EPAM Cloud Orchestrator provides the users with a GrayLog-based Log Aggregator Service that collects the logs from the specified instances and gives an easy and visual access to them via a web-interface. The service is based on GrayLog v.2.3.1.

Related CLI Commands
The table below provides the list of service-related commands and their descriptions:
| Command | Short Command | Description |
| or2-manage-service ... -s log -a | or2ms ... -s log -a | Starts the service in the specified project and region |
| or2-start-logging | or2log | Start collecting logs from the specified instance |
| or2-describe-logging | or2dlog | Describes the log aggregation service of the project |
| or2-stop-logging | or2stoplog | Stops collecting logs from the specified instance |
Further on this page, you can find the examples of the commands usage for Log Aggregation Service manipulation.
Service Activation
To start the service, use the or2-manage-service command with the following parameters:
or2ms -p project -r region -s log --activate
Here, the -s parameter specifies the name of the service to manage (log), and the --activate parameter indicates that the service should be activated (to stop the service, use --deactivate).
During the service activation, a VM with is started and a GrayLog server is configured on it. The server setup is a complicated process and can take up to an hour. If the project already has a GrayLog Server, you will get the respective error message.
The GrayLog-based Log Aggregator Service is not available for Microsoft Azure.
Service Manipulations
EPAM Orchestrator supports the following commands for Log service manipulations:
When the server is activated, you can start adding instances to the logging list, which allows to collect logs from these instances. This is done with the or2-start-logging (or2log) command:
or2log -p project -r region -i instance_id
- To get the list of the logged instances and the DNS name of the GrayLog Server, use the or2-describe-logging (or2dlog)command:
or2dlog -p project -r region
- To remove the instance from the Logging Service list, use the or2-stop-logging (or2stoplog) command:
or2stoplog -p project -r region -i instance_id
The server stops collecting the instance log data, but all the logs, previously aggregated, are kept.
- To stop the log aggregation service and remove the GrayLog Server VM, run the following command:
or2ms -p project -r region -s log --deactivate
Web UI and Viewing Logs
You can view the collected logs by connecting to the Log Server via HTTP. The typical address template for connecting to Log Server is:
http://<LogServerInstanceDNS>
The login and password that are to be used during the login to the server are returned at or2-describe-services command call:

When you log in, you will get to GrayLog Web Interface that provides you with the full access to the gathered data.

Pricing
The service usage price is defined by the price of the GrayLog Server VM.
The default parameters of a GrayLog Server VM are:
- Shape: MEDIUM
- Image: Ubuntu16.04_64-bit
Therefore, the approximate monthly cost of a GrayLog Server usage in case of 100% and 24/7 load is about $41.53 in EPAM-BY2 region (as to 08/07/2018). The price can vary depending on the region. To get more detailed estimations, please, use our Cost Estimator tool.
