In your opinion, what do these three events have in common: A social network (VK) user posts a new photo; someone uses Assist to make an online purchase with a bank card; and car is brought to CarPrice and appears in the auction stream.
Once you’ve acquired and set up your dedicated or virtual server, the next step is to establish a monitoring system. Monitoring keeps you up-to-date on your service’s status by regularly checking your site’s main subsystems. Read more
In May 2016, the developers of Sysdig released Falco, a tool for detecting anomalous system behavior.
Falco consists of two main components: the sysdig_probe kernel module (which Sysdig also runs on) and the daemon for writing the information it collects to the disk.
Falco tracks applications according to user-defined rules, and if any anomalies are detected, it writes the information to a standard output, syslog, or user-defined file. in their blog, the developers jokingly call Falco “…a hybrid of snort, ossec and strace,” and position it as a simple IDS that puts almost no additional load on the system.
In previous posts, we looked at various issues related to monitoring, collecting, and saving metrics and different methods and tools for getting around them. In today’s article, we’ll be discussing yet another tool that simplifies these processes: Netdata.
Unlike other analytical tools, Netdata is designed for gathering and visualizing metrics in real time (and when necessary, a backend can be incorporated for gathering and saving collected metrics).
We sometimes meet with clients to find out what they’re working on, what problems they encounter, and what role Selectel plays in all of it. Once such company from St. Petersburg is called Datagrav, and we recently discussed these topics with their CEO, Sergey Kochuguyev.
Today, online services should be available 24 hours a day, 7 days a week, 365 days a year. Limited access and downtime can cost a company not only profits, but its reputation, too. To keep you up-to-date on your service’s availability, we’ve developed our own monitoring tool.
