Fixed In Version: ceph-16.2.10-119.el8cp
Doc Type: Bug Fix
Doc Text:
.The `ceph daemon heap status` command shows the heap status Previously, due to a failure to get heap information through the `ceph daemon` command, the `ceph daemon heap stats` command would return empty output instead of returning current heap usage for a Ceph daemon. This was because `ceph::osd_cmds::heap()` was confusing the `stderr` and `stdout` concept which caused the difference in output. With this fix, the `ceph daemon heap stats` command returns heap usage information for a Ceph daemon similar to what we get using the `ceph tell` command.

Description Prashant Dhange 2022-08-17 14:32:43 UTC 
Description of problem:
While fetching heap stats/dump through ceph daemon command, we are neither getting heap command output or error message. This issue has affected both OSD and MDS daemons. 

It seems all RHCS 5 versions are affected by this bug

Version-Release number of selected component (if applicable):
ceph version 16.2.7-98.el8cp

How reproducible:
Frequently

Steps to Reproduce:
1. Deploy RHCS 5.x cluster
2. Get heap dump using ceph daemon command
$ ceph daemon osd.x heap stats
3. Observe empty heap stats output

Actual results:
ceph daemon heap command fail to provide desired output

Expected results:
ceph daemon heap command should output heap stats/dump details
