Description Shirly Radco 2017-06-08 06:57:22 UTC

Description of problem:
The collectd swap plugin reports records but the collectd.swap.swap and collectd.swap.swap_io do not contain value when we inspect the data in Kibana.

Version-Release number of selected component (if applicable):
1.0.3

How reproducible:


Steps to Reproduce:
1.Setup engine and hosts
2.Setup the metrics store
3.Install metrics+logging on engine and hosts
4.Filter by collectd.plugin=swap in Kibana
5.Check the value of the collectd.swap.swap and collectd.swap.swap_io fields

Actual results:
The collectd.swap.swap and collectd.swap.swap_io are3 empty

Expected results:
The fields should show the swap actual value

Comment 1 Shirly Radco 2017-06-13 07:37:50 UTC

This was found as a more general problem. 
It seems that the  fluent-plugin-viaq_data_model removes the numeric value for records that contain only one value. 
This needs further investigation.
I asked Rich Megginson to check the plugin.

Comment 2 Rich Megginson 2017-06-13 15:00:22 UTC

This is a bug in the viaq plugin: https://github.com/ViaQ/fluent-plugin-viaq_data_model/pull/5
