With the introduction of Zabbix 2.0 & above, the ability to monitor JMX counters without deploying additional software has been introduced in the form of a daemon called “Zabbix Java Gateway“. The most common use of JMX is monitoring thread counts and memory usage of any Java enabled application via the resource objects called MBeans (Managed Beans). See wiki for full explanation. Zabbix Java Gateway can be installed alongside Zabbix Server or as a standalone server.
I was recently given a task to capture the total size of deleted items in Recycle Bin for all user profiles on a server and report an alert when it reaches the defined threshold irrespective of the number of volumes on the server. The idea behind this was to ensure no one leaves large deleted files on their recycle bin that might lead to disk been full. This is the approach I have taken to achieve this and it could be better, so I welcome suggestions and improvements.
If you are running a service based mission critical applications on a Windows server and you would like to be notified immediately when the application service(s) goes down, then this post is for you and with the assumption that you are using Zabbix as your monitoring tool.

This post is simply to show us how to find a Perfmon counter key value for use when adding a Perfmon counter in Zabbix. – On your Windows server, click Start Administrative Tools Performance Monitor – Right-click on Performance Monitor Click on Properties – Under the properties screen, click on Data tab. As seen the default counter is ‘Processor Time in percentage‘ – The Key value for zabbix would be in this format: perf_counter[\Processor Information(_Total)\% Processor Time] I have also added a few more: – DNS Caching Memory: perf_counter[“\DNS\Caching Memory”]
This post is in continuation of my earlier post on ‘How to install Zabbix on CentOS‘ and here I will show us how to deploy the Zabbix agent on a Windows machine and add the server into Zabbix so we can start monitoring it.
