To prevent excessive memory usage, the metric data exported by the OpenTelemetry collector is no longer written to the tmp directory.
Instead, it is now stored in the var directory.
This change helps to avoid memory pressure that can occur when using tmpfs for large data exports.
The data has been moved from:
<site_path>/tmp/check_mk/otel_collector/host_monitoring
to:
<site_path>/var/check_mk/otel_collector/host_monitoring
