Monitor Atlantis ILIO via SNMP

Written by Ingmar Verheij on June 14th, 2013. Posted in Atlantis ILIO, Scripting / Programming

Atlantis ILIO Center can monitor the health and availability of ILIO Session- and Replication hosts. If necessary ILIO Center sends alerts via SMTP (aka Mail) or via a SNMP trap (push). However, if the ILIO Center experiences an unexpected shutdown or network connectivity is lost, a SNMP trap is never sent (or in case of lost of network connectivity: the monitoring system does not receive the trap).

Additional monitoring can be done via ping or by monitoring the state of the VM. However, verifying the availability of a machine via ping could result in false-positives and not each monitoring system can monitor the state of a VM, therefore you might want to monitor via SNMP polling (pull).

A vanilla installation of Atlantis ILIO (Center) does not have an SNMP agent installed, therefore I wrote a script that can push the agent and/or update the configuration. You can find the download at the bottom of this article.

Demystifying the Atlantis ILIO replication host – part 2

Written by Ingmar Verheij on April 29th, 2013. Posted in Atlantis ILIO, Demystified

In the first part of this article I’ve explained what Atlantis ILIO products and components there are, explained what type of Session Hosts there are and how the Replication Host works. In this part I will dive a bit deeper in the boot process and the how the hosts are managed.

Demystifying the Atlantis ILIO replication host – part 1

When Atlantis Computing added persistent support for their ILIO Diskless VDI in Q1 2013 I couldn’t wait to get my hands on a copy. Last week I was able to deploy an Atlantis ILIO environment with a Replication Host.

In the first part of this article I will explain what the replication host is, how it’s used and how it works. In the second part I’ll dive into the boot process and how the hosts are managed.

Hacking into the Atlantis ILIO database

Written by Ingmar Verheij on April 27th, 2013. Posted in Atlantis ILIO

The content of a products database can tell you a lot about the inner working of that product. The Atlantis ILIO database stores the configuration and resource usage of the different components.

Watch out, we got a badass over hereSince I’m building an environment including Atlantis ILIO I thought it would be good to learn about the internals of it. Having to troubleshoot some configuration issues motivated me to see (and maybe change) the configuration. So I’m not a badass hacking the database for malicious reasons.
