Hello Vernon I've written a script that gathers data from the squidclient util (just called client in the earlier versions). I've just started collecting data so I don't have error status's set up yet ...

The squidclient util will give can give you ridiculous amounts of data on squid memory usage, disk IO, 5min and 60min averages etc. Squidclient mgr:menu will tell you what you can get.

You should be able to change the client script to grab what ever data you want ... On the hobbit server

On the hobbit client

Create Squid.sh in the ext directory #!/bin/sh #Script to COLUMN=squid # Name of the column COLUMN1=squidclients COLOR=green # By default, everything is OK MSG="Squid Status"

Get Squid traffic in and out.

VAR2=/usr/local/squid/bin/squidclient mgr:5min | awk '/server.http.kbytes_/||/client_http.kbytes_/{print $0}' | sed -e 's/=/:/g' -e 's/\/sec//g' -e 's/server\.http\.kbytes_/serverhttpbits/g' -e 's/client\_http\.kbytes_/clienthttpbits/g' |awk '{print $1,$2,$3*8*1024}'

Get number of connected clients.

VAR3=/usr/local/squid/bin/squidclient mgr:info | awk '/Number of clients accessing cache/{print $0}'| sed -e 's/Number of clients accessing cache\:/numberofclients\ \:/' -e 's/\//g' -e 's/\ //g'

Tell Hobbit about it

$BB $BBDISP "status $MACHINE.$COLUMN $COLOR date <br><b>Data in and out of cache 5 minute average</b> $VAR2 " $BB $BBDISP "status $MACHINE.$COLUMN1 $COLOR date $VAR3 " exit 0

Add entry to run the script in clientlaunch.cfg

[squid] DISABLED ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg CMD $HOBBITCLIENTHOME/ext/squid.sh LOGFILE $HOBBITCLIENTHOME/logs/squid.log INTERVAL 5m

That gives me pretty graphs about traffic and number of clients.

Hope that helps.

Hi all

I detest reinventing wheels, so let's first check if they exist.

Has anybody got anything to monitor Squid and/or Dansguardian?
