NMIS8 performs server monitoring out of the box. NMIS8 supports Windows servers as well as the popular NET-SNMP SNMP daemon, which is widely used on Linux and other Unix systems. The core of NMIS server management is the Host Resources MIB, which is standardised in RFC2790, both the NET-SNMP, Windows SNMP and VMware ESXi daemons implement the Host Resources MIB.
NMIS8 has capabilities for performance and fault management of servers as well as service (application) monitoring running on servers.
NMIS8 collects and stores the following performance data from servers:
- Processor load
- Physical memory usage (not currently available from VMware ESXi)
- Virtual memory usage (not currently available from VMware ESXi)
- Disk usage (capacity and used)
- Network interface usage
Service Monitoring
- Checks Host Resources MIB for service status
- Performs poll of TCP/UDP port
- Runs a script which returns status (can perform full transaction over system and is highly extensible)
Windows Server Support
Depends on Windows SNMP Service (often referred to as agentless server monitoring). NMIS will collect the following information from Windows Servers in addition to the already described information.
- IP Utilisation
- Server Memory Pages per Sec
- CPU Interrupts
- Memory Stats (commited and available bytes)
- Number of Users
All of these information requires no Agent to be installed onto the Windows server other than the freely available Windows SNMP Service (part of the Windows installation and setup).
Unix Server Support
Depends on NET-SNMP daemon being installed and configured, usually installed by default on most Unix platforms. Instructions for installing the NET-SNMP daemon are included in the NMIS 8 Installation Guide.
