# High Nginx Worker Load Incident
---

High Nginx Worker Load incident refers to the situation where the worker processes and connections on an Nginx server experience high load, which can cause a negative impact on the server's performance and response times. This can occur due to a wide range of factors, including high traffic volumes, poorly optimized configurations, or other factors that increase the demand on the server. As a result, it becomes necessary to resolve this issue by optimizing worker processes and connections to balance server load effectively and ensure the server can handle the load without any negative impacts on performance or response times.

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

export NUMBER_OF_WORKER_CONNECTIONS="PLACEHOLDER"

export PATH_TO_NGINX_CONF="PLACEHOLDER"

export URL="PLACEHOLDER"

export STATUS_PATH="PLACEHOLDER"
```

## Debug

### Check the current worker processes running
```shell
ps -ef | grep nginx | grep worker
```

### Check the current CPU and memory usage of the Nginx process
```shell
top -p ${NGINX_PROCESS_ID}
```

### Check the current Nginx configuration for thread support
```shell
nginx -V 2>&1 | grep --color -- --with-threads
```

### Check the current Nginx configuration for status module
```shell
nginx -V 2>&1 | grep --color -- --with-http_stub_status_module
```

### Check the Nginx status metrics
```shell
curl ${URL}/${STATUS_PATH}
```

## Repair

### Optimize worker connections to balance server load effectively.
```shell


#!/bin/bash



# Set the number of worker connections to optimize

worker_connections=${NUMBER_OF_WORKER_CONNECTIONS}



# Set the path to the Nginx configuration file

nginx_conf=${PATH_TO_NGINX_CONF}



# Backup the existing Nginx configuration file

cp $nginx_conf $nginx_conf.bak



# Update the Nginx configuration file with the new worker_connections value

sed -i "s/$worker_connections\s*$[0-9]\+;/\1$worker_connections;/" $nginx_conf



# Restart the Nginx service to apply the changes

service nginx restart



echo "Worker connections optimized successfully."


```
