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.
