Logging 5.7

Before this update, there was a potential conflict when the same name was used for the outputRefs and inputRefs parameters in the ClusterLogForwarder custom resource (CR). As a result, the collector pods entered in a CrashLoopBackOff status. With this update, the output labels contain the OUTPUT_ prefix to ensure a distinction between output labels and pipeline names. (LOG-4383)

Before this update, while configuring the JSON log parser, if you did not set the structuredTypeKey or structuredTypeName parameters for the Cluster Logging Operator, no alert would display about an invalid configuration. With this update, the Cluster Logging Operator informs you about the configuration issue. (LOG-4441)

Before this update, if the hecToken key was missing or incorrect in the secret specified for a Splunk output, the validation failed because the Vector forwarded logs to Splunk without a token. With this update, if the hecToken key is missing or incorrect, the validation fails with the A non-empty hecToken entry is required error message. (LOG-4580)

Before this update, selecting a date from the Custom time range for logs caused an error in the web console. With this update, you can select a date from the time range model in the web console successfully. (LOG-4684)

CVE-2023-40217

CVE-2023-44487

Before this update, there was an error in the query used for the FluentD Buffer Availability graph in the metrics dashboard created by the Cluster Logging Operator as it showed the minimum buffer usage. With this update, the graph shows the maximum buffer usage and is now renamed to FluentD Buffer Usage. (LOG-4555)

Before this update, deploying a LokiStack on IPv6-only or dual-stack Red Hat OpenShift Service on AWS clusters caused the LokiStack memberlist registration to fail. As a result, the distributor pods went into a crash loop. With this update, an administrator can enable IPv6 by setting the lokistack.spec.hashRing.memberlist.enableIPv6: value to true, which resolves the issue. (LOG-4569)

Before this update, the log collector relied on the default configuration settings for reading the container log lines. As a result, the log collector did not read the rotated files efficiently. With this update, there is an increase in the number of bytes read, which allows the log collector to efficiently process rotated files. (LOG-4575)

Before this update, the unused metrics in the Event Router caused the container to fail due to excessive memory usage. With this update, there is reduction in the memory usage of the Event Router by removing the unused metrics. (LOG-4686)

Before this update, it was not possible to delete the openshift-logging namespace directly due to the presence of a pending finalizer. With this update, the finalizer is no longer utilized, enabling direct deletion of the namespace. (LOG-3316)

Before this update, the run.sh script would display an incorrect chunk_limit_size value if it was changed according to the Red Hat OpenShift Service on AWS documentation. However, when setting the chunk_limit_size via the environment variable $BUFFER_SIZE_LIMIT, the script would show the correct value. With this update, the run.sh script now consistently displays the correct chunk_limit_size value in both scenarios. (LOG-3330)

Before this update, the Red Hat OpenShift Service on AWS web console’s logging view plugin did not allow for custom node placement or tolerations. This update adds the ability to define node placement and tolerations for the logging view plugin. (LOG-3749)

Before this update, the Cluster Logging Operator encountered an Unsupported Media Type exception when trying to send logs to DataDog via the Fluentd HTTP Plugin. With this update, users can seamlessly assign the content type for log forwarding by configuring the HTTP header Content-Type. The value provided is automatically assigned to the content_type parameter within the plugin, ensuring successful log transmission. (LOG-3784)

Before this update, when the detectMultilineErrors field was set to true in the ClusterLogForwarder custom resource (CR), PHP multi-line errors were recorded as separate log entries, causing the stack trace to be split across multiple messages. With this update, multi-line error detection for PHP is enabled, ensuring that the entire stack trace is included in a single log message. (LOG-3878)

Before this update, ClusterLogForwarder pipelines containing a space in their name caused the Vector collector pods to continuously crash. With this update, all spaces, dashes (-), and dots (.) in pipeline names are replaced with underscores (_). (LOG-3945)

Before this update, the log_forwarder_output metric did not include the http parameter. This update adds the missing parameter to the metric. (LOG-3997)

Before this update, when configuring log forwarding to write to a Kafka output topic which matched a key in the payload, logs dropped due to an error. With this update, Fluentd’s buffer name has been prefixed with an underscore, resolving the issue.(LOG-4027)

Before this update, the LokiStack gateway returned label values for namespaces without applying the access rights of a user. With this update, the LokiStack gateway applies permissions to label value requests, resolving the issue. (LOG-4049)

Before this update, the Cluster Logging Operator API required a certificate to be provided by a secret when the tls.insecureSkipVerify option was set to true. With this update, the Cluster Logging Operator API no longer requires a certificate to be provided by a secret in such cases. The following configuration has been added to the Operator’s CR:

tls.verify_certificate = false
tls.verify_hostname = false

Before this update, the LokiStack route configuration caused queries running longer than 30 seconds to timeout. With this update, the LokiStack global and per-tenant queryTimeout settings affect the route timeout settings, resolving the issue. (LOG-4052)

Before this update, a prior fix to remove defaulting of the collection.type resulted in the Operator no longer honoring the deprecated specs for resource, node selections, and tolerations. This update modifies the Operator behavior to always prefer the collection.logs spec over those of collection. This varies from previous behavior that allowed using both the preferred fields and deprecated fields but would ignore the deprecated fields when collection.type was populated. (LOG-4185)

Before this update, the Vector log collector did not generate TLS configuration for forwarding logs to multiple Kafka brokers if the broker URLs were not specified in the output. With this update, TLS configuration is generated appropriately for multiple brokers. (LOG-4163)

Before this update, the option to enable passphrase for log forwarding to Kafka was unavailable. This limitation presented a security risk as it could potentially expose sensitive information. With this update, users now have a seamless option to enable passphrase for log forwarding to Kafka. (LOG-3314)

Before this update, Vector log collector did not honor the tlsSecurityProfile settings for outgoing TLS connections. After this update, Vector handles TLS connection settings appropriately. (LOG-4011)

Before this update, not all available output types were included in the log_forwarder_output_info metrics. With this update, metrics contain Splunk and Google Cloud Logging data which was missing previously. (LOG-4098)

Before this update, when follow_inodes was set to true, the Fluentd collector could crash on file rotation. With this update, the follow_inodes setting does not crash the collector. (LOG-4151)

Before this update, the Fluentd collector could incorrectly close files that should be watched because of how those files were tracked. With this update, the tracking parameters have been corrected. (LOG-4149)

Before this update, forwarding logs with the Vector collector and naming a pipeline in the ClusterLogForwarder instance audit, application or infrastructure resulted in collector pods staying in the CrashLoopBackOff state with the following error in the collector log:

ERROR vector::cli: Configuration error. error=redefinition of table transforms.audit for key transforms.audit

Before this update, when forwarding logs to a syslog destination with the Vector collector and setting the addLogSource flag to true, the following extra empty fields were added to the forwarded messages: namespace_name=, container_name=, and pod_name=. With this update, these fields are no longer added to journal logs. (LOG-4219)

Before this update, when a structuredTypeKey was not found, and a structuredTypeName was not specified, log messages were still parsed into structured object. With this update, parsing of logs is as expected. (LOG-4220)
