FreeBSD Monitoring
Processes, memory, disks, file systems, logged-in users and network interfaces of FreeBSD systems in a single package of checks.
Hardware and operating system under control
FreeBSD is a high-performance open source operating system used by many modern server platforms: it offers advanced networking features and strong security characteristics, which is why some of the most popular web applications choose it.
The Sentinet³ FreeBSD Pattern provides full access to the hardware and monitoring at FreeBSD operating system level. Administrators can follow each running process and see its status, the memory it uses and its CPU consumption.
The Pattern also makes it possible to monitor system events by accessing logs, configuration files and login events.

| Scope | Hardware, operating system, processes, network interfaces |
The Pattern’s checks
Every check has operator-configurable thresholds and sends notifications when values exceed them.
System
| Check | What it verifies |
|---|---|
| Reachability | The machine responds on the network |
| Swap_memory | Percentage of swap memory used |
| Physical_memory | Percentage of physical memory in use |
| Disk I/O stat | Reads and writes per second and transfers per second, for each device |
| Home | Free space in the home directory |
| Root | Free space in the root directory |
| Var | Free space in the var directory |
| Usr | Free space in the usr directory |
| CPU | Percentage of CPU used |
| Process | Running processes |
| User | Number of logged-in users |
Network interfaces
With a single query to the server, the Pattern returns this information for each interface.
| Check | What it verifies |
|---|---|
| Status | Interface status, up or down |
| IP address | IP address of the interface |
| MAC | MAC address of the interface |
| Speed | Interface speed, in Mbit |
| Packet Error | Number of packets with errors |
| Traffic | Inbound and outbound traffic |
What the collected data is used for
- Performance diagnostics: logs, configuration files and login events help identify the causes of system performance problems.
- Security policies: the same data supports the enforcement of security policies.
- Impact analysis: the effects of every configuration change in the FreeBSD environment can be assessed.
- Process by process: the status, memory and CPU of each process make it possible to act on the single service that is causing problems.
