When we detect something wrong with your site (it is down, a broken link is detected, the certificate is invalid, ...), we can notify you via one of the many notification channels we support. One of those channels is Pushover, an excellent service to send native notifications to mobile devices. We have supported Pushover since we launched a couple of years ago. Now, we've added a nice option that several of our users we're asking for: setting the priority.

When the Citrix architecture moved from v6 to v7, one of the main components that was introduced in the v7 architecture was the Citrix Delivery Controller (CDC). A Citrix Delivery Controller is a server-side component that is responsible for managing user access and brokering (enabling application and desktop access) and optimizing connections. Each site will have one or more delivery controllers.

Recently, my colleagues Pete Di Stefano, Ashley Adams, and I hosted a webcast on the topic of capacity planning and optimization. You can listen/watch it here, it was a really fun conversation. As part of the discussion, we talked about the need to measure the right things to get the correct outcome. Keep in mind my oft-repeated mantra: monitoring is simply the collection of data. You need a robust, mature tool to add context, which transforms those metrics into information.

On this day in 1889, William Gray patented the first coin operated telephone with the first model installed at the Hartford Bank in Connecticut.

Keeping the experience of your end user in mind is important when developing applications. Observability tools help your team measure important performance indicators that are important to your users, like uptime. It’s generally a good practice to measure your service internally via metrics and logs which can give you indications of uptime, but an external signal is very useful as well, wherever feasible.

“Observability,” is the process in DataOps of recording data generated by digital systems as they go about their processes. There are some great companies in the observability space, generating a whopping $17 billion annually, and contributing a significant portion to the modest 2.5 quintillion bytes of data created every year.

The Four Golden Signals of monitoring and observability get a lot of things right. But they could be even better.

The past year has been significant for continued development of both DevOps practices and new developments across the open source community. To that end, Logz.io is moving forward with renewed support for the Fluentd log shipper. This new proxy will serve as an alternative to Filebeat and Logstash, which recently moved away from open source licensing. Additionally, this integration utilizes an HTTP proxy instead of the SOCKS5 proxy necessary for Filebeat.

In the era of data abundance, there exists a significant need for database systems that can effectively manage large quantities of data. For certain types of applications, an oft-considered option is Apache Cassandra. Like any other piece of software, however, Cassandra has issues that could potentially impact performance. When this happens, it’s critical to know where to look and what to look for in the effort to quickly restore service to an acceptable level.

If you are a candidate looking for your next role that involves an in-depth knowledge of Elasticsearch and the wider Elastic Stack then you will want to revise beforehand. In this resource guide on the top ELK interview questions, we've listed all of the leading questions that candidates are commonly asked about Elasticsearch, Logstash & Kibana (and their contemporary tools and plugins) alongside the answers.
