Doc Type: Enhancement
Doc Text:
.`rsyslog` `mmkubernetes` now provides metadata cache expiration With this update of the `rsyslog` packages, you can use two new parameters for the `mmkubernetes` module for setting metadata cache expiration. This ensures that deleted Kubernetes objects are removed from the `mmkubernetes` static cache. The value of the `cacheentryttl` parameter indicates the maximum age of cache entries in seconds. The `cacheexpireinterval` parameter has the following values: * `-1` for disabling cache-expiration checks * `0` for enabling cache-expiration checks * greater than 0 for regular cache-expiration checks in seconds

Description Rich Megginson 2019-03-24 01:47:28 UTC
Description of problem:
mmkubernetes has a static cache - if Kubernetes objects are deleted, the cache should be cleared.  It is good enough to support a cache entry ttl as in fluent-plugin-kubernetes_metadata_filter
