SNMP traps contain information sent from a monitored host to a monitoring server using the SNMP protocol.

Trap definition files are used to define the actions to be performed when a Box receives an SNMP trap.

To use service templates based on SNMP traps, specific prerequisites must first be met.

• You configure these prerequisites once only.
• This is done in two steps:
  • Configure the Box to receive SNMP traps using a script that will install the SNMPTT package and copy the required configuration files. A rule will be added to IPTABLES to enable the Box to receive traffic via port 162.
  • Create trap definition files to define the actions to be performed when an SNMP trap is received.  See the detailled procedure.

Notes

• You can obtain the SN-trapInstall.sh install script from the EasyVista Support team.
• You must have root access rights.
• The Box must be able to access the Internet so that the script can install certain packets using an apt-get install.

Caution

• The apt-get install command may cause malfunctioning issues in MS SQL services. If this is the case, you should run the command below to delete the symbolic link.

Procedure: How to configure SNMP trap monitoring prerequisites

Step 1: Configure the Box to receive SNMP traps

1. Install the archive required for configuring the Box.

• Go to the TOOLS section in the folder containing the masters.
• Download the file called SN-trapInstallation-v3.tar.gz to the Box /tmp folder.
• Run the commands below to extract the files from the archive.

The snmptrapd, snmptrapd.conf and snmptt.ini configuration files will be copied to the /tmp folder.

• Run the commands below to update libraries using the install script.

2. (optional) Modify the default value of the SNMP community that sends the traps.

• Run the command below to open the snmptrapd.conf configuration file.

• Search for the row, authCommunity execute <community>.
• Replace the <community> value with the value of the SNMP community you want.
• Save your modifications.
• Run the command below to restart the snmptrad service.

The Box can now receive SNMP traps.
