Adding this after the pam decoder seems to work for me (but I haven't made sure nothing else breaks): <decoder name="pam-ssh"> <parent>pam</parent> <prematch>^pam_unix\(sshd:\w+\): </prematch> <regex offset="after_prematch">^session \w+ for user (\S+) </regex> <order>user</order> </decoder> > 2018-11-16 00:05:02,134 Detector [WARNING]: ssh[4003] Event's field dst_ip > pds2 is not a valid IP.v4/IP.v6 address, falling back to default: 0.0.0.0 > > 2018-11-16 00:05:02,135 Detector [WARNING]: ssh[4003] Event's device field > pds2 is not a valid IP.v4/IP.v6 address, falling back to default local. > There's no decoder for these at all.
