2 Data Services
This chapter provides information about how data is handled between Oracle Communications Session Delivery Manager and your devices.
Note:
See the Configure Report Manager to Run Reports chapter for configuration information.Pushing Data to the Session Delivery Manager Server
A device pushes historical data recording (HDR) data to the configured push receiver in standard CSV format.
Report Manager periodically monitors the push receiver folder, which is configured in Report Manager, for any new data. A push receiver is an FTP or SFTP destination server to which a device pushes records. The device creates a FTP an SFTP connection to the push receiver, or server, and the CSV files are pushed to the SDM server that is running the Report Manager application. If the server is a node of an SDM cluster, device data is delivered to each member in the cluster.
Note:
If a device is removed in SDM by deleting the network function (NF) to which it belongs, you can stop the sampling and pushing of HDR data from this device to SDM by logging into the device ACLI and using the request collection stop all command.File Types and Naming Conventions
Statistical records are forwarded from the device to the SDM server for viewing in a comma-separated value (CSV) file. Before a file is pushed by the device, the device creates a directory by group name for which the statistic belongs (for example, diameter director, system, etc.), if the directory does not exist from a previous push.
Each file is formatted as
<UTC timestamp in seconds>.csv (for example, 201112250000.csv).
Each CSV file contains a record for the header containing the statistical attribute name, as well as both the push interval and collection interval records. The first record of each file is a header containing the attribute name. For example, in the “System” directory, a file name of 201112250000.csv can contain the header names of CPU Utilization, Memory Utilization, Health Score, Redundancy State, etc. Also included in the files are both the push interval and collection interval files. For example, if the collection interval is one minute, and the push interval is 15, a collection occurs every minute for 15 minutes. The CSV file in this example contains 15 records.
