Zimbra Monitoring with Zabbix

Zimbra already gathers pretty much any stat you could want, and it even comes with a zmstat-chart util to create graphs from them.

But what if you want to alert on a threshold value or look at trends longer than 24 hours, or combine arbitrary metrics?

This article will show you how to import the zmstats CSV data into Zabbix.


Openshift and Flask with Virtualenv on OS X

Create a flask app for Openshift with a matching local python virtualenv to perform local testing.

In this case we'll use Python 2.7 on Mac OS X 10.9.

This post is not yet complete!

Upgrade Zabbix from 2.0.x to 2.2.x on RHEL.

My install is based on PostgreSQL 9.2.4 and partitioned to avoid the performance hit of the housekeeper process.

Wrapper script to convert CVS project to Git

I have an old CVSROOT of several projects on an archive host, and I want to create a git version of the relevant projects without bothering to copy more than I need to. Here is a script to do that. It uses rsync to copy just the relevant project and then converts it with cvs2git AKA cvs2svn.


Tmux Startup and Attach Wrapper Script

A nice feature of tmux is the support it has for scripting. It's possible to open a manipulate windows in a session you not attached to. The same script can be used from within a tmux session as well. See my blog post for an example of such a script.

The script below is what I use to start working everyday. I just sit down and type 'tmuxgo', and whether I simply detached the night before or had a power outage I will have just the window layout I want.


My tmux.conf

Have you switched from screen to tmux yet? Why not? You don't use either? How the hell do you do your job?

Here's my .tmux.conf. Big woop.


bind | split-window -h


Use tmux to simultaneously control multiple servers

Sometimes you need to make a change on several identical machines all at once. Sure you could use a tool like func or dsh or whatever, but sometimes it may be easier to use an interactive session. Maybe you are talking to numerous switches or routers and just want to issue some status queries simultaneously.

This script uses tmux to login to as many servers as you want and tile them all in the same window.



Upgrade TiVo Premiere XL to 2TB and 317 hours of HD

Upgrading a TiVo Premiere or Premiere XL to 2TB and 317 hours of space is quite easy thanks to the jmfs tool by Comer of the TiVo Community. So I upgraded last week. It took 7 hours just to copy the data, but it was worth it. My TiVo went from always on the edge of full to 48%!

Here is how to do it without a CDROM drive or Windows machine.


Mojito by the Pitcher Recipe ala Bewley

On a hot summer day there not much better than an ice cold mojito, except maybe a whole pitcher. Here's my recipe for a tasty party.



There is a new chinese restaurant (at least new to me) here in DC that has TVP. They have TVP beef and chicken, and these dishes get 4 stars from me. They also have many tasty tofu dishes (hunan tofu being my favorite) and if you order spring rolls, they usually give you a couple free (well they have given me a couple free every time I order. Not sure if it is the norm, but that has been my experience). Sushi is also available and they have my favorite, inari.

There is a $10 minimum delivery fee for free delivery, but it's well worth it.
