Description anmol babu 2017-10-13 17:34:26 UTC

Description of problem:
node-agent rpm loads tendrl-specific collectd plugins in /usr/lib/collectd whereas the collectd plugin path is /usr/lib64/collectd hence the collectd shows the error:
python plugin: Error importing module "tendrl_gluster".
Unhandled python exception in importing module: ImportError: No module named tendrl_gluster

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Import gluster cluster into Tendrl
2. Observe grafana brick dashboard

Actual results:
No collectd stats in grafana. It shows "No Datapoints"

Expected results:
All applicable stats pushed from either collectd or monitoring-integration should be available on grafana

Additional info:
node_agent rpm is installing collectd plugins at path /usr/lib/collectd instead of collectd plugin path /usr/lib64/collectd which is causing issue that our cusom collectd plugins are not pushing data to graphite.
This is possibly bcoz of difference in value of _libdir in rhel vs centos/fedora in https://github.com/Tendrl/node-agent/blob/master/tendrl-node-agent.spec#L47 of spec file. So we probably will need to hard code path as /usr/lib64/collectd in lines 47, 48 and 57 and 85.

This issue is fixed with latest builds

Comment 3 Martin Bukatovic 2018-03-13 08:21:26 UTC

Moving into right component.

Comment 8 Daniel Horák 2018-07-26 09:17:32 UTC

Collectd plugins from tendrl-node-agent package are in
/usr/lib64/collectd path:

  /usr/lib64/collectd/gluster/utils.pyo

Also there is no Import Error in the logs as described in the description and
Grafana dashboards contains the required data.

# rpm -q tendrl-node-agent 
  tendrl-node-agent-1.6.3-9.el7rhgs.noarch

NOTE: it is fixed also in the previous released version tendrl-node-agent-1.5.4-16.el7rhgs.noarch.
