You will need to perform some configurations on Extreme Network so that you can see the logs from your Extreme Network device over the Logsign.
First of all, connect to the switch console via ssh connection.
The following commands are executed for syslog forwarding process.
conf syslog add logsignip vr “VR-Default” local0
conf syslog logsignip vr “VR-Default” local0 severity info
enable log target syslog logsignip vr “VR-Default” local0
After configuration process, the source is ready to be integrated into Logsign.
Open the Logsign SIEM WEB interface and click on the "+ Device" button under the Data Collection tab, which is then clicked on the Settings tab in the menu bar on the top of the page. In the Source Type Selection page, choose Syslog as the method. After that, Extreme is selected as Vendor information. Finally define product and add other fields for integration.
Host: IP address information of the Extreme product that you want to retrieve the logs.
Encoding: utf_8, which is accepted as the general standard in Information Technologies, is set as default. Agree in the same way.
Offset: To explain it in terms of definition, let's say "time difference." If the "system" time you want to log in is forward or backward from the real-time difference, you can edit it accordingly. The symbol "+" moves forward, and "-" moves backward. Time information is specified in minutes.
Data Policy: As a definition, you can filter in or out of incoming data. In the Data Policy section, you can specify the kind of logs (word, event movement type, etc.) that you want to receive or not from the source. The default setting here is the Default Policy, which has the default rule is "collect all logs."
Max Line Length to Process: Each log is generated as a single line. So, the Logsign SIEM product takes these logs and analyzes them. In some cases, the number of characters in a single line of a single log file can be more significant than two thousand forty-eight (2048). In such cases, you can change this part.
Check Health: If you tick this box, that will inform you about the service and operability of the Logsign SIEM product. The Health Check Period tab will come up when the box is ticked. This part is the time interval information to be checked.
Device Name: You must enter a descriptive name according to the configuration you are making (For ex., ExtremeNetwork). It can provide convenience for people who analyze logs. You can think of the Description field as a resource-specific area.
Tag: Slightly different from the Description section, it can be used for a broader purpose. For example, you can query by tag; and make tag-based definitions while creating a report if you use multiple switches and define each tag as Extreme1 or Extreme2. If you want to query about an event, you will get a shorter result when you search according to Extreme1 name.
After filling the Tag section, click on the Save button to add the Extreme Network device to which you've configured the source.
