Zabbix Linux vfs User parameter Templates

Zabbix monitoring offers several virtual file system item types out of the box. But there are still some missing. I created a GitHup Repository to provide some additional items as User parameter.

During my daily work I was tasked with two additional values, Zabbix should provide to our Administrators:

  • Were Linux configuration files from a certain installed daemon modified? (/etc/postfix/)
  • What is the timestamp of the oldest file in a certain directory? (EDI)

In both cases, the affected machines are Debian Linux virtual machines with Zabbix agent 3.4+ installed and configured. Zabbix offers no way to solve these challenges out of the box, but is easily customizable via User Parameter and custom Low Level Discovery to add this features.

Installing the Microsoft ODBC Driver for SQL Server on Debian Linux with Saltstack

Installing the Microsoft ODBC Driver for SQL Server on Debian Linux (msodbcsql17) with Saltstack requires to pass ACCEPT_EULA=Y to the package manager. This blog post shows a possible solution.

Introduction

Microsoft offers several open source utilities for quite some time now. One is the Microsoft ODBC Driver for SQL Server on Linux which can be leveraged with unixodbc. In my case, I need this driver to query Microsoft SQL Server for my Zabbix ODBC monitoring, to execute native SQL queries for monitoring purposes. As I have to take control over 30+ Zabbix Proxies, I’m currently transforming all of them into Salt minions. My goal here is to achieve 100% automation, as soon as I install the Salt minion on a fresh Debian Linux.

Zabbix: Simple file count for Linux

Watch the files count of a dir on Linux with Zabbix.

In EDI based communications you often have a dir where EDI files get saved and wait for processing. Every now and then these processes don’t work and the file count grows. Of course this is only one example, but it’s often handy to have a trigger fire, when a certain folder has more than X files in it.

HowTo: Update Seafile Server for generic Linux to version 6.2.5 64bit

Seafile Server is an open source alternative to public cloud storage providers like Dropbox, Microsoft OneDrive, Apple iCloud, Google Drive and Citrix Sharefile.
