Log-based metrics in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What are log-based metrics in Google Cloud?

Log-based metrics are measurements created from logs data. They help track and count specific events or patterns found in logs to monitor system behavior.

beginner

How do log-based metrics differ from regular metrics?

Regular metrics come from system data like CPU or memory usage. Log-based metrics come from analyzing log entries to count or measure specific events.

What are the two types of log-based metrics in Google Cloud?

There are two types: Counter metrics, which count how many times something happens, and Distribution metrics, which measure values like latency or size from logs.

beginner

Why use log-based metrics instead of just reading logs?

Log-based metrics summarize log data into numbers you can graph and alert on. This makes it easier to spot trends and problems quickly without reading all logs.

beginner

What is a common use case for log-based metrics?

A common use is counting error messages in logs to alert when errors increase, helping teams fix issues faster.

What does a counter log-based metric do?

A Measures the size of log files

B Counts how many times a specific event occurs

C Tracks CPU usage over time

D Stores raw log data

Counter metrics count occurrences of events found in logs.

Which Google Cloud service is used to create log-based metrics?

A Cloud Logging

B Cloud Storage

C Cloud Functions

D Cloud SQL

Cloud Logging collects logs and allows creation of log-based metrics.

What type of log-based metric would you use to measure request latency from logs?

A Counter metric

B Gauge metric

C Boolean metric

D Distribution metric

Distribution metrics measure values like latency or size from logs.

Why are log-based metrics useful for monitoring?

A They store logs in a database

B They replace logs completely

C They convert log data into numbers for easy tracking and alerting

D They encrypt logs for security

Log-based metrics summarize logs into measurable data for monitoring.

Which of the following is NOT a feature of log-based metrics?

A Automatically fixing errors found in logs

B Measuring values from logs

C Triggering alerts based on log data

D Counting specific log events

Log-based metrics do not fix errors; they help detect and alert on them.

Explain what log-based metrics are and why they are useful in cloud monitoring.

Think about how logs can be turned into numbers to watch system health.

Describe the two types of log-based metrics and give an example use case for each.

One counts events, the other measures values like latency.
