Hello,
After an update to version 8.4.3, I have this warning:
- regular expression has redundant nested repeat operator
I took the time to search for it, but no post was found:
- [[ES 7.6] regular expression has redundant nested repeat operator](https://discuss.elastic.co/t/es-7-6-regular-expression-has-redundant-nested-repeat-operator/220835)
- [Filebeat Elasticsearch module pipeline causing regex error on Elasticsearch cluster node · Issue #15840 · elastic/beats · GitHub](https://github.com/elastic/beats/issues/15840#issuecomment-635765482)
did not give me a solution.
My problem is more general because, I have this message and no more logs of all my integrations:
- Cisco ASA
- Auditd Logs
- etc.
So I removed the integrations, uninstalled Fleet, Elastic-Agent and reactivated Syslog-ng for my needs.
I could use some help.
I would appreciate it.
Regards,
PM75.
