I am unable to list the locks associated with a process and information about the locks i.e How many threads share this lock etc.

Kindly tell my how to extract this information from a process ID.

My case:

i have run sysbench command

sysbench --test=threads --thread-locks=100 --max-time=20s run

i want to list locks that sysbench just created and information about the locks i.e which threads the sharing this lock etc

If you're talking about file locks,

lsof -p PID

will list all files opened by process with PID.

lsof -c processname

will list all files opened by processname.

Note that lsof lists also files opened only for read i.e. without file locks. The mode under which a file is open is specified as the fourth character in the FD (File Descriptor) column in the output:

 r for read access;
 w for write access;
 u for read and write access;
 space if mode unknown and no lock
 character follows;
 `-' if mode unknown and lock
 character follows.
