Ping tool for World of Warcraft 3.3.5a servers. Correctly measures ping to servers behind a proxy.
Definitions:
Sent- number of ping requests sentConn- mean connect time to WoW server in millisecondsHand- mean handshake time with WoW server in millisecondsPing- mean ping time to WoW server in milliseconds±- mean absolute deviation ofConn,HandandPingT1- timeouts during connectionT2- timeouts during handshakeT3- timeouts during pingE- errors
See Ping process for explanation about connection, handshake and ping.
Builds are available at the Release page.
If you are interested in the WoW Circle 3.3.5a server you don't need to extract realm list - it's already included in the build. You can skip this step.
You will need to extract realm list first. Wow servers can give you realm list only after login, so you will have to enter your username and password. This project has an utility, which logins to WoW server similar real WoW game client and save realm list to servers folder.
Start realmlist.bat on Windows or realmlist on Linux. It will ask server host, your username and password.
If you worry about your credentials you can run Wireshark, login in your WoW client and extract realmlist yourself.
Simple example, which loads realm list from servers/wowcircle.json file, sends ping requests and print statistics every 10 seconds:
wow-ping.exe wowcircleYou can filter servers by regexp with -filter option:
wow-ping.exe -filter "x4" wowcircleWindows builds comes with some .bat files which you can use or make similar for you.

We suppose a WoW server can be behind a proxy or a client can use VPN. That's why a simple ICMP or TCP ping isn't enough. We need to send and recieve a packet after handshake established to measure ping correctly.
Network requests during a single ping process:
| # | Connection | Handshake | Ping |
|---|---|---|---|
| 1 | You TCP SYN → Proxy | ||
| 2 | Proxy TCP SYN-ACK → You | ||
| 3 | You TCP ACK → Proxy | ||
| 4 | Proxy TCP SYN → Server | ||
| 5 | Server TCP SYN-ACK → Proxy | ||
| 6 | Proxy TCP ACK → Server | ||
| 7 | Server SMSG_AUTH_CHALLENGE → Proxy → You |
||
| 8 | You CMSG_AUTH_SESSION → Proxy → Server |
||
| 9 | Server SMSG_AUTH_RESPONSE → Proxy → You |

Some antivirus software can detect malware (false positive) in downloaded Windows release and block download. You can add an exception and try to download it again. This tool doesn't have any malware. You can check source code and compile it yourself with golang. Also you can scan it with VirusTotal.
This tool can work as a Prometheus metrics exporter and display graphics in Grafana:
Pass the -port option:
wow-ping.exe -port 8090 wowcircleMetrics will be available at http://127.0.0.1:8090/metrics. Then you will need to setup Prometheus to grab this metrics.
