Linux server monitoring is an important aspect of the entire network performance monitoring and IT operations management process if your network has Linux servers. Basic troubleshooting of Linux servers can be easily achieved using simple built-in commands, especially for monitoring CPU, memory, and processes. But that doesn't quite do the job of effective Linux server monitoring tools. A full-fledged, multi-faceted, all-in-one Linux server management tool is needed for a holistic monitoring approach. This is especially true for businesses and enterprises that want to ensure the best business-continuity experience for their organization and end users.
Monitoring Linux servers is more advantageous because:
Here are some of the challenges of Linux server monitoring:
OpManager is an all-in-one IT monitoring solution that provides unmatched real-time Linux server management and monitoring capabilities for various servers, including those running Linux. Important Linux server performance metrics like CPU, memory, and health can be monitored using OpManager. Multi-level thresholds can be set up for the important Linux server monitoring metrics to ensure they are constantly or periodically monitored.
To carry out Linux server performance monitoring, make sure either Telnet or SSH is enabled on the server. OpManager supports all major Linux distributions, such as Red Hat Enterprise, SUSE, Ubuntu, Fedora, Debian, and CentOS.
OpManager's Linux monitoring helps scrutinizes the health and availability of Linux servers via SNMP and CLI. If a device has both SNMP and CLI credentials associated with it, OpManager's Linux server management software will first try to fetch the processes via CLI and then via SNMP. You can monitor performance metrics such as overall resource usage, resource usage by workload, CPU usage, memory usage, disk I/O utilization, system load, network traffic, process details, thread count, process count, and more. From the pre-configured resource monitors, you can select CLI monitors and associate them to the required devices.
With OpManager's Linux server monitoring, you can also monitor hardware components in your Linux server including fan speed, temperature, power supply, and more to protect hardware and inturn server health. You can configure to receive alerts when a hardware component fails or encountering an issue via SMS, Email, web alarms and more.
OpManager's Linux server monitoring dashboard provides the holistic view of the status of your servers. It provides a graphical view of the performance metrics that allows you to get a glimpse of the server health. It also lets you quickly drill down to the root of the issue, in the event of downtime. You can customize the dahboard as Linux server performance monitoring dashboard, Linux server availability monitoring dashboard and more.
You can access the Linux server monitoring data in the form of reports with OpManager. With OpManager having over 100+ built-in reports, you'll always know what has happened in your network at a particular period of time. You can choose to have Top N reports on server performance or availability and use this information to analyse the issue when the server is acting up. You can also schedule reports to be notified to the concerned persons, not missing out on a single issue.
OpManager acts as a Linux process monitor, using both SNMP and CLI to fetch data on critical processes running on Linux, Solaris, Unix, HP-UX, and IBM AIX. Though, monitoring Linux server processes using CLI is one of the effective ways to collect data for monitoring. Such real-time monitoring of processes helps identify rogue processes and act upon them in a single click.
With server performance being constantly monitored, you can identify server performance issues such as high response time, latency, or packet loss in a jiffy and troubleshoot them with troubleshooting tools provided by OpManager. You can also automate certain troubleshooting L1 and L2 actions with Workflows. This way, not only you reduce MTTR to a greater extent but also maintain server uptime.
OpManager offers Linux-specific device templates. But first, let’s look at what device templates are. Device templates in OpManager are used to automatically associate a device model's details with a new or existing device in the network. A device template is pre-populated with device-related details such as device type, vendor, system description, and the object identifiers provided by the vendors' MIBs. The primary use of device templates in OpManager is to simplify initial Linux network management configurations for the end-user as pre-configured thresholds are applied automatically saving them some time. A secondary value-add would be that device details can be viewed in OpManager.
OpManager is Linux server management software that supports more than 10,000 device types and 450 device vendors, helping you efficiently discover, classify, and monitor the devices in your Linux network, thus simplifying the overall Linux network monitoring. This is possible with OpManager's plethora of monitoring metrics, wide range of supported devices such as routers, switches, servers, LANs, WLCs, printers, IP addresses, and more.
