Description Lubos Trilety 2017-11-20 09:28:14 UTC

Description of problem:
cephmetrics-ansible playbook.yml does not install required packages on machines, where ceph iSCSI gateways are. 

Version-Release number of selected component (if applicable):
cephmetrics-ansible-1.0-7.el7cp.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare some ceph cluster with iSCSI gateways
2. Try to install ceph-metrics
3.

Actual results:
ceph-metrics is installed however ceph iSCSI gateway machines are not monitored as no cephmetrics packages are installed on them.

Expected results:
ceph-metrics is working and 'iSCSI Overview' dashboard in Grafana shows correct data.

Hi guys,

The issue seems to be that cephmetrics-ansible is expecting a [iscsis] section in ansible inventory file while the RHCS block device guide states this section should be called [iscsigws]. Adding a [iscsis] section is enough to have the prometheus-node-exporter package correctly installed on iSCSI targets and metrics recorded and exposed on iSCSI Grafana dashboards.

You can refer to these 2 commits from Zack:
https://github.com/ceph/cephmetrics/commit/a99fdea00f19bedb8093484330a34619d7e682dd
https://github.com/ceph/cephmetrics/commit/9b5dafd45d22769fb6c33a93df2d31d363d6c673

And the RHCS block device guide:

Regards,
Frédéric.
