RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: rsyslog-8.1911.0-1.el8
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
