4. Modeling Devices Using SNMP

Read this section for information about the methods Zenoss uses to model devices using SNMP.

4.1. Testing to See if a Device is Running SNMP

To test whether a device is running SNMP, run this command:

$ snmpwalk -v1 -c communityString Gate system

If this command does not time out, then SNMP is installed and working correctly.

4.2. Modeling Remote Windows Devices Using SNMP

By default, Windows may not have SNMP installed. To install SNMP, follow these general steps:

  1. Go to Start > Control Panel > Add or Remove Programs > Add/Remove Windows Components.

  2. Select the option for Management and Monitoring tools and install them.

  3. Go to Control Panel > Administrative Tools > Services and start the SNMP Service and SNMP Trap Service.

  4. Set the SNMP Community string in the SNMP Service properties to the community string of your SNMP.

If you want processor and memory monitoring, install SNMP-Informant on the device. Go to http://www.snmp-informant.com and download SNMP for Windows.

To collect Windows Event logs or log files from a Windows box using syslog, you can use the SyslogAgent Windows add-on, available from:

http://syslogserver.com/syslogagent.html

4.3. Modeling Remote Linux Devices Using SNMP

To configure a Linux machine for monitoring, it must have SNMP installed. A good Linux SNMP application is net-snmp. Download, install, and configure net-snmp to then use SNMP to monitor Linux devices with Zenoss.

4.4. Modeling Cisco Devices Using SNMP

Cisco devices come with SNMP already installed. However, you have to configure SNMP on each Cisco device to be in the same community as the rest of your network.
