How We Ensure VividCortex Never Loses Data

Adrian Cockcroft really nailed it when he said that a monitoring system has to be more reliable than what it’s monitoring. I don’t mind admitting that in our first year or so, we had some troubles with losing telemetry data. Customers were never sure whether their systems were offline, the agents were down, or we were not collecting the data. Even a few seconds of missing data is glaringly obvious when you have 1-second resolution data.

Consul for Cluster Health Monitoring

If you’re not familiar with Consul, it’s what I call a cluster management tool. It’s composed of a handful of features such as “Service Discovery”, “Key Value Store”, “DNS Server”, “Health Checking”, and it’s “Data Center Aware”. It ultimately allows you to manage an infrastructure composed of many applications, dynamically configure them, route traffic to the healthy ones, and reroute traffic away from those that are not healthy. At VividCortex we don’t use most of Consul’s features (at least not yet).

The Five Stages of Debugging

Because it’s Friday afternoon and you may have had a long week, our brainiacs present… The Five Stages Of Debugging: Stage One. Denial - “What do you mean it’s broken!? That code has worked forever!” Stage Two. Anger - “[Explitive], now I have to fix this broken piece of crap…” Stage Three. Bargaining - “Hmm, maybe if I hack this bit up here that will fix it?” Stage Four. Depression - “It’s all broken, it can’t be fixed.

Updates To Our Fault Detection Algorithm

Unexpected downtime is one of your worst nightmares, but most attempts to find problems before they happen are threshold-based. Thresholds create noise, and alerts create false positives so often you may miss actual problems. When we began building VividCortex, we introduced Adaptive Fault Detection, a feature to detect problems through a combination of statistical anomaly detection and queueing theory. It’s our patent-pending technique to detect system stalls in the database and disk.

DBA Personalities: DISC and Values Models

What personality characteristics do great DBAs share? What motivates them? If you’re not sure why you should care, you’re probably not a hiring manager! Hiring and retaining highly skilled people is consistently listed as a top challenge for CIOs. CIOs strongly desire to predict whether someone’s a good fit for a particular role. Enter the personality profile assessment. These are quantitative tools used by many companies to try to learn as much as possible about candidates during the recruiting process.

Webinar June 2nd: Catena

Join us Tuesday, June 2nd at 2 PM EST (6 PM GMT), as brainiac Preetam Jinka covers the unique characteristics of time series data, time series indexing, and the basics of log-structured merge (LSM) trees and B-trees. After establishing some basic concepts, he will explain how Catena’s design is inspired by many of the existing systems today and why it works much better than its present alternatives. This webinar will help you understand the unique challenges of high-velocity time-series data in general, and VividCortex’s somewhat unique workload in particular.

Live-Updating Data For Continuous Monitoring

We’ve added a feature to VividCortex that will help you keep tabs on your systems more easily. At the top right corner of the app, near the time selector, you’ll see an auto-refresh widget: Click on this and it’ll change from a “play” to a “stop” icon. While it’s selected, the app will refresh once a minute and load an updated set of data. If you navigate anywhere or make any changes–basically, if you interact with the app–it’ll stop auto-refreshing so it doesn’t interfere with what you’re doing.

Introducing the Power of Notifications

Since VividCortex launched its database monitoring platform, many users have requested some type of notification system. To address this, we took particular care in building a feature that proactively warns users of potential problems without sending multiple false alerts. We are excited to announce notifications via email, PagerDuty and VictorOps. This post addresses basic functionalities, but please explore the feature and provide feedback to support@vividcortex.com. What triggers a notification? Our events dashboard records behaviors such as high swap activity, disc faults, replication stopping, mysql server restarts and more.

Daily Reports Send Top Queries to Your Inbox

We know you are busy, and checking the VividCortex interface is not always on the top of your priority list. That’s why we implemented our proactive reporting feature. Each day, your team will receive a recap of the top ten queries of each environment from the day prior. You can see at a glance whether systems were running smoothly or if you need to look into performance. If daily reports are creating too much noise, you can subscribe to weekly reports instead.

Improvements in VividCortex's Query Digesting Algorithm

At VividCortex, the algorithm our agents use to digest queries needs to be fast and reliable. Accurately digesting queries into logical groups is important to providing a useful view of data in the UI - digest too few or too many and it becomes difficult to understand what the Top-Queries view is showing. Though our algorithm is sophisticated, one of our PostgreSQL clients experienced an issue with query digestion. They had many queries of the form “select a,b,c from table where c = any(values (1), (2), (3)…)” which were not being collapsed correctly.

Potential Perils of Using Google Calendar and Hangouts

Lots of businesses are using Google Apps, and with good reason. Google Calendar streamlines schedule coordination and is especially vital to use with sales prospects because the opportunity cost of getting a timezone wrong or having a prospect fail to show up is too high. However, the Google approach still has a couple problems. First, Google Hangout is possibly the single worst way to have a call due to all kinds of plugin and permission issues.

How VividCortex Uses Redis

Last week, we introduced VividCortex support for Redis. One of the reasons we expanded our product capabilities is because of our own use of Redis. According to Baron, “We rely on Redis to help analyze the massive amounts of time-series data we receive from agents running on customer systems.” Let’s go a little deeper… VividCortex keeps tables with all the known metrics and queries for many hosts measured at 1-second granularity.
