Resource Considerations

This document describes concerns and limitations to be considered when allocating resources for your a9s LogMe2 plans.

Since a9s LogMe2 includes an OpenSearch cluster (or single), all limitations for a9s Search apply to this service as well.

Dependency on Trusted Certificates

In order to be able to use the TLS syslog drain functionality and for the OpenSearch Dashboards to be reachable, you must configure either a CA or a wildcard certificate.

These certificates must be trusted by Cloud Foundry as well.

This limitation also extends to the user provided certificates as the Certificate Authority (CA) used to sign them must be trusted by Cloud Foundry.

Fluentd

Buffers

Traditionally, Fluentd has used memory buffers for buffering data. While memory buffers are fast and efficient, they come with the risk of losing data in case of a system failure. In order to mitigate this risk, we have decided to switch to file buffers.
