can harness the full potential of Prometheus for efficient monitoring and alerting in their systems and applications.

prometheus recording rules labels

Prometheus recording rules are an essential aspect of monitoring and alerting in Prometheus, an open-source monitoring system. These rules allow users to define specific conditions and thresholds for recording time series data and triggering alerts based on those conditions.

Labels play a crucial role in Prometheus recording rules. Labels are key-value pairs that are attached to time series data, providing additional metadata. They help in organizing and categorizing metrics, making it easier to filter and query specific data.

When writing recording rules in Prometheus, labels are used to define the conditions for recording time series data. For example, a recording rule can be created to calculate the average response time for a specific API endpoint. By applying labels to the rule, such as the API endpoint name, the rule will only be applied to the relevant time series data.

Labels also enable users to aggregate and group time series data. This is especially useful when generating alerts based on certain conditions. For instance, labels can be used to group time series data by geographical region or server location, allowing users to set region-specific alert thresholds.

It is important to keep the content of recording rules concise and efficient. Prometheus recommends limiting the content to no more than 350 English words. This ensures that the rules remain manageable and do not become overly complex, which can lead to performance issues or difficulties in maintenance.

In conclusion, Prometheus recording rules are a powerful feature for monitoring and alerting. Labels play a crucial role in defining conditions and organizing time series data. Keeping the content of recording rules concise ensures their effectiveness and ease of management.

prometheus recording rules remote write

Prometheus recording rules provide a powerful mechanism to define and evaluate expressions based on existing metrics. These rules enable users to create new time series or modify existing ones, allowing for advanced monitoring and alerting capabilities.

One of the key features of Prometheus recording rules is the ability to perform a remote write. This means that instead of storing the results of the recording rule within the Prometheus server, it can be written to a remote storage system. This feature is particularly useful in scenarios where data needs to be centralized or shared across multiple Prometheus instances.

To enable remote write, users need to configure the Prometheus server with the appropriate remote write settings. This includes specifying the remote storage system’s endpoint, authentication credentials, and other relevant parameters. Once configured, Prometheus will send the recorded metrics to the remote storage system, where they can be stored, analyzed, or visualized using other tools.

Remote write offers several benefits. Firstly, it reduces the storage burden on the Prometheus server, as the recorded metrics are stored externally. This can be especially advantageous in high-traffic environments with large amounts of data. Additionally, remote write enables data sharing and centralization, allowing multiple Prometheus instances to contribute to a single, unified view of the system.

However, there are some considerations to keep in mind when using remote write. The remote storage system needs to be compatible with Prometheus’ remote write API, and its performance and reliability should be carefully evaluated. Additionally, the security of the remote write connection must be ensured to protect sensitive data.

In conclusion, Prometheus recording rules provide a flexible way to create and manipulate metrics. Remote write is a valuable feature that allows metrics to be stored in an external system, enabling data sharing and reducing the storage burden on the Prometheus server. Careful configuration and evaluation of the remote storage system are essential for successful implementation.
