Python script to monitor Kakfa Producer memory leak

Python script to monitor Kakfa Producer memory leak


A memory leak in a Kafka producer can occur when the producer is unable to release memory that is no longer needed. This can lead to poor performance and, in extreme cases, cause the producer to crash.

To monitor a Kafka producer for memory leaks, you can use a Python script that periodically checks the amount of memory used by the producer process. The script can then alert you when the memory usage exceeds a certain threshold.

Here is an example script that demonstrates how to monitor a Kafka producer for memory leaks using the psutil library:

import psutil
import time

def check_producer_memory():
# Find the process ID of the Kafka producer
for proc in psutil.process_iter():
if proc.name() == "java":
if "kafka-producer" in proc.cmdline():
pid = proc.pid
break
else:
print("Kafka producer not found")
return

# Set the threshold for the amount of memory that the producer can use
threshold = 100000000 # 100MB

# Check the producer's memory usage every 5 seconds
while True:
mem = psutil.Process(pid).memory_info().rss
if mem > threshold:
print(f"Kafka producer memory usage exceeded threshold: {mem} bytes")
time.sleep(5)

check_producer_memory()

The script uses the psutil library to find the process ID of the Kafka producer by iterating over all running processes and checking the command-line arguments of each process. If it finds a process with the name “java” and with “kafka-producer” in its command-line arguments, it considers it as the Kafka producer.

Once it has the process ID of the producer, it uses the psutil.Process class to check the producer’s memory usage every 5 seconds. If the memory usage exceeds a certain threshold (in this case, 100MB), it prints a message to alert you of the memory leak.

In summary, you can use a Python script to monitor a Kafka producer for memory leaks by using the psutil library to check the producer’s memory usage and alert you when the usage exceeds a certain threshold. The above script is a starting point, you can customize it to your needs and requirements.
