Enhanced SNMP Interface Discovery

Description

Enhanced SNMP interface discovery 1.0.1 Template made by Twan Kamans. https://www.twan-it.nl This template searches for 4 different categories: - Interfaces that are administratively disabled - Interfaces that are working onder normal condition - Interfaces with priority, such as switch uplink - Virtual interfaces such as tunnel, port channel and vlan interfaces. Revision 0.7 - Added support for virtual interfaces Revision 0.7.1 - Added support for (filtering) stack switch ports - Fixed a bug in which VLAN interfaces with the number 0 in them would still be discovered by the normal LLD rule Revision 0.7.2 - Filtering VLAN’s 1002 - 1005 interfaces - Added support for subinterfaces for Junos Revision 0.8 - Completely revisited the filtering of items using Regex due to introduction of Junos devices. You can adjust the regex for physical devices using a macro. Revision 0.9 - Added support for enduser ports. Triggers will not activate if port description contains macro value. Revision 1.0 - Tested template on posible errors. Revision 1.0.1 - Added bandwidth statistics for virtual interfaces. Revision 1.0.2 - Bandwidth triggers now make use of user macro context, making individual port bandwidth limits posible. - The interface changed state severity has been lowered by default. The new default severity for all interfaces is “warning”. Exceptions to this are the priority interfaces which are “average”.

Overview

This template is a replacement for the great default SNMP interface template. It uses the default SNMP interface library and OID’s, meaning that it’s compatible with a lot of devices.

The template has the following features:

Priority interfaces (assign higher severity triggers to your important interfaces)
Get notified when a user no-shut’s a port
Get notified when a port is in the not-connected state
Get notified when the bandwidth of a port reaches a specific threshold in percentage (port specific using user macro context)
Get notified when a port changes that (up / down)
Adjustable LLD timer for working on port configurations which quickly need to be discovered by Zabbix
Only gather data for items and interfaces that are important: i don’t want to monitor loopback interfaces and the amount of incoming errors on a port-channel (notsupported items)
Don’t trigger on (switch)ports which have users behind them. I don’t want to know when someone turns their computer off.

Most of these features can be adjusted and enabled / disabled using macro’s:

{$INT_BANDWIDTH_WARNING}
{$INT_ERRORS_WARN}
{$INT_LLD_UPDATE_INTERVAL}
{$INT_NAME_PHYSICAL}
{$INT_NO_TRIGGER_STRING}
{$INT_PRIO_STRING}
{$SEARCH_FOR_INACTIVE_PORTS}

Macro name	Default value	Type	Description
{$INT_BANDWIDTH_WARNING}	80	Percentage	Percentage when trigger fires
{$INT_ERRORS_WARM}	2	#Amount	Max error value for “interface errors trigger”
{$INT_LLD_UPDATE_INTERVAL}	30m	Time	Update interval for LLD rules
{$INT_NAME_PHYSICAL}	^[A-Z	a-z]{2}-?[0-9]+\/[0-9]{1,2}(\/[0-9]+)?$	Regex	Regex that filters the physical interfaces
{$INT_NO_TRIGGER_STRING}	^(EDGEPORT)$	Regex	Regex for edge ports (computers turning on / off)
{$INT_PRIO_STRING}	UPLINK	Regex	Description keyword for priority interfaces
{$SEARCH_FOR_INACTIVE_PORTS}	0	Bolean	0 = Does not trigger for notconnected ports (1 does)

With the default values, interface descriptions that start with “UPLINK” will be discovered by the Priority LLD. Interfaces that contain the keyword EDGEPORT will not generate a trigger when turned on / off.

If you miss some interfaces: run a SNMPWALK over the device to check if it matches the {$INT_NAME_PHYSICAL} regex!

Don’t trigger on (switch)ports which have users behind them. I don’t want to know when someone turns their computer off.

Most of these features can be adjusted and enabled / disabled using macro’s:

{$INT_BANDWIDTH_WARNING}
{$INT_ERRORS_WARN}
{$INT_LLD_UPDATE_INTERVAL}
{$INT_NAME_PHYSICAL}
{$INT_NO_TRIGGER_STRING}

{$SEARCH_FOR_INACTIVE_PORTS}

Macro name	Default value	Type	Description
{$INT_BANDWIDTH_WARNING}	80	Percentage	Percentage when trigger fires
{$INT_ERRORS_WARM}	2	#Amount	Max error value for “interface errors trigger”
{$INT_LLD_UPDATE_INTERVAL}	30m	Time	Update interval for LLD rules
{$INT_NAME_PHYSICAL}	^[A-Z	a-z]{2}-?[0-9]+\/[0-9]{1,2}(\/[0-9]+)?$	Regex	Regex that filters the physical interfaces
{$INT_NO_TRIGGER_STRING}	^(EDGEPORT)$	Regex	Regex for edge ports (computers turning on / off)
{$INT_PRIO_STRING}	UPLINK	Regex	Description keyword for priority interfaces
{$SEARCH_FOR_INACTIVE_PORTS}	0	Bolean	0 = Does not trigger for notconnected ports (1 does)

If you miss some interfaces: run a SNMPWALK over the device to check if it matches the {$INT_NAME_PHYSICAL} regex!

Enhanced SNMP Interface Discovery

Description

Overview

This template is a replacement for the great default SNMP interface template. It uses the default SNMP interface library and OID’s, meaning that it’s compatible with a lot of devices.

The template has the following features:

Priority interfaces (assign higher severity triggers to your important interfaces)
Get notified when a user no-shut’s a port
Get notified when a port is in the not-connected state
Get notified when the bandwidth of a port reaches a specific threshold in percentage (port specific using user macro context)
Get notified when a port changes that (up / down)
Adjustable LLD timer for working on port configurations which quickly need to be discovered by Zabbix
Only gather data for items and interfaces that are important: i don’t want to monitor loopback interfaces and the amount of incoming errors on a port-channel (notsupported items)
Don’t trigger on (switch)ports which have users behind them. I don’t want to know when someone turns their computer off.

Most of these features can be adjusted and enabled / disabled using macro’s:

{$INT_BANDWIDTH_WARNING}
{$INT_ERRORS_WARN}
{$INT_LLD_UPDATE_INTERVAL}
{$INT_NAME_PHYSICAL}
{$INT_NO_TRIGGER_STRING}
{$INT_PRIO_STRING}
{$SEARCH_FOR_INACTIVE_PORTS}

Macro name	Default value	Type	Description
{$INT_BANDWIDTH_WARNING}	80	Percentage	Percentage when trigger fires
{$INT_ERRORS_WARM}	2	#Amount	Max error value for “interface errors trigger”
{$INT_LLD_UPDATE_INTERVAL}	30m	Time	Update interval for LLD rules
{$INT_NAME_PHYSICAL}	^[A-Z	a-z]{2}-?[0-9]+\/[0-9]{1,2}(\/[0-9]+)?$	Regex	Regex that filters the physical interfaces
{$INT_NO_TRIGGER_STRING}	^(EDGEPORT)$	Regex	Regex for edge ports (computers turning on / off)
{$INT_PRIO_STRING}	UPLINK	Regex	Description keyword for priority interfaces
{$SEARCH_FOR_INACTIVE_PORTS}	0	Bolean	0 = Does not trigger for notconnected ports (1 does)

If you miss some interfaces: run a SNMPWALK over the device to check if it matches the {$INT_NAME_PHYSICAL} regex!
