sysmon-config VS ThreatHunting

https://learn.microsoft.com/en-us/troubleshoot/windows-client/networking/networking-overview plenty of windows troubleshooting tips here too, and this is pretty good symon script saves to event viewer even after a reboot! , also care with wireshark as it may give you a false sense of there's a fault, try tcpIPview from sysinternals and yeah procmon for sure. https://github.com/SwiftOnSecurity/sysmon-config use psping to ping the server directly and see the latency goes up and down, you can ping it more often every 1 second so you get a better more detailed resul.

Rebooted and downloaded sysmon 14.16 and sysmonconfig-export.xml

There's all sorts of things you can do for various types of monitoring including Zabbix, Graylog, roll-your-own with Sysmon (see https://github.com/SwiftOnSecurity/sysmon-config), etc. The question becomes one of time - don't get so focused on DIY or free that you spend hours (or pay someone to spend hours) a month babysitting.

If you don't catch it what changes can you do to your logging to enable it? Can you push it out to the environment? While sysmon is awesome, you can do your hunts with built in logging most of the time... Just might not have all the data around it you want to have. I would throw sysmon on a test box (make sure you have a config file that filters out the noise: https://github.com/SwiftOnSecurity/sysmon-config)

I played around with https://github.com/SwiftOnSecurity/sysmon-config Maybe there xml can point you in the right direction

and here's an off the shelf config file: https://github.com/SwiftOnSecurity/sysmon-config

- Make sure you have sysmon installed on the agent host and it is logging event to the Sysmon folder as ID 22. Can use this xml file

Out of our 286 Windows Servers, this single server did not like our sysmon config file from SwitfOnSecurity - https://github.com/SwiftOnSecurity/sysmon-config/blob/master/sysmonconfig-export.xml
