F5er Harry Kleinbourg came up with a great solution for monitoring the availability of BIG-IP APM targets not just based on the availability of the virtual service but also on its ability to handle service based on the licensed session limits. Goals The goal of this solution is for BIG-IP GTM to redirect SSL VPN users to an available BIG-IP APM. The BIG-IP APM must be considered down if the number of users reaches the license limit. However, there is not an existing built-in monitor that allow...

The Problem Application performance testing is a tricky beast.  In the good old days, you would write some code, plop it on a web server and expose it’s IP address to the world and you were ready to roll.  Testing application performance was relatively simple.  You would have your app team do timing on the various components of the application and monitor system resources and response times to see how the application would handle to the normal user and also under load. The user...

Articles in this series: Monitoring Your Network with PRTG - Overview, Installation, and Configuration In my first article in this series, I talked about the PRTG Network Monitor from Paessler and how we decided to use it for our DevCentral migration from our IT datacenter into a cloud provider.  In this article, I’m going to talk about the core of PRTG’s monitoring: it’s sensors. What is a Sensor? As the PRTG folks state: A sensor is the “heart” of the...
I was recently asked to develop health monitors on my 10.2.4HF3 LTMs for our Exchange 2010 environment. Two of the three monitors were a bit challenging, so I wanted to share what I developed.  The monitors have been sanitized to protect our environment - modify them to fit yours. *** Active Sync *** This monitor was challenging me, until I stumbled across this statement for versions 10.2.x and 11.x in SOL2167: "When Basic Authentication is enabled by configuring a User Name and Pas...
A few months back, our team moved DevCentral.f5.com from our corporate datacenter to a cloud service provider.  As part of this project, we were required to take over the tasks previously performed by our IT department.  One of the tasks that fell into my hands was to look at the monitoring and alerting for the heath of the systems in our environment.   These systems included our application tier (application, database, and storage) as well as the F5 network infrastructure (G...

Monitors are a part of just about any infrastructure that needs to be highly available. BIG-IP has a whole host of different monitoring options for keeping tabs on servers. It's important for your BIG-IP to understand the current state of the servers behind it, the services on those servers, what to do in the event of a failure, etc. The most common monitor types are simple ICMP, TCP or HTTP requests to the individual servers behind the BIG-IP device that will give some semblance of confiden...

Introduction This article details the process of using F5 Data Manager to generate storage usage reports for all users in an Active Directory (AD) Group. A report is created for each user in the group from a single CIFS file system inventory. The capability of generating such reports is available only with the Advanced Reporting Module. Problem Generating a report for each user in an AD environment can be a challenging task if each user for whom the report is to be generated has to be manua...
