why not use collectd? centos7 rpms  should do fine.
Marc, sorry I somehow missed your question. One of the reason could be that collectd is a additional daemon whereas influx plugin for ceph is just an additional part of the already running system (ceph).

In our case I think we grabbed the SRPM from Fedora and rebuilt it on
Scientific Linux (another RHEL derivative).  Presumably the binary
didn't work or I would have installed it directly.  I'm not quite sure
why it hasn't migrated to EPEL yet.

I haven't tried the SRPM for latest releases, we're actually quite far
behind the current python-influx version since I built it a while back
but if I were you I'd grab whatever SRPM gets you the latest
python-influxdb release and give it a try.

thanks,

Dear all,

I'd like to store ceph luminous metrics into influxdb. It seems like influx
plugin has been already backported for lumious:
rpm -ql ceph-mgr-12.2.2-0.el7.x86_64|grep -i influx
/usr/lib64/ceph/mgr/influx
/usr/lib64/ceph/mgr/influx/__init__.py
/usr/lib64/ceph/mgr/influx/__init__.pyc
/usr/lib64/ceph/mgr/influx/__init__.pyo
/usr/lib64/ceph/mgr/influx/module.py
/usr/lib64/ceph/mgr/influx/module.pyc
/usr/lib64/ceph/mgr/influx/module.pyo

So following http://docs.ceph.com/docs/master/mgr/influx/ doc I enabled
influx plugin by executing the following command on mgr node:
ceph mgr module enable influx

but in ceph log I see the following error:
2018-02-12 15:51:31.241854 7f95e7942600  0 ceph version 12.2.2

Indeed there is no python-influxdb module install on my mgr node (CentOS 7
x64) but yum search can't find it with the following repos enabled:
repo id
repo name                   status
Ceph/x86_64
Ceph packages for x86_64
Ceph-noarch
Ceph noarch packages
base/7/x86_64 CentOS-7 - Base
ceph-source
Ceph source packages
epel/x86_64
Extra Packages for Enterprise Linux 7 - x86_64
extras/7/x86_64 CentOS-7 - Extras
updates/7/x86_64 CentOS-7 - Updates

Python version is 2.7.5.

Is 'pip install' the only way to go or there is still some option to have
required python module via rpm? I wonder how other people deals with that
issue?
