cr2-eqdfw (MX204) vhclient log noise
Closed, ResolvedPublic

Description

The newly provisioned cr2-eqdfw, a MX204 is logging this every minute:

Aug 31 11:53:45  cr2-eqdfw vhclient.5357.daemon: vhclient instantiated by /bin/sh
Aug 31 11:53:45  cr2-eqdfw vhclient.5357.daemon: rsh -JU __juniper_private5__ 192.168.1.2 export PATH=$PATH:/usr/sbin:/sbin/ ; echo -e Write threshold rate/duration=4/1000 > /etc/diskmon.conf

Two lines every minute is a bit excessive even by Juniper standards, and makes show log messages a bit unusable. Let's please fix that, possibly with the help of JTAC?

Opened JTAC case 2018-0904-0650.

Edit, this might be PR1315128

If so the fix is to upgrade to 17.4R2 (released a week ago...), and filter out the logs until then.

Still waiting for JTAC.
