Web servers are among the most important components in modern IT infrastructures. They host the websites, web services, and web applications that we use on a daily basis. Social networking, media streaming, software as a service (SaaS), and other activities wouldn’t be possible without the use of web servers. And with the advent of cloud computing and the movement of more services online, web servers and their monitoring are only becoming more important.
The Apache HTTP Server (Apache HTTPd) is one of the most popular open source web servers available. HTTPd was also the first project developed by the Apache Software foundation which now supports hundreds of well known projects including Kafka, Cassandra and Hadoop. Netdata has a public demo space where you can explore different monitoring use-cases. Check out the Apache demo room to explore and interact with the charts and metrics described here.
The health management APIs in Netdata allows teams to eliminate unnecessary alerting during scheduled maintenance, testing, auto scaling events, and instance reboots. For all SREs, it is absolutely crucial to filter out expected events during maintenance windows and quickly pinpoint critical issues in your infrastructure. Every minute is crucial while dealing with troubleshooting issues and any distractions that may hijack the troubleshooting process should be subdued.
Monitoring indoor air quality with Airthings and Netdata. Understanding and measuring common contaminants and pollutants reduces your risk of air quality health concerns.
Monitoring KSM (Kernel Same-page Merging) performance at deduping memory shared across VMs.
Netdata’s Cassandra collector documentation explains how to set it up to collect metrics automatically. Once you have followed the instructions in the docs and have installed and configured Netdata on the Cassandra cluster you are ready to start monitoring and troubleshooting.
Database bloat is disk space that was used by a table or index and is available for reuse by the database but has not been reclaimed. Bloat is created when deleting or updating tables and indexes. Here's how to deal with it!
What are the important Cassandra metrics to monitor and how to monitor them.
We often hear the term load used to describe the state of a server or a device, but we're here to tell you what it means, precisely, and how to monitor it.
The most important part of disk usage monitoring is to check the utilization of each filesystem and each mount point which can reveal existing or impending issues with the storage space on your infrastructure.
