Fortigate not parsing cfgattr

[tnxtr]

Hi Folks,

The default parser in Google SecOps (Chronicle) does not parse attributes inside cfgattr= (such as uuid, status, name, comments) from FortiGate firewall logs. In statedump, it extracts cfgattr but I couldn't map these to udms.

Using Grok Debugger, I created a parser that correctly extracts these attributes and maps them to the appropriate UDM fields. 

I would appreciate your support in troubleshooting this issue.

%{DATA}cfgattr="uuid\[%{UUID:uuid}\]status\[%{WORD:status}->%{WORD:status_new}\]name\[%{DATA:name}\]srcaddr\[%{DATA:srcaddr_old}->%{DATA:srcaddr_new}\]schedule\[%{DATA:schedule_old}->%{DATA:schedule_new}\]comments\[%{DATA:comments_old}->%{DATA:comments_new}\]"

Hi @tnxtr ,

We noticed something similar internally and the parser team released an update on 2025-01-20 to resolve. Please ensure you're using the latest version of the parser for FORTINET_FIREWALL. See https://cloud.google.com/chronicle/docs/ingestion/parser-list/fortinet-firewall-changelog for details.

If you're still seeing this issue, please file a support ticket.

Thanks!

Yeah updated parser is worked but It did not extract the values inside; it only extracted the entire block

this is how it looks on udm;

additional.fields["cfgattr"]: "uuid[c11fdabe-c321-34df-b918-ad6661291c10]status[disable->enable]name[->Ticket-121212]srcaddr[Group_Name_1 Group_Name_2->Group2_Test_10.10.10.10 Group2_Test_10.10.10.10]schedule[always->22feb]comments[ (Rulename)->Ticket-131313]"

but i need attributes inside of cfgattr

I see! I passed your request to the parsing team for evaluation.

Thanks 🙂 I'll wait for the update
