Web monitor linux12/3/2023 ![]() ![]() Server Monitoring with the Local Web Monitor. An alert for (almost) full memory is therefore not practical. Avoid server outages by monitoring critical server parameters like memory, fixed disk, load via the HTTP. However, Linux is intelligent enough to take the size of application processes into account, and therefore it pushes processes into a SWAP before the RAM is full. Memory management does not work according to the overflow principle. By default, you often only look at the RAM. For example, there is a relationship between RAM and SWAP that is relevant for monitoring. This should be considered when monitoring servers. You should of course follow the best practices for server monitoring.Įxperience has also shown that Linux itself has internal mechanisms for improving server performance. ![]() Linux servers are considered robust, but an operating system alone does not protect against problems or configuration errors. IPMI), and is in no way limited to agents. Checkmk supports integration with almost all common protocols (such as SNMP), APIs and interfaces (e.g. Integrations for Checkmk are available in all common virtualization solutions, so that not only virtual servers, but also the monitoring of their platforms such as VMWare ESXi or Microsoft Hyper-V is possible.Īgents are also not a requirement for monitoring. Nevertheless, all Nagios plug-ins can also be integrated into Checkmk. Step 1: Installing Monit in Linux By default, the Monit monitoring program is not available from the default system base repositories, you need to add and enable a third-party epel repository to install the monit package under RHEL-based distributions such as CentOS, Rocky Linux, and AlmaLinux. ![]() The Enterprise Edition, on the other hand, uses the Checkmk Micro Core, and is therefore a completely independent development. The Checkmk Raw Edition still uses the Nagios core for monitoring. Historically, Checkmk started as a Nagios fork, but for many years it has been a completely independent product. Over the years Checkmk has matured into an extensive, all-in-one platform, and yet it has retained its classic Linux qualities: good documentation, lean and secure architecture, expansion options, and stable performance.Īt the same time, however, it places great value on a high degree of user-friendliness. Monitoring tools require continuous development. In addition, integration with external tools such as Grafana is also supported. You can tailor metrics and analysis to the needs of specialists and IT experts using integrated graphing, dashboarding, and reporting engines. Checkmk is easy to install, and its administration takes place entirely via the Graphical User Interface (GUI). ![]()
