Forgot to mentioned that influx self-test produces a reasonable output too (long json list with some
metrics and timestamps) as well as there are the following lines in mgr log:

Dear Ceph users,
I am trying to enable influx plugin for ceph following http://docs.ceph.com/docs/master/mgr/influx/
but no data comes to influxdb DB. As soon as 'ceph mgr module enable influx' command is executed on
one of ceph mgr node (running on CentOS 7.4.1708) there are the following messages in
/var/log/ceph/ceph-mgr.<ceph-mgr-host>.log:

.... on so on for all 64 OSD I have in a cluster.....
'ceph osd tree' shows all OSD are up. 'ceph health' gives HEALTH_OK.
python-influxdb-5.0.0-2.el7.noarch is installed on ceph mgr node. That rpm was rebuilt from fc28 srpm.
'ceph config-key dump|grep influx' shows reasonable info:
"mgr/influx/database": "ceph_stats",
"mgr/influx/hostname": "<influxdb host>",
"mgr/influx/password": "<censored>",
"mgr/influx/ssl": "false",
"mgr/influx/username": "cephstat",
"mgr/influx/verify_ssl": "false"
influxdb-1.4.2-1.x86_64 is installed on influxdb host with CentOS 7.4.1708.
I would appreciate any help on that issue.
