📋 What You'll Learn

Create a log entry with a specific name and message

Set a filter string to find logs with a certain severity

Use the gcloud command to list logs matching the filter

Display the filtered log entries

💡 Why This Matters

🌍 Real World

Cloud Logging helps cloud engineers and developers monitor their applications and infrastructure by collecting logs from various cloud services in one place.

💼 Career

Knowing how to create, filter, and view logs is essential for troubleshooting, auditing, and maintaining cloud systems in roles like Cloud Engineer or DevOps Specialist.

1

Create a log entry

Use the gcloud logging write command to create a log entry named my-log with the message "Hello Cloud Logging" and severity INFO.

GCP

# Use gcloud logging write to create a log entry named 'my-log' with message 'Hello Cloud Logging' and severity INFO
# Your code here

Need a hint?

Use gcloud logging write LOG_NAME MESSAGE --severity=SEVERITY format.

2

Set a filter for severity

Create a variable called filter and set it to the string "severity=INFO" to filter logs with INFO severity.

GCP

gcloud logging write my-log "Hello Cloud Logging" --severity=INFO
# Create a variable called filter and set it to "severity=INFO"
# Your code here

Need a hint?

Assign the string exactly as "severity=INFO" to the variable filter.

3

List logs using the filter

Use the gcloud logging read command with the filter variable filter to list log entries that have severity INFO.

GCP

gcloud logging write my-log "Hello Cloud Logging" --severity=INFO
filter="severity=INFO"
# Use gcloud logging read with the filter variable to list logs
# Your code here

Need a hint?

Use gcloud logging read "$filter" to apply the filter variable.

4

Display the filtered logs

Run the command to display the filtered logs and verify that the log entry with message "Hello Cloud Logging" appears in the output.

GCP

gcloud logging write my-log "Hello Cloud Logging" --severity=INFO
filter="severity=INFO"
gcloud logging read "$filter"
# Run the above command to display logs
# Your code here

Need a hint?

Check the output for the message Hello Cloud Logging.
