Fixed In Version: ceph-17.2.3-29.el9cp
Doc Type: Bug Fix
Doc Text:
.The `ceph daemon heap stats` command now returns required usage details for daemon Previously, the `ceph daemon osd.x heap stats` command would return empty output instead of the current heap usage for a ceph daemon. Consequently, users were compelled to use the `ceph tell heap stats` command to get the desired heap usage. With this fix, the `ceph daemon heap stats` command returns heap usage information for a Ceph daemon similar to what we get using `ceph tell` command.
