Greetings to the community, I would like to better understand what you mean by transmit errors in a firewall interface. I have a case in a firewall where I had increases in transmit errors and I would like to know why. Thank you so much
Bear in mind SolarWinds is only reporting what the node is passing to it.That said, it would be helpful if you tell us what type of firewall (male/model) as it could make a difference. Generically speaking though, transmit errors are typically due to "noise". Said noise can be caused by any number of factors from a dodgy PSU, power lines, attenuation, etc
Thank you for your prompt response, the equipment is a Fortigate fgt1100E, and that information that you see is a VPN that is connected to said firewall, I would like to know if it is a transmission error on the part of the VPN or on my side. Thank you
You'd need to investigate the firewall for that info. Try these as a starter: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Troubleshooting-IPsec-VPN-tunnel-errors-with-large/ta-p/194539 - or - https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-IPsec-VPNs-tunnels/ta-p/195955
ok, but in that perfstack graph, the blue transmit error line refers to a variation of the VPN towards me or from my side towards the VPN. It is to understand the graph, then I would go more in detail to the firewall
What is reporting those peaks of the blue line that tells me transmit errors
I don't know that - you'd need to investigate the firewall to see what it is reporting. You could potentially do tcpdump or wireshark capture to determine what is 'peaking' - and then extrapolate form there.
If you are asking what OID is being reported on, then I don't have that answer. Raising a ticket with support may get you that answer.
Actually it is that, knowing how to interpret the graph. Then it tells you that there were transmitted errors but only informative, on which side were the errors, there you would have to go to the firewall
