InfluxDB 2.0
docker run --name influxdb -p 9999:9999 quay.io/influxdb/influxdb:2.0.0-alphaPrometheus exporter describes an application that runs on the sFlow-RT analytics platform that converts real-time streaming telemetry from industry standard sFlow agents. Host, Docker, Swarm and Kubernetes monitoring describes how to deploy agents on popular container orchestration platforms.

Islamabad Chapter Brings First Internet Governance Event to Quetta, Pakistan
The 5th Pakistan School on Internet Governance (pkSIG 2019) was successfully held last month in Quetta, Pakistan. This represents a significant achievement for the Internet Society Pakistan Islamabad Chapter as it played an instrumental role in bringing the first-ever Internet Governance event to the provincial capital of Balochistan.
For those who may not know, Balochistan has the largest land area among the four provinces of Pakistan, yet it is the least populated and least developed. Only 27% of its population lives in urban areas and Internet penetration is low. Finding adequate sponsors, and more importantly, diversity among the students to participate was a critical concern. But, pkSIG 2019 in Quetta proved to be one of the best editions of this school.
Over 60 people (one-third of them female) registered for the event, including students, professionals, startup founders, speakers, and some guests who showed keen interest in the program. Following a four-week long process of registration and shortlisting, 35 students were selected for pkSIG 2019 and five were awarded fellowships. Since all the sessions were livestreamed, a sizeable audience participated online as well. (The sessions and presentations are available online.)
“It’s our fifth consecutive year conducting pkSIG – Continue reading
VMware NSX Killed My EVPN Fabric
A while ago I had an interesting discussion with someone running VMware NSX on top of VXLAN+EVPN fabric - a pretty common scenario considering:
- NSX’s insistence on having all VXLAN uplink from the same server in the same subnet;
- Data center switching vendors being on a lemming-like run praising EVPN+VXLAN;
- Non-FANG environments being somewhat reluctant to connect a server to a single switch.
His fabric was running well… apart from the weird times when someone started tons of new VMs.

Red Hat Ansible Tower offers value by allowing automation to scale in a checked manner - users can run playbooks for only the processes and targets they need access to, and no further.
Not only does Ansible Tower provide automation at scale, but it also integrates with several external platforms. In many cases, this means that users can use the interface they are accustomed to while launching Ansible Tower templates in the background.
One of the most ubiquitous self service platforms in use today is ServiceNow, and many of the enterprise conversations had with Ansible Tower customers focus on ServiceNow integration. With this in mind, this blog entry walks through the steps to set up your ServiceNow instance to make outbound RESTful API calls into Ansible Tower, using OAuth2 authentication.
This is part 3 in a multi-part series, feel free to refer to part 1 and part 2 for more context.
The following software versions are used:
- Ansible Tower: 3.4, 3.5
- ServiceNow: London, Madrid
If you sign up for a ServiceNow Developer account, ServiceNow offers a free instance that can be used for replicating and testing this functionality. Your ServiceNow instance needs to be able Continue reading

Templating Device Configurations
One of the core functions of network automation is the ability to generate network device configurations from a template. This is a discrete, intentional process which unfortunately is often conflated with the totally separate act of applying a rendered configuration to a device. In this article we'll look at how to establish a template from existing configurations, define and organize variable data, and ultimately render a series of configurations automatically using a simple Python script.
What is a Template?
The term template describes any sort of mold or pattern from which new, identical objects can be created. For instance, a cookie cutter is a sort of template that can be used to create an arbitrary number of identically-shaped cookies from a sheet of dough. But in our case, we're inexplicably more interested in creating network device configuration files than baking cookies, and creating wholly identical copies of a file isn't terribly useful, since each network device typically has a handful of unique characteristics such as hostname, authentication credentials, IP addresses, and so on.
To address this need to define changing pieces of data within an otherwise unchanging document, we employ variables. A variable serves as a placeholder within the template, Continue reading

Announcing the 2020 U.S. Presidential Campaign Audit
Today, the Internet Society’s Online Trust Alliance released a new report, the “2020 U.S. Presidential Campaign Audit,” analyzing the 23 top current presidential campaigns and their commitment to email/domain protection, website security, and responsible privacy practices. OTA evaluated the campaigns using the same methodology we used to assess nearly 1,200 organizations in the main Online Trust Audit released in April.
An alarming 70% of the campaign websites reviewed in the audit failed to meet OTA’s privacy and security standards, potentially exposing visitors to unnecessary risks. Only seven (30%) of the analyzed campaigns made the Honor Roll, a designation recognizing campaigns that displayed a commitment to using best practices to safeguard visitor information. The 2020 campaigns, taken together as a sector, lagged behind the Honor Roll average of all other sectors (70%) in the 2018 Online Trust Audit, and were far short of the Honor Roll achievement of 91% by U.S. federal government organizations.
To qualify for the Honor Roll, campaigns must have an overall score of 80% or higher, with no failure in any of the three categories examined. The campaigns who made the Honor Roll are:
- Pete Buttigieg
- Kamala Harris
- Amy Klobuchar
- Beto O’Rourke
- Bernie Continue reading
