Host sFlow progress

The open source Host sFlow project has made significant progress over the last two years. The rapidly increasing number of downloads reflects the projects maturity and the unique functionality delivered by the sFlow standard in unifying network, server and application performance monitoring of large scale cloud environments.

Starting with Linux, the Host sFlow project has added support for FreeBSD, Solaris and Windows. Installed on hypervisors, Host sFlow reports on the performance of the hypervisor and all the virtual machines. Currently supported hypervisors include: Microsoft Hyper-V, Citrix XenServer, Xen Cloud Platform (XCP)KVM and libvirt. In addition, the Host sFlow agent is extensible and a growing number of projects implement sFlow instrumentation in virtual switches (Open vSwitch, Hyper-V extensible virtual switch), popular web servers (Apache, NGINX), Memcached, application servers (Java, Tomcat) and even in-house applications written in scripting languages (PHP, Python, Ruby, Perl).

Popular open source projects such as Ganglia and Graphite offer scalable collection and reporting of sFlow metrics from large scale compute, virtual machine pools, web farms, Java application servers and Memcache clusters.

Deploying Host sFlow agents on servers extends the sFlow monitoring built into networking devices from leading vendors, including: IBM, HP, Dell, Cisco, Juniper, Brocade, F5, Alcatel-Lucent, Arista Networks, Allied Telesis, Extreme Networks, Fortinet, Hitachi, Huawei, NEC, ZTE and others. The combination of sFlow in servers and switches delivers integrated, end-to-end visibility into cloud computing, software defined networking and converged storage.
