Extracting Latency, Loss and Jitter from PING responses.

I have a script that pings several hosts and stores the response in a text file (see below)

Once this file is created, the intention is to populate a database with the values for 'packet loss', 'avg' and 'mdev', but first I have to extract this data.

avg=latency
mdev = jitter
packet loss = loss

My question is on how to extract the 'packet loss' 'avg' and 'mdev' values from the file, possibly in the form of .... Host# $avg $loss $jitter

Code:

Wed Dec  3 15:25:14 EST 2008
PING Host11 (10.0.201.51) 56(84) bytes of data.
--- Host11 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4010ms
rtt min/avg/max/mdev = 7.400/41.641/59.604/17.946 ms
.
Wed Dec  3 15:25:18 EST 2008
PING Host12 (10.0.202.51) 56(84) bytes of data.
--- Host12 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4016ms
rtt min/avg/max/mdev = 43.804/55.694/67.728/9.359 ms
.

PING Host13 (10.0.205.51) 56(84) bytes of data.
--- Host13 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4007ms
rtt min/avg/max/mdev = 40.237/56.283/68.973/10.433 ms
.
Wed Dec  3 15:25:26 EST 2008
PING Host14 (10.0.201.52) 56(84) bytes of data.
--- Host14 ping statistics ---
5 packets transmitted, 5 received, 0% packet loss, time 4007ms
rtt min/avg/max/mdev = 36.053/65.964/96.782/20.642 ms

Thanks in advance.

mrtg-ping-probe

MRTG-PING-PROBE(1)					      General Commands Manual						MRTG-PING-PROBE(1)

NAME

       mrtg-ping-probe - ping probe module for Multi Router Traffic Grapher

DESCRIPTION

       mrtg-ping-probe is a ping probe module for MRTG 2.x.  It is used to monitor the round trip time and packet loss to networked devices.  MRTG
       uses the output of mrtg-ping-probe to generate graphs visualizing minimum and maximum round trip times or packet loss.

       mrtg-ping-probe is not run directly, but is called by MRTG as a helper when it needs to determine ping time to a host.

       Act responsibly: do not use mrtg-ping-probe to ping devices without the owner's permission.  Just imagine if 10,000 people decided to  ping
       your hosts!  mrtg-ping-probe is meant to be used within your network to get round trip time performance figures for your network.

OPTIONS

       To  use	mrtg-ping-probe you need to configure MRTG to call it from within the definition of a target host. This is done in the MRTG config
       file, which is usually /etc/mrtg.conf.

       Here's an example snippet: change the target name and IP address to suit your needs.

       Target[your.target.ping]: `/usr/bin/mrtg-ping-probe 123.456.789.123`
       SetEnv[your.target.ping]: MRTG_INT_IP="123.456.789.123" MRTG_INT_DESCR="ping"
       MaxBytes[your.target.ping]: 100
       AbsMax[your.target.ping]: 200
       Options[your.target.ping]: gauge, growright
       YLegend[your.target.ping]: ping time (ms)
       ShortLegend[your.target.ping]: ms
       Legend1[your.target.ping]: Maximum Round Trip Time in ms
       Legend2[your.target.ping]: Minimum Round Trip Time in ms
       Legend3[your.target.ping]: Maximal 5 Minute Maximum Round Trip Time in ms
       Legend4[your.target.ping]: Maximal 5 Minute Minimum Round Trip Time in ms
       LegendI[your.target.ping]: &nbsp;Max:
       LegendO[your.target.ping]: &nbsp;Min:

       Pay close attention to the backticks in the first line which tell MRTG to execute the nominated external program. Note also that  you  need
       to use the "gauge" option, since the results of subsequent ping probes are independant values and not an incrementing counter.
