Optimize this exporter
system_metrics = { "system_ram_usage": Gauge("system_ram_usage", "RAM usage", ["timestamp"]), "system_uptime": Gauge("system_uptime", "System uptime", ["timestamp"]), "system_temperature": Gauge( "system_temperature", "System temperature", ["timestamp"] ), "system_cpu_usage": Gauge("system_cpu_usage", "CPU usage", ["timestamp"]), }
To optimize the exporter for system metrics, we can consider a few strategies:
Reduce Redundancy: Since all the metrics share the same label (timestamp
), we can create a single metric with multiple values instead of separate metrics for each. This can help reduce the overhead of managing multiple gauges.
Use a Single Gauge with Multiple Labels: If the metrics are related and can be represented together, we can use a single gauge with multiple labels to differentiate between them.
Batch Updates: If the metrics are being updated frequently, consider batching the updates to reduce the number of calls to the monitoring system.
Use a Dictionary for Dynamic Metric Creation: If you plan to add more metrics in the future, using a dictionary to dynamically create and manage metrics can be more efficient.
Here’s an optimized version of your exporter:
from prometheus_client import Gauge
# Define a single gauge with multiple labels
system_metrics = Gauge(
"system_metrics",
"System metrics",
["metric_type", "timestamp"]
)
# Function to set the metrics
def set_system_metric(metric_type, value, timestamp):
system_metrics.labels(metric_type=metric_type, timestamp=timestamp).set(value)
# Example usage
def update_metrics():
import time
current_timestamp = int(time.time())
# Example values for demonstration
ram_usage = 70.5 # Example RAM usage percentage
uptime = 3600 # Example uptime in seconds
temperature = 55.0 # Example temperature in Celsius
cpu_usage = 30.0 # Example CPU usage percentage
# Update metrics
set_system_metric("system_ram_usage", ram_usage, current_timestamp)
set_system_metric("system_uptime", uptime, current_timestamp)
set_system_metric("system_temperature", temperature, current_timestamp)
set_system_metric("system_cpu_usage", cpu_usage, current_timestamp)
# Call the update_metrics function periodically
Single Gauge: We created a single Gauge
called system_metrics
that takes metric_type
and timestamp
as labels. This reduces the number of separate gauge instances.
Dynamic Metric Setting: The set_system_metric
function allows you to set the value of any metric type dynamically, making it easier to manage and update.
Example Usage: The update_metrics
function demonstrates how to update the metrics with example values.
This approach is more efficient and scalable, especially if you plan to add more metrics in the future.
