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:
$ gpmemreport mdw.ps.out.gz >>>21:11:19:15:37:18<<< >>>21:11:19:15:38:18<<< >>>21:11:19:15:39:18<<<
Check that the generated files are
listed under the current directory:
$ ls -thrl -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153718 -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153818 -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:
$ gpmemreport mdw.ps.out.gz --start='2021-11-19 15:38:00' >>>21:11:19:15:37:18<<< >>>21:11:19:15:38:18<<< >>>21:11:19:15:39:18<<<
Check under the current directory that only the selected timestamp files are
listed:
$ ls -thrl -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153818 -rw-rw-r--. 1 gpadmin gpadmin 1.2K Nov 19 15:50 20211119-153918
