Sure, here is a Python script that simulates a basic AIOps process. This script will use a simplified version of a machine learning model to predict anomalies in system logs. For demonstration purposes, we will use synthetic data and a simple linear regression model.
« `python
import numpy as np
import pandas as pd
from sklearn.linear_model import LinearRegression
from sklearn.metrics import mean_squared_error
import matplotlib.pyplot as plt
# Generate synthetic data
np.random.seed(0)
data_size = 100
X = np.linspace(0, 10, data_size)
Y = 2 * X + np.random.normal(0, 1, data_size)
# Split data into training and testing sets
X_train, X_test = X[:80], X[80:]
Y_train, Y_test = Y[:80], Y[80:]
# Train a simple linear regression model
model = LinearRegression()
model.fit(X_train.reshape(-1, 1), Y_train)
# Make predictions
Y_pred = model.predict(X_test.reshape(-1, 1))
# Evaluate the model
mse = mean_squared_error(Y_test, Y_pred)
print(f »Mean Squared Error: {mse} »)
# Plot the results
plt.scatter(X, Y, color=’black’, label=’Actual Data’)
plt.plot(X_test, Y_pred, color=’blue’, linewidth=2, label=’Predicted Line’)
plt.xlabel(‘X’)
plt.ylabel(‘Y’)
plt.title(‘AIOps Anomaly Detection Simulation’)
plt.legend()
plt.show()
# Function to detect anomalies
def detect_anomalies(actual, predicted, threshold=2.0):
residuals = actual – predicted
anomalies = np.where(np.abs(residuals) > threshold)[0]
return anomalies
# Detect anomalies in the test data
anomalies = detect_anomalies(Y_test, Y_pred)
print(f »Detected anomalies at indices: {anomalies} »)
# Visualize anomalies
plt.scatter(X_test, Y_test, color=’black’, label=’Actual Data’)
plt.scatter(X_test[anomalies], Y_test[anomalies], color=’red’, label=’Anomalies’)
plt.plot(X_test, Y_pred, color=’blue’, linewidth=2, label=’Predicted Line’)

### Explanation:
1. **Data Generation**: We generate synthetic data using NumPy for demonstration purposes.
2. **Model Training**: A simple linear regression model is trained using the synthetic data.
3. **Prediction**: The model makes predictions on the test data.
4. **Evaluation**: Mean Squared Error (MSE) is calculated to evaluate the model’s performance.
5. **Anomaly Detection**: A function is defined to detect anomalies based on residuals.
6. **Visualization**: The results are plotted to visualize the actual data, predicted line, and detected anomalies.
This script provides a basic simulation of an AIOps process and can be extended with more complex models and real-world data for practical applications.
