Examples

Example 1: Extract all the files generated by gpmemwatcher for the Greenplum master

Locate the output .gz file from gpmemwatcher and run gpmemreport against it:

  1. $ gpmemreport mdw.ps.out.gz
  2. >>>21:11:19:15:37:18<<<
  4. >>>21:11:19:15:38:18<<<
  6. >>>21:11:19:15:39:18<<<

Check that the generated files are listed under the current directory:

  1. $ ls -thrl
  2. -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153718
  3. -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153818
  4. -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153918

Example 2: Extract the files generated by gpmemwatcher for the Greenplum master starting after a certain timestamp

Locate the output .gz file from gpmemwatcher and run gpmemreport against it, indicating the start time as 2021-11-19 15:38:00:

  1. $ gpmemreport mdw.ps.out.gz --start='2021-11-19 15:38:00'
  2. >>>21:11:19:15:37:18<<<
  4. >>>21:11:19:15:38:18<<<
  6. >>>21:11:19:15:39:18<<<

Check under the current directory that only the selected timestamp files are listed:

  1. $ ls -thrl
  2. -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153818
  3. -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153918
