    Release Information

    Statement introduced in Junos OS Mobility Release 11.2W.


    Configure the percentage of RE disk space to be used for storage and also the action to be taken when this limit is reached, such as raise snmp-alarms, record the alert information in the system logs, or do both.

    When this watermark level is reached, the Charging daemon stops writing the CDRs to the local RE disk till the CDR storage space is restored by transferring the files via SFTP and deleting the files from the CDR log directory. However, the data is not immediately lost because the Service PICs buffer up to 2 GB of data.


    notification-level (both | snmp-alarm | syslog)—Specify whether you want to raise snmp alarms or log information on the system logs, or do both when the watermark level is reached.

    • both—Log the alert information on system log files and also raise an snmp alarm.
    • snmp-alarm—Raise an snmp alarm.
    • syslog—Log the alert information on system log files.

    Default: syslog

    percentage value—The percentage of RE disk space to be used for storage after which you get an alert (if it is configured).

    Default: 90% of the RE disk space
