Enabling And Disabling The Core Dump Monitor - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

When a router uses local NVS to store a core dump, the SRP does not need the
management Ethernet port. However, because of the immense size of local core
dump files, using NVS to store core dumps is not practical.
The SRP-120 available on the E120 router and the SRP-320 available on the E120
and E320 routers has a second NVS card which is dedicated to storing core dump
files.
The core dump monitor eliminates the impact that core dumps may have on
redundant routers by allowing you to manage core dump files in NVS. The core dump
monitor allows you to automatically transfer core dump files from NVS to an FTP
server location for storage. The core dump monitor can also automatically delete
transferred core dump files.
The core dump monitor attempts to delete transferred files when all of the following
conditions have been met:
Only those core dump files that have already been transferred from NVS are
considered for deletion. Of those, the oldest files are deleted first, and the router
generates a log message for each core dump file it deletes.
NOTE: If the router NVS does not contain sufficient space to hold a new core dump
file even after deleting all possible core dump files, the core dump fails and the router
generates a log message for this condition.

Enabling and Disabling the Core Dump Monitor

The core dump monitor is disabled by default. To enable the core dump monitor,
use the exception monitor command. Use the no version of this command to disable
the core dump monitor.
exception monitor
The router attempts to write a core dump file to NVS.
NVS contains insufficient space to hold the new core dump file.
The core dump files have already been transferred from NVS to an FTP server
location using the automatic core dump monitor transfer process.
Use to enable the router core dump monitor and specify the location to which
you want the router to transfer core dump files.
To send the file to an FTP server, enter the IP address of the FTP server and the
name of the directory on the server to which the system will transfer the file.
Enabling the core dump monitor specifies that future core dump files be saved
to NVS. See "exception dump" on page 324 command for details.
Example
host1(config)#exception monitor 192.168.56.7 CORE_DUMPS
Use the no version to disable the core dump monitor.
