Hydra is a twitter-like social network.
- Assuming your tsung instance IP address is 34.222.195.237, from your local machine, run
rsync -auvL -e "ssh -i Hydra.pem" [email protected]:tsung_logs .to get the logs.
Since we are using docker as our local environment, first we need to get the docker container name in which the database is running. You can use docker ps command to get this. Then run the following commands:
docker exec -t your-db-container-name pg_dump your-db-name -U your-db-username > your-dump-filename.sql
-a will dump the data only, not the schema.
Example:
docker exec -t hydra_db_1 pg_dump app_development -a -U postgres > dump_hydra.sql
- ssh into app server
- Run
sudo su, then/opt/elasticbeanstalk/bin/get-config environment | jq -r 'to_entries | .[] | "export \(.key)=\"\(.value)\""' > /etc/profile.d/sh.local - Run
chmod 777 /etc/profile.d/sh.local - disconnect from the app server
- ssh into app server again, then run
cd /var/app/current && bin/rails db:seed. Ignore the errors and wait until the command is finished, and the app server should be seeded.
You need to have psql installed on your local machine. psql is a terminal-based front-end to PostgreSQL. For installation, you can use this link.
Then, run following command:
psql -f your-dump-filename.sql --host your-db-hostname-in-aws-rds --port port-used-in-your-aws-rds --username your-aws-rds-dbusername --dbname your-aws-rds-dbname
AWS RDS database details can be found inside the configuration file of your Elastic Benstalk environment.
Example:
psql -f dump_hydra.sql --host awseb-e-dxp3aesnek-stack-awsebrdsdatabase-slfaoe0pa7gq.cxsnhvva4y19.us-west-2.rds.amazonaws.com --port 5432 --username u --dbname ebdb
It will ask the password you provided during the deployment.
Done! Now you can see the data browsing your site.
Login to ec2 machine:
ssh -i Hydra.pem [email protected]
Launch Tsung
cd /usr/bin
launch_tsung.sh
This will output the ip address of the ec2 instance. ssh to that machine. Say the ip address is 35.86.238.45
If we have Tsung instances available, we don't need to create new ones. Go to the AWS management website and go to EC2 page. Then click into the instance (named Tsung-Hydra) and click "Connect". You will find "SSH client" tab, which will have something like:
ssh -i "Hydra.pem" [email protected]
Replace the root by ec2-user, and you can log into the instance directly.
tsung -f tsung_example.xml -k start
-k flag in the above step : keep the server running even after the test is done, so that we can analyze the various metrics from the test.
scp -i local-directory -r [email protected]: Log-directory ~/tsung-paginated-logs-view-users/
Example:
scp -i ~/Downloads/Hydra.pem -r [email protected]:/home/ec2-user/.tsung/log/20221122-0157 ~/tsung-paginated-logs-view-users/ ```
