Bug reported via https://discuss.elastic.co/t/metricbeat-unable-to-ship-monitoring-information-on-windows-machine/189956.
When the
elasticsearch
module is enabled and configured withxpack.enabled: true
, thenode_stats
metricset tries to parse CPU load average from the ElasticsearchGET _nodes/_local/stats
API response. If Elasticsearch is running on Windows, no CPU load average is reported by this API. So Metricbeat currently fails with an error like this:This PR makes the parsing of CPU load average optional so we don't see this error when ES doesn't report the CPU load average, e.g. when it's running on Windows.
