how to monitor network logs

[surekhasplunk]

Hi,

I have cisco, checkpoint, fortinet, arista, pulse secure etc devices which needs to be monitored for network, bandwidth, packet drops usage etc.

So what would be the best approach to achieve it. Which app i should use

Thanks

No one app will handle all of those devices. Look in apps.splunk.com for apps that support the products you use.

Just installing apps may not be enough. Apps will process logs, but don't always fetch the logs themselves. You probably will have to configure the devices to send their logs in syslog format to a syslog server. Then install the Splunk Universal Forwarder on the syslog server to pass the logs to Splunk. See http://www.georgestarcher.com/splunk-success-with-syslog/.

What you can monitor for depends on the data provided to Splunk by your devices. For instance, you can't look for packet drops if packet drops are not logged.

This is a very general question. Feel free to post new, specific questions as you go.
