Installing EMA
EMA is distributed as a Docker image tar file.
To install EMA
1. Download the tar file from http://esd.actian.com.
2. Extract the contents of the uncompressed EMA image:
tar xvf actian_ema.4.0.tar
3. Check the MD5 checksum:
md5sum --check md5sum.txt
4. Run the install command:
./install.sh [-r external_directory]
You can specify a directory that will be used for external storage. External storage is used to persist the EMA configuration. Specify a directory that exists and that your current user can write to. If you do not specify an external directory, the current working directory is used.
The installer imports the Docker container into Docker and prompts for values needed to configure and start the container.
5. Respond to the prompts:
• What is the desired port number for the Web dashboard?
The port must be available on the machine you are installing on. The default is 80.
• Contact name and Contact email
Your name and email address for notifications.
• Host name
Starting with Host name, the installer prompts for the details of the sites to be monitored, from which EMA establishes a default configuration.

6. When prompted, log in to the remote host(s) with the "ingres" user ID.
When the access setup completes, the remote host information is reported. The installation confirms that Nagios is running.
