Prerequisites for EventLog Analyzer distributed edition

Prerequisites for converting to distributed edition

Here are a few of the prerequisites which need to be taken care of before converting a standalone setup to the distributed edition:

1. Ensure there is communication between the admin server and the managed servers bidirectional accessibility or via VPN and optimal functionality by opening the port in the firewall.
2. EventLog Analyzer requires the following ports to be free for web server and PostgreSQL communication.
• 33335 (TCP) - This is the port used for connecting to the bundled PostgreSQL database in EventLog Analyzer.
• 8400 (Web server port)- This is the default web server port used by EventLog Analyzer. This port is used for connecting to EventLog Analyzer using a web browser. You can change this port during installation.

By default, the managed and admin server communicate using HTTP (port number 8400). There is also an option to convert the mode of communication to HTTPS. Verify port availability to ensure it is unoccupied by concurrent local applications.

Best practices to deploy the admin and managed server

1. It is always recommended to convert the new EventLog Analyzer server as admin server to prevent data loss. You can follow the steps given here to convert the standard edition of EventLog Analyzer into an admin server.
2. For managed server, in case, you already have an existing EventLog Analyzer server, you can convert it into a managed server by following the steps here. The data in this case will remain on the same server and will not get lost/formatted unlike in the admin server.
3. Both the admin server and the managed server should be in the same build. If they are not in the same build, follow the steps mentioned here to download and apply the latest service packs.
• If both the admin and managed servers are not in the same build, it can lead to sync issues.
• One admin server is designed to manage up to 50 managed servers.

Licensing details of distributed edition

EventLog Analyzer's Distributed Edition license will be applied to the admin server. The number of devices and applications for which the license has been purchased can be utilized amongst the registered managed servers. You can keep adding the devices and applications in various managed servers until the purchased device licenses are exhausted. You can view the number of devices and applications managed by each managed server in the Managed Server Settings page of the admin server.

When the number of devices and applications managed by all the managed servers exceeds the number of licenses purchased, a warning message appears in the admin server. To resolve this warning, you can:

• Purchase the license to manage the additional devices and applications.
• Check the number of devices and applications managed by each managed server in the Managed Server Settings page of the admin server. Go to the individual managed server and manually manage the devices. Make sure that the number of devices and applications are within the license limit.
• Go to the individual managed server and manually manage the devices. Make sure that the number of devices and applications are within the license limit.
