can use to store system logfiles. Here we can see that there’s almost nothing on RE1’s
hard disk (/dev/ad1s1f, mounted on /var):
aviva@router1a> show system storage | except /dev/vn
Filesystem Size Used Avail Capacity Mounted on
/dev/ad0s1a 77M 37M 35M 51% /
devfs 16K 16K 0B 100% /dev/
mfs:172 1.5G 4.0K 1.3G 0% /tmp
/dev/ad0s1e 12M 9.0K 11M 0% /config
procfs 4.0K 4.0K 0B 100% /proc
/dev/ad1s1f 17G 622M 15G 4% /var
The messages you save to RE1 are placed in the file /var/log/messages and include the
string re0 after the timestamp and router name to distinguish those messages that
originated from RE0 from the messages from RE1:

To have RE1 send its log messages to files on RE0, you configure this in the configuration
file on RE1:
aviva@router1> request routing-engine login re1
aviva@router1a> configure
[edit]
aviva@router1a# set system syslog host other-routing-engine authorization notice
aviva@router1a# commit and-quit
Because this is the same configuration as on RE0, you can also configure both
Routing Engines from RE0:
[edit system syslog]
aviva@router1# set host other-routing-engine authorization notice
aviva@router1# commit synchronize
Then check for the messages on RE0:
aviva@router1a> exit
aviva@router1> show log messages | last
