+0 Vote Up -1Vote Down

Devopsdays Mountainview sold out in a short 3 hours .. but there's other events that will breath devops this summer.
DrupalCon in Munich will be one of them ..

Some of you might have noticed that I`m cochairing the devops track for DrupalCon Munich,
The CFP is open till the 11th of this month and we are still actively looking for speakers.

We're trying to bridge the gap between drupal developers and the people that put their code to production, at scale.
But also enhancing the knowledge of infrastructure components Drupal developers depend on.

We're looking for talks both on culture (both success stories and failure) , automation, …

how to determine the runtime and start time of a Linux process
+0 Vote Up -1Vote Down

Yesterday, I needed to determine the runtime of a Linux process for a monitoring script.

Cos the format for start_time of the ps command may change if the process was not started in the same year, I decided to take the neccessary informations from the /proc/<PID>/stat file.

In this file the process start time since boot is defined at the twenty-second field, expressed in Jiffies – the scale unit of the system timer. (One Jiffie is one tick of the system timer).

To convert Jiffies to seconds I just have to …

Percona Monitoring Plugins fix: Query Response Time
+0 Vote Up -0Vote Down

After switching from the Better Cacti Templates to the Percona Monitoring Plugins we suffered from the Query Response Time and the Query Time Histogram not graphing at all.

It took me a while to figure out why our new instance wasn’t graphing: the response time query was performing and the script was picking up its values. Also the rrd files were created but for some bizarre reason all values were set to “NaN”, in rrd/cacti terms: Not a …

MySQL monitoring: storing, not caching
+2 Vote Up -0Vote Down

I've followed with interest on Baron's Why don’t our new Nagios plugins use caching? and Sheeri's Caching for Monitoring: Timing is Everything. I wish to present my take on this, from mycheckpoint's point of view.

So mycheckpoint works in a completely different way. On one hand, it doesn't bother with caching. On the other hand, it doesn't bother …

MySQL replication monitoring on Ubuntu 10.04 with Nagios and NRPE
+0 Vote Up -0Vote Down

If you're using MySQL replication, then you're probably counting on it for some fairly important need. Monitoring via something like Nagios is generally considered a best practice. This article assumes you've already got your Nagios server setup and your intention is to add a Ubuntu 10.04 NRPE client. This article also assumes the Ubuntu 10.04 NRPE client is your MySQL replication master, not the slave. The OS of the slave does not matter.

Getting the Nagios NRPE client setup on Ubuntu 10.04

At first it wasn't clear what packages would be appropriate packages to install. I was initially misled by the naming of the nrpe package, but I …

Monitoring your monitoring tools (MONyog inside) !
+6 Vote Up -1Vote Down

Regardless of the monitoring tool you use to monitor your databases, it can be better to monitor this tool.
No, it’s not a joke ! Do you think you can have a benefit with a monitoring tool not connected to your servers ? ( without being alerted )

I choose to talk about MONyog here but this can apply to all existing monitoring tools.
I just want to share the message, the tool does not matter, so, do it !

So, let me explain how to control if you have fresh data with MONyog.
With MONyog it’s easy because it’s an agentless monitoring tool.

There are two ways to check that :

Per …

Announcing common_schema: common views & routines for MySQL
+1 Vote Up -0Vote Down

Today I have released common_schema, a utility schema for MySQL which includes many views and functions, and is aimed to be installed on any MySQL server.

What does it do?

There are views answering for all sorts of useful information: stuff related to schema analysis, data dimensions, monitoring, processes & transactions, security, internals... There are basic functions answering for common needs.

Some of the views/routines simply formalize those queries we tend to write over and over again. Others take the place of external tools, …
