We are having issues with a OPSEC LEA connector. The Checkpoint firewall is showing say 5,000,000 events per hour.
Using Metrics from Splunk;
index=_internal host="splunk-fwd-1 component=Metrics
| stats sum(ev) as Total
| eval Total_Events=round(Total)
| fields - Total
| fieldformat Total_Events=tostring(Total_Events,"commas")
Shows 5,500,000 events for the time frame process by the forwarder.
Using TSTATS;
| tstats count where index=checkpoint by host,_time span=1m
| search splunk_forwarder=splunk-fwd-1
| chart sum(count) AS Total_Event_Count
| fieldformat Total_Event_Count=tostring(Total_Event_Count,"commas")
Shows 3,000,000 events for the time frame indexed
Where are the events? We see that using index data that the event count vs what is seen on the firewall is significant less than expected. Even if we go back say a month, it isn't like the events are delay coming in. Are we really losing 2 million events per hour?
