Hi Cephers,
What is the tracing tool used normally to trace the internal latency for each function and locks in Ceph?
I’m trying to trace the whole path for each object. Perf counter works for me, but I want to have a secondary
tool to help me verify my observations.
Please advice.
Thank,
Yiming
Hi,
*PLEASE HELP ME IN THIS ....still waiting for the reply !*
I am using Ceph developer mode in my virtual machine. I have Ceph in my
*/home/user. *I have clone the repository. Then downloaded the build code
dependencies using* ./install-deps.sh* . Then compiled and buld. I start
in developer mode with *make vstart *and* MDS=0 RGW=1 ../src/vstart.sh -d
-l -n --bluestore. *Works all fine ! I can write a test data to the
cluster.
The problem is, my home disk space utilization is increasing. What could
be the problem? Is it the cluster in developer mode taking up the home
space? Are there some logs being generated?
Please Looking for help /suggestions

Hi all,
I'm trying to build ceph/master with enabling "-DWITH_SEASTA=ON"
It always failed at missing lksctp-tools when builing ceph/master with enabling "DWITH_SEASTAR=ON"
Does anyone know how to solve the problem?

Im trying to understand how to configure the ceph-mgr restful plugin module
for Mimic (13.2.8).
Some docs (maybe out of date) seem to indicate that the base url for the
api is "/api/v0.1", but ours seems to be using just "/api".
There used to be a configuration parameter "restapi_base_url", but
apparently that is not supported anymore.
My question - What is the base URL for the mgr restful module and is it
configurable?
There are some packages (such as the elasticsearch metricbeat ceph module)
that have hard coded "/api/v0.1" as the base URL and wont work with newer
ceph releases if that URL doesn't work.
thanks,

Hi all,
where in the code does it generate the ceph.conf file? and also where does it fill the osd sections?
I could not find it in the code under master. maybe I was looking in the wrong directory.
I want to write a patch that doesn't write all the osd information in this file for some hosts.
Thanks
