following is grep line with additional before and after line of /var/lib/mysql/7svdbm01-slow.log:

[root@7svdbm01 ~]# grep -A1 -B1 '# Time: 171227 21:31:19' /var/lib/mysql/7svdbm01-slow.log 
DELETE FROM node_revisions where vid in (SELECT vid FROM node WHERE type = '' AND uid = 0);
# Time: 171227 21:31:19
# User@Host: X[X] @ X.X.X [X.X.X.X]
[root@7svdbm01 ~]#

this is standard slow.log file, I haven't had a need to customize it anyhow...
