How Cedexis Deploys Puppet Enterprise and LogicMonitor Jointly to Support its Global Operations
Founded in 2009, Cedexis is building a faster Web. Cedexis offers visibility and control of Web performance through its community-based monitoring & analysis solution, Cedexis Radar, and its global traffic management platform, Cedexis Openmix.
Ops in the Cloud
Deploying their technology strictly in a cloud environment, Cedexis’ TechOps team follows a simple rule: “Never touch hardware.” Cedexis manages its dynamic host deployments globally across a range of managed hosting and cloud providers. To ensure uniformity across datacenters, Cedexis configures new machines identically via configuration automation tools in order to prepare each with a “blueprint” to take the Cedexis code.

“Excuse me. Did you just say that I could learn something of actual value from a marketing person?”
Yes, I did.
In case you haven’t noticed, marketing has undergone a phenomenal transformation in the last decade. Marketing has implemented complex automation platforms, like Marketo and Eloqua, that can sift through a sea of prospect data and use predictive analytics to pick out those most likely to purchase. Web analytics, too, have gone mainstream, largely due to Google giving away the functionality for free. Consequently, marketing can better quantify the ROI of what they spend. And, according to Gartner Research, 81% of companies with revenue of more than $500M have a Chief Marketing Technology Officer, and that number is expected to grow another 8% next year. By 2017, Gartner predicts that Chief Marketing Officers will be spending more on technology than CIOs!
So what does that have to do with IT monitoring?

Too busy to keep up with what’s happening on the Web? Never fear. Starting this month, LogicMonitor will begin posting our favorite tech articles, blog posts, ebooks, videos, podcasts, cat pictures and more every month. Our favorites from August:
For those of you using our MongoDB monitoring, there’s an update for replication monitoring.
There’s a few improvements over the prior datasource: it deals with authentication better; removes some assumptions about whether members of a replica set are running on common ports, etc. Most of the data points being monitored are standard, and don’t need much comment. (We find all the members; monitor their health, state, uptime, etc). Read more »
As we’ve often preached – too many alerts are just as bad as missing alerts. You don’t want your team to become inured to alerts, so they don’t take action on those indicating outages.
For those of you using Campfire as your team collaboration tool, you now have another way to help manage your infrastructure and server monitoring alerts, and ensure every alert is reacted to appropriately. LogicMonitor now integrates with Campfire using the Campfire API.
How does this integration help you react to alerts appropriately, and ensure your teams don’t suffer from alert overload? Read more »
[Originally appeared April 30, 2014 in the Packet Pushers online community, written by Steve Francis, Founder and Chief Product Officer with LogicMonitor. This is a continuation of the 'SNMP traps' blog post previously posted on the LogicMonitor blog.]
LogicMonitor is a SaaS-based IT infrastructure monitoring company, monitoring the performance, capacity and availability of thousands of different kinds of devices and applications for thousands of customers. Where possible, we don’t rely on SNMP traps – and neither should you.
Firstly, consider what a trap is – a single UDP datagram, sent from a device to notify you that something is going wrong with that device. Now, UDP (User Datagram Protocol) packets are, unlike TCP, not acknowledged, and not retransmitted if they get lost on the network and don’t arrive, since the sender has no way of knowing if it arrived or not. So, a trap is a single, unreliable notification, sent from a device at the exact time that a UDP packet is least likely to make it to the management station – as, by definition, something is going wrong. The thing going wrong may be causing spanning tree to re-compute, or routing protocols to reconverge, or interface buffers to reset due to a switchover to redundant power supply. Not the time to rely on a single packet to tell you about critical events. Traps are just not a reliable means to tell you of things that can critically affect your infrastructure – this is the main reason to avoid them if possible.
I was going to write about the differences between monitoring virtual memory on Linux and Solaris, but figured it would be beneficial to start with some fundamentals about what virtual memory is, and the differences between Solaris and Linux.
Virtual memory is used by all current operating systems. It simply means that the memory address a program requests is virtualized – not necessarily related to a physical memory address. The program may request the content of memory address 1000; the computer looks at where the current map for address 1000 is pointing, and returns the contents of that address. (Virtual address 1000 may be mapped to physical address 20.) Of course, if the memory is virtualized, that means that there is no need to actually have physical memory on the server for every address the programs think they can address – so the programs can believe the server to have more memory than it physically does. Virtual memory addresses do not need to be mapped to anything until they are allocated by a program. And a virtual memory address can be mapped not to a physical block of memory for storage, but to a block on a hard drive. Read more »

IT managers either adopt a DevOps philosophy or think it’s passé. Either way, it’s hard to argue with the foundational principle that IT automation isn’t just a trend but rather a key tenant of today’s IT Ops environment. When done right, automation brings efficiency to IT teams.
At LogicMonitor – OneLogin’s newest integration partner that offers infrastructure performance monitoring via it’s SaaS-based platform — it’s often said that “the best way to get a promotion is to automate your way out of a job.” You may wonder what the reasoning is for this and it’s simple: automating manual tasks is fundamental to the LogicMonitor product philosophy. A team that monitors thousands of data points each day are also testing new data centers, adding equipment vendors, and performing the laundry list of daily IT Ops responsibilities. Efficiency isn’t nice to have — it’s a requirement!
Our integration with OneLogin reduces the time required for user management configuration by over 50%, as the integration completely removes the need to manage users and security policies within LogicMonitor.

At LogicMonitor, our monitoring philosophy is to provide customers with actionable intelligence. Great examples of actionable intelligence are the alerts we send you about performance issues in your IT infrastructure. Providing meaningful performance and health metrics is our bread and butter, but we want to avoid overwhelming you with alerts as overload often results in apathy, defeating the original purpose of monitoring.
Consider the case of when a Windows Server running SQL database receives a credential change. Any new client request to that server will then fail, and with every failure a Window Event will trigger. When your server has an issue and 100 different clients are trying to access it unsuccessfully, you’ll see an event, and an alert, for each and every failure. This quickly becomes overwhelming, and you’ll probably turn off EventSource alerting to avoid the alert storm. Your frustration in this case would be understandable – a single Windows Server can be responsible for thousands of event alerts in a very short time period. But turning off event alerting has potentially dire consequences: you can miss crucial events you actually need alerting on, so you’re throwing the baby out with the bath water.
Performance monitoring for all your infrastructure & applications. In minutes, not hours.
