features:
|
|
- |
|
|
Adds support for passing extra runtime options to cAdvisor via
|
|
``prometheus_cadvisor_cmdline_extras`` new variable. By default
|
|
system cgroups' metrics are disabled, plus container labels
|
|
don't get exposed to Prometheus. Expensive metrics that usually
|
|
should not be exported are also enforced to be disabled - consult
|
|
`<https://github.com/google/cadvisor/blob/master/docs/runtime_options.md#metrics>`_
|
|
for a list. These defaults create savings in resources usage by both
|
|
cAdvisor and Prometheus.
|
|
upgrade:
|
|
- |
|
|
cAdvisor has now reduced number of Prometheus metrics and labels
|
|
exported by default. This means that corresponding timeseries will
|
|
no longer be created. If existing setup relies on these, e.g. for
|
|
visualisation or alerting, they could be explicitly enabled prior to
|
|
upgrading with the ``prometheus_cadvisor_cmdline_extras`` new variable.
|
|
