Love thy unix, but also love thy ports…

> All good? Great. But, another email comes in: “Could you please
> send me a list of all the IDs that caused an error #11245″. Sure, no problem:

Alternatively, awk could be avoided with the tiny modification to the regex:

… | grep REQUEST_ID | sed -r ’s/^.*REQUEST_ID:([0-9]+).*$/\1/g’

or even:

… | perl -ne ‘print $1 if /REQUEST_ID:(\d+)/’

;-)

I never thought that a day would come where I could say: I understand stuff like written above. Lo and behold, the day has come.

Love the sed,awk,grep and Unix in a Nutshell - the book that made them accessible to me :)

No problem at all. I also don’t come from a networking/server background. So my comments aren’t the most informed on these topic. I know we are trying to reinvent the wheel here but all the other tools are just so complicated to install and use etc.

Man, I appreciate the link and all the feedback! I came into python from scientific programming side so I never took much interest in network related stuff. Having such an easy access to SSH functionality seems great! And it’s a nice client-side complement to the idea that I’ve had.

In general, your comments are spot on - I never knew about any of this fancy web-related functionality (I’m referring to both of your posts). Truth be told, I only learned about the meta refresh tag from guys that own this blog (the old versions of code had a javascript refresh instead X) ).

Thanks

I agree with your assessment. What I hacked together only works for local networks. But I just wanted to illustrate how the code can be extended.

I can see this script being easily combined with a python ssh like the one mentioned here:

http://commandline.org.uk/python/sftp-python-really-simple-ssh/

You can easily add the ability to ssh into another machine and then get its stats. Could be useful if you want to monitor a bunch of machines.

Thanks for your comment ducky! I can see how this is useful in general. However, I don’t see how this solution handles the situation where you’re monitoring a server which is “invisible” outside of the local network. In that case, the code should still resort to compiling a HTML file and scping it to a remote public server. Or am I mistaken?

Thanks for the pastebin link to, I haven’t heard about it before.

Great idea.
You can even turn this into a self-refreshing web page using cherrypy.

http://pastebin.com/f5dac95d4

the code has two further dependencies:
1) cherrypy package
2) a file called cmds.txt which has all the commands to run.

Run the code and browse to http://localhost:8080/

HAPPY BIRTHDAY CALYX PEOPLE!

Wish you all the best and many many geeky years to come!

Now that you have my congrats and admiration, on to the beer contest :P

foo & bar - two well known variable names to all of us who actually learned to program from books, rather than from other “real humans” :)

unfortunatelly (for me), I don’t know the other one, but I guess Mr Foo and Mrs Bar guarantee me at least a small beer!
