本文介绍 Erlang 的 etop 监控工具使用方法，展示如何查看节点负载、进程数、就绪队列长度及内存使用情况等关键指标。同时，还详细解释了如何获取每个进程的运行时间、已执行的缩减次数、内存占用大小及其消息队列长度。
摘自官方文档：http://www.erlang.org/documentation/doc-5.2/lib/observer-0.9/doc/html/etop_ug.html
The header includes some system information:
-
Load
-
cpuisRuntime/Wallclock, i.e. the percentage of time where the node has been active,procsis the number of processes on the node, andrunqis the number of processes that are ready to run.
Memory
- This is the memory allocated by the node in kilo bytes.
For each process the following information is presented:
-
Time
- This is the runtime for the process, i.e. the actual time the process has been scheduled in. Reds
- This is the number of reductions that has been executed on the process Memory
-
This is the size of the process in
bytes, obtained by a call to
process_info(Pid,memory).
MsgQ
- This is the length of the message queue for the process.
 | Time and Reds can be presented as accumulated values or as values since last update. |
