query {
agent {
id
name
status
}
}
You can use this query to monitor the health of your workers and take appropriate actions, such as restarting the worker if it becomes unhealthy.
To execute this query using Python, you can use the requests
library to send a POST request to the Prefect API endpoint. Here's an example:
python
import requests
import json
url = "<https://api.prefect.io/graphql>"
api_key = "YOUR_PREFECT_API_KEY"
query = """
query {
agent {
id
name
status
}
}
"""
headers = {
"Authorization": f"Bearer {api_key}",
"Content-Type": "application/json",
}
response = <http://requests.post|requests.post>(url, json={"query": query}, headers=headers)
data = response.json()
print(json.dumps(data, indent=2))
Replace YOUR_PREFECT_API_KEY
with your actual Prefect API key. This script will print the agents and their statuses. You can then use this information to restart the worker if needed.

endpoint. Here's an example using Python and the requests
library to fetch the agents and their statuses:
python
import requests
import json
url = "<https://api.prefect.io/graphql>"
api_key = "YOUR_PREFECT_API_KEY"
query = """
query {
agent {
id
name
status
}
}
"""
headers = {
"Authorization": f"Bearer {api_key}",
"Content-Type": "application/json",
}
response = <http://requests.post|requests.post>(url, json={"query": query}, headers=headers)
data = response.json()
print(json.dumps(data, indent=2))
Replace YOUR_PREFECT_API_KEY
with your actual Prefect API key. This script will print the agents and their statuses.
Regarding the Kubernetes pod livenessProbe, you can use an HTTP GET request to check the health of your worker. If you're using Prefect's Kubernetes agent, it exposes a health check endpoint at /healthz
. You can configure the livenessProbe in your Kubernetes deployment like this:
yaml
livenessProbe:
httpGet:
path: /healthz
port: 8080
initialDelaySeconds: 10
periodSeconds: 10
This configuration will send an HTTP GET request to the /healthz
endpoint on port 8080 every 10 seconds, starting 10 seconds after the container has started. If the health check fails, Kubernetes will restart the container.

library to fetch the agents and their last heartbeat:
python

api_key = "YOUR_PREFECT_API_KEY"
query = """

"Authorization": f"Bearer {api_key}",
"Content-Type": "application/json",
}
response = <http://requests.post|requests.post>(url, json={"query": query}, headers=headers)
data = response.json()
print(json.dumps(data, indent=2))
