We have the pair of PA-VM deployed in HA A-P mode. The log-forwarding facility is enabled and the logs are being forwarded to the external Syslog-Server.
It is noticed that the Passive node is not sending any logs to the Syslog-Server. Only the Active node is sending the logs.
I am trying to understand that all the configurations are identical, and the communication to the Syslog-Server is directed from MGMT NIC directly to the servers on both the firewalls. So the Passive node must be sending the logs (system-log, config-log etc.).
Please let us know the behavior.
Thank you for your post @Muruganandham.SP
Since passive Firewall is not passing any traffic, you will not see any Traffic Log, Threat Log,.. etc, however System Log as well as Configuration Log will be generated and if configured correctly sent to external syslog server.
Since you mentioned that configuration is identical and active Firewall is sending logs to external syslog server as a next thing I would check settings that are not HA synchronized, for example DNS server IP address. If you have configured Syslog as FQDN make sure that passive Firewall can resolve the IP address.
Also check System logs to see any related events: ( eventid eq syslog-conn-status ).
@PavelK Yes, the Passive node cannot write any Traffic/Threat logs unless he becomes an active. So it is expected not to see Traffic/Threat logs.
The concern here is, system-log config-log etc.
Yes, we do have the proper reachability to the Syslog server, FQDN works fine, DNS settings are made correctly and works fine. HA status is 'In-Sync'.
The system-log in Passive node states that the syslog-server is 'connected' (it shows the old date though, while the Active node shows two different dates with newer date)
Thank you for quick reply @Muruganandham.SP
Sorry if I ask silly question, but based on your screen shot, the destination IP address is: 127.0.0.1 which is reserved loopback IP address. It looks like it is sending logs to itself?
