Hello,  
I have in auditbeat info messages very high value for reassembler\_seq\_gaps  
here is one example:  
auditbeat[560]: 2019-07-17T09:30:18.707Z INFO [monitoring] log/log.go:145 Non-zero metrics in the last 30s {"monitoring": {"metrics": {"auditd":{"reassembler\_seq\_gaps":8589934603,"received\_msgs":16327}}

Do you please know why is this value so high ? In other messages is around 3 or 4  
I am worried if I am losing some messages ?

thank you

I don't think reassembler\_seq\_gaps is a reliable metric. There's a better metric called kernel\_lost that's based on the kernel's lost metric. And there is a `userspace_lost` metric. Look for those as indicators that messages were dropped.

```auto
{"monitoring": {"metrics": {"auditd":{"kernel_lost":3494

```
