#DOXLON Nov 2016 - ELK Stack & Beats, Splunk @ Strft & cgroupv2 at Facebook

Posted by : David Gildeh | DOXLON, DevOps, Docker, Linux

At the November DOXLON, Facebook gave us an in-depth look into the way we have managed containers over the past 8 years, and why a complete overhaul is coming, with an entirely new control group system. Epam Systems showed us how to use the ELK stack together with Beats Plugin data shippers for system metrics, along with monitoring multiple Docker containers. Neil Chowdhury at Strft focused on how they are using Splunk and data models for collaboration, and the need for semantic logging.

Kubernetes vs. Mesos vs. Swarm — An Opinionated Discussion

Posted by : Ivana Ivanovic | Docker Containers, DOXLON, Docker

The Meetup started with lighting talks about Kubernetes and Mesos in production at two large companies, Pearson and Schibsted. This was followed by a panel discussion, moderated by our CTO Steven Acreman.

Monitoring is a Journey, Not a Destination

Posted by : David Gildeh | Monitoring Wisdom

Not a lot of people know this, but our original name, Dataloop.IO, derives from the term OODA Loop (It was either that or OODA Daddy!). OODA Loop is a term I learned about in the Big Data space when we were starting out, and has really driven our thinking around how we’ve designed Outlyer to help online services become more agile and competitive through monitoring.

Build vs. Buy (Prometheus)

Posted by : Steven Acreman | Monitoring

Running an online service isn't easy. Every day you make complex decisions about how to solve problems and often there is no right or wrong answer—just different ways with different results. On the infrastructure side, you have to weigh up where everything will be hosted: on a cloud service like AWS, or in your own data centres, or a combination of the two, or any number of other options.

Metrics: Nagios, Graphite, Prometheus & InfluxDB

Posted by : Steven Acreman | Monitoring

Open source monitoring can be quite confusing for those who haven't spent a lot of time reading about the options. At Outlyer, we track the most popular standards and then offer wire-compatible endpoints. This helps new customers migrate onto Outlyer with very little effort, and it means we don't invent yet another proprietary standard and create vendor lock-in.

Time-Series Database Benchmarks

Posted by : Steven Acreman | Dalmatimer DB

Our  Top10 Open Source Time Series databases blog has been very popular, with over 10,000 views and growing. It sat on the front page of Reddit /r/programming for a day or two and we got a bunch of traffic from HackerNews and DBWeekly. The raw data in the spreadsheet that accompanies the blog has been constantly updated ever since by a team of volunteers which now includes some of the database authors.

StatsD, Tags and Outlyer

Posted by : Steven Acreman | Monitoring

PLEASE NOTE:  in February 2017, we rebranded and changed our name from Dataloop.IO to Outlyer. Our agent is still called “dataloop agent”, and relevant code reflects the old name (Dataloop) as well. Thank you for your patience as we update everything.

We had a request today from one of our customers to look into supporting tags on StatsD metrics in Outlyer. The answer was so surprisingly easy I thought I'd do a blog post about it.
