As LogicMonitor’s Financial Controller, I’m proud to share some exciting news from the LogicMonitor finance department. I know, I know … “exciting” and “finance” rarely go together … but if you’re adventurous enough to read on, you’ll hear about how we’re bringing accuracy and efficiency to our accounting operations using two leading technologies: Zuora and LogicMonitor.
As hopefully you already know, LogicMonitor is the automated IT performance monitoring platform. We’re fortunate to have a rapidly expanding customer base and an ever-growing number of devices being monitored by our customers around the globe. Even better, the LogicMonitor solution allows customers to easily add devices to monitoring and scale up or down depending on their needs. But with that comes complexity in the accounting world.

A guest post by one our intrepid Support Engineers in the UK, Antony Hawkins.
“Catching the little problems you never knew you had (before they cause big problems you never want to deal with).”
So, you’ve configured and tested an NTP hierarchy through your estate and now all your devices run to the same time. You can leave it alone now, safe in the knowledge it’s working.
Can’t you? Read more »

If you are like us, you are running some type of linux configuration management tool. The value of centralized configuration and deployment is well known and hard to overstate. Puppet is our tool of choice. It is powerful and works well for us, except when things don’t go as planned. Failures of puppet can be innocuous and cosmetic, or they can cause production issues, for example when crucial updates do not get properly propagated.
In the most innocuous cases, the puppet agent craps out (we run puppet agent via cron). As nice as puppet is, we still need to goose it from time to time to get past some sort of network or host resource issue. A more dangerous case is when an administrator temporarily disables puppet runs on a host in order to perform some test or administrative task and then forgets to reenable it. In either case it’s easy to see how a host may stop receiving new puppet updates. The danger here is that this may not be noticed until that crucial update doesn’t get pushed, production is impacted, and it’s the client who notices.
Monitoring is clearly necessary in order to keep on top of this. Rather than just monitoring the status of the puppet server (a necessary, but not sufficient, state), we would like to monitor the success or failure of actual puppet runs on the end nodes themselves. For that purpose, puppet has a built in feature to export status info Read more »
Sample SAT question: xUnit is to Continuous Integration as what is to automated server deployments?
We’ve been going through lots of growth here at LogicMonitor. Part of growth means firing up new servers to deal with more customers, but we also have been adding a variety of new services: proxies that allow our customers to route around Internet issues that BGP doesn’t catch; servers that test performance and reachability of customers sites from various locations, and so on. All of which means spinning up new servers: sometimes lots of times, in QA, staging and development environments.
As old hands in running datacenter operations, we have long adhered to the tenet of not trusting people – including ourselves. People make mistakes, and can’t remember things they did to make things work. So all our servers and applications are deployed by automated tools. We happen to use Puppet, but collectively we’ve worked with cfengine, chef, and even Rightscripts.
So, for us to bring up a new server – no problem. It’s scripted, repeatable, takes no time. But how about splitting the functions of what was one server into several? And how do we know that the servers being deployed are set up correctly, if there are changes and updates? Read more »
