I installed metricbeat 6.7 on my RHEL 7 machine and when I tried to open the default metricbeat dashboard on kibana, it doesn't show any data except the one below
Parts of or the entire area chart might not be displayed due to null values in the data. A line chart is recommended when displaying data with null values.
or blank chart or no results found
Elasticsearch and kibana installed on RHEL7 are of 6.7 version.
Please note Metricbeat setup did not error out.
