Description

In Juniper Device Manager (JDM), the show system core-dump command lists the core dump files, but it is not clear where these files are located. This article explains where these files are located and how to find them.

Symptoms

The request support information local command on the JDM lists the core dump files as follows: 

root@jdm> show system core-dumps 
/var/tmp/corefiles/*core* :
-rw-r--r-- 1 root root 3179805 Jun 21 16:06 ipsec-nm.srxpfe.95.1529597202.core.tgz
-rw-r--r-- 1 root root 1694150 Mar  1 16:46 jdm.jdmd.2328.1519922794.core.tgz
-rw-r--r-- 1 root root  230992 May  3 17:06 jdm.mgd.2426.1525367185.core.tgz
-rw-r--r-- 1 root root  435750 Feb 23 20:17 localhost.named.3666.1519417037.core.tgz
-rw-r--r-- 1 root root  434369 Feb  2 20:50 localhost.named.3711.1517604646.core.tgz
-rw-r--r-- 1 root root  441293 Feb 23 17:08 localhost.named.3789.1519405684.core.tgz
/var/tmp/*core* :
drwxr-xr-x 2 root root  4096 Jun 21 16:06 corefiles

Solution

The procedure is this article applies to NFX250 running nfx-2 software. For NFX250-Next Gen, NFX150, and NFX350, refer to  KB34846 - [NFX] How to locate crash files on nfx-3 software [juniper.net] .

For NFX250 running nfx-2 software, the core dump files are located in hypervisor. To find these files, perform the following steps:

  1. SSH to hypervisor.

  2. cd to /var/tmp/corefiles to find the necessary files there.

Example 

{master:0}
root@jdm> ssh hypervisor

total 6280
