Unable to connect log collector to panorama

L0 Member

I have a panorama VM running on Azure, I am currently trying to bring up some log collector VMs also on azure to handle the logs of my firewalls.


I have been able to deploy the log collectors, but when I add the log collector to the panorama through the "Managed collectors" section, I do not get any connection status, the connection status is just blank.


I can ping the IP of the log collector from the panorama and vice-versa, but I am unable to connect the log collector to the panorama.


On checking the mp.logs of the log collector, i see this error - 

Error: pan_cmsa_tcp_channel_setup(src_panos/cms_agent.c:1196): panorama agent: SSL connect error. sock=16 err=1


On checking the panorama-status on the log collector, the panorama connected state is "No"


Kindly let me know if you have seen something similar and how you fixed it.

Thank you for the post @BabajideM


could you check below points:


1.) Make sure that Log Collector's serial number and password in Panorama under Managed Log Collectors are correct.

2.) Make sure that PAN-OS of Log Collector is the same or lower than the one running on Panorama.

3.) I would also make sure that log collector is configured to use the same time zone as Panorama and that DNS server is configured:

     set deviceconfig system timezone <Time Zone>
     set deviceconfig system dns-setting servers primary <IP address> secondary <IP address>

4.) Make sure log collector is added to log collector group and push the configuration to log collector group by: Commit > Push to Devices > Collector Groups > [Log Collector name].

5.) Make sure that App content version installed on Log Collector is the same as the one on Panorama.

6.) On Panorama side, I would check the output from: show netstat numeric yes | match 3978

     Could you also take packet capture on Panorama side? You can use Log Collector's IP address as a filter. Make sure that TCP 3978 between Panorama and Log Collector are open.


Kind Regards
