Storage runtime configuration

IngressDebugExpiration

Required

string

Sets the date and time when debugging should be disabled. If you specify a future date and time, incoming OMF (Open Message Format) messages are logged and the HTTP request and response content is stored to disk for review. The debug logging stops at the date and time specified. Set the value to null to disable logging.

Every incoming OMF (Open Message Format) message logs a request and response log file. Log files are located in C:\ProgramData\OSIsoft\EdgeDataStore\Logs\IngressDebugLogs\ and grouped by the associated OMF (Open Message Format) message type. Each log file name is in the format: {ticks}-{operationId}-{Request/Response}.txt.

Valid formats are UTC (Coordinated Universal Time): yyyy-mm-ddThh:mm:ssZ and Local: mm-dd-yyyy hh:mm:ss.

When you activate logging, the content of an incoming OMF (Open Message Format) message, including the headers, is written to multiple files in the Logs directory. Those files are written to the IngressDebugLogs directory in the usual logs directory for every incoming OMF (Open Message Format) type, container, and data message.

StreamStorageLimitMb

Required

integer

The maximum size in megabytes that a stream can reach. When a stream exceeds the specified size, older data is deleted from the file until the stream is at or below the StreamStorageTargetMb value. The target value, set in the StreamStorageTargetMb property, needs to be smaller than the maximum specified in this property.

Note: EDS (Edge Data Store) must be restarted for changes to this setting to take effect.

Minimum value: 2.

Maximum value: 2147483647.

StreamStorageTargetMb

Required

integer

The size in megabytes that a stream will be reduced to after StreamStorageLimitMb size is reached for a single stream. When a stream exceeds the size specified in the StreamStorageLimitMb property, older data is deleted from the file until the stream is at or below the StreamStorageTargetMb value. The target value needs to be smaller than the maximum specified in the StreamStorageLimitMb property.

Note: EDS (Edge Data Store) must be restarted for changes to this setting to take effect.

Minimum value: 1.

Maximum value: 2147483647.

TransactionLogLimitMB

No

integer

Maximum size in megabytes for transaction log file. When a transaction log exceeds this size, it is deleted, which reduces the amount of data that you can recover if the host device loses power.

Minimum value: 1.

Maximum value: 2147483647.

CheckpointRateInSec

No

integer

Defines, in seconds, how often the storage component ensures recent data and configuration changes are flushed to storage. A setting of 0 disables checkpointing. Disabling checkpointing reduces the resiliency of the product, which can result in data loss if the host device loses power.

Minimum value: 0.

Maximum value: 86400.

EnableMetrics

No

Boolean

Enables EDS (Edge Data Store) to create a new stream in the diagnostics namespace to track some metrics about internal storage operations. These metrics have no value outside of troubleshooting specific issues with the help of Technical Support. This should be set to false unless directed by AVEVA support.

SdsLogLevel

No

reference

Restricts the logging generated by EDS (Edge Data Store) ’s internal Sequential Data Store (SDS (Sequential Data Store)) component to the provided level. Defaults to “Warning”. See log levels for valid levels. Note that this setting applies in conjunction with the overall Storage log level and only applies if it is more restrictive

StreamCacheSize

No

integer

The count of streams that will be cached in memory by the storage component. Creating more streams than this count will negatively impact performance.

Note: EDS (Edge Data Store) must be restarted for changes to this setting to take effect.

Default: 5000.
