Hi All, I have a panorama system that sends logs from several devices (dvc_name). What I want to do is have it write to files based on the dvc_name. The dvc_name is in the following message as "ip-10-37-12-142". These are not static as they are spun up as needed and the dvc_name may change. Can you help me figure out how to create a parser or filter to take the following message, where it will read in the dvc_name "ip-10-37-12-142" and write logs that include that dvc_name to a separate file (and other dvc_names it sees in messages to their own file?: *Jun 27 19:08:15 TERL-PANORAMA-01.times.com <http://terl-panorama-01.times.com/> 1,2024/06/27 15:08:14,005655000463255,SYSTEM,dhcp,2817,2024/06/27 15:08:09,,if-renew-trigger,,0,0,general,informational,"DHCP RENEW: interface eth0, ip 10.37.12.142 netmask 255.255.255.224 dhcp server: 10.37.12.129",7383625404611793457,0x8000000000000000,0,0,0,0,,ip-10-37-12-142,0,0,2024-06-27T15:08:09.224-04:00* I've tried a few different things but can't figure out how to do it dynamically. This rewrite worked, but it requires a static entry which won't scale and all potential dvc_names cannot be known: rewrite r_panorama { set("ip-10-37-12-142", value("HOST") condition(message(".*ip-10-37-12-142"))); }; I've also tried creating a filter, but it doesn't actually store what the match finds in a macro that I can replace something like $HOST with. filter f_panorama { match("ip-\d+-\d+-\d+-\d+" value("MESSAGE")); }; I was also thinking that I could do something with the csv parser, but it didn't work like I was expecting, but am thinking a parser might work if I could get it right (I think partially it doesn't work because it is a syslog message and the first part of the message interferes with the csv parsing, not sure): parser p_panorama { csv-parser( columns("future_use1","receive_time","serial_number","log_type","log_subtype","version","generated_time","vsys","event_id","object","future_use3","future_use4","module","severity","description","sequence_number","action_flags","devicegroup_level1","devicegroup_level2","devicegroup_level3","devicegroup_level4","vsys_name","dvc_name") delimiters(",") quote-pairs('""[]') ); }; destination d_panorama {file("`mypath`/panorama/$dvc_name/$dvc_name.log"); }; log { source(s_panother); parser(p_panorama); destination(d_panorama); }; Is this something someone could help me with? Thank you, John
