php snmptrap handler and web UI for management

php-snmptraps is an php trpahandler that processes snmp traps, writes them to database and/or file and sends notifications via sms/email/pushover to users, based on web settings.

It comes with nice HMTL5 UI:

• Dashboard that shows overview of last messages
• Displays messages sent by specific host
• Displays messages per severity
• Displays specific messages received
• Live update of received traps

and more.

You can set severity level for each received message, ignore specific message types, create maintenance periods for hosts, set per-user quiet hours and more.

Notifications are set per-user/severity, by default aupported are:

• Email notification
• Pushover notification
• SMS notification
• Slack/Mattermost notification

The can be easily extended to any other custom notification type.

setup

This guide assumes you have a working net-snmp, apache, php and mysql installation with default apache files stored in /var/www/.

1.Set traphandler

First, edit file /etc/snmp/snmptrapd.conf and add traphandler for default files to traphandler.php:

# listen on
agentaddress my_ip_address:162
# set php-snmptraps as default trap handler
traphandle default /usr/bin/php /var/www/traphandler.php

2.Prepare and edit config file

Now go to /var/www/ directory and copy config.dist.php to config.php:

cp /var/www/config.dist.php /var/www/config.php

and edit the config file to match your settings.

3.Set mod_rewrite

mod_rewrite is required for snmptraps. Example here:

4.Import database schema

Now you have to import chema for mysql database with following command:

mysql -u root -p
Enter password:

mysql> create database snmptraps;
Query OK, 1 row affected (0.00 sec)

mysql> GRANT ALL on snmptraps.* to snmptraps@localhost identified by "snmptraps";
Query OK, 0 rows affected (0.00 sec)

mysql> exit
Bye

# import SCHEMA.SQL file
mysql -u root -p snmptraps < db/SCHEMA.sql

That should be it, fire up browser and login. Default user/pass is Admin/snmptraps.

5.Send test message and debugging

To test snmptrap you can use the following command:

snmptrap -v 2c -c public my_public_ip '' .1.3.6.1.4.1.2636.4.1.1 .1.3.6.1.4.1.2636.4.1.1 s "Power supply failure"

Check also the file you set in config.php for possible errors:

tail -f /tmp/trap.txt
