Configuring HDR via the ACLI
This section provides procedures for configuring HDR. HDR configuration includes:
- setting parameters to govern sample and push intervals, and start/end times for collection
- setting parameters to support HDR across a high availability (HA) node
- setting group parameters to inform the Oracle Communications Session Border Controller (OCSBC), which groups of records to collect, when to start and stop collecting, and how often to sample for a specific group.
- setting push receivers that transport the records forwarded by the
OCSBC
Note:
If you modify the HDR configuration parameters using the ACLI, the changed parameters DO NOT take affect until you reboot the OCSBC
Enabling HDR Collection
You access the parameters that enable and support HDR using the ACLI system-config path.
To enable HDR collection:
Setting Global Collection
You access the collection configuration through the ACLI system-configuration menu. Once in the collection configuration, you can establish the global settings for HDR collection.
To set HDR global collection:
Setting HDR for an HA Node
If you are using the HDR feature on a High Availability (HA) node (or redundant pair of OCSBCs), several parameters in the collection configuration must be set for HDR to perform properly.
Oracle recommends strongly that you do not change these parameters from their defaults for a normal HA node configuration. Therefore, if you need to change them to support HDR, you should do so with caution.
To set HDR support across an HA node:
Setting Multiple Collection Groups
You can configure the OCSBC to collect multiple groups of statistics. Collection group settings are accessible through the collection configuration. For specific group names, group statistics, and values, see HDR Groups and Group Statistics.
The sample-interval, start-time, and end-time parameters that you set for multiple collection groups override the same parameters set for global collection.
Note:
For multiple collection groups, the sample-interval value must always be smaller than the global collection parameter value for push-interval.To set multiple collection groups:
Setting Servers as Push Receivers
You can configure multiple push receivers that represent FTP or SFTP destination servers for which the OCSBC pushes records. Push receiver settings are accessible through the collection configuration.
If you configure more than one server, the OCSBC sends data to all of the servers. If one server fails, the OCSBC generates an SNMP trap. The OCSBC makes 3 attempts to send data to the failed server. If the server cannot receive the data, the OCSBC clears the data for that server. For example, if there are four servers configured, and the OCSBC successfully pushes data to three of them, the OCSBC generates a trap indicating the fourth server is down and after 3 attempts to send the data, the data is cleared.
To set servers as push receivers:
