[smokeping-users] DNS Probe showing latency

[Kamran Siddiqui/NYLIC]

Now that I got the DNS probe to work (with your help, of course) I am
noticing that somehow smokeping is reporting higher latency and packet
loss. It is showing anywhere from 2ms to 20ms. So I tried to run dig from
command line for hosts that are giving high latency and I consistently get
2-3ms reported. I am using bind 9.3.0 utilities on Solaris 2.8. Here is the
dig output

# ./dig www.cisco.com @10.10.10.10

; <<>> DiG 9.3.0 <<>> www.cisco.com @10.10.10.10
;; global options:  printcmd

Is this normal for smokeping to see higher response time than from command
line. The packet loss is about 5%-8%.

My config looks straight forward

+DNS
binary = /opt/bind9/bin/dig

+ Services
menu = Services
title = Check Service Availability

### Collect CNJ DNS performance
++ DNS-CNJ
menu = DNS-CNJ
title = DNS Resolution Through CNJ
probe = DNS

+++ Cisco
menu = Cisco
title = www.cisco.com DNS Lookup
host = 10.10.10.10
++++ PROBE_CONF
lookup=www.cisco.com


Is there something I can do to tweak it to at least fix the packet loss
problem? I am using tsmoke.pl and it shows DNS services to be up only
around 85% or so. I'd like to see the number in the 98% or above range.
