# RabbitMQ Node Resource Exhaustion.
---

This incident type refers to a situation where a RabbitMQ node in a system has exhausted its resources, such as CPU, memory, or disk space. This can lead to various issues, including degraded system performance, failed message deliveries, and even system downtime. It is important to address this type of incident promptly to restore normal system operation and prevent any data loss.

### Parameters
```shell
export YOUR_NODE_NAME="PLACEHOLDER"

export NEW_CPU_ALLOCATION="PLACEHOLDER"

export NEW_MEMORY_ALLOCATION="PLACEHOLDER"
```

## Debug

### Check RabbitMQ queue sizes
```shell
sudo rabbitmqctl list_queues
```

### Check RabbitMQ node status
```shell
sudo rabbitmqctl status
```

### Check RabbitMQ node resource utilization
```shell
sudo rabbitmqctl eval 'erlang:memory().'
```

### Check system memory usage
```shell
free -m
```

### Check system CPU usage
```shell
top
```

### Check system disk usage
```shell
df -h
```

### Check RabbitMQ cluster status
```shell
sudo rabbitmqctl cluster_status
```

### Check system network usage
```shell
sudo netstat -tunap
```

## Repair

### Increase the resources allocated to the RabbitMQ node, such as CPU, memory, and disk space.
```shell
bash

#!/bin/bash



# Define the RabbitMQ node name and desired resource allocation

NODE_NAME=${YOUR_NODE_NAME}

CPU_ALLOCATION=${NEW_CPU_ALLOCATION}

MEMORY_ALLOCATION=${NEW_MEMORY_ALLOCATION}



# Stop the RabbitMQ node

sudo systemctl stop rabbitmq-server@$NODE_NAME.service



# Edit the RabbitMQ node config file to increase CPU and memory allocation

sudo sed -i "s/CPU_LIMIT=.*$/CPU_LIMIT=$CPU_ALLOCATION/" /etc/rabbitmq/rabbitmq-env.conf

sudo sed -i "s/MEMORY_LIMIT=.*$/MEMORY_LIMIT=$MEMORY_ALLOCATION/" /etc/rabbitmq/rabbitmq-env.conf



# Start the RabbitMQ node

sudo systemctl start rabbitmq-server.service



# Verify that the node is running with the new resource allocation

sudo systemctl status rabbitmq-server.service


```
