How to Monitor Server Uptime and Load

Track your server's availability and performance metrics.

Check Uptime

uptime

Output: 10:30:00 up 45 days, 3:12, 1 user, load average: 0.15, 0.10, 0.05

Understanding Load Average

The three numbers represent load over 1, 5, and 15 minutes:

• 1-core server: load of 1.0 = 100% utilized
• 2-core server: load of 2.0 = 100% utilized
• 4-core server: load of 4.0 = 100% utilized

Load above the number of cores means processes are queuing.

Continuous Monitoring

# Watch load every 2 seconds\nwatch -n 2 uptime\n\n# Historical with sar\napt install sysstat -y\nsar -q 1 10
