Pull Request Overview

This PR fixes compatibility issues with the uptime command on certain Linux distributions (specifically openSUSE) by replacing the uptime -s command with a more portable alternative that reads from /proc/stat to get the system boot time.

Replaces uptime -s command with /proc/stat parsing approach for better OS compatibility
Improves error logging by including the exception details

tested on ubuntu 24 and rocky8, got same results as uptime -s

weizhouapache · 2025-09-18T10:05:30Z

server/src/main/java/com/cloud/server/StatsCollector.java

-                String bootTime = Script.runSimpleBashScript("uptime -s");
-                SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss", Locale.ENGLISH);
+                String bootTime = Script.runSimpleBashScript("date -d @$(grep btime /proc/stat | awk '{print $2}') '+%Y-%m-%d %H:%M:%S'");
+                SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.ENGLISH);


yyyy-MM-dd HH:mm:ss is correct I think.

yyyy-MM-dd hh:mm:ss seems wrong, did it work in the past ?

I tested locally and the old one seems to work fine as well. But as per java docs, it should be HH instead of hh.
