Use /spark tickmonitor to Detect Lag Spikes

What Does  /spark tickmonitor Do? 

 This command tracks tick execution time and highlights spikes by comparing individual ticks against the server’s average tick duration. 

 How to Use It 

 

 

 

 Enable Monitoring Run: 

 /spark tickmonitor 

 

 By default, Spark will report ticks that take 100% longer than the average. 

 

 

 Set a Custom Threshold You can use an absolute tick duration threshold. For example: 

 /spark tickmonitor --threshold-tick 50 

 

 This will report any tick exceeding 50 milliseconds. 

 

 

 Observe Gameplay 

 

 Wait for a lag spike to occur. 

 Note the in-game effects during the spike and correlate them with the monitoring output in chat. 

 

 

 

 Adjust Sensitivity if Needed If no spikes are detected, lower the threshold: 

 /spark tickmonitor --threshold-tick 70 

 

 

 

 

 Example 

 If a WorldEdit action creates a spike, you might see ticks reported with over 1000% increases in duration.
