Guru Meditation Reports
=========================
A Guru Meditation Report (GMR) is generated by the Designate services when
service processes receiving SIGUSR2 signal. The report is a general-purpose
debug report for developers and system admins which contains the current state
of a running Designate service process.
Structure of a GMR
==================
Package
Shows information about the package to which this process belongs, including
version information
Threads
Shows stack traces and thread ids for each of the threads within this process
Green Threads
Shows stack traces for each of the green threads within this process (green
threads don't have thread ids)
Processes
Shows information about this process, including pid, ppid, uid and process
state
Configuration
Lists all the configuration options currently accessible via the CONF object
for the current process
Generate a GMR
==============
A GMR can be generated by sending the USR2 signal to any Designate processes.
For example, suppose ``designate-central`` has pid ``15097``, ``kill -USR2
15097`` will trigger a GMR.
If option ``logdir`` has been set in ``designate.conf``, the GMR will be saved
in the folder which ``logdir`` specified. Otherwise, the GMR will be printed to
the stderr.
Reference
=========
For more information about GMR, see `GMR wiki`_.
