I work at an MSSP and am trying to get my clients Fortigate 100D to send its logs to our syslog server. The server is listening on 514 TCP and UDP and is configured to receive the logs.
FortiOS Version: 5.4.3,build 1111
The Fortigate is configured in the CLI with the following settings:
get log syslogd setting status : enable server : 10.0.0.152 reliable : disable port : 514 csv : disable facility : local0
It is configured to log all events in the GUI (Local Traffic Log and Event Logging) and the log graph shows about 100MB of logs per day.
Logs are set to be stored on the Disk, Local Reports are disabled, logs are not sent to FortiAnalyzer, and logs are sent to my customers FortiCloud account but I cannot find any documention that would say that sending them to FortiCloud would prevent them from being sent to a syslog server.
The syslog server however is not receivng the logs. Doing traffic dumps on a device with a SPAN/mirror port shows that the fortigate is not even attempting to send the logs, there is no record of any traffic going from it to the syslog server.
Is there any reason that the FortiGate will not send them? The configuration appears correct.

Everything in the GUI for Local Traffic Log and Event Logging is enabled and this is the output of the syslogd filter:
set severity information set forward-traffic enable set local-traffic enable set multicast-traffic enable set sniffer-traffic enable set anomaly enable set voip enable set filter '' set filter-type include
How would I check for having logging enabled on fw policy? I can see logs in the GUI for my account logging in and out and failed logins.
( cli )
show full firewall policy | grep-C 4 log
Also i would check if memory logging shows anything also.
( cli )
execute log filter dev ? ( select memory typically "0" )
execute log filter cat 0
execute log display
execute log filter cat 1
execute log display

I ran "show full firewall policy | grep -c 4 log" and the output was just the word "log"
For the memory logging both execute log displays returned 0 logs found and 0 logs returned
You have no firewall policy with logging on. Can you enable some high traffic fw.policy?
See this blogpost of a cli-cmd and firewall policy with logging enabled and log-start if you want to log the start of the session.
This ( log start ) will display the sessionid at the start and b4 the close action for the session.

What exactly does this do? Does the lack of a firewall policy for logging mean that is what prevents the logs from being sent?
Since this is not my firewall I just want to be careful with what I am touching. Editing a firewall policy configuration seems like a change I would want to review with my customer first.
Your goal is to check logging via syslog right ? So you need some action that raises a log event .
e.g
fw.traffic
cfg-change
user authen ( webgui/ssh )
So generate some activity and valid memory and then syslog. To handle your concerns yes a fw.policy change should be handle in a CRB settings even tho it's very low/generic in nature.
So try the following
1: make 3-6 login attempts and fail them
2: monitor the log MEMORY
3: if success , repeat but monitor SYSLOG

Just want to update this for others with the problem. Upgrading the Fortigate from 5.4.3 build 1111 to 5.6.4 build 1575 fixed the problem and syslog started sending once the update was completed.
Hi,
We have 500E FGT which we recently upgraded from 6.0.2 to 6.0.4 since then its not sending any events to the solarwinds syslog server
Below is the output of syslogd settings
status : enable server : 10.0.0.4 mode : udp port : 514 facility : local7 source-ip : format : default
I also see n numbers of packets when I run the below command
diag sniffer packet any 'dst 10.0.0.4' 4 0
when I see lem console in Solarwinds it says its not receiving logs from firewall since 10 days (basically after the upgrade date it stopped sending)
Any help is appreciated!
Thanks
