    typically caused by transient issues they are especially hard to detect and troubleshoot For example assume you have a router card in your environment going up and down intermittently This transient issue generates a lot of events or noise First it generates an event with a severity state of Warning but then a short time later sometimes even within seconds it generates another event with a severity state of Info As the router card generates events that flap between severity states although you may see the warning generated by the router card initially when you start to drill down your event management console to take a closer look you see the next event generated by the router is back to Info Since it looks like everything is now fine you move on However within a few seconds the card once again generates an event with a severity state of Warning quickly followed once again by an event with a severity state of Info This event flapping continues on and on generating a lot of noise in the event console Also because the event flaps between Warning and Info so frequently it is hard to determine whether or not you do have a configuration network or service problem you need to address Detecting and Eventing on Event Flapping Both Zenoss Core the open source Zenoss product as well as the enterprise version of Zenoss Zenoss Service Dynamics Resource Manager can help you decipher the noise around event flapping and help you identify and better manage event flapping in your environment With Zenoss you get a clear actionable signal out of event flapping noise by specifying event flapping settings as part of your event configuration properties By specifying event flapping configuration properties for events if the severity level of an event changes

    or hours dramatically slash maintenance window times Significantly easier and faster installation and deployment of Zenoss means less time and money spent deploying and managing the management system Everything is monitored and managed centrally The new Zenoss Control Plane enables comprehensive monitoring and management of all the applications and services that make up the Zenoss All applications are actively monitored by default including message queues memory caches and more You can always quickly and easily see the current performance and availability posture of your monitoring system Zenoss can dynamically perform resource scheduling and allocate more memory and CPU resources as needed based on available capacity Everything is encapsulated and isolated in a container The container based approach used by Zenoss removes the hassles that have long been associated with deploying enterprise IT applications You no longer have to spend time and effort tracking down and installing dependencies dealing with version and port conflicts manually installing and configuring hosts and installing and Hadoop and OpenTSDB With the Zenoss Control Plane dependencies and configuration can be managed at the container level which provides better portability reliability and configuration management for Zenoss installations Encapsulating dependencies in containers means less time to install configure and deploy Zenoss Everything is encrypted Since monitoring systems talk to all the devices in your IT infrastructure secure communications between the components that make up the monitoring system as well as secure communications between the monitoring system and the devices or resources it manages is critical With Zenoss daemon to daemon communication is encrypted by default which means all communications between Zenoss containers as well as Zenoss communications with managed resources are secure Everything can be rolled back With Zenoss disaster recovery is baked in at the container level If you you have an unexpected problem with a Zenoss component you can quickly roll back to an earlier working snapshot in seconds Zenoss containers along with the built in snapshot and rollback capabilities provide by Zenoss mean you can recover from a disaster in minutes not hours or days Everything can be run in parallel Zenoss supports parallelization which means Zenoss can use resources across multiple physical and virtual resources The ability to split resources across multiple machines reduces total cost of ownership Zenoss also supports multi tenant single host deployments Everything can be run anywhere Because Zenoss is delivered as a container Zenoss can run on top of virtually any modern Linux distribution system that supports Docker This means that it is easy to deploy Zenoss right into your existing IT infrastructure regardless of the Linux distribution currently in use New Big Data Back End In Zenoss Core 5 RRDtool which has been at the heart of Zenoss since its inception has been replaced by an industry leading Big Data technology stack Time series read write performance and availability is significantly improved and all performance data now resides in a centralized Apache HBase Big Data back end The centralized Apache HBase cluster can be hosted on a single

    example assume you have a machine with 32 physical CPU cores running 20 VMs and each one has been allocated two virtual CPUs This means 40 virtual CPUs are competing for 32 physical CPUs creating a prime environment for stolen CPU Unfortunately just looking at the st metric can t really tell you if oversubscription is really your culprit How you go about finding the cause is going to depend on what platform you re running With XenServer or VMware you have to track down the VM find out which host that VM is assigned to and then look at the CPU utilization of the host You ll have to do even a bit more investigation if the VM is part of a cluster using DRS that should be automatically moving VMs that need more resources If you re looking at a high steal time in an operating system running in AWS you ll need to correlate the OS steal time with the information available in AWS CloudWatch For example the performance degradation you see could be a result of a CPU quota enforcement or it could be because other tenants on the same hardware are requesting more CPU resources than they should Getting Your Stolen CPU Back If you are like a lot of the folks we talk to when you first start looking at how you want to resolve any of the steal time issues you find your first instinctive thought is to assign more CPU resources to the VM and see what happens If it doesn t work it s likely due to the server being oversubscribed and so you try moving the VM to a different host For VMware environments however this isn t necessarily the best approach If you assign two CPU cores to an
