Bash scripting: checking if a variable is a number

Sometime ago I had a simple problem with bash scripting. I liked to check if a variable is a number or not. First I'd looked up into Advanced Bash Scripting Guide but didn't found anything. So my first approach was:

[ -z "`echo $VARIABLE | tr -d "[:digit:]"`" ]

But I didn't like it because of tr usage. So after some discussion with other people I came to the following solution:

[ $VARIABLE -eq $VARIABLE ]

It works great and could be used in a bash script like this:

if [ $VARIABLE -eq $VARIABLE 2> /dev/null ]; then
echo $VARIABLE is a number
else
echo $VARIABLE isn't a number
fi

Nagios 2.4

Just downloaded version 2.4 sources. Trying to config it but something is still wrong. Last time I've done compilation and configuartion of Nagios was during version 2.0 and I hadn't so many problems as now. First it seems that the init script have to be rewritten. stop method doesn't work at all.
