You might noticed MySQL statistics aren’t being show in Netdata. Here’s what I ran into.

Error: “MySQLdb or PyMySQL module is needed to use mysql.chart.py plugin”

The required python libraries for MySQL are missing, so you simply need to install them. For Ubuntu/Debian the following command should correct it.

Shell

Setting up Netdata MySQL User

You might also see these errors in your log.

Plain Text

The fix is simple, add a user called Netdata with a password. Note, you can setup the Netdata user without a password, but this may expose information to the system that you might not want. Full information is located on Netdata’s website.

So let’s get Netdata pulling MySQL data.

Fast, open and potentially insecure no password optiom

This will just work, but leave a user on your MySQL instance without a password.

Plain Text

Password based polling

Let’s run the same command as above but give the user a password.

Now we need to tell Netdata the password.

iriver’s UNIT2 detailed on teaser site

One of the sexist and functional MP3 devices I've seen yet. The iPod had its time, and even the smallest iPod is really sexy. But this is just over the top.
iriver's UNIT2 detailed on teaser site -

Filed under: , ,


Mmm, there's nothing like fragmented high-resolution photos of a lust-worthy device to get us salivating, and iriver's marketing department has done an exquisite job figuring that out. Shortly after unveiling the sexiest e-dictionary known to man, the much anticipated UNIT2 conglomerate received its own teaser site, complete with photos and a few extra details you should know. While it has yet to lose its mystique, we now know (officially, at least) that the base will act as a DVD player, TV tuner, access point, charging station, hard drive, and a speaker station. Aside from sporting an SD slot and USB connectivity, this beauty will handle music, movies, photos, eBooks, and WiFi streaming without breaking a sweat. Mechanically, you can expect an automatic sliding door, detachable display, slot-loaded CD / DVD deck, and a 78-key controller to manage the fun. No word yet on the price, but be sure to peek the additional photos below.
