Logs

To check the logs for the different microservices of Klayr Service, use the command pm2 logs PROCESS_NAME, where PROCESS_NAME is the respective PM2-managed process that contains the logs you wish to view.

Alternatively, it is also possible to check the logs for a specific PM2 process based on its process ID. For example, pm2 logs 0 can be used to check the Klayr Service Gateway logs.

The process ID of each PM2-managed process can be seen by executing the List command. To learn more about PM2 log management please refer the PM2 logs documentation.

For example, to see the logs for the Gateway microservice, execute the following command:

pm2 logs klayr-service-gateway

Taking Snapshots

If you wish to take a snapshot of your Source-based installation, the details can be found here on the Snapshots page.

Resetting Klayr Service

Clean all run-time files with dependencies

make clean-local

Response

Example output

rm -rf node_modules
cd ./framework && rm -rf node_modules
cd ./services/blockchain-app-registry && rm -rf node_modules
cd ./services/blockchain-connector && rm -rf node_modules
cd ./services/blockchain-coordinator && rm -rf node_modules
cd ./services/blockchain-indexer && rm -rf node_modules

cd ./services/gateway && rm -rf node_modules
cd ./services/export && rm -rf node_modules
cd ./services/template && rm -rf node_modules
cd ./tests && rm -rf node_modules

Install npm dependencies

make build-local

Reset the Klayr Service database

To reset the database of Klayr Service, drop the respective MySQL and Redis databases.

Drop the MySQL database

Stop Klayr Service
```
yarn stop
```
Login to MySQL with the klayr user.
```
mysql -u klayr -ppassword
```
Drop the database.
```
mysql> drop database klayr;
```
Create a fresh database.
```
mysql> create database klayr;
```
Quit MySQL.
```
mysql> quit;
```

The process to re-index all the data commences after Klayr Service starts again following a database reset. The process can be rather time-consuming and could take several hours, depending on the length of the chain.

Flush Redis DB

Reset the databases for Redis after dropping the MySQL database:

redis-cli flushall

The flushall command truncates all existing Redis databases:

Deletes all the keys of all the existing databases, not just the current selected one. This command never fails.

For more information, check the Redis documentation: FLUSHALL.

To flush only a particular database in Redis, execute the following command instead:

redis-cli -n <db_number> flushdb

You can start Klayr Service again with the Start command.

Upgrade Klayr Service

To upgrade Klayr Service to a desired version, please follow the steps listed below. To find all the tagged versions for Klayr Service, please check the available tags on GitHub.

Stop the existing running version of Klayr Service.

pm2 stop ecosystem.config.js
