We are looking to deploy Edge Processors (EP) in a high availability configuration - with 2 EP systems per site and multiple sites. We need to use Edge Processors (or Heavy Fowarders, I guess?) to ingest and filter/transform the event logs before they leave our environment and go to our MSSP Splunk Cloud. Ideally, I want the Universal Forwarders (UF) to use the local site EPs. However, in the case that those are unavailable, I would like the UFs to failover to use the EPs at another site. I do not want to have the UFs use the EPs at another site by default, as this will increase WAN costs, so I can't simply list all the servers in the defaultGroup. For example: [tcpout]
defaultGroup=site_one_ingest
[tcpout:site_one_ingest]
disabled=false
server=10.1.0.1:9997,10.1.0.2:9997 [tcpout:site_two_ingest] disabled=true server=10.2.0.1:9997,10.2.0.2:9997 Is there any way to configure the UFs to prefer the local Edge Processors (site_one_ingest), but then to failover to the second site (site_two_ingest) if those systems are not available? Is it also possible for the configuration to support automated failback/recovery?
