For example you got a dump like this:
"MyThread" prio=1 tid=0x0850c9f8 nid=0x1baf runnable
what does the nid mean here? Is it a hex value of pid or lwpid?

Java ID (tid): the unique ID given by the JVM. Native ID (nid): the unique ID given by the OS, useful to extract correlation with CPU or memory processing. State: the actual state of the thread. Stack trace: the most important source of information to decipher what is happening with our application.
Thread id is basically a conversation id. It is assigned for a conservation (can be a group chat or one to one).
A stack trace is a user-friendly snapshot of the threads and monitors in a Virtual Machine for the Java platform (Java Virtual Machine or JVM machine). A thread dump shows what every thread in a JVM is doing at a given time and is useful in debugging.
TIMED_WAITING. The thread is waiting for another thread to perform an action for up to a specified waiting time. TERMINATED. The thread has exited.
nid is Native Thread ID : Crucial information as this native Thread Id allows you to correlate for example which Threads from an OS perspective are using the most CPU within your JVM etc.
