Have to admit the blog was pretty outdated, with no new posts, lack of an SSL certificate. Being pretty busy lately, but now that I have some free time finally decided to migrate my blog from Ghost, it was running a pretty old version, and no way to upgrade to a new Ghost version without some hacking, so, I heard about Hugo before and since is Go and I’m using Go a lot lately, decided to…

I’m using InfluxDB a lot lately, InfluxDB is a time-series database written in Go. InfluxDB is easy to setup and to use, it comes with a CLI like MySQL for example and the commands are very similar, also, you have a web UI to make things even easier. If you want to develop applications using InfluxDB there is a ton of client libraries(Go, Python, Java, Ruby, etc.) too. In this tutorial we…
It’s almost new year and the urge to upgrade my blog comes back. Well, has been a while since I’m using Octopress and so far was working great, but the lack of updates(I know Octopress 3.0 is coming) and plugins make me wanted something new, I started searching for a replacement, I tried Pelican, Hexo and Ghost. The standard choice would be Pelican, since it’s Python. But Ghost…
I’m old fashion and in some cases I like to compile my stuff, Zabbix is one of these cases. You can add/remove features directly with ./configure, and mess around with some timeouts of zabbix_server and zabbix_agentd for example. In this tutorial, we will not change anything on the source code. We are going install Zabbix version 2.4.6 with MySQL, Nginx and PHP-FPM. This is the stack of what…
In a previous post we installed the tools necessary to access Microsoft SQL Server, continuing our quest I needed to monitor some filegroups and decided to create something like Pyora. It only monitors filegroups (Primary used and Log used), but I plan to add more items like datasize, logcachehit, etc. The idea is pretty simple, ./pyssql.py fetch data from SQL Server via Zabbix. Follow the…
Mustache is a template system logic-less(no ifs, else’s or for loops) and can be used for HTML, config files, source code and so on. CFEngine 3.6.x have support for Mustache, in this tutorial we will create a template and a CFEngine rule to parse the template and generate the file that we want. Create the template file /tmp/template.mustache My hostname is: {{hostname}} My name is: {{name}}…

CentOS 6.5 ships with kernel 2.6 and it’s a quite old for now(CentOS 7 already comes with 3.10), but compile a kernel on CentOS is a mess and it’s not recommended. But fear no more, guys from Elrepo took care of that for us and made a package, let’s see how we can install it. Enable ELRepo Project repository rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org rpm -Uvh…
I’m learning Django 1.7 lately and nothing better than practice and create something from scratch. I have a bunch of scripts to tests webservices(XML, soap, etc.) in python using requests library, it works well so far. It returns the time it spent running, the result in an XML format and based on these data I make decisions(send email, feed it to a monitoring tool, etc.). When it’s 1…
I created a template to monitor CFEngine with Zabbix, that monitor processes, memory use and the promise summary log. Below what is included on the template: Process CF-serverd Process CF-monitord Process CF-execd Memory use process CF-serverd Memory use process CF-monitord Memory use process CF-execd Log cf-engine - Log view of /var/cfengine/promise_summary.log CFEngine listen port 5308 and…

I’m lazy when come to do repetitive tasks and it’s nice when machines do the work for us, specially boring ones like us sysadmins have to do daily. Example: Check if that file exists for me at N servers. Install a package on hundreds of servers. Delete a user on all servers and so on... Haven't you heard of fabric yet? Fabric is a Python library that provides automation using…

The past In the last year I was using Mezzanine as CMS that is built using the Django Framework, it’s clean and based on Twitter Bootstrap theme. For my needs it works, but for a reason that I don’t remember I never got syntax highlighting working on it. A whole new easy world It all began when I started using Gitlab as repository and use Markdown on a daily basis to write stuff on it.

In the past I used Zabora to monitor Oracle, but for large environments was a pain to admin and let’s not talk about monitor tons of tablespaces. I tried to use other things like Orabbix but since is Java I preferred stay away. Today Zabbix have some nice improvements like macros and Discovery, so we can set the database settings(user,password,database and such) on the host using macros and…
Multi-Mechanize is an open source framework for performance and load testing. It runs concurrent Python scripts to generate load (synthetic transactions) against a remote site or service. Test output reports are saved as HTML or JMeter-compatible XML. I will use pip to install the package but you can download the source and install it manually: (bicofino.io)danilochilene@undead:~$ pip install…
