Hi,

There's a Palo alto parser in the SCL that I wrote a few years back:

https://github.com/axoflow/axosyslog/blob/main/scl/paloalto/panos.conf

That parser can be used to extract the Palo fields as name value pairs.

That parser can be used to extract the .panos.device_name field, which you can then embed in your filename template as ${.panos.device_name}

To use the panos-parser() you need to include scl.conf in your main config but you probably have that already.

Let me know if it doesn't work out.

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 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
