We have installed Metricbeat 7.1.1 on the servers in our Docker cluster and enabled the docker module with the following configuration:
- module: docker
metricsets:
- container
- cpu
- diskio
- event
- healthcheck
- info
- memory
- network
period: 10s
hosts: ["unix:///var/run/docker.sock"]
# If set to true, replace dots in labels with `_`.
#labels.dedot: false
# To connect to Docker over TLS you must specify a client and CA certificate.
#ssl:
#certificate_authority: "/etc/pki/root/ca.pem"
#certificate: "/etc/pki/client/cert.pem"
#key: "/etc/pki/client/cert.key"
...in other words, the standard docker module config, with the metricsets uncommented and enabled. However, I get the following error, and no metrics report in:
2019-07-15T08:55:44.856-0500 ERROR cpu/helper.go:143 Error calculating CPU time change for docker module: new stats value (0) is lower than the old one(20157987100000000)
When I comment out cpu from metricsets and do a restart, I don't get any errors and the metricbeat reports in as expected for the docker module.
