# 7. Load testing MongoDB

## a. Initialize records of MongoDB

- mongo-express console URL and login using admin/admin credentials.

```bash

http://localhost:8081/db/local_mongo_db/

```

![My Image](./_external_files/screenshot_mongo_init.png)

- Import postman collections from employee-service/_external_files/Mongo-MySQL performance.postman_collection.json.

- Execute POST Mongo 10M employee records insert.

![My Image](./_external_files/postman_mongo_insert.png)  

- Verify the records inserted via mongo-express console.

![My Image](./_external_files/screenshot_mongo_records.png)

## b. Perform MongoDB loadtest

- Copy the JMeter script to JMeter bin directory.

```bash

JMeter script --> employee-service/_external_files/employee-mongo.jmx

JMeter bin --> /bin

Copy  to 

```

- Execute the below commands in JMeter bin directory:

```bash

mkdir employee-mongo-report

./jmeter.sh -n -t employee-mongo.jmx -l employee-mongo-report/mongo-loadtest.jtl -e -o employee-mongo-report/

```

- View MongoDB loadtest report in: Refer in section 2-c-i

```bash

/bin/employee-mongo-report/index.html

```

# 8. Load testing MySQL

## a. Initialize records of MySQL

- Import postman collections from employee-service/_external_files/Mongo-MySQL performance.postman_collection.json.

- Execute POST MySQL 10M employee records insert.

![My Image](./_external_files/postman_mysql_insert.png)

- Verify the records inserted via mongo-express console.

![My Image](./_external_files/screenshot_mysql_records.png)

## b. Perform MySQL loadtest with default max_connections

- Copy the JMeter script to JMeter bin directory.

```bash

JMeter script --> employee-service/_external_files/employee-mysql.jmx

JMeter bin --> /bin

Copy  to 

```

- Execute the below commands in JMeter bin directory:

```bash

mkdir employee-mysql-report

./jmeter.sh -n -t employee-mysql.jmx -l employee-mysql-report/mysql-loadtest.jtl -e -o employee-mysql-report/

```

- View MySQL loadtest report in: Refer in section 2-c-ii

```bash

/bin/employee-mysql-report/index.html

```

## c. Perform MySQL loadtest with max_connections=1000. Fine tuned.

- Set MySQL max_connections=1000

![My Image](./_external_files/screenshot_mysql_max_conn.png)

- Execute the below commands in JMeter bin directory:

```bash

mkdir employee-mysql-report-max-conn

./jmeter.sh -n -t employee-mysql.jmx -l employee-mysql-report-max-conn/mysql-loadtest.jtl -e -o employee-mysql-report-max-conn/

```

- View MySQL loadtest report in: Refer in section 2-c-iii

```bash

/bin/employee-mysql-report-max-conn/index.html

```
